A simple linear transfer function, with good accuracy near 25°C, is VO= −11.69 mV/°C × T + 1.8663 V (1) Over the full operating temperature range of −55°C to +130°C, best accuracy can be obtained by using the parabolic transfer function VO = (−3.88×10−6×T2) + (−1.15×10−2×T) + 1.8639 (2) solving for T: (3) A linear transfer function can be used over a limited temperature range by calculating a slope and offset that give best results over that range. A linear transfer function can be calculated from the parabolic transfer function of the LM19. The slope of the linear transfer function can be calculated using the following equation: m = −7.76 × 10−6× T − 0.0115 where • T is the middle of the temperature range of interest and m is in V/°C. (4) For example for the temperature range of Tmin = −30 to Tmax = +100°C: T = 35°C and m = −11.77 mV/°C The offset of the linear transfer function can be calculated using the following equation: b = (VOP(Tmax) + VOP(T) − m × (Tmax+T))/2 where • VOP(Tmax) is the calculated output voltage at Tmax using the parabolic transfer function for VO. • VOP(T) is the calculated output voltage at T using the parabolic transfer function for VO. (5) Using this procedure the best fit linear transfer function for many popular temperature ranges was calculated in Table 1. As shown in Table 1 the error that is introduced by the linear transfer function increases with wider temperature ranges.

It can be glued or cemented to a surface. The temperature that the LM19 is sensing will be within about +0.02°C of the surface temperature to which the LM19's leads are attached. This presumes that the ambient air temperature is almost the same as the surface temperature; if the air temperature were much higher or lower than the surface temperature, the actual temperature measured would be at an intermediate temperature between the surface temperature and the air temperature. To ensure good thermal conductivity the backside of the LM19 die is directly attached to the GND pin. The tempertures of the lands and traces to the other leads of the LM19 will also affect the temperature that is being sensed. Alternatively, the LM19 can be mounted inside a sealed-end metal tube, and can then be dipped into a bath or screwed into a threaded hole in a tank. As with any IC, the LM19 and accompanying wiring and circuits must be kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may operate at cold temperatures where condensation can occur. Printed-circuit coatings and varnishes such as Humiseal and epoxy paints or dips are often used to ensure that moisture cannot corrode the LM19 or its connections. The thermal resistance junction to ambient (θJA) is the parameter used to calculate the rise of a device junction temperature due to its power dissipation. For the LM19 the equation used to calculate the rise in the die temperature is as follows: TJ = TA + θJA [(V+ IQ) + (V+ − VO) IL] where • IQ is the quiescent current and ILis the load current on the output. (6) Since the LM19's junction temperature is the actual temperature being measured care should be taken to minimize the load current that the LM19 is required to drive. Table 2 summarizes the rise in die temperature of the LM19 without any loading, and the thermal resistance for different conditions. Table 2.

Without any precautions, the LM19 can drive any capacitive load less than 300 pF as shown in Figure 3. Over the specified temperature range the LM19 has a maximum output impedance of 160 Ω. In an extremely noisy environment it may be necessary to add some filtering to minimize noise pickup. It is recommended that 0.1 μF be added from V+ to GND to bypass the power supply voltage, as shown in Figure 4. In a noisy environment it may even be necessary to add a capacitor from the output to ground with a series resistor as shown in Figure 4. A 1 μF output capacitor with the 160 Ω maximum output impedance and a 200 Ω series resistor will form a 442 Hz lowpass filter. Since the thermal time constant of the LM19 is much slower, the overall response time of the LM19 will not be significantly affected. Figure 3.

Suggested Connection to a Sampling Analog to Digital Converter Input Stage Most CMOS ADCs found in ASICs have a sampled data comparator input structure that is notorious for causing grief to analog output devices such as the LM19 and many op amps. The cause of this grief is the requirement of instantaneous charge of the input sampling capacitor in the ADC. This requirement is easily accommodated by the addition of a capacitor. Since not all ADCs have identical input stages, the charge requirements will vary necessitating a different value of compensating capacitor. This ADC is shown as an example only. If a digital output temperature is required please refer to devices such as the LM74. 8 Submit Documentation Feedback Copyright © 2001–2013, Texas Instruments Incorporated Product Folder Links: LM19 LM19 www.ti.com SNIS122E –MAY 2001–REVISED MARCH 2013 REVISION HISTORY Changes from Revision D (March 2013) to Revision E Page • Changed layout of National Data Sheet to TI format ............................................................................................................ 8 Copyright © 2001–2013, Texas Instruments Incorporated Submit Documentation Feedback 9 Product Folder Links: LM19 PACKAGE OPTION ADDENDUM www.ti.com 18-Oct-2013 Addendum-Page 1 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Qty Eco Plan (2) Lead/Ball Finish (6) MSL Peak Temp (3) Op Temp (°C) Device Marking (4/5) Samples LM19CIZ/LFT4 ACTIVE TO-92 LP 3 2000 Green (RoHS & no Sb/Br) SN | CU SN N / A for Pkg Type LM19 CIZ LM19CIZ/NOPB ACTIVE TO-92 LP 3 1800 Green (RoHS & no Sb/Br) SN | CU SN N / A for Pkg Type -55 to 130 LM19 CIZ (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.

Package Types Description The MCP3421 is a single channel low-noise, high accuracy ΔΣ A/D converter with differential inputs and up to 18 bits of resolution in a small SOT-23-6 package. The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially (Δ voltage = 4.096V). The device uses a two-wire I2C compatible serial interface and operates from a single 2.7V to 5.5V power supply. The MCP3421 device performs conversion at rates of 3.75, 15, 60, or 240 samples per second (SPS) depending on the user controllable configuration bit settings using the two-wire I2C serial interface. This device has an on-board programmable gain amplifier (PGA). The user can select the PGA gain of x1, x2, x4, or x8 before the analog-to-digital conversion takes place. This allows the MCP3421 device to convert a smaller input signal with high resolution. The device has two conversion modes: (a) Continuous mode and (b) One-Shot mode. In One-Shot mode, the device enters a low current standby mode automatically after one conversion. This reduces current consumption greatly during idle periods. The MCP3421 device can be used for various high accuracy analog-to-digital data conversion applications where design simplicity, low power, and small footprint are major considerations.

The MCP3421 device accepts a fully differential analog input signal which is connected on the VIN+ and VINinput pins. The differential voltage that is converted is defined by VIN = (VIN+ - VIN-) where VIN+ is the voltage applied at the VIN+ pin and VIN- is the voltage applied at the VIN- pin. The input signal level is amplified by the programmable gain amplifier (PGA) before the conversion. The differential input voltage should not exceed an absolute of (2* VREF/PGA) for accurate measurement, where VREF is the internal reference voltage (2.048V) and PGA is the PGA gain setting. The converter output code will saturate if the input range exceeds (2* VREF/PGA). The absolute voltage range on each of the differential input pins is from VSS-0.3V to VDD+0.3V. Any voltage above or below this range will cause leakage currents through the Electrostatic Discharge (ESD) diodes at the input pins. This ESD current can cause unexpected performance of the device. The common mode of the analog inputs should be chosen such that both the differential analog input range and the absolute voltage range on each pin are within the specified operating range defined in Section 1.0 “Electrical Characteristics” and Section 4.0 “Description of Device Operation”. 3.2 Supply Voltage (VDD, VSS) VDD is the power supply pin for the device. This pin requires an appropriate bypass capacitor of about 0.1 μF (ceramic) to ground. An additional 10 μF capacitor (tantalum) in parallel is also recommended to further attenuate high frequency noise present in some application boards. The supply voltage (VDD) must be maintained in the 2.7V to 5.5V range for specified operation. VSS is the ground pin and the current return path of the device. The user must connect the VSS pin to a ground plane through a low impedance connection. If an analog ground path is available in the application PCB (printed circuit board), it is highly recommended that the VSS pin be tied to the analog ground path or isolated within an analog ground plane of the circuit board. 3.3 Serial Clock Pin (SCL) SCL is the serial clock pin of the I2C interface. The MCP3421 acts only as a slave and the SCL pin accepts only external serial clocks. The input data from the Master device is shifted into the SDA pin on the rising edges of the SCL clock and output from the MCP3421 occurs at the falling edges of the SCL clock. The SCL pin is an open-drain N-channel driver. Therefore, it needs a pull-up resistor from the VDD line to the SCL pin. Refer to Section 5.3 “I2C Serial Communications” for more details of I2C Serial Interface communication. 3.4 Serial Data Pin (SDA) SDA is the serial data pin of the I2C interface. The SDA pin is used for input and output data. In read mode, the conversion result is read from the SDA pin (output). In write mode, the device configuration bits are written (input) though the SDA pin. The SDA pin is an opendrain N-channel driver. Therefore, it needs a pull-up resistor from the VDD line to the SDA pin. Except for start and stop conditions, the data on the SDA pin must be stable during the high period of the clock. The high or low state of the SDA pin can only change when the clock signal on the SCL pin is low. Refer to Section 5.3 “I2C Serial Communications” for more details of I2C Serial Interface communication.

DS22003B-page 7 MCP3421 4.0 DESCRIPTION OF DEVICE OPERATION 4.1 General Overview The MCP3421 is a low-power, 18-Bit Delta-Sigma A/D converter with an I2C serial interface. The device contains an on-board voltage reference (2.048V), programmable gain amplifier (PGA), and internal oscillator. The user can select 12, 14, 16, or 18 bit conversion by setting the configuration register bits. The device can be operated in Continuous Conversion or One-Shot Conversion mode. In the Continuous Conversion mode, the device converts the inputs continuously. While in the One-Shot Conversion mode, the device converts the input one time and stays in the low-power standby mode until it receives another command for a new conversion. During the standby mode, the device consumes less than 0.1 μA typical. 4.2 Power-On-Reset (POR) The device contains an internal Power-On-Reset (POR) circuit that monitors power supply voltage (VDD) during operation. This circuit ensures correct device start-up at system power-up and power-down events. The POR has built-in hysteresis and a timer to give a high degree of immunity to potential ripples and noises on the power supply. A 0.1 μF decoupling capacitor should be mounted as close as possible to the VDD pin for additional transient immunity. The threshold voltage is set at 2.2V with a tolerance of approximately ±5%. If the supply voltage falls below this threshold, the device will be held in a reset condition. The typical hysteresis value is approximately 200 mV. The POR circuit is shut-down during the low-power standby mode. Once a power-up event has occurred, the device requires additional delay time (approximately 300 μs) before a conversion can take place. During this time, all internal analog circuitries are settled before the first conversion occurs. Figure 4-1 illustrates the conditions for power-up and power-down events under typical start-up conditions. When the device powers up, it automatically resets and sets the configuration bits to default settings. The default configuration bit conditions are a PGA gain of 1 V/V and a conversion speed of 240 SPS in Continuous Conversion mode. When the device receives an I2C General Call Reset command, it performs an internal reset similar to a Power-On-Reset event. FIGURE 4-1: POR Operation. 4.3 Internal Voltage Reference The device contains an on-board 2.048V voltage reference. This reference voltage is for internal use only and not directly measurable. The specifications of the reference voltage are part of the device’s gain and drift specifications. Therefore, there is no separate specification for the on-board reference. 4.4 Analog Input Channel The differential analog input channel has a switched capacitor structure. The internal sampling capacitor (3.2 pF) is charged and discharged to process a conversion. The charging and discharging of the input sampling capacitor creates dynamic input currents at the VIN+ and VIN- input pins, which is inversely proportional to the internal sampling capacitor and internal frequency. The current is also a function of the differential input voltages. Care must be taken in setting the common-mode voltage and input voltage ranges so that the input limits do not exceed the ranges specified in Section 1.0 “Electrical Characteristics”. 4.5 Digital Output Code The digital output code produced by the MCP3421 is a function of PGA gain, input signal, and internal reference voltage. In a fixed setting, the digital output code is proportional to the voltage difference between the two analog inputs. The output data format is a binary two’s complement. With this code scheme, the MSB can be considered a sign indicator. When the MSB is a logic ‘0’, it indicates a positive value. When the MSB is a logic ‘1’, it indicates a negative value. The following is an example of the output code: (a) for a negative full-scale input voltage: 100...000 (b) for a zero differential input voltage: 000...000 (c) for a positive full-scale input voltage: 011...111. The MSB is always transmitted first through the serial port. The number of data bits for each conversion is 18, 16, 14, or 12 bits depending on the conversion mode selection.

The output codes will not roll-over if the input voltage exceeds the maximum input range. In this case, the code will be locked at 0111...11 for all voltages greater than +(VREF - 1 LSB) and 1000...00 for voltages less than -VREF. Table 4-2 shows an example of output codes of various input levels using 18 bit conversion mode. Table 4-3 shows an example of minimum and maximum codes for each data rate option. The output code is given by: EQUATION 4-1: The LSB of the code is given by: EQUATION 4-2: TABLE 4-1: LSB SIZE OF VARIOUS BIT CONVERSION MODES TABLE 4-2: EXAMPLE OF OUTPUT CODE FOR 18 BITS TABLE 4-3: MINIMUM AND MAXIMUM CODES 4.6 Self-Calibration The device performs a self-calibration of offset and gain for each conversion. This provides reliable conversion results from conversion-to-conversion over variations in temperature as well as power supply fluctuations. 4.7 Input Impedance The MCP3421 uses a switched-capacitor input stage using a 3.2 pF sampling capacitor. This capacitor is switched (charged and discharged) at a rate of the sampling frequency that is generated by the on-board clock. The differential mode impedance varies with the PGA settings. The typical differential input impedance during a normal mode operation is given by: Since the sampling capacitor is only switching to the input pins during a conversion process, the above input impedance is only valid during conversion periods. In a low power standby mode, the above impedance is not presented at the input pins. Therefore, only a leakage current due to ESD diode is presented at the input pins. The conversion accuracy can be affected by the input signal source impedance when any external circuit is connected to the input pins. The source impedance adds to the internal impedance and directly affects the time required to charge the internal sampling capacitor. Therefore, a large input source impedance connected to the input pins can increase the system performance errors such as offset, gain, and integral nonlinearity (INL) errors. Ideally, the input source impedance should be zero. This can be achievable by using an operational amplifier with a closed-loop output impedance of tens of ohms.

DS22003B-page 9 MCP3421 4.8 Aliasing and Anti-aliasing Filter Aliasing occurs when the input signal contains timevarying signal components with frequency greater than half the sample rate. In the aliasing conditions, the device can output unexpected output codes. For applications that are operating in electrical noise environments, the time-varying signal noise or high frequency interference components can be easily added to the input signals and cause aliasing. Although the MCP3421 device has an internal first order sinc filter, its’ filter response may not give enough attenuation to all aliasing signal components. To avoid the aliasing, an external anti-aliasing filter, which can be accomplished with a simple RC low-pass filter, is typically used at the input pins. The low-pass filter cuts off the high frequency noise components and provides a band-limited input signal to the MCP3421 input pins. MCP3421 DS22003B-page 10 © 2006 Microchip Technology Inc. 5.0 USING THE MCP3421 DEVICE 5.1 Operating Modes The user operates the device by setting up the device configuration register and reads the conversion data using serial I2C interface commands. The MCP3421 operates in two modes: (a) Continuous Conversion Mode or (b) One-Shot Conversion Mode (single conversion). The selection is made by setting the O/C bit in the Configuration Register. Refer to Section 5.2 “Configuration Register” for more information. 5.1.1 CONTINUOUS CONVERSION MODE (O/C BIT = 1) The MCP3421 device performs a Continuous Conversion if the O/C bit is set to logic “high”. Once the conversion is completed, the result is placed at the output data register. The device immediately begins another conversion and overwrites the output data register with the most recent data. The device also clears the data ready flag (RDY bit = 0) when the conversion is completed. The device sets the ready flag bit (RDY bit = 1), if the latest conversion result has been read by the Master. 5.1.2 ONE-SHOT CONVERSION MODE (O/C BIT = 0) Once the One-Shot Conversion (single conversion) Mode is selected, the device performs a conversion, updates the Output Data register, clears the data ready flag (RDY = 0), and then enters a low power standby mode. A new One-Shot Conversion is started again when the device receives a new write command with RDY = 1. This One-Shot Conversion Mode is recommended for low power operating applications. During the low current standby mode, the device consumes less than 1 μA typical. For example, if user collects 18 bit conversion data once a second in One-Shot Conversion mode, the device draws only about one fourth of its total operating current. In this example, the device consumes approximately 39 μA (= ~145 μA/3.75 SPS), if the device performs only one conversion per second (1 SPS) in 18-bit conversion mode with 3V power supply. © 2006 Microchip Technology Inc. DS22003B-page 11 MCP3421 5.2 Configuration Register The MCP3421 has an 8-bit wide configuration register to select for: PGA gain, conversion rate, and conversion mode. This register allows the user to change the operating condition of the device and check the status of the device operation. The user can rewrite the configuration byte any time during the device operation. Register 5-1 shows the configuration register bits. REGISTER 5-1: CONFIGURATION REGISTER R/W-1 R/W-0 R/W-0 R/W-1 R/W-0 R/W-0 R/W-0 R/W-0 RDY C1 C0 O/C S1 S0 G1 G0 1 * 0 * 0 * 1 * 0 * 0 * 0 * 0 * bit 7 bit 0 * Default Configuration after Power-On Reset Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 7 RDY: Ready Bit This bit is the data ready flag. In read mode, this bit indicates if the output register has been updated with a new conversion. In One-Shot Conversion mode, writing this bit to “1” initiates a new conversion. Reading RDY bit with the read command: 1 = Output register has not been updated. 0 = Output register has been updated with the latest conversion data. Writing RDY bit with the write command: Continuous Conversion mode: No effect One-Shot Conversion mode: 1 = Initiate a new conversion. 0 = No effect. bit 6-5 C1-C0: Channel Selection Bits These are the Channel Selection bits, but not used in the MCP3421 device. bit 4 O/C: Conversion Mode Bit 1 = Continuous Conversion Mode. Once this bit is selected, the device performs data conversions continuously. 0 = One-Shot Conversion Mode. The device performs a single conversion and enters a low power standby mode until it receives another write/read command. bit 3-2 S1-S0: Sample Rate Selection Bit 00 = 240 SPS (12 bits), 01 = 60 SPS (14 bits), 10 = 15 SPS (16 bits), 11 = 3.75 SPS (18 bits) bit 1-0 G1-G0: PGA Gain Selector Bits 00 = 1 V/V, 01 = 2 V/V, 10 = 4 V/V, 11 = 8 V/V MCP3421 DS22003B-page 12 © 2006 Microchip Technology Inc. In read mode, the RDY bit in the configuration byte indicates the state of the conversion: (a) RDY = 1 indicates that the data bytes that have just been read were not updated from the previous conversion. (b) RDY = 0 indicates that the data bytes that have just been read were updated. If the configuration byte is read repeatedly by clocking continuously after the first read (i.e., after the 5th byte in the 18-bit conversion mode), the state of the RDY bit indicates whether the device is ready with new conversion data. See Figure 5-2. For example, RDY = 0 means new conversion data is ready for reading. In this case, the user can send a stop bit to exit the current read operation and send a new read command to read out updated conversion data. See Figures 5-2 and 5-3 for reading conversion data. The user can rewrite the configuration byte any time for a new setting. Tables 5-1 and 5-2 show the examples of the configuration bit operation. 5.3 I2C Serial Communications The MCP3421 device communicates with Master (microcontroller) through a serial I2C (Inter-Integrated Circuit) interface and supports standard (100 kbits/sec), fast (400 kbits/sec) and high-speed (3.4 Mbits/sec) modes. The serial I2C is a bidirectional 2-wire data bus communication protocol using opendrain SCL and SDA lines. The MCP3421 can only be addressed as a slave. Once addressed, it can receive configuration bits or transmit the latest conversion results. The serial clock pin (SCL) is an input only and the serial data pin (SDA) is bidirectional. An example of a hardware connection diagram is shown in Figure 6-1. The Master starts communication by sending a START bit and terminates the communication by sending a STOP bit. The first byte after the START bit is always the address byte of the device, which includes the device code, the address bits, and the R/W bit. The device code for the MCP3421 device is 1101. The address bits (A2, A1, A0) are pre-programmed at the factory. In general, the address bits are specified by the customer when they order the device. The three address bits are programmed to “000” at the factory, if they are not specified by the customer. Figure 5-1 shows the details of the MCP3421 address byte. During a low power standby mode, SDA and SCL pins remain at a floating condition. More details of the I2C bus characteristic is described in Section 5.6 “I2C Bus Characteristics”. 5.3.1 DEVICE ADDRESSING The address byte is the first byte received following the START condition from the Master device. The MCP3421 device code is 1101. The device code is followed by three address bits (A2, A1, A0) which are programmed at the factory. The three address bits allow up to eight MCP3421 devices on the same data bus line. The (R/W) bit determines if the Master device wants to read the conversion data or write to the Configuration register. If the (R/W) bit is set (read mode), the MCP3421 outputs the conversion data in the following clocks. If the (R/W) bit is cleared (write mode), the MCP3421 expects a configuration byte in the following clocks. When the MCP3421 receives the correct address byte, it outputs an acknowledge bit after the R/W bit. Figure 5-1 shows the MCP3421 address byte. See Figures 5-2 and 5-3 for the read and write operations of the device.

The RDY bit stays high. 1 1 0 New conversion data in Continuous Conversion mode has been just read. The RDY bit changes to high after this read. 1 1 1 The conversion data in Continuous Conversion mode was already read. The latest conversion data is not ready. The RDY bit stays high until a new conversion is completed. © 2006 Microchip Technology Inc. DS22003B-page 13 MCP3421 FIGURE 5-1: MCP3421 Address Byte. 5.3.2 READING DATA FROM THE DEVICE When the Master sends a read command (R/W = 1), the MCP3421 outputs the conversion data bytes and configuration byte. Each byte consists of 8 bits with one acknowledge (ACK) bit. The ACK bit after the address byte is issued by the MCP3421 and the ACK bits after each conversion data bytes are issued by the Master. When the device is configured for 18-bit conversion mode, the device outputs three data bytes followed by a configuration byte. The first 7 data bits in the first data byte are the MSB of the conversion data. The user can ignore the first 6 data bits, and take the 7th data bit (D17) as the MSB of the conversion data. The LSB of the 3rd data byte is the LSB of the conversion data (D0). If the device is configured for 12, 14, or 16 bit-mode, the device outputs two data bytes followed by a configuration byte. In 16 bit-conversion mode, the MSB of the first data byte is the MSB (D15) of the conversion data. In 14-bit conversion mode, the first two bits in the first data byte can be ignored (they are the MSB of the conversion data), and the 3rd bit (D13) is the MSB of the conversion data. In 12-bit conversion mode, the first four bits can be ignored (they are the MSB of the conversion data), and the 5th bit (D11) of the byte represents the MSB of the conversion data. Table 5-3 shows an example of the conversion data output of each conversion mode. The configuration byte follows the output data byte. The device outputs the configuration byte as long as the SCL pulses are received. The device terminates the current outputs when it receives a Not-Acknowledge (NAK), a repeated start or a stop bit at any time during the output bit stream. It is not required to read the configuration byte. However, the user may read the configuration byte to check the RDY bit condition to confirm whether the just received data bytes are updated conversion data. The user may continuously send clock (SCL) to repeatedly read the configuration bytes to check the RDY bit status. Figures 5-2 and 5-3 show the timing diagrams of the reading. 5.3.3 WRITING A CONFIGURATION BYTE TO THE DEVICE When the Master sends an address byte with the R/W bit low (R/W = 0), the MCP3421 expects one configuration byte following the address. Any byte sent after this second byte will be ignored. The user can change the operating mode of the device by writing the configuration register bits. If the device receives a write command with a new configuration setting, the device immediately begins a new conversion and updates the conversion data.

The meaning of the general call address is always specified in the second byte. Refer to Figure 5-5. The MCP3421 supports the following general calls: 5.4.1 GENERAL CALL RESET The general call reset occurs if the second byte is ‘00000110’ (06h). At the acknowledgement of this byte, the device will abort current conversion and perform an internal reset similar to a power-on-reset (POR). 5.4.2 GENERAL CALL CONVERSION The general call conversion occurs if the second byte is ‘00001000’ (08h). All devices on the bus initiate a conversion simultaneously. For the MCP3421 device, the configuration will be set to the One-Shot Conversion mode and a single conversion will be performed. The PGA and data rate settings are unchanged with this general call. FIGURE 5-5: General Call Address Format.

DS22003B-page 17 MCP3421 5.5 High-Speed (HS) Mode The I2C specification requires that a high-speed mode device must be ‘activated’ to operate in high-speed mode. This is done by sending a special address byte of 00001XXX following the START bit. The XXX bits are unique to the High-Speed (HS) mode Master. This byte is referred to as the High-Speed (HS) Master Mode Code (HSMMC). The MCP3421 device does not acknowledge this byte. However, upon receiving this code, the MCP3421 switches on its HS mode filters and communicates up to 3.4 MHz on SDA and SCL. The device will switch out of the HS mode on the next STOP condition. For more information on the HS mode, or other I2C modes, please refer to the Phillips I2C specification. 5.6 I2C Bus Characteristics The I2C specification defines the following bus protocol: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is HIGH. Changes in the data line while the clock line is HIGH will be interpreted as a START or STOP condition. Accordingly, the following bus conditions have been defined using Figure 5-6. 5.6.1 BUS NOT BUSY (A) Both data and clock lines remain HIGH. 5.6.2 START DATA TRANSFER (B) A HIGH to LOW transition of the SDA line while the clock (SCL) is HIGH determines a START condition. All commands must be preceded by a START condition. 5.6.3 STOP DATA TRANSFER (C) A LOW to HIGH transition of the SDA line while the clock (SCL) is HIGH determines a STOP condition. All operations can be ended with a STOP condition. 5.6.4 DATA VALID (D) The state of the data line represents valid data when, after a START condition, the data line is stable for the duration of the HIGH period of the clock signal. The data on the line must be changed during the LOW period of the clock signal. There is one clock pulse per bit of data. Each data transfer is initiated with a START condition and terminated with a STOP condition. 5.6.5 ACKNOWLEDGE The Master (microcontroller) and the slave (MCP3421) use an acknowledge pulse as a hand shake of communication for each byte. The ninth clock pulse of each byte is used for the acknowledgement. The acknowledgement is achieved by pulling-down the SDA line “LOW” during the 9th clock pulse. The clock pulse is always provided by the Master (microcontroller) and the acknowledgement is issued by the receiving device of the byte (Note: The transmitting device must release the SDA line (“HIGH”) during the acknowledge pulse.). For example, the slave (MCP3421) issues the acknowledgement (bring down the SDA line “LOW”) after the end of each receiving byte, and the master (microcontroller) issues the acknowledgement when it reads data from the Slave (MCP3421). When the MCP3421 is addressed, it generates an acknowledge after receiving each byte successfully. The Master device (microcontroller) must provide an extra clock pulse (9th pulse of each byte) for the acknowledgement from the MCP3421 (slave). The MCP3421 (slave) pulls-down the SDA line during the acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the acknowledge clock pulse. During reads, the Master (microcontroller) can terminate the current read operation by not providing an acknowledge bit on the last byte that has been clocked out from the MCP3421. In this case, the MCP3421 releases the SDA line to allow the master (microcontroller) to generate a STOP or repeated START condition. FIGURE 5-6: Data Transfer Sequence on the Serial Bus.

DS22003B-page 21 MCP3421 6.0 BASIC APPLICATION CONFIGURATION The MCP3421 device can be used for various precision analog-to-digital converter applications. The device operates with very simple connections to the application circuit. The following sections discuss the examples of the device connections and applications. 6.1 Connecting to the Application Circuits 6.1.1 INPUT VOLTAGE RANGE The fully differential input signals can be connected to the VIN+ and VIN- input pins. The input range should be within absolute common mode input voltage range: VSS - 0.3V to VDD + 0.3V. Outside this limit, the ESD protection diode at the input pin begins to conduct and the error due to input leakage current increases rapidly. Within this limit, the differential input VIN (= VIN+ - VIN-) is boosted by the PGA before a conversion takes place. The MCP3421 can not accept negative input voltages on the input pins. Figures 6-1 and 6-2 show typical connection examples for differential inputs and a singleended input, respectively. For the single-ended input, the input signal is applied to one of the input pins (typically connected to the VIN+ pin) while the other input pin (typically VIN- pin) is grounded. The input signal range of the single-ended configuration is from 0V to 2.048V. All device characteristics hold for the single-ended configuration, but this configuration loses one bit resolution because the input can only stand in positive half scale. Refer to Section 1.0 “Electrical Characteristics”. 6.1.2 BYPASS CAPACITORS ON VDD PIN For accurate measurement, the application circuit needs a clean supply voltage and must block any noise signal to the MCP3421 device. Figure 6-1 shows an example of using two bypass capacitors (a 10 μF tantalum capacitor and a 0.1 μF ceramic capacitor) in parallel on the VDD line. These capacitors are helpful to filter out any high frequency noises on the VDD line and also provide the momentary bursts of extra currents when the device needs from the supply. These capacitors should be placed as close to the VDD pin as possible (within one inch). If the application circuit has separate digital and analog power supplies, the VDD and VSS of the MCP3421 should reside on the analog plane. 6.1.3 CONNECTING TO I2C BUS USING PULL-UP RESISTORS The SCL and SDA pins of the MCP3421 are open-drain configurations. These pins require a pull-up resistor as shown in Figure 6-1. The value of these pull-up resistors depends on the operating speed (standard, fast, and high speed) and loading capacitance of the I2C bus line. Higher value of pull-up resistor consumes less power, but increases the signal transition time (higher RC time constant) on the bus. Therefore, it can limit the bus operating speed. The lower value of resistor, on the other hand, consumes higher power, but allows higher operating speed. If the bus line has higher capacitance due to long bus line or high number of devices connected to the bus, a smaller pull-up resistor is needed to compensate the long RC time constant. The pull-up resistor is typically chosen between 1 kΩ and 10 kΩ ranges for standard and fast modes, and less than 1 kΩ for high speed mode in high loading capacitance environments. FIGURE 6-1: Typical Connection Example for Differential Inputs. FIGURE 6-2: Typical Connection Example for Single-Ended Input. The number of devices connected to the bus is limited only by the maximum bus capacitance of 400 pF. The bus loading capacitance affects on the bus operating speed. For example, the highest bus operating speed for the 400 pF bus capacitance is 1.7 MHz, and 3.4 MHz for 100 pF. Figure 6-3 shows an example of multiple device connections.

FIGURE 6-3: Example of Multiple Device Connection on I2C Bus. 6.2 Device Connection Test The user can test the presence of the MCP3421 on the I2C bus line without performing an input data conversion. This test can be achieved by checking an acknowledge response from the MCP3421 after sending a read or write command. Here is an example using Figure 6-4: (a) Set the R/W bit “HIGH” in the address byte. (b) The MCP3421 will then acknowledge by pulling SDA bus LOW during the ACK clock and then release the bus back to the I2C Master. (c) A STOP or repeated START bit can then be issued from the Master and I2C communication can continue. FIGURE 6-4: I2C Bus Connection Test. 6.3 Application Examples The MCP3421 device can be used in a broad range of sensor and data acquisition applications. Figure 6-5, shows an example of interfacing with a bridge sensor for pressure measurement. FIGURE 6-5: Example of Pressure Measurement. In this circuit example, the sensor full scale range is ±7.5 mV with a common mode input voltage of VDD / 2. This configuration will provide a full 14-bit resolution across the sensor output range. The alternative circuit for this amount of accuracy would involve an analog gain stage prior to a 16-bit ADC. Figure 6-6 shows an example of temperature measurement using a thermistor. This example can achieve a linear response over a 50°C temperature range. This can be implemented using a standard resistor with 1% tolerance in series with the thermistor. The value of the resistor is selected to be equal to the thermistor value at the mid-point of the desired temperature range. FIGURE 6-6: Example of Temperature Measurement.

Package Types Description The MCP3421 is a single channel low-noise, high accuracy ΔΣ A/D converter with differential inputs and up to 18 bits of resolution in a small SOT-23-6 package. The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially (Δ voltage = 4.096V). The device uses a two-wire I2C compatible serial interface and operates from a single 2.7V to 5.5V power supply. The MCP3421 device performs conversion at rates of 3.75, 15, 60, or 240 samples per second (SPS) depending on the user controllable configuration bit settings using the two-wire I2C serial interface. This device has an on-board programmable gain amplifier (PGA). The user can select the PGA gain of x1, x2, x4, or x8 before the analog-to-digital conversion takes place. This allows the MCP3421 device to convert a smaller input signal with high resolution. The device has two conversion modes: (a) Continuous mode and (b) One-Shot mode. In One-Shot mode, the device enters a low current standby mode automatically after one conversion. This reduces current consumption greatly during idle periods. The MCP3421 device can be used for various high accuracy analog-to-digital data conversion applications where design simplicity, low power, and small footprint are major considerations.

The MCP3421 device accepts a fully differential analog input signal which is connected on the VIN+ and VINinput pins. The differential voltage that is converted is defined by VIN = (VIN+ - VIN-) where VIN+ is the voltage applied at the VIN+ pin and VIN- is the voltage applied at the VIN- pin. The input signal level is amplified by the programmable gain amplifier (PGA) before the conversion. The differential input voltage should not exceed an absolute of (2* VREF/PGA) for accurate measurement, where VREF is the internal reference voltage (2.048V) and PGA is the PGA gain setting. The converter output code will saturate if the input range exceeds (2* VREF/PGA). The absolute voltage range on each of the differential input pins is from VSS-0.3V to VDD+0.3V. Any voltage above or below this range will cause leakage currents through the Electrostatic Discharge (ESD) diodes at the input pins. This ESD current can cause unexpected performance of the device. The common mode of the analog inputs should be chosen such that both the differential analog input range and the absolute voltage range on each pin are within the specified operating range defined in Section 1.0 “Electrical Characteristics” and Section 4.0 “Description of Device Operation”. 3.2 Supply Voltage (VDD, VSS) VDD is the power supply pin for the device. This pin requires an appropriate bypass capacitor of about 0.1 μF (ceramic) to ground. An additional 10 μF capacitor (tantalum) in parallel is also recommended to further attenuate high frequency noise present in some application boards. The supply voltage (VDD) must be maintained in the 2.7V to 5.5V range for specified operation. VSS is the ground pin and the current return path of the device. The user must connect the VSS pin to a ground plane through a low impedance connection. If an analog ground path is available in the application PCB (printed circuit board), it is highly recommended that the VSS pin be tied to the analog ground path or isolated within an analog ground plane of the circuit board. 3.3 Serial Clock Pin (SCL) SCL is the serial clock pin of the I2C interface. The MCP3421 acts only as a slave and the SCL pin accepts only external serial clocks. The input data from the Master device is shifted into the SDA pin on the rising edges of the SCL clock and output from the MCP3421 occurs at the falling edges of the SCL clock. The SCL pin is an open-drain N-channel driver. Therefore, it needs a pull-up resistor from the VDD line to the SCL pin. Refer to Section 5.3 “I2C Serial Communications” for more details of I2C Serial Interface communication. 3.4 Serial Data Pin (SDA) SDA is the serial data pin of the I2C interface. The SDA pin is used for input and output data. In read mode, the conversion result is read from the SDA pin (output). In write mode, the device configuration bits are written (input) though the SDA pin. The SDA pin is an opendrain N-channel driver. Therefore, it needs a pull-up resistor from the VDD line to the SDA pin. Except for start and stop conditions, the data on the SDA pin must be stable during the high period of the clock. The high or low state of the SDA pin can only change when the clock signal on the SCL pin is low. Refer to Section 5.3 “I2C Serial Communications” for more details of I2C Serial Interface communication.

DS22003B-page 7 MCP3421 4.0 DESCRIPTION OF DEVICE OPERATION 4.1 General Overview The MCP3421 is a low-power, 18-Bit Delta-Sigma A/D converter with an I2C serial interface. The device contains an on-board voltage reference (2.048V), programmable gain amplifier (PGA), and internal oscillator. The user can select 12, 14, 16, or 18 bit conversion by setting the configuration register bits. The device can be operated in Continuous Conversion or One-Shot Conversion mode. In the Continuous Conversion mode, the device converts the inputs continuously. While in the One-Shot Conversion mode, the device converts the input one time and stays in the low-power standby mode until it receives another command for a new conversion. During the standby mode, the device consumes less than 0.1 μA typical. 4.2 Power-On-Reset (POR) The device contains an internal Power-On-Reset (POR) circuit that monitors power supply voltage (VDD) during operation. This circuit ensures correct device start-up at system power-up and power-down events. The POR has built-in hysteresis and a timer to give a high degree of immunity to potential ripples and noises on the power supply. A 0.1 μF decoupling capacitor should be mounted as close as possible to the VDD pin for additional transient immunity. The threshold voltage is set at 2.2V with a tolerance of approximately ±5%. If the supply voltage falls below this threshold, the device will be held in a reset condition. The typical hysteresis value is approximately 200 mV. The POR circuit is shut-down during the low-power standby mode. Once a power-up event has occurred, the device requires additional delay time (approximately 300 μs) before a conversion can take place. During this time, all internal analog circuitries are settled before the first conversion occurs. Figure 4-1 illustrates the conditions for power-up and power-down events under typical start-up conditions. When the device powers up, it automatically resets and sets the configuration bits to default settings. The default configuration bit conditions are a PGA gain of 1 V/V and a conversion speed of 240 SPS in Continuous Conversion mode. When the device receives an I2C General Call Reset command, it performs an internal reset similar to a Power-On-Reset event. FIGURE 4-1: POR Operation. 4.3 Internal Voltage Reference The device contains an on-board 2.048V voltage reference. This reference voltage is for internal use only and not directly measurable. The specifications of the reference voltage are part of the device’s gain and drift specifications. Therefore, there is no separate specification for the on-board reference. 4.4 Analog Input Channel The differential analog input channel has a switched capacitor structure. The internal sampling capacitor (3.2 pF) is charged and discharged to process a conversion. The charging and discharging of the input sampling capacitor creates dynamic input currents at the VIN+ and VIN- input pins, which is inversely proportional to the internal sampling capacitor and internal frequency. The current is also a function of the differential input voltages. Care must be taken in setting the common-mode voltage and input voltage ranges so that the input limits do not exceed the ranges specified in Section 1.0 “Electrical Characteristics”. 4.5 Digital Output Code The digital output code produced by the MCP3421 is a function of PGA gain, input signal, and internal reference voltage. In a fixed setting, the digital output code is proportional to the voltage difference between the two analog inputs. The output data format is a binary two’s complement. With this code scheme, the MSB can be considered a sign indicator. When the MSB is a logic ‘0’, it indicates a positive value. When the MSB is a logic ‘1’, it indicates a negative value. The following is an example of the output code: (a) for a negative full-scale input voltage: 100...000 (b) for a zero differential input voltage: 000...000 (c) for a positive full-scale input voltage: 011...111. The MSB is always transmitted first through the serial port. The number of data bits for each conversion is 18, 16, 14, or 12 bits depending on the conversion mode selection. VDD 2.2V 2.0V 300 μS Reset Start-up Normal Operation Reset Time MCP3421 DS22003B-page 8 © 2006 Microchip Technology Inc. The output codes will not roll-over if the input voltage exceeds the maximum input range. In this case, the code will be locked at 0111...11 for all voltages greater than +(VREF - 1 LSB) and 1000...00 for voltages less than -VREF. Table 4-2 shows an example of output codes of various input levels using 18 bit conversion mode. Table 4-3 shows an example of minimum and maximum codes for each data rate option. The output code is given by: EQUATION 4-1: The LSB of the code is given by: EQUATION 4-2: TABLE 4-1: LSB SIZE OF VARIOUS BIT CONVERSION MODES TABLE 4-2: EXAMPLE OF OUTPUT CODE FOR 18 BITS TABLE 4-3: MINIMUM AND MAXIMUM CODES 4.6 Self-Calibration The device performs a self-calibration of offset and gain for each conversion. This provides reliable conversion results from conversion-to-conversion over variations in temperature as well as power supply fluctuations. 4.7 Input Impedance The MCP3421 uses a switched-capacitor input stage using a 3.2 pF sampling capacitor. This capacitor is switched (charged and discharged) at a rate of the sampling frequency that is generated by the on-board clock. The differential mode impedance varies with the PGA settings. The typical differential input impedance during a normal mode operation is given by: Since the sampling capacitor is only switching to the input pins during a conversion process, the above input impedance is only valid during conversion periods. In a low power standby mode, the above impedance is not presented at the input pins. Therefore, only a leakage current due to ESD diode is presented at the input pins. The conversion accuracy can be affected by the input signal source impedance when any external circuit is connected to the input pins. The source impedance adds to the internal impedance and directly affects the time required to charge the internal sampling capacitor. Therefore, a large input source impedance connected to the input pins can increase the system performance errors such as offset, gain, and integral nonlinearity (INL) errors. Ideally, the input source impedance should be zero. This can be achievable by using an operational amplifier with a closed-loop output impedance of tens of ohms.

DS22003B-page 9 MCP3421 4.8 Aliasing and Anti-aliasing Filter Aliasing occurs when the input signal contains timevarying signal components with frequency greater than half the sample rate. In the aliasing conditions, the device can output unexpected output codes. For applications that are operating in electrical noise environments, the time-varying signal noise or high frequency interference components can be easily added to the input signals and cause aliasing. Although the MCP3421 device has an internal first order sinc filter, its’ filter response may not give enough attenuation to all aliasing signal components. To avoid the aliasing, an external anti-aliasing filter, which can be accomplished with a simple RC low-pass filter, is typically used at the input pins. The low-pass filter cuts off the high frequency noise components and provides a band-limited input signal to the MCP3421 input pins. MCP3421 DS22003B-page 10 © 2006 Microchip Technology Inc. 5.0 USING THE MCP3421 DEVICE 5.1 Operating Modes The user operates the device by setting up the device configuration register and reads the conversion data using serial I2C interface commands. The MCP3421 operates in two modes: (a) Continuous Conversion Mode or (b) One-Shot Conversion Mode (single conversion). The selection is made by setting the O/C bit in the Configuration Register. Refer to Section 5.2 “Configuration Register” for more information. 5.1.1 CONTINUOUS CONVERSION MODE (O/C BIT = 1) The MCP3421 device performs a Continuous Conversion if the O/C bit is set to logic “high”. Once the conversion is completed, the result is placed at the output data register. The device immediately begins another conversion and overwrites the output data register with the most recent data. The device also clears the data ready flag (RDY bit = 0) when the conversion is completed. The device sets the ready flag bit (RDY bit = 1), if the latest conversion result has been read by the Master. 5.1.2 ONE-SHOT CONVERSION MODE (O/C BIT = 0) Once the One-Shot Conversion (single conversion) Mode is selected, the device performs a conversion, updates the Output Data register, clears the data ready flag (RDY = 0), and then enters a low power standby mode. A new One-Shot Conversion is started again when the device receives a new write command with RDY = 1. This One-Shot Conversion Mode is recommended for low power operating applications. During the low current standby mode, the device consumes less than 1 μA typical. For example, if user collects 18 bit conversion data once a second in One-Shot Conversion mode, the device draws only about one fourth of its total operating current. In this example, the device consumes approximately 39 μA (= ~145 μA/3.75 SPS), if the device performs only one conversion per second (1 SPS) in 18-bit conversion mode with 3V power supply. © 2006 Microchip Technology Inc. DS22003B-page 11 MCP3421 5.2 Configuration Register The MCP3421 has an 8-bit wide configuration register to select for: PGA gain, conversion rate, and conversion mode. This register allows the user to change the operating condition of the device and check the status of the device operation. The user can rewrite the configuration byte any time during the device operation. Register 5-1 shows the configuration register bits. REGISTER 5-1: CONFIGURATION REGISTER R/W-1 R/W-0 R/W-0 R/W-1 R/W-0 R/W-0 R/W-0 R/W-0 RDY C1 C0 O/C S1 S0 G1 G0 1 * 0 * 0 * 1 * 0 * 0 * 0 * 0 * bit 7 bit 0 * Default Configuration after Power-On Reset Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 7 RDY: Ready Bit This bit is the data ready flag. In read mode, this bit indicates if the output register has been updated with a new conversion. In One-Shot Conversion mode, writing this bit to “1” initiates a new conversion. Reading RDY bit with the read command: 1 = Output register has not been updated. 0 = Output register has been updated with the latest conversion data. Writing RDY bit with the write command: Continuous Conversion mode: No effect One-Shot Conversion mode: 1 = Initiate a new conversion. 0 = No effect. bit 6-5 C1-C0: Channel Selection Bits These are the Channel Selection bits, but not used in the MCP3421 device. bit 4 O/C: Conversion Mode Bit 1 = Continuous Conversion Mode. Once this bit is selected, the device performs data conversions continuously. 0 = One-Shot Conversion Mode. The device performs a single conversion and enters a low power standby mode until it receives another write/read command. bit 3-2 S1-S0: Sample Rate Selection Bit 00 = 240 SPS (12 bits), 01 = 60 SPS (14 bits), 10 = 15 SPS (16 bits), 11 = 3.75 SPS (18 bits) bit 1-0 G1-G0: PGA Gain Selector Bits 00 = 1 V/V, 01 = 2 V/V, 10 = 4 V/V, 11 = 8 V/V MCP3421 DS22003B-page 12 © 2006 Microchip Technology Inc. In read mode, the RDY bit in the configuration byte indicates the state of the conversion: (a) RDY = 1 indicates that the data bytes that have just been read were not updated from the previous conversion. (b) RDY = 0 indicates that the data bytes that have just been read were updated. If the configuration byte is read repeatedly by clocking continuously after the first read (i.e., after the 5th byte in the 18-bit conversion mode), the state of the RDY bit indicates whether the device is ready with new conversion data. See Figure 5-2. For example, RDY = 0 means new conversion data is ready for reading. In this case, the user can send a stop bit to exit the current read operation and send a new read command to read out updated conversion data. See Figures 5-2 and 5-3 for reading conversion data. The user can rewrite the configuration byte any time for a new setting. Tables 5-1 and 5-2 show the examples of the configuration bit operation. 5.3 I2C Serial Communications The MCP3421 device communicates with Master (microcontroller) through a serial I2C (Inter-Integrated Circuit) interface and supports standard (100 kbits/sec), fast (400 kbits/sec) and high-speed (3.4 Mbits/sec) modes. The serial I2C is a bidirectional 2-wire data bus communication protocol using opendrain SCL and SDA lines. The MCP3421 can only be addressed as a slave. Once addressed, it can receive configuration bits or transmit the latest conversion results. The serial clock pin (SCL) is an input only and the serial data pin (SDA) is bidirectional. An example of a hardware connection diagram is shown in Figure 6-1. The Master starts communication by sending a START bit and terminates the communication by sending a STOP bit. The first byte after the START bit is always the address byte of the device, which includes the device code, the address bits, and the R/W bit. The device code for the MCP3421 device is 1101. The address bits (A2, A1, A0) are pre-programmed at the factory. In general, the address bits are specified by the customer when they order the device. The three address bits are programmed to “000” at the factory, if they are not specified by the customer. Figure 5-1 shows the details of the MCP3421 address byte. During a low power standby mode, SDA and SCL pins remain at a floating condition. More details of the I2C bus characteristic is described in Section 5.6 “I2C Bus Characteristics”. 5.3.1 DEVICE ADDRESSING The address byte is the first byte received following the START condition from the Master device. The MCP3421 device code is 1101. The device code is followed by three address bits (A2, A1, A0) which are programmed at the factory. The three address bits allow up to eight MCP3421 devices on the same data bus line. The (R/W) bit determines if the Master device wants to read the conversion data or write to the Configuration register. If the (R/W) bit is set (read mode), the MCP3421 outputs the conversion data in the following clocks. If the (R/W) bit is cleared (write mode), the MCP3421 expects a configuration byte in the following clocks. When the MCP3421 receives the correct address byte, it outputs an acknowledge bit after the R/W bit. Figure 5-1 shows the MCP3421 address byte. See Figures 5-2 and 5-3 for the read and write operations of the device.

DS22003B-page 13 MCP3421 FIGURE 5-1: MCP3421 Address Byte. 5.3.2 READING DATA FROM THE DEVICE When the Master sends a read command (R/W = 1), the MCP3421 outputs the conversion data bytes and configuration byte. Each byte consists of 8 bits with one acknowledge (ACK) bit. The ACK bit after the address byte is issued by the MCP3421 and the ACK bits after each conversion data bytes are issued by the Master. When the device is configured for 18-bit conversion mode, the device outputs three data bytes followed by a configuration byte. The first 7 data bits in the first data byte are the MSB of the conversion data. The user can ignore the first 6 data bits, and take the 7th data bit (D17) as the MSB of the conversion data. The LSB of the 3rd data byte is the LSB of the conversion data (D0). If the device is configured for 12, 14, or 16 bit-mode, the device outputs two data bytes followed by a configuration byte. In 16 bit-conversion mode, the MSB of the first data byte is the MSB (D15) of the conversion data. In 14-bit conversion mode, the first two bits in the first data byte can be ignored (they are the MSB of the conversion data), and the 3rd bit (D13) is the MSB of the conversion data. In 12-bit conversion mode, the first four bits can be ignored (they are the MSB of the conversion data), and the 5th bit (D11) of the byte represents the MSB of the conversion data. Table 5-3 shows an example of the conversion data output of each conversion mode. The configuration byte follows the output data byte. The device outputs the configuration byte as long as the SCL pulses are received. The device terminates the current outputs when it receives a Not-Acknowledge (NAK), a repeated start or a stop bit at any time during the output bit stream. It is not required to read the configuration byte. However, the user may read the configuration byte to check the RDY bit condition to confirm whether the just received data bytes are updated conversion data. The user may continuously send clock (SCL) to repeatedly read the configuration bytes to check the RDY bit status. Figures 5-2 and 5-3 show the timing diagrams of the reading. 5.3.3 WRITING A CONFIGURATION BYTE TO THE DEVICE When the Master sends an address byte with the R/W bit low (R/W = 0), the MCP3421 expects one configuration byte following the address. Any byte sent after this second byte will be ignored. The user can change the operating mode of the device by writing the configuration register bits. If the device receives a write command with a new configuration setting, the device immediately begins a new conversion and updates the conversion data.

The meaning of the general call address is always specified in the second byte. Refer to Figure 5-5. The MCP3421 supports the following general calls: 5.4.1 GENERAL CALL RESET The general call reset occurs if the second byte is ‘00000110’ (06h). At the acknowledgement of this byte, the device will abort current conversion and perform an internal reset similar to a power-on-reset (POR). 5.4.2 GENERAL CALL CONVERSION The general call conversion occurs if the second byte is ‘00001000’ (08h). All devices on the bus initiate a conversion simultaneously. For the MCP3421 device, the configuration will be set to the One-Shot Conversion mode and a single conversion will be performed. The PGA and data rate settings are unchanged with this general call. FIGURE 5-5: General Call Address Format.

DS22003B-page 17 MCP3421 5.5 High-Speed (HS) Mode The I2C specification requires that a high-speed mode device must be ‘activated’ to operate in high-speed mode. This is done by sending a special address byte of 00001XXX following the START bit. The XXX bits are unique to the High-Speed (HS) mode Master. This byte is referred to as the High-Speed (HS) Master Mode Code (HSMMC). The MCP3421 device does not acknowledge this byte. However, upon receiving this code, the MCP3421 switches on its HS mode filters and communicates up to 3.4 MHz on SDA and SCL. The device will switch out of the HS mode on the next STOP condition. For more information on the HS mode, or other I2C modes, please refer to the Phillips I2C specification. 5.6 I2C Bus Characteristics The I2C specification defines the following bus protocol: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is HIGH. Changes in the data line while the clock line is HIGH will be interpreted as a START or STOP condition. Accordingly, the following bus conditions have been defined using Figure 5-6. 5.6.1 BUS NOT BUSY (A) Both data and clock lines remain HIGH. 5.6.2 START DATA TRANSFER (B) A HIGH to LOW transition of the SDA line while the clock (SCL) is HIGH determines a START condition. All commands must be preceded by a START condition. 5.6.3 STOP DATA TRANSFER (C) A LOW to HIGH transition of the SDA line while the clock (SCL) is HIGH determines a STOP condition. All operations can be ended with a STOP condition. 5.6.4 DATA VALID (D) The state of the data line represents valid data when, after a START condition, the data line is stable for the duration of the HIGH period of the clock signal. The data on the line must be changed during the LOW period of the clock signal. There is one clock pulse per bit of data. Each data transfer is initiated with a START condition and terminated with a STOP condition. 5.6.5 ACKNOWLEDGE The Master (microcontroller) and the slave (MCP3421) use an acknowledge pulse as a hand shake of communication for each byte. The ninth clock pulse of each byte is used for the acknowledgement. The acknowledgement is achieved by pulling-down the SDA line “LOW” during the 9th clock pulse. The clock pulse is always provided by the Master (microcontroller) and the acknowledgement is issued by the receiving device of the byte (Note: The transmitting device must release the SDA line (“HIGH”) during the acknowledge pulse.). For example, the slave (MCP3421) issues the acknowledgement (bring down the SDA line “LOW”) after the end of each receiving byte, and the master (microcontroller) issues the acknowledgement when it reads data from the Slave (MCP3421). When the MCP3421 is addressed, it generates an acknowledge after receiving each byte successfully. The Master device (microcontroller) must provide an extra clock pulse (9th pulse of each byte) for the acknowledgement from the MCP3421 (slave). The MCP3421 (slave) pulls-down the SDA line during the acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the acknowledge clock pulse. During reads, the Master (microcontroller) can terminate the current read operation by not providing an acknowledge bit on the last byte that has been clocked out from the MCP3421. In this case, the MCP3421 releases the SDA line to allow the master (microcontroller) to generate a STOP or repeated START condition. FIGURE 5-6: Data Transfer Sequence on the Serial Bus.

DS22003B-page 21 MCP3421 6.0 BASIC APPLICATION CONFIGURATION The MCP3421 device can be used for various precision analog-to-digital converter applications. The device operates with very simple connections to the application circuit. The following sections discuss the examples of the device connections and applications. 6.1 Connecting to the Application Circuits 6.1.1 INPUT VOLTAGE RANGE The fully differential input signals can be connected to the VIN+ and VIN- input pins. The input range should be within absolute common mode input voltage range: VSS - 0.3V to VDD + 0.3V. Outside this limit, the ESD protection diode at the input pin begins to conduct and the error due to input leakage current increases rapidly. Within this limit, the differential input VIN (= VIN+ - VIN-) is boosted by the PGA before a conversion takes place. The MCP3421 can not accept negative input voltages on the input pins. Figures 6-1 and 6-2 show typical connection examples for differential inputs and a singleended input, respectively. For the single-ended input, the input signal is applied to one of the input pins (typically connected to the VIN+ pin) while the other input pin (typically VIN- pin) is grounded. The input signal range of the single-ended configuration is from 0V to 2.048V. All device characteristics hold for the single-ended configuration, but this configuration loses one bit resolution because the input can only stand in positive half scale. Refer to Section 1.0 “Electrical Characteristics”. 6.1.2 BYPASS CAPACITORS ON VDD PIN For accurate measurement, the application circuit needs a clean supply voltage and must block any noise signal to the MCP3421 device. Figure 6-1 shows an example of using two bypass capacitors (a 10 μF tantalum capacitor and a 0.1 μF ceramic capacitor) in parallel on the VDD line. These capacitors are helpful to filter out any high frequency noises on the VDD line and also provide the momentary bursts of extra currents when the device needs from the supply. These capacitors should be placed as close to the VDD pin as possible (within one inch). If the application circuit has separate digital and analog power supplies, the VDD and VSS of the MCP3421 should reside on the analog plane. 6.1.3 CONNECTING TO I2C BUS USING PULL-UP RESISTORS The SCL and SDA pins of the MCP3421 are open-drain configurations. These pins require a pull-up resistor as shown in Figure 6-1. The value of these pull-up resistors depends on the operating speed (standard, fast, and high speed) and loading capacitance of the I2C bus line. Higher value of pull-up resistor consumes less power, but increases the signal transition time (higher RC time constant) on the bus. Therefore, it can limit the bus operating speed. The lower value of resistor, on the other hand, consumes higher power, but allows higher operating speed. If the bus line has higher capacitance due to long bus line or high number of devices connected to the bus, a smaller pull-up resistor is needed to compensate the long RC time constant. The pull-up resistor is typically chosen between 1 kΩ and 10 kΩ ranges for standard and fast modes, and less than 1 kΩ for high speed mode in high loading capacitance environments. FIGURE 6-1: Typical Connection Example for Differential Inputs. FIGURE 6-2: Typical Connection Example for Single-Ended Input. The number of devices connected to the bus is limited only by the maximum bus capacitance of 400 pF. The bus loading capacitance affects on the bus operating speed. For example, the highest bus operating speed for the 400 pF bus capacitance is 1.7 MHz, and 3.4 MHz for 100 pF. Figure 6-3 shows an example of multiple device connections.

FIGURE 6-3: Example of Multiple Device Connection on I2C Bus. 6.2 Device Connection Test The user can test the presence of the MCP3421 on the I2C bus line without performing an input data conversion. This test can be achieved by checking an acknowledge response from the MCP3421 after sending a read or write command. Here is an example using Figure 6-4: (a) Set the R/W bit “HIGH” in the address byte. (b) The MCP3421 will then acknowledge by pulling SDA bus LOW during the ACK clock and then release the bus back to the I2C Master. (c) A STOP or repeated START bit can then be issued from the Master and I2C communication can continue. FIGURE 6-4: I2C Bus Connection Test. 6.3 Application Examples The MCP3421 device can be used in a broad range of sensor and data acquisition applications. Figure 6-5, shows an example of interfacing with a bridge sensor for pressure measurement. FIGURE 6-5: Example of Pressure Measurement. In this circuit example, the sensor full scale range is ±7.5 mV with a common mode input voltage of VDD / 2. This configuration will provide a full 14-bit resolution across the sensor output range. The alternative circuit for this amount of accuracy would involve an analog gain stage prior to a 16-bit ADC. Figure 6-6 shows an example of temperature measurement using a thermistor. This example can achieve a linear response over a 50°C temperature range. This can be implemented using a standard resistor with 1% tolerance in series with the thermistor. The value of the resistor is selected to be equal to the thermistor value at the mid-point of the desired temperature range. FIGURE 6-6: Example of Temperature Measurement.

By executing powerful instructions in a single clock cycle, the ATtiny26(L) achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATtiny26(L) has a high precision ADC with up to 11 single ended channels and 8 differential channels. Seven differential channels have an optional gain of 20x. Four out of the seven differential channels, which have the optional gain, can be used at the same time. The ATtiny26(L) also has a high frequency 8-bit PWM module with two independent outputs. Two of the PWM outputs have inverted non-overlapping output pins ideal for synchronous rectification. The Universal Serial Interface of the ATtiny26(L) allows efficient software implementation of TWI (Two-wire Serial Interface) or SM-bus interface. These features allow for highly integrated battery charger and lighting ballast applications, low-end thermostats, and firedetectors, among other applications. The ATtiny26(L) provides 2K bytes of Flash, 128 bytes EEPROM, 128 bytes SRAM, up to 16 general purpose I/O lines, 32 general purpose working registers, two 8-bit Timer/Counters, one with PWM outputs, internal and external Oscillators, internal and external interrupts, programmable Watchdog Timer, 11-channel, 10-bit Analog to Digital Converter with two differential voltage input gain stages, and four software selectable power saving modes. The Idle mode stops the CPU while allowing the Timer/Counters and interrupt system to continue functioning. The ATtiny26(L) also has a dedicated ADC Noise Reduction mode for reducing the noise in ADC conversion. In this sleep mode, only the ADC is functioning. The Power-down mode saves the register contents but freezes the oscillators, disabling all other chip functions until the next interrupt or hardware reset. The Standby mode is the same as the Power-down mode, but external oscillators are enabled. The wakeup or interrupt on pin change features enable the ATtiny26(L) to be highly responsive to external events, still featuring the lowest power consumption while in the Power-down mode. The device is manufactured using Atmel’s high density non-volatile memory technology. By combining an enhanced RISC 8-bit CPU with Flash on a monolithic chip, the ATtiny26(L) is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. The ATtiny26(L) AVR is supported with a full suite of program and system development tools including: Macro assemblers, program debugger/simulators, In-circuit emulators, and evaluation kits. 4 1477KS–AVR–08/10 ATtiny26(L) Block Diagram Figure 1.

GND Digital ground pin. AVCC AVCC is the supply voltage pin for Port A and the A/D Converter (ADC). It should be externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC through a low-pass filter. See page 94 for details on operating of the ADC. Port A (PA7..PA0) Port A is an 8-bit general purpose I/O port. PA7..PA0 are all I/O pins that can provide internal pull-ups (selected for each bit). Port A has alternate functions as analog inputs for the ADC and analog comparator and pin change interrupt as described in “Alternate Port Functions” on page 46. Port B (PB7..PB0) Port B is an 8-bit general purpose I/O port. PB6..0 are all I/O pins that can provide internal pullups (selected for each bit). PB7 is an I/O pin if not used as the reset. To use pin PB7 as an I/O pin, instead of RESET pin, program (“0”) RSTDISBL Fuse. Port B has alternate functions for the ADC, clocking, timer counters, USI, SPI programming, and pin change interrupt as described in “Alternate Port Functions” on page 46. An External Reset is generated by a low level on the PB7/RESET pin. Reset pulses longer than 50 ns will generate a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a reset. XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit. XTAL2 Output from the inverting oscillator amplifier. 6 1477KS–AVR–08/10 ATtiny26(L) General Information Resources A comprehensive set of development tools, application notes and datasheets are available for download on http://www.atmel.com/avr.

Un design innovant pour une utilisation efficace et confortable Un boîtier léger et compact et une interface utilisateur conviviale Un afficheur d’une dimension et d’une lisibilité inégalées Une calibration 100% numérique pour une précision et un coût maîtrisés Des versions entièrement programmables respectant la norme SCPI Nouvelle technologie d’affichage intelligent (Smart Persistence Oscilloscope) Des atouts qui séduiront l’Enseignement et l’Industrie Si intelligents que vous pouvez les choisir pour leurs courbes ! Série MTX COMPACT « Une gamme complète et performante d’instruments de laboratoire » MTX 3252 MTX 3352 MTX 3354 MTX 3240 MTX 3250 MTX 3250 Multimètre-Analyseur MTX 3240 Générateur BF-Mesureur MTX 3252 - MTX 3352 - MTX 3354 Oscilloscopes-Analyseurs Tout comme le générateur de la même famille, le multimètre MTX est un appareil surdoué, multifonction. Grâce à son analyse du signal il évite à l’utilisateur la mise en oeuvre d’autres instruments (oscilloscope par exemple), pour contrôler la validité des mesures réalisées. Impossible de commettre les, si fréquentes et souvent ignorées, erreurs dues à un facteur de crête trop élevé. En effet, le MTX 3250 mesure en permanence les crêtes rapides à 500 μs et vous alerte en cas d’anomalie. Mieux encore, en validant alors le “Mode AUTO PEAK”, le multimètre commutera automatiquement sur une gamme adaptée à la nature du signal mesuré. L’affichage du facteur de crête vous permettra aussi d’établir un premier diagnostic qualitatif sur vos signaux. Le MTX 3250, c’est encore la rationalisation de l’investissement réalisé, puisqu’il est également fréquencemètre, thermomètre et même enregistreur, vous évitant ainsi l’achat d’un instrument d’usage ponctuel. Ainsi, pour les enregistrements en laboratoire jusqu’à 4 voies et 12 paramètres, la version “acquisition de données” et son logiciel PC associé rendront un service performant à partir d’un instrument polyvalent. La température est directement mesurée à partir de Pt 100 ou Pt 1000, de même que la fréquence, jusqu’à 1 MHz, avec période et rapport cyclique. Et pour mieux répondre à vos attentes dans le cadre de systèmes automatisés, cet instrument existe en version programmable à 100 % via une liaison optique RS232 à 57600 bauds, compatible SCPI.

Pour commander MTX3250 Multimètre de Table 50 000 pts MTX3250-P Multimètre de Table 50 000 pts + RS232 Fourni avec un cordon de liaison optique RS232, un manuel de programmation et les drivers Labwindows / Labview sur CD-Rom. MTX3250-A Multimètre de Table 50 000 pts + Acquisition Fourni avec un cordon de liaison optique RS232, un manuel de programmation, les drivers Labwindows / Labview et le logiciel d’acquisition de données SX-DMM sur CD-Rom. Tout commence avec une connexion réduite à 3 bornes qui limite erreurs et manipulations, permettant un “AUTORANGING” courant complet de 50 μA à 20 A. Le MTX 3250 offre ensuite, grâce à son affichage triple, les combinaisons de mesures qui répondent simplement et efficacement à vos applications courantes, comme, par exemple, la mesure de bande passante (affichage de l’atténuation en dB et de la fréquence). Accessoires et informations pour commander Pour la maîtrise métrologique, le “Mode SPEC” calcule et affiche les incertitudes de l’instrument en fonction des gammes et de la valeur mesurée Le Mode offre la lecture directe de la grandeur mesurée, ainsi que l’unité physique correspondante Le “Mode Surveillance” enregistre les minima et les maxima afin de piéger et de dater vos défauts L’association fonctionnelle Le “Mode RELATIF” exprimé en absolu, pourcentage ou dB (ratio), permet une exploitation directe MTX 3250 : multimètre-analyseur intégré Asservissement et affichage de la fréquence Contrôle et affichage de l’AMPLITUDE VCC (crête/crête) et de l’OFFSET VDC Contrôle et affichage du rapport cyclique Le MTX 3240 c’est aussi la rationalisation de l’investissement réalisé, puisqu’il est aussi un fréquencemètre 100 MHz (Cat. I, 300 V), vous évitant ainsi l’achat d’un instrument d’usage souvent ponctuel. Et pour répondre enfin de manière économique à vos attentes dans le cadre de systèmes automatisés, ce générateur existe en version programmable à 100 % via une liaison rapide, compatible SCPI. Sa technologie permet à chacun de bénéficier de fonctions nouvelles, indispensables : Réglage de la fréquence, garantie stable au digit près, et accélérateur intelligent avec changement de gammes automatique pour la fréquence Changement de gammes automatique optimisé pour l’amplitude “LEVEL et OFFSET” Rapport cyclique réglable sans variation ni division de la fréquence Fonction “LOGIC” pour une réponse simple et rapide à la génération de signaux logiques à seuils directement ajustables Un générateur robuste, avec des sorties protégées 60 VDC / 40 VAC L’association fonctionnelle MTX 3240 : générateur-mesureur autonome Un générateur doté de caractéristiques innovantes LCD 50 x 140 mm 0,1 Hz à 5,1 MHz Sinus, carré, 1) Principale : LIN ou LOG 0,1 Hz à 100 MHz 115 V - 230 V - 170x270x190 mm optique Afficheur principal 7 gammes + triangle, jusqu’à 20 VCC CONTINU, Précision : 0,05 % 240 V Masse : 2,8 kg RS232 20 mm réglage fin au digit impulsion, circuit ouvert, 1 : 50 Min Entrée 300 V, Cat.

Ergonomie La technologie " " permet de faire persister les acquisitions pendant une durée paramétrée pour observer un cumul de traces. L’intensité lumineuse ou la couleur, affectée au point à l’écran, va décroître si celui-ci n’est pas renouvelé lors d’une nouvelle acquisition. L’acquisition se fait donc en trois dimensions : - le temps - l’amplitude - l’occurrence Grâce à sa profondeur mémoire de 50.000 points, l’oscilloscope acquiert et traite l’information en parallèle. Le nombre d’acquisitions à la seconde peut-être multiplié par un facteur supérieur à 1000, ainsi le temps mort entre deux acquisitions est considérablement réduit. Représentation à l’écran des 50.000 points acquis par un système de compression intelligente. L’occurrence apporte une dimension statistique à la répartition des échantillons.

Posés directement sur la paillasse, l’espace libéré devant eux est déjà très appréciable, de plus, leur hauteur est calculée pour pouvoir les glisser sans peine sous les demi-étagères. Leur faible profondeur et leur largeur standard vous permettent aussi de les placer sur ces mêmes demi-étagères ou de les poser sur un autre instrument. Le déplacement et le transport sont très aisés grâce à leur poignée intégrée et à leur légèreté. Une architecture et des formes avantageuses qui vous font gagner de la place Même à distance ou dans des conditions d’éclairage difficiles (soleil, néons), les mesures sont parfaitement lisibles, grâce notamment à un afficheur négatif de grandes dimensions (50 x 140 mm), à un rétro-éclairage à matrice de leds ajustable, ainsi qu’à une hauteur exceptionnelle de 20 mm de l’afficheur principal (MTX 3240 et MTX 3250). Monochrome ou couleur, l’écran LCD réglable et orientable des MTX 3252 et MTX 3352 vous garantira, lui aussi, une lisibilité en toutes circonstances. Les zones fonctionnelles de l’ensemble des MTX Compact sont vastes, cohérentes et hiérarchisées, et les connexions mesure facilement accessibles, puisque situées en façade. Sur le générateur et le multimètre, la sélection des fonctions primaires s’établit directement au moyen de touches avec leds de validation intégrées. Un encodeur performant permet de réaliser efficacement les réglages et des touches contextuelles en bord d’écran indiquent clairement la configuration. Pour les oscilloscopes, en plus des accès directs aux fonctions essentielles par clavier et aux réglages par encodeur, le pilotage via la souris, sous environnement “Windows-like”, est totalement innovant dans cette catégorie d’appareil. Une technologie de leader, l’innovation jusqu’au bout des doigts Une lisibilité privilégiée, une Interface Homme-Machine conviviale (I.H.M.) Les qualités des MTX ne se limitent pas à leur physique. Ces instruments ont une tête bien faite, grâce notamment à leurs micro-processeurs 16 ou 32 bits de dernière génération, aux logiciels téléchargeables et à la calibration 100% numérique. Du point de vue de la sécurité, une protection électronique réarmable a permis la suppression du fusible secteur sur certains modèles. Tous les modèles de la famille MTX Compact peuvent disposer d’interfaces de communication performantes et du langage standard SCPI. Même le clavier de sélection est à la pointe de la technologie grâce à ses contacts à microswitches qui assurent une durabilité exceptionnelle de plus de 100 000 manoeuvres. Les touches bénéficient, quant à elles, d’une gravure laser inaltérable.

General description The UHF EPCglobal Generation 2 standard allows the commercialized provision of mass adoption of UHF RFID technology for passive smart tags and labels. Main fields of applications are supply chain management and logistics for worldwide use with special consideration of European, US and Chinese frequencies to ensure that operating distances of several meters can be realized. The G2X is a dedicated chip for passive, intelligent tags and labels supporting the EPCglobal Class 1 Generation 2 UHF RFID standard. It is especially suited for applications where operating distances of several meters and high anti-collision rates are required. The G2X is a product out of the NXP Semiconductors UCODE product family. The entire UCODE product family offers anti-collision and collision arbitration functionality. This allows a reader to simultaneously operate multiple labels / tags within its antenna field. A UCODE G2X based label/ tag requires no external power supply. Its contact-less interface generates the power supply via the antenna circuit by propagative energy transmission from the interrogator (reader), while the system clock is generated by an on-chip oscillator. Data transmitted from interrogator to label/tag is demodulated by the interface, and it also modulates the interrogator’s electromagnetic field for data transmission from label/tag to interrogator. A label/tag can be operated without the need for line of sight or battery, as long as it is connected to a dedicated antenna for the targeted frequency range. When the label/tag is within the interrogator’s operating range, the high-speed wireless interface allows data transmission in both directions. In addition to the EPC specifications the G2X offers an integrated EAS (Electronic Article Surveillance) feature and read protection of the memory content. On top of the specification of the G2XL the G2XM offers 512-bit of user memory.

Functional description 12.1 Power transfer The interrogator provides an RF field that powers the tag, equipped with a UCODE G2X. The antenna transforms the impedance of free space to the chip input impedance in order to get the maximum possible power for the G2X on the tag. The RF field, which is oscillating on the operating frequency provided by the interrogator, is rectified to provide a smoothed DC voltage to the analog and digital modules of the IC. The antenna that is attached to the chip may use a DC connection between the two antenna pads. Therefore the G2X also enables loop antenna design. Possible examples of supported antenna structures can be found in the reference antenna design guide. 12.2 Data transfer 12.2.1 Reader to G2X Link An interrogator transmits information to the UCODE G2X by modulating an RF signal in the 840 MHz - 960 MHz frequency range. The G2X receives both information and operating energy from this RF signal. Tags are passive, meaning that they receive all of their operating energy from the interrogator's RF waveform. An interrogator is using a fixed modulation and data rate for the duration of at least an inventory round. It communicates to the G2X by modulating an RF carrier using DSB-ASK, SSB-ASK or PR-ASK with PIE encoding. For further details refer to Section 17, Ref. 1, section 6.3.1.2. Interrogator-to-tag (R=>T) communications. 12.2.2 G2X to reader Link An interrogator receives information from the UCODE G2X by transmitting a continuous-wave RF signal to the tag; the G2X responds by modulating the reflection coefficient of its antenna, thereby generating modulated sidebands used to backscatter an information signal to the interrogator. The system is a reader talks first (RTF) system, meaning that a G2X modulates its antenna reflection coefficient with an information signal only after being directed by the interrogator. G2X backscatter is a combination of ASK and PSK modulation depending on the tuning and bias point. The backscattered data is either modulated with FM0 baseband or Miller sub carrier. For further details refer to Section 17, Ref. 1, section 6.3.1.3. tag-to-interrogator (T=>R) communications. 139037 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013.

[2] New CEPT/ETSI regulations. [ETSI3]. [3] FCC 47 part 15 regulation [FCC1]. [4] These read distances are maximum values for general tags and labels. Practical usable values may be lower due to damping by object materials and environmental conditions. A special tag antenna design can help achieve higher values. The typical write range is > 50% of the read range. Table 8.

Physical layer and signaling 13.1 Reader to G2X communication 13.1.1 Physical layer For interrogator-to-G2X link modulation refer to Section 17, Ref. 1, annex H.1 Baseband waveforms, modulated RF, and detected waveforms. 13.1.2 Modulation An interrogator sends information to one or more G2X by modulating an RF carrier using double-sideband amplitude shift keying (DSB-ASK), single-sideband amplitude shift keying (SSB-ASK) or phase-reversal amplitude shift keying (PR-ASK) using a pulse-interval encoding (PIE) format. The G2X receives the operating energy from this same modulated RF carrier. Section 17, Ref. 1: Annex H, as well as chapter 6.3.1.2.2. The G2X is capable of demodulating all three modulation types. 13.1.3 Data encoding The R=>T link is using PIE. For the definition of the therefore relevant reference time interval for interrogator-to-chip signaling (Tari) refer to Section 17, Ref. 1, chapter 6.3.1.2.3. The Tari is specified as the duration of a data-0. 13.1.4 Data rates Interrogators shall communicate using Tari values between 6.25 s and 25 s, inclusive. For interrogator compliance evaluation the preferred Tari values of 6.25 s, 12.5 s or 25 s should be used. For further details refer to Section 17, Ref. 1, chapter 6.3.1.2.4. 13.1.5 RF envelope for R=>T A specification of the relevant RF envelope parameters can be found in Section 17, Ref. 1, chapter 6.3.1.2.5. 13.1.6 Interrogator power-up/down waveform For a specification of the interrogator power-up and power-down RF envelope and waveform parameters refer to Section 17, Ref. 1, chapters 6.3.1.2.6 and 6.3.1.2.7. 13.1.7 Preamble and frame-sync An interrogator shall begin all R=>T signaling with either a preamble or a frame-sync. A preamble shall precede a Query command and denotes the start of an inventory round. For a definition and explanation of the relevant R=>T preamble and frame-sync refer to Section 17, Ref. 1, chapter 6.3.1.2.8. 139037 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013.

The G2X backscatters by switching the reflection coefficient of its antenna between two states in accordance with the data being sent. For further details refer to Section 17, Ref. 1, chapter 6.3.1.3. 13.2.1 Modulation The UCODE G2X communicates information by backscatter-modulating the amplitude and/or phase of the RF carrier. Interrogators shall be capable of demodulating either demodulation type. 13.2.2 Data encoding The encoding format, selected in response to interrogator commands, is either FM0 baseband or Miller-modulated subaltern. The interrogator commands the encoding choice 13.2.2.1 FM0 baseband FM0 inverts the baseband phase at every symbol boundary; a data-0 has an additional mid-symbol phase inversion. For details on FM0 and generator state diagram, FM0 symbols and sequences and how FM0 transmissions should be terminated refer to Section 17, Ref. 1, chapter 6.3.1.3. 13.2.2.2 FM0 Preamble T=>R FM0 signaling begin with one of two defined preambles, depending on the value of the TRext bit specified in the Query command that initiated the inventory round. For further details refer to Section 17, Ref. 1, chapter 6.3.1.3. 13.2.2.3 Miller-modulated sub carrier Baseband Miller inverts its phase between two data-0s in sequence. Baseband Miller also places a phase inversion in the middle of a data-1 symbol. For details on Miller-modulated sub carrier, generator state diagram, sub carrier sequences and terminating sub carrier transmissions refer to Section 17, Ref. 1, chapter 6.3.1.3. 13.2.2.4 Miller sub carrier preamble T=>R sub carrier signaling begins with one of the two defined preambles. The choice depends on the value of the TRext bit specified in the Query command that initiated the inventory round. For further details refer to Section 17, Ref. 1, chapter 6.3.1.3. 13.2.3 Data rates The G2X IC supports tag to interrogator data rates and link frequencies as specified in Section 17, Ref. 1, chapter 6.3.1.3. 139037 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013.

This time is referred to as T2 and can vary between 3.0 Tpri and 20 Tpri. For a more detailed description refer to Section 17, Ref. 1, chapter 6.3.1.6. 13.3.2 Start-up time For a detailed description refer to Section 17, Ref. 1, chapter 6.3.1.3.4. 13.3.3 Persistence time An interrogator chooses one of four sessions and inventories tags within that session (denoted S0, S1, S2, and S3). The interrogator and associated UCODE G2X population operate in one and only one session for the duration of an inventory round (defined above). For each session, a corresponding inventoried flag is maintained. Sessions allow tags to keep track of their inventoried status separately for each of four possible time-interleaved inventory processes, using an independent inventoried flag for each process. Two or more interrogators can use sessions to independently inventory a common UCODE G2X chip population. A session flag indicates whether a G2X may respond to an interrogator. G2X chips maintain a separate inventoried flag for each of four sessions; each flag has symmetric A and B values. Within any given session, interrogators typically inventory tags from A to B followed by a re-inventory of tags from B back to A (or vice versa). Additionally, the G2X has implemented a selected flag, SL, which an interrogator may assert or deassert using a Select command. For a description of Inventoried flags S0 – S3 refer to Section 17, Ref. 1 chapter 6.3.2.2 and for a description of the Selected flag refer to Section 17, Ref. 1, chapter 6.3.2.3. For tag flags and respective persistence time refer to Section 17, Ref. 1, table 6.14. 13.4 Bit and byte ordering The transmission order for all R=>T and T=>R communications respects the following conventions: • within each message, the most-significant word is transmitted first, and • within each word, the most-significant bit (MSB) is transmitted first, whereas one word is composed of 16 bits. To represent memory addresses and mask lengths EBV-8 values are used. An extensible bit vector (EBV) is a data structure with an extensible data range.

In general, "invalid" means a command that (1) is incorrect given the current the G2X state, (2) is unsupported by the G2X, (3) has incorrect parameters, (4) has a CRC error, (5) specifies an incorrect session, or (6) is in any other way not recognized or not executable by the G2X. The actual definition of "invalid" is state-specific and defined, for each G2X state, in n Section 17, Ref. 1 Annex B and Annex C. All UCODE G2X backscatter error codes are summarized in Section 17, Ref. 1 Error codes, Annex I. For a detailed description of the individual backscatter error situations which are command specific please refer to the Section 17, Ref. 1 individual command description section 6.3.2.10. 13.6 CRC A CRC-16 is a cyclic-redundancy check that an interrogator uses when protecting certain R=>T commands, and the G2X uses when protecting certain backscattered T=>R sequences. To generate a CRC-16 an interrogator or the G2X first generates the CRC-16 precursor shown in Section 17, Ref. 1 Table 6.11, then take the ones-complement of the generated precursor to form the CRC-16. For a detailed description of the CRC-16 generation and handling rules refer to Section 17, Ref. 1, chapter 6.3.2.1. The CRC-5 is only used to protect the Query command (out of the mandatory command set). It is calculated out of X5 + X3 + 1. For a more detailed CRC-5 description refer to Section 17, Ref. 1, table 6.12. For exemplary schematic diagrams for CRC-5 and CRC-16 encoder/decoder refer to Section 17, Ref. 1, Annex F. For a CRC calculation example refer to Section 15.1, Table 27 and Table 28. 139037 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013. All rights reserved.

TAG selection, inventory and access This section contains all information including commands by which a reader selects, inventories, and accesses a G2X population An interrogator manages UCODE G2X equipped tag populations using three basic operations. Each of these operations comprises one or more commands. The operations are defined as follows Select: The process by which an interrogator selects a tag population for inventory and access. Interrogators may use one or more Select commands to select a particular tag population prior to inventory. Inventory: The process by which an interrogator identifies UCODE G2X equipped tags. An interrogator begins an inventory round by transmitting a Query command in one of four sessions. One or more G2X may reply. The interrogator detects a single G2X reply and requests the PC, EPC, and CRC-16 from the chip. An inventory round operates in one and only one session at a time. For an example of an interrogator inventorying and accessing a single G2X refer to Section 17, Ref. 1, Annex E. Access: The process by which an interrogator transacts with (reads from or writes to) individual G2X. An individual G2X must be uniquely identified prior to access. Access comprises multiple commands, some of which employ one-time-pad based cover-coding of the R=>T link. 139037 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013.

The user memory can be accessed via Select, Read or Write command and it may be write locked, permanently write locked, unlocked or permanently unlocked. In addition reading of not only of the User Memory but of the whole memory including EPC and TID can be protected by using the custom ReadProtect command. 14.1.1.2 Special behavior of user memory address 1Fh WRITE or SELECT of user memory address 1Fh will falsely set an error flag. This will affect the subsequent READ or SELECT. The following commands will falsely set an internal error flag (without actually causing an error): 1) WRITE to user memory with WordPtr=1Fh 2) SELECT to user memory with compare mask ending at bitaddress 1FFh (e.g. Pointer=1FEh, length=1 or Pointer=1FDh, length=2 …) Note: The error flag is set independent of the chip state (also chips in the e.g. Ready state are affected). The falsely set error flag will affect the following sub sequential commands: A) READ command with WordCount=0 falsely responds with "memory overrun" error B) SELECT command with Length<>0 falsely assumes non existing memory location The behavior can be avoided with: • Turning off the RF carrier to reset the chip (This is what readers typically do!). • Using the READ command with WordCount<>0. • Sending other command prior to READ or SELECT (e.g. WRITE to address<>1Fh, ReqRN) or executing READ or SELECT two times. Remark: The WRITE operation itself is not affected by this problem i.e. data is written properly! With commercially available readers this behavior is typically not observed. 14.1.1.3 Supported EPC types The EPC types are defined in the EPC Tag Standards document from EPCglobal. These standards define completely that portion of EPC tag data that is standardized, including how that data is encoded on the EPC tag itself (i.e. the EPC Tag Encodings), as well as how it is encoded for use in the information systems layers of the EPC Systems Network (i.e. the EPC URI or Uniform Resource Identifier Encodings). The EPC Tag Encodings include a Header field followed by one or more Value Fields. The Header field indicates the length of the Values Fields and contains a numbering system identifier (NSI). The Value Fields contain a unique EPC Identifier and optional Filter Value when the latter is judged to be important to encode on the tag itself. 139037 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2013.

Executing ReadProtect from the Secured state will set the ReadProtect-bit to '1'. With the ReadProtect-Bit set the G2X will continue to work unaffected but fail its content. Following commands will be disabled: Read, Write, Kill, Lock, Access, ReadProtect, ChangeEAS, EAS Alarm and Calibrate. The G2X will only react upon an anticollision with Select, Query, QueryRep, QueryAdjust, ACK (no truncated reply), NAK, ReqRN but reply with zeros as EPC and CRC-16 content (except PC/password). ACK will return zeros except for the PC. The read protection can be removed by executing Reset ReadProtect. The ReadProtect-Bit will than be cleared. Devices whose access password is zero will ignore the command. A frame-sync must be prepended the command. After sending the ReadProtect command an interrogator shall transmit CW for the lesser of TReply or 20 ms, where TReply is the time between the interrogator's ReadProtect command and the backscattered reply. An interrogator may observe three possible responses after sending a ReadProtect, depending on the success or failure of the operation: • ReadProtect succeeds: After completing the ReadProtect the G2X shall backscatter the reply shown in Table 14 comprising a header (a 0-bit), the tag's handle, and a CRC-16 calculated over the 0-bit and handle. Immediately after this reply the G2X will render itself to this ReadProtect mode. If the interrogator observes this reply within 20 ms then the ReadProtect completed successfully. • The G2X encounters an error: The G2X will backscatter an error code during the CW period rather than the reply shown in the EPCglobal Spec (see Annex I for error-code definitions and for the reply format). • ReadProtect does not succeed: If the interrogator does not observe a reply within 20 ms then the ReadProtect did not complete successfully. The interrogator may issue a Req_RN command (containing the handle) to verify that the G2X is still in the interrogation zone, and may re-initiate the ReadProtect command.

The G2X will execute Reset ReadProtect from the Open or Secured states. If a G2X in the Open or Secured states receives a Reset ReadProtect with a valid CRC-16 and a valid handle but an incorrect access password, it will not reply and transit to the Arbitrate state. If a G2X in the Open or Secured states receives a Reset ReadProtect with a valid CRC-16 and a valid handle but the ReadProtect-Bit is not set ('0'), it will not change the ReadProtect-Bit but backscatter the reply shown in Table 17. If a G2X in the Open or Secured receives a Reset ReadProtect with a valid CRC-16 but an invalid handle, or it receives a Reset ReadProtect before which the immediately preceding command was not a Req_RN, it will ignore the Reset ReadProtect and remain in its current state. A frame-sync must be prepended the Reset ReadProtect command. After sending a Reset ReadProtect an interrogator shall transmit CW for the lesser of TReply or 20 ms, where TReply is the time between the interrogator's Reset ReadProtect command and the G2X backscattered reply. An interrogator may observe three possible responses after sending a Reset ReadProtect, depending on the success or failure of the operation: • Write succeeds: After completing the Reset ReadProtect a G2X will backscatter the reply shown in Table 17 comprising a header (a 0-bit), the handle, and a CRC-16 calculated over the 0-bit and handle. If the interrogator observes this reply within 20 ms then the Reset ReadProtect completed successfully. • The G2X encounters an error: The G2X will backscatter an error code during the CW period rather than the reply shown in Table 17 (see EPCglobal Spec for error-code definitions and for the reply format). • Write does not succeed: If the interrogator does not observe a reply within 20 ms then the Reset ReadProtect did not complete successfully. The interrogator may issue a Req_RN command (containing the handle) to verify that the G2X is still in the interrogation zone, and may reissue the Reset ReadProtect command. The G2X reply to the Reset ReadProtect command will use the extended preamble shown in EPCglobal Spec (Figure 6.11 or Figure 6.15), as appropriate (i.e. a G2X will reply as if TRext=1 regardless of the TRext value in the Query that initiated the round.

With an EAS-Alarm bit set to '1' the tag will reply to an EAS_Alarm command by backscattering a 64 bit alarm code without the need of a Select or Query. The EAS is a built-in solution so no connection to a backend database is required. As it is a custom command no Select or Query is required to detect the EAS state enabling fast, reliable and offline article surveillance. ChangeEAS can be executed from the Secured state only. The command will be ignored if the Access Password is zero, the command will also be ignored with an invalid CRC-16 or an invalid handle, the G2X will than remain in the current state. The CRC-16 is calculated from the first command-code bit to the last handle bit. A frame-sync must be prepended the command. The G2X reply to a successful ChangeEAS will use the extended preamble, as appropriate (i.e. a Tag shall reply as if TRext=1) regardless of the TRext value in the Query that initiated the round. After sending a ChangeEAS an interrogator shall transmit CW for less than TReply or 20 ms, where TReply is the time between the interrogator's ChangeEAS command and the G2X backscattered reply. An interrogator may observe three possible responses after sending a ChangeEAS, depending on the success or failure of the operation • Write succeeds: After completing the ChangeEAS a G2X will backscatter the reply shown in Table 20 comprising a header (a 0-bit), the handle, and a CRC-16 calculated over the 0-bit and handle. If the interrogator observes this reply within 20 ms then the ChangeEAS completed successfully. • The G2X encounters an error: The G2X will backscatter an error code during the CW period rather than the reply shown in Table 20 (see EPCglobal Spec for error-code definitions and for the reply format). • Write does not succeed: If the interrogator does not observe a reply within 20 ms then the ChangeEAS did not complete successfully. The interrogator may issue a Req_RN command (containing the handle) to verify that the G2X is still in the interrogator's field, and may reissue the ChangeEAS command. Upon receiving a valid ChangeEAS command a G2X will perform the commanded set/reset operation of the EAS_Alarm-Bit. If EAS-Bit is set, the EAS_Alarm command will be available after the next power up and reply the 64 bit EAS code upon execution. Otherwise the EAS_Alarm command will be ignored. Table 18.

The EAS feature of the G2X is available after enabling it by sending a ChangeEAS command described in Section 14.12.3 “ChangeEAS”. With an EAS-Alarm bit set to '1' the G2X will reply to an EAS_Alarm command by backscattering a fixed 64 bit alarm code. A G2X will reply to an EAS_Alarm command from the ready state only. If the EAS-Alarm bit is reset ('0') by sending a ChangeEAS command in the password protected Secure state the G2X will not reply to an EAS_Alarm command. The EAS_Alarm command is structured as following: • 16 bit command • 16 bit inverted command • DR (TRcal divide ratio) sets the T=>R link frequency as described in EPCglobal Spec. 6.3.1.2.8 and Table 6.9. • M (cycles per symbol) sets the T=>R data rate and modulation format as shown in EPCglobal Spec. Table 6.10. • TRext chooses whether the T=>R preamble is prepended with a pilot tone as described in EPCglobal Spec. 6.3.1.3. A preamble must be prepended the EAS_Alarm command according EPCglobal Spec, 6.3.1.2.8. Upon receiving an EAS_Alarm command the tag loads the CRC5 register with 01001b and backscatters the 64 bit alarm code accordingly. The reader is now able to calculate the CRC5 over the backscattered 64 bits received to verify the received code. Table 21.

The host controller allocates the USB bandwidth to attached devices through a token-based protocol. The bus supports hot-plugging and dynamic configuration of the devices. The host controller initiates all transactions. The LPC11U3x USB interface consists of a full-speed device controller with on-chip PHY (PHYsical layer) for device functions. Remark: Configure the LPC11U3x in default power mode with the power profiles before using the USB (see Section 7.18.5.1). Do not use the USB with the part in performance, efficiency, or low-power mode. 7.9.1 Full-speed USB device controller The device controller enables 12 Mbit/s data exchange with a USB Host controller. It consists of a register interface, serial interface engine, and endpoint buffer memory. The serial interface engine decodes the USB data stream and writes data to the appropriate endpoint buffer. The status of a completed USB transfer or error condition is indicated via status registers. If enabled, an interrupt is generated. 7.9.1.1 Features • Dedicated USB PLL available. • Fully compliant with USB 2.0 specification (full speed). • Supports 10 physical (5 logical) endpoints including one control endpoint. • Single and double buffering supported. • Each non-control endpoint supports bulk, interrupt, or isochronous endpoint types. • Supports wake-up from Deep-sleep mode and Power-down mode on USB activity and remote wake-up. • Supports SoftConnect. 7.10 I/O Handler (LPC11U37HFBD64/401 only) The I/O Handler is a software library-supported hardware engine for emulating serial interfaces and off-loading the CPU for processing-intensive functions. The I/O Handler can emulate, among others, DMA and serial interfaces such as UART, I2C, or I2S with no or very low additional CPU load. The software libraries are available with supporting LPC11U3X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved. Product data sheet Rev. 2.2 — 11 March 2014 21 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller application notes from NXP (see http://www.LPCware.com.) LPCXpresso, Keil, and IAR IDEs are supported. I/O Handler library code must be executed from the memory area 0x2000 0000 to 0x2000 07FF. This memory is not available for other use. For application examples, see Section 11.8 “I/O Handler software library applications”. Each I/O Handler library uses a specific subset of I/O Handler pins and in some cases other pins and peripherals such as the counter/timers. 7.11 USART The LPC11U3x contains one USART. The USART includes full modem control, support for synchronous mode, and a smart card interface. The RS-485/9-bit mode allows both software address detection and automatic address detection using 9-bit mode. The USART uses a fractional baud rate generator. Standard baud rates such as 115200 Bd can be achieved with any crystal frequency above 2 MHz. 7.11.1 Features • Maximum USART data bit rate of 3.125 Mbit/s. • 16 byte receive and transmit FIFOs. • Register locations conform to 16C550 industry standard. • Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B. • Built-in fractional baud rate generator covering wide range of baud rates without a need for external crystals of particular values. • Fractional divider for baud rate control, auto baud capabilities and FIFO control mechanism that enables software flow control implementation. • Support for RS-485/9-bit mode. • Support for modem control. • Support for synchronous mode. • Includes smart card interface. 7.12 SSP serial I/O controller The SSP controllers operate on a SSP, 4-wire SSI, or Microwire bus. The controller can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bit to 16 bit of data flowing from the master to the slave and from the slave to the master. In practice, often only one of these data flows carries meaningful data. 7.12.1 Features • Maximum SSP speed of 25 Mbit/s (master) or 4.17 Mbit/s (slave) (in SSP mode) • Compatible with Motorola SPI (Serial Peripheral Interface), 4-wire Texas Instruments SSI (Serial Synchronous Interface), and National Semiconductor Microwire buses • Synchronous serial communication • Master or slave operation LPC11U3X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial CLock line (SCL) and a Serial DAta line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the capability to both receive and send information (such as memory). Transmitters and/or receivers can operate in either master or slave mode, depending on whether the chip has to initiate a data transfer or is only addressed. The I2C-bus is a multi-master bus, and more than one bus master connected to the interface can be controlled the bus. 7.13.1 Features • The I2C-interface is an I2C-bus compliant interface with open-drain pins.

Product data sheet Rev. 2.2 — 11 March 2014 23 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller 7.15 General purpose external event counter/timers The LPC11U3x includes two 32-bit counter/timers and two 16-bit counter/timers. The counter/timer is designed to count cycles of the system derived clock. It can optionally generate interrupts or perform other actions at specified timer values, based on four match registers. Each counter/timer also includes one capture input to trap the timer value when an input signal transitions, optionally generating an interrupt. 7.15.1 Features • A 32-bit/16-bit timer/counter with a programmable 32-bit/16-bit prescaler. • Counter or timer operation. • Up to two capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event can also generate an interrupt. • Four match registers per timer that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Up to four external outputs corresponding to match registers, with the following capabilities: – Set LOW on match. – Set HIGH on match. – Toggle on match. – Do nothing on match. • The timer and prescaler can be configured to be cleared on a designated capture event. This feature permits easy pulse-width measurement by clearing the timer on the leading edge of an input pulse and capturing the timer value on the trailing edge. 7.16 System tick timer The ARM Cortex-M0 includes a system tick timer (SYSTICK) that is intended to generate a dedicated SYSTICK exception at a fixed time interval (typically 10 ms). 7.17 Windowed WatchDog Timer (WWDT) The purpose of the WWDT is to prevent an unresponsive system state. If software fails to update the watchdog within a programmable time window, the watchdog resets the microcontroller 7.17.1 Features • Internally resets chip if not periodically reloaded during the programmable time-out period. • Optional windowed operation requires reload to occur between a minimum and maximum time period, both programmable. • Optional warning interrupt can be generated at a programmable time before watchdog time-out.

The clock source selection provides a wide range of potential timing choices of watchdog operation under different power conditions. 7.18 Clocking and power control 7.18.1 Integrated oscillators The LPC11U3x include three independent oscillators: the system oscillator, the Internal RC oscillator (IRC), and the watchdog oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Following reset, the LPC11U3x operates from the internal RC oscillator until software switches to a different clock source. The IRC allows the system to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 7 for an overview of the LPC11U3x clock generation.

Product data sheet Rev. 2.2 — 11 March 2014 25 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller 7.18.1.1 Internal RC oscillator The IRC can be used as the clock source for the WDT, and/or as the clock that drives the system PLL and then the CPU. The nominal IRC frequency is 12 MHz. Upon power-up, any chip reset, or wake-up from Deep power-down mode, the LPC11U3x use the IRC as the clock source. Software can later switch to one of the other available clock sources. Fig 7.

All rights reserved. Product data sheet Rev. 2.2 — 11 March 2014 26 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller 7.18.1.2 System oscillator The system oscillator can be used as the clock source for the CPU, with or without using the PLL. On the LPC11U3x, use the system oscillator to provide the clock source to USB. The system oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. 7.18.1.3 Watchdog oscillator The watchdog oscillator can be used as a clock source that directly drives the CPU, the watchdog timer, or the CLKOUT pin. The watchdog oscillator nominal frequency is programmable between 9.4 kHz and 2.3 MHz. The frequency spread over processing and temperature is 40 % (see also Table 13). 7.18.2 System PLL and USB PLL The LPC11U3x contain a system PLL and a dedicated PLL for generating the 48 MHz USB clock. The system and USB PLLs are identical. The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz. To support this frequency range, an additional divider keeps the CCO within its frequency range while the PLL is providing the desired output frequency. The output divider can be set to divide by 2, 4, 8, or 16 to produce the output clock. The PLL output frequency must be lower than 100 MHz. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset. Software can enable the PLL later. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 s. 7.18.3 Clock output The LPC11U3x feature a clock output function that routes the IRC oscillator, the system oscillator, the watchdog oscillator, or the main clock to an output pin. 7.18.4 Wake-up process The LPC11U3x begin operation by using the 12 MHz IRC oscillator as the clock source at power-up and when awakened from Deep power-down mode . This mechanism allows chip operation to resume quickly. If the application uses the main oscillator or the PLL, software must enable these components and wait for them to stabilize. Only then can the system use the PLL and main oscillator as a clock source. 7.18.5 Power control The LPC11U3x support various power control features. There are four special modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. The CPU clock rate can also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This power control mechanism allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals. This register allows fine-tuning of power LPC11U3X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

Selected peripherals have their own clock divider which provides even better power control. 7.18.5.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through simple calls to the power profile. The power configuration routine configures the LPC11U3x for one of the following power modes: • Default mode corresponding to power configuration after reset. • CPU performance mode corresponding to optimized processing capability. • Efficiency mode corresponding to optimized balance of current consumption and CPU performance. • Low-current mode corresponding to lowest power consumption. In addition, the power profile includes routines to select the optimal PLL settings for a given system clock and PLL input clock. Remark: When using the USB, configure the LPC11U3x in Default mode. 7.18.5.2 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core. In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and can generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, by memory systems and related controllers, and by internal buses. 7.18.5.3 Deep-sleep mode In Deep-sleep mode, the LPC11U3x is in Sleep-mode and all peripheral clocks and all clock sources are off except for the IRC. The IRC output is disabled unless the IRC is selected as input to the watchdog timer. In addition all analog blocks are shut down and the flash is in stand-by mode. In Deep-sleep mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC11U3x can wake up from Deep-sleep mode via reset, selected GPIO pins, a watchdog timer interrupt, or an interrupt generating USB port activity. Deep-sleep mode saves power and allows for short wake-up times. 7.18.5.4 Power-down mode In Power-down mode, the LPC11U3x is in Sleep-mode and all peripheral clocks and all clock sources are off except for watchdog oscillator if selected. In addition all analog blocks and the flash are shut down. In Power-down mode, the application can keep the BOD circuit running for BOD protection. The LPC11U3x can wake up from Power-down mode via reset, selected GPIO pins, a watchdog timer interrupt, or an interrupt generating USB port activity.

Product data sheet Rev. 2.2 — 11 March 2014 28 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller Power-down mode reduces power consumption compared to Deep-sleep mode at the expense of longer wake-up times. 7.18.5.5 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip except for the WAKEUP pin. The LPC11U3x can wake up from Deep power-down mode via the WAKEUP pin. The LPC11U3x can be prevented from entering Deep power-down mode by setting a lock bit in the PMU block. Locking out Deep power-down mode enables the application to keep the watchdog timer or the BOD running at all times. When entering Deep power-down mode, an external pull-up resistor is required on the WAKEUP pin to hold it HIGH. Pull the RESET pin HIGH to prevent it from floating while in Deep power-down mode. 7.18.6 System control 7.18.6.1 Reset Reset has four sources on the LPC11U3x: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller. A LOW-going pulse as short as 50 ns resets the part. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. In Deep power-down mode, an external pull-up resistor is required on the RESET pin. 7.18.6.2 Brownout detection The LPC11U3x includes up to four levels for monitoring the voltage on the VDD pin. If this voltage falls below one of the selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC to cause a CPU interrupt. Alternatively, software can monitor the signal by reading a dedicated status register. Four threshold levels can be selected to cause a forced reset of the chip. 7.18.6.3 Code security (Code Read Protection - CRP) CRP provides different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) and In-System Programming (ISP) can be restricted. Programming a specific pattern into a dedicated flash location invokes CRP. IAP commands are not affected by the CRP. In addition, ISP entry via the PIO0_1 pin can be disabled without enabling CRP. For details, see the LPC11Uxx user manual. There are three levels of Code Read Protection: LPC11U3X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved. Product data sheet Rev. 2.2 — 11 March 2014 29 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller 1. CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors cannot be erased. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected, fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using PIO0_1 pin as well. If necessary, the application must provide a flash update mechanism using IAP calls or using a call to the reinvoke ISP command to enable flash update via the USART. In addition to the three CRP levels, sampling of pin PIO0_1 for valid user code can be disabled. For details, see the LPC11Uxx user manual. 7.18.6.4 APB interface The APB peripherals are located on one APB bus. 7.18.6.5 AHBLite The AHBLite connects the CPU bus of the ARM Cortex-M0 to the flash memory, the main static RAM, and the ROM. 7.18.6.6 External interrupt inputs All GPIO pins can be level or edge sensitive interrupt inputs. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.

Serial wire debug functions are supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0 is configured to support up to four breakpoints and two watch points. The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM SWD debug (RESET = HIGH). The ARM SWD debug port is disabled while the LPC11U3x is in reset. To perform boundary scan testing, follow these steps: 1. Erase any user code residing in flash. 2. Power up the part with the RESET pin pulled HIGH externally. 3. Wait for at least 250 s. 4. Pull the RESET pin LOW externally. 5. Perform boundary scan operations. 6. Once the boundary scan operations are completed, assert the TRST pin to enable the SWD debug mode, and release the RESET pin (pull HIGH). Remark: The JTAG interface cannot be used for debug purposes.

[3] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 8. [4] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the ideal curve. See Figure 8. [5] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset error, and the straight line which fits the ideal transfer curve. See Figure 8. [6] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated ADC and the ideal transfer curve. See Figure 8.

[2] Parameters are valid over operating temperature range unless otherwise specified. [3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [5] Cb = total capacitance of one bus line in pF. [6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. Table 14.

Product data sheet Rev. 2.2 — 11 March 2014 49 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller [7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. Fig 23.

Application information 11.1 Suggested USB interface solutions The USB device can be connected to the USB as self-powered device (see Figure 27) or bus-powered device (see Figure 28). On the LPC11U3x, the PIO0_3/USB_VBUS pin is 5 V tolerant only when VDD is applied and at operating voltage level. Therefore, if the USB_VBUS function is connected to the USB connector and the device is self-powered, the USB_VBUS pin must be protected for situations when VDD = 0 V. If VDD is always greater than 0 V while VBUS = 5 V, the USB_VBUS pin can be connected directly to the VBUS pin on the USB connector. For systems where VDD can be 0 V and VBUS is directly applied to the VBUS pin, precautions must be taken to reduce the voltage to below 3.6 V, which is the maximum allowable voltage on the USB_VBUS pin in this case. One method is to use a voltage divider to connect the USB_VBUS pin to the VBUS on the USB connector. The voltage divider ratio should be such that the USB_VBUS pin will be greater than 0.7VDD to indicate a logic HIGH while below the 3.6 V allowable maximum voltage. For the following operating conditions VBUSmax = 5.25 V VDD = 3.6 V, the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V. Fig 27.

All rights reserved. Product data sheet Rev. 2.2 — 11 March 2014 55 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller For a bus-powered device, the VBUS signal does not need to be connected to the USB_VBUS pin (see Figure 28). The USB_CONNECT function can additionally be connected as shown in Figure 27 to prevent the USB from timing out when there is a significant delay between power-up and handling USB traffic. Remark: When a bus-powered circuit as shown in Figure 28 is used, configure the PIO0_3/USB_VBUS pin for GPIO (PIO0_3) in the IOCON block to ensure that the USB_CONNECT signal can still be controlled by software. For details on the soft-connect feature, see the LPC11U3x user manual (Ref. 1). Remark: When a self-powered circuit is used without connecting VBUS, configure the PIO0_3/USB_VBUS pin for GPIO (PIO0_3) and provide software that can detect the host presence through some other mechanism before enabling USB_CONNECT and the soft-connect feature. Enabling the soft-connect without host presence will lead to USB compliance failure. Fig 28.

If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV (RMS) is needed. In slave mode, couple the input clock signal with a capacitor of 100 pF (Figure 29), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This signal corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 30 and in Table 18 and Table 19. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (L, CL and RS represent the fundamental frequency). Capacitance CP in Figure 30 represents the parallel package capacitance and must not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal manufacturer. Fig 29.

Therefore, filter the power supply line adequately. • To improve the ADC performance in a noisy environment, put the device in Sleep mode during the ADC conversion. 11.8 I/O Handler software library applications The following sections provide application examples for the I/O Handler software library. All library examples make use of the I/O Handler hardware to extend the functionality of the part through software library calls. The libraries are available on http://www.LPCware.com. 11.8.1 I/O Handler I2S The I/O Handler software library provides functions to emulate an I2S master transmit interface using the I/O Handler hardware block. The emulated I2S interface loops over a 1 kB buffer, transmitting the datawords according to the I2S protocol. Interrupts are generated every time when the first 512 bytes have been transmitted and when the last 512 bytes have been transmitted. This allows the ARM core to load the free portion of the buffer with new data, thereby enabling streaming audio. Two channels with 16-bit per channel are supported. The code size of the software library is 1 kB and code must be executed from the SRAM1 memory area reserved for the I/O Handler code. 11.8.2 I/O Handler UART The I/O Handler UART library emulates one additional full-duplex UART. The emulated UART can be configured for 7 or 8 data bits, no parity, and 1 or 2 stop bits. The baud rate is configurable up to 115200 baud. The RXD signal is available on three I/O Handler pins (IOH_6, IOH_16, IOH_20), while TXD and CTS are available on all 21 I/O Handler pins. The code size of the software library is about 1.2 kB and code must be executed from the SRAM1 memory area reserved for the I/O Handler code.

Product data sheet Rev. 2.2 — 11 March 2014 61 of 77 NXP Semiconductors LPC11U3x 32-bit ARM Cortex-M0 microcontroller 11.8.3 I/O Handler I2C The I/O Handler I2C library allows to have an additional I2C-bus master. I2C read, I2C write and combined I2C read/write are supported. Data is automatically read from and written to user-defined buffers. The I/O Handler I2C library combined with the on-chip I2C module allows to have two distinct I2C buses, allowing to separate low-speed from high-speed devices or bridging two I2C buses. 11.8.4 I/O Handler DMA The I/O Handler DMA library offers DMA-like functionality. Four types of transfer are supported: memory to memory, memory to peripheral, peripheral to memory and peripheral to peripheral. Supported peripherals are USART, SSP0/1, ADC and GPIO. DMA transfers can be triggered by the source/target peripheral, software, counter/timer module CT16B1, or I/O Handler pin PIO1_6/IOH_16.

General description The PCA9545A/45B/45C is a quad bidirectional translating switch controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. Four interrupt inputs, INT0 to INT3, one for each of the downstream pairs, are provided. One interrupt output, INT, acts as an AND of the four interrupt inputs. An active LOW reset input allows the PCA9545A/45B/45C to recover from a situation where one of the downstream I2C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets the I2C-bus state machine and causes all the channels to be deselected as does the internal power-on reset function. The pass gates of the switches are constructed such that the VDD pin can be used to limit the maximum high voltage which is passed by the PCA9545A/45B/45C. This allows the use of different bus voltages on each pair, so that 1.8 V or 2.5 V or 3.3 V parts can communicate with 5 V parts without any additional protection. External pull-up resistors pull the bus up to the desired voltage level for each channel. All I/O pins are 5 V tolerant. The PCA9545A, PCA9545B and PCA9545C are identical except for the fixed portion of the slave address. 2. Features and benefits 1-of-4 bidirectional translating switches I2C-bus interface logic; compatible with SMBus standards 4 active LOW interrupt inputs Active LOW interrupt output Active LOW reset input 2 address pins allowing up to 4 devices on the I2C-bus Alternate address versions A, B and C allow up to a total of 12 devices on the bus for larger systems or to resolve address conflicts Channel selection via I2C-bus, in any combination Power-up with all switch channels deselected Low Ron switches Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses No glitch on power-up Supports hot insertion Low standby current Operating power supply voltage range of 2.3 V to 5.5 V PCA9545A/45B/45C 4-channel I2C-bus switch with interrupt logic and reset Rev. 9 — 5 May 2014 Product data sheet PCA9545A_45B_45C All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

The VSS pin must be connected to supply ground for proper device operation. For enhanced thermal, electrical, and board-level performance, the exposed pad must be soldered to the board using a corresponding thermal pad on the board, and for proper heat conduction through the board thermal vias must be incorporated in the PCB in the thermal pad region.

Functional description Refer to Figure 1 “Block diagram of PCA9545A/45B/45C”. 6.1 Device address Following a START condition, the bus master must output the address of the slave it is accessing. The address of the PCA9545A is shown in Figure 5. To conserve power, no internal pull-up resistors are incorporated on the hardware selectable address pins and they must be pulled HIGH or LOW. The last bit of the slave address defines the operation to be performed. When set to logic 1, a read is selected while a logic 0 selects a write operation. The PCA9545BPW and PCA9545CPW are alternate address versions if needed for larger systems or to resolve conflicts. The data sheet references the PCA9545A, but the PCA9545B and PCA9545C function identically except for the slave address. Fig 5. Slave address PCA9545A Fig 6. Slave address PCA9545B Fig 7.

Product data sheet Rev. 9 — 5 May 2014 7 of 32 NXP Semiconductors PCA9545A/45B/45C 4-channel I2C-bus switch with interrupt logic and reset 6.2 Control register Following the successful acknowledgement of the slave address, the bus master sends a byte to the PCA9545A/45B/45C, which is stored in the control register. If multiple bytes are received by the PCA9545A/45B/45C, it saves the last byte received. This register can be written and read via the I2C-bus. 6.2.1 Control register definition One or several SCx/SDx downstream pair, or channel, is selected by the contents of the control register. This register is written after the PCA9545A/45B/45C has been addressed. The 4 LSBs of the control byte are used to determine which channel is to be selected. When a channel is selected, the channel will become active after a STOP condition has been placed on the I2C-bus. This ensures that all SCx/SDx lines are in a HIGH state when the channel is made active, so that no false conditions are generated at the time of connection. Remark: Several channels can be enabled at the same time. Example: B3 = 0, B2 = 1, B1 = 1, B0 = 0, means that channel 0 and channel 3 are disabled and channel 1 and channel 2 are enabled. Care should be taken not to exceed the maximum bus capacity. Fig 8.

Product data sheet Rev. 9 — 5 May 2014 8 of 32 NXP Semiconductors PCA9545A/45B/45C 4-channel I2C-bus switch with interrupt logic and reset 6.2.2 Interrupt handling The PCA9545A/45B/45C provides 4 interrupt inputs, one for each channel, and one open-drain interrupt output. When an interrupt is generated by any device, it is detected by the PCA9545A/45B/45C and the interrupt output is driven LOW. The channel does not need to be active for detection of the interrupt. A bit is also set in the control register. Bit 4 through bit 7 of the control register corresponds to channel 0 through channel 3 of the PCA9545A/45B/45C, respectively. Therefore, if an interrupt is generated by any device connected to channel 1, the state of the interrupt inputs is loaded into the control register when a read is accomplished. Likewise, an interrupt on any device connected to channel 0 would cause bit 4 of the control register to be set on the read. The master can then address the PCA9545A/45B/45C and read the contents of the control register to determine which channel contains the device generating the interrupt. The master can then reconfigure the PCA9545A/45B/45C to select this channel, and locate the device generating the interrupt and clear it. It should be noted that more than one device can provide an interrupt on a channel, so it is up to the master to ensure that all devices on a channel are interrogated for an interrupt. If the interrupt function is not required, the interrupt inputs may be used as general-purpose inputs. If unused, interrupt inputs must be connected to VDD through a pull-up resistor. Remark: Several interrupts can be active at the same time. Example: INT3 = 0, INT2 = 1, INT1 = 1, INT0 = 0, means that there is no interrupt on channel 0 and channel 3, and there is interrupt on channel 1 and channel 2. 6.3 RESET input The RESET input is an active LOW signal which may be used to recover from a bus fault condition. By asserting this signal LOW for a minimum of tw(rst)L, the PCA9545A/45B/45C resets its registers and I2C-bus state machine and deselects all channels. The RESET input must be connected to VDD through a pull-up resistor. Table 5.

Product data sheet Rev. 9 — 5 May 2014 9 of 32 NXP Semiconductors PCA9545A/45B/45C 4-channel I2C-bus switch with interrupt logic and reset 6.4 Power-on reset When power is applied to VDD, an internal Power-On Reset (POR) holds the PCA9545A/45B/45C in a reset condition until VDD has reached VPOR. At this point, the reset condition is released and the PCA9545A/45B/45C registers and I2C-bus state machine are initialized to their default states (all zeroes) causing all the channels to be deselected. Thereafter, VDD must be lowered below 0.2 V for at least 5 s in order to reset the device. 6.5 Voltage translation The pass gate transistors of the PCA9545A/45B/45C are constructed such that the VDD voltage can be used to limit the maximum voltage that is passed from one I2C-bus to another. Figure 9 shows the voltage characteristics of the pass gate transistors (note that the graph was generated using the data specified in Section 11 “Static characteristics” of this data sheet). In order for the PCA9545A/45B/45C to act as a voltage translator, the Vo(sw) voltage should be equal to, or lower than the lowest bus voltage. For example, if the main bus was running at 5 V, and the downstream buses were 3.3 V and 2.7 V, then Vo(sw) should be equal to or below 2.7 V to clamp the downstream bus voltages effectively. Looking at Figure 9, we see that Vo(sw)(max) is at 2.7 V when the PCA9545A/45B/45C supply voltage is 3.5 V or lower, so the PCA9545A/45B/45C supply voltage could be set to 3.3 V. Pull-up resistors can then be used to bring the bus voltages to their appropriate levels (see Figure 16).

Characteristics of the I2C-bus The I2C-bus is for 2-way, 2-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. 7.1 Bit transfer One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse, as changes in the data line at this time are interpreted as control signals (see Figure 10). 7.2 START and STOP conditions Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the START condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP condition (P) (see Figure 11). Fig 10. Bit transfer Fig 11.

Product data sheet Rev. 9 — 5 May 2014 11 of 32 NXP Semiconductors PCA9545A/45B/45C 4-channel I2C-bus switch with interrupt logic and reset 7.3 System configuration A device generating a message is a ‘transmitter’, a device receiving is the ‘receiver’. The device that controls the message is the ‘master’ and the devices which are controlled by the master are the ‘slaves’ (see Figure 12). 7.4 Acknowledge The number of data bytes transferred between the START and the STOP conditions from transmitter to receiver is not limited. Each byte of 8 bits is followed by one acknowledge bit. The acknowledge bit is a HIGH level put on the bus by the transmitter, whereas the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse; set-up and hold times must be taken into account. A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a STOP condition. Fig 12. System configuration Fig 13.

Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 15.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 15.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • Board specifications, including the board finish, solder masks and vias • Package footprints, including solder thieves and orientation • The moisture sensitivity level of the packages • Package placement • Inspection and repair • Lead-free soldering versus SnPb soldering 15.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities PCA9545A_45B_45C All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 11 and 12 Moisture sensitivity precautions, as indicated on the packing, must be respected at all times. Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 25. Table 11.

General description The LPC3220/30/40/50 embedded microcontrollers were designed for low power, high performance applications. NXP achieved their performance goals using a 90 nanometer process to implement an ARM926EJ-S CPU core with a vector floating point co-processor and a large set of standard peripherals including USB On-The-Go. The LPC3220/30/40/50 operates at CPU frequencies of up to 266 MHz. The NXP implementation uses a ARM926EJ-S CPU core with a Harvard architecture, 5-stage pipeline, and an integral Memory Management Unit (MMU). The MMU provides the virtual memory capabilities needed to support the multi-programming demands of modern operating systems. The ARM926EJ-S also has a hardware based set of DSP instruction extensions, which includes single cycle MAC operations, and hardware based native Jazelle Java Byte-code execution. The NXP implementation has a 32 kB instruction cache and a 32 kB data cache. For low power consumption, the LPC3220/30/40/50 takes advantage of NXP’s advanced technology development to optimize intrinsic power and uses software controlled architectural enhancements to optimize application based power management. The LPC3220/30/40/50 also includes 256 kB of on-chip static RAM, a NAND flash interface, an Ethernet MAC, an LCD controller that supports STN and TFT panels, and an external bus interface that supports SDR and DDR SDRAM as well as static devices. In addition, the LPC3220/30/40/50 includes a USB 2.0 full-speed interface, seven UARTs, two I2C-bus interfaces, two SPI/SSP ports, two I2S-bus interfaces, two single output PWMs, a motor control PWM, six general purpose timers with capture inputs and compare outputs, a Secure Digital (SD) interface, and a 10-bit Analog-to-Digital Converter (ADC) with a touch screen sense option. 2. Features and benefits ARM926EJ-S processor, running at CPU clock speeds up to 266 MHz. Vector Floating Point (VFP) coprocessor. 32 kB instruction cache and 32 kB data cache. Up to 256 kB of Internal SRAM (IRAM). Selectable boot-up from various external devices: NAND flash, SPI memory, USB, UART, or static memory. Multi-layer AHB system that provides a separate bus for each AHB master, including both an instruction and data bus for the CPU, two data busses for the DMA controller, and another bus for the USB controller, one for the LCD, and a final one for the Ethernet MAC. There are no arbitration delays in the system unless two masters attempt to access the same slave at the same time.

There are two special cases for determining supply domain voltages (for details see application note AN10777): a) Ethernet configured in MII mode: VDD_IOD must be the same as VDD_IOB. b) UART 3 when used with hardware flow control or when sharing an RS-232 transceiver with another UART: VDD_IOA must be the same as VDD_IOD.

Product data sheet Rev. 2 — 20 October 2011 24 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7. Functional description 7.1 CPU and subsystems 7.1.1 CPU NXP created the LPC3220/30/40/50 using an ARM926EJ-S CPU core that includes a Harvard architecture and a 5-stage pipeline. To this ARM core, NXP implemented a 32 kB instruction cache, a 32 kB data cache and a Vector Floating Point coprocessor. The ARM926EJ-S core also has an integral Memory Management Unit (MMU) to provide the virtual memory capabilities required to support the multi-programming demands of modern operating systems. The basic ARM926EJ-S core V5TE instruction set includes DSP instruction extensions for native Jazelle Java Byte-code execution in hardware. The LPC3220/30/40/50 operates at CPU frequencies up to 266 MHz. 7.1.2 Vector Floating Point (VFP) coprocessor The LPC3220/30/40/50 includes a VFP co-processor providing full support for single-precision and double-precision add, subtract, multiply, divide, and multiply-accumulate operations at CPU clock speeds. It is compliant with the IEEE 754 standard for binary Floating-Point Arithmetic. This hardware floating point capability makes the microcontroller suitable for advanced motor control and DSP applications. The VFP has 3 separate pipelines for floating-point MAC operations, divide or square root operations, and Load/Store operations. These pipelines operate in parallel and can complete execution out of order. All single-precision instructions execute in one cycle, except the divide and square root instructions. All double-precision multiply and multiply-accumulate instructions take two cycles. The VFP also provides format conversions between floating-point and integer word formats. 7.1.3 Emulation and debugging The LPC3220/30/40/50 supports emulation and debugging via a dedicated JTAG serial port. An Embedded Trace Buffer allows tracing program execution. The dedicated JTAG port allows debugging of all chip features without impact to any pins that may be used in the application. 7.1.3.1 Embedded ICE Standard ARM EmbeddedICE logic provides on-chip debug support. The debugging of the target system requires a host computer running the debugger software and an Embedded ICE protocol converter. The Embedded ICE protocol converter converts the Remote Debug Protocol commands to the JTAG data needed to access the ARM core. The ARM core has a Debug Communication Channel (DCC) function built-in. The debug communication channel allows a program running on the target to communicate with the host debugger or another separate host without stopping the program flow or entering the debug state.

Product data sheet Rev. 2 — 20 October 2011 25 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.1.3.2 Embedded trace buffer The Embedded Trace Module (ETM) is connected directly to the ARM core. It compresses the trace information and exports it through a narrow trace port. An internal Embedded Trace Buffer (ETB) of 2048 24 bits captures the trace information under software debugger control. Data from the ETB is recovered by the debug software through the JTAG port. The trace contains information about when the ARM core switches between states. Instruction shows the flow of execution of the processor and provides a list of all the instructions that were executed. Instruction trace is significantly compressed by only broadcasting branch addresses as well as a set of status signals that indicate the pipeline status on a cycle by cycle basis. For data accesses either data or address or both can be traced. 7.2 AHB matrix The LPC3220/30/40/50 has a multi-layer AHB matrix for inter-block communication. AHB is an ARM defined high-speed bus, which is part of the ARM bus architecture. AHB is a high-bandwidth low-latency bus that supports multi-master arbitration and a bus grant/request mechanism. For systems that have only one (CPU), or two (CPU and DMA) bus masters a simple AHB works well. However, if a system requires multiple bus masters and the CPU needs access to external memory, a single AHB bus can cause a bottleneck. To increase performance, the LPC3220/30/40/50 uses an expanded AHB architecture known as Multi-layer AHB. A Multi-layer AHB replaces the request/grant and arbitration mechanism used in a simple AHB with an interconnect matrix that moves arbitration out toward the slave devices. Thus, if a CPU and a DMA controller want access to the same memory, the interconnect matrix arbitrates between the two when granting access to the memory. This advanced architecture allows simultaneous access by bus masters to different resources with an increase in arbitration complexity. In this architectural implementation, removing guaranteed central arbitration and allowing more than one bus master to be active at the same time provides better overall microcontroller performance. In the LPC3220/30/40/50, the multi-Layer AHB system has a separate bus for each of seven AHB Masters: • CPU data bus • CPU instruction bus • General purpose DMA Master 0 • General purpose DMA Master 1 • Ethernet controller • USB controller • LCD controller There are no arbitration delays unless two masters attempt to access the same slave at the same time.

The APB performs reads and writes to peripheral registers in three peripheral clocks. 7.2.2 FAB Some peripherals are placed on a special bus called FAB that allows faster CPU access to those peripheral functions. A write access to FAB peripherals takes a single AHB clock and a read access to FAB peripherals takes two AHB clocks. 7.3 Physical memory map The physical memory map incorporates several distinct regions, as shown in Figure 3. When an application is running, the CPU interrupt vectors are re-mapped to allow them to reside in on-chip SRAM (IRAM).

After reset, execution always begins from the internal ROM. The bootstrap software first reads the SERVICE input (GPI_1). If SERVICE is LOW, the bootstrap starts a service boot and can download a program over serial link UART 5 to IRAM and transfer execution to the downloaded code. If the SERVICE pin is HIGH, the bootstrap routine jumps to normal boot. The normal boot process first tests SPI memory for boot information if present it uploads the boot code and transfers execution to the uploaded software. If the SPI is not present or no software is loaded, the bootloader will test the EMC Static CS0 memory for the presence of boot code and if present boots from static memory, If this test fails the boot loader will test external NAND flash for boot code and boot if code is present. The boot loader consumes no user memory space because it is in ROM. 7.4.2 On-chip SRAM On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed as 8, 16, or 32 bit memory. The LPC3220/30/40/50 provides 256 kB of internal SRAM. 7.5 External memory interfaces The LPC3220/30/40/50 includes three external memory interfaces, NAND Flash controllers, Secure Digital Memory Controller, and an external memory controller for SDRAM, DDR SDRAM, and Static Memory devices. 7.5.1 NAND flash controllers The LPC3220/30/40/50 includes two NAND flash controllers, one for multi-level cell NAND flash devices and one for single-level cell NAND flash devices. The two NAND flash controllers use the same pins to interface to external NAND flash devices, so only one interface is active at a time. 7.5.1.1 Multi-Level Cell (MLC) NAND flash controller The MLC NAND flash controller interfaces to either multi-level or single-level NAND flash devices. An external NAND flash device is used to allow the bootloader to automatically load a portion of the application code into internal SRAM for execution following reset. The MLC NAND flash controller supports small (528 byte) and large (2114 byte) pages. Programmable NAND timing parameters allow support for a variety of NAND flash devices. A built-in Reed-Solomon encoder/decoder provides error detection and correction capability. A 528 byte data buffer reduces the need for CPU supervision during loading. The MLC NAND flash controller also provides DMA support. LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.

Each of these four peripherals contain an integral DMA controller optimized to support the performance demands of the peripheral. 7.6.1 General Purpose DMA (GPDMA) controller The GPDMA controller allows peripheral-to memory, memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream provides unidirectional serial DMA transfers for a single source and destination. For example, a bidirectional port requires one stream for transmit and one for receive. The source and destination areas can each be either a memory region or a peripheral, and can be accessed through the same AHB master, or one area by each master. The DMA controller supports the following peripheral device transfers. • Secure Digital (SD) Memory interface • High-speed UARTs • I2S0 and I2S1 ports • SPI1 and SPI2 interfaces • SSP0 and SSP1 interfaces • Memory The DMA controls eight DMA channels with hardware prioritization. The DMA controller interfaces to the system via two AHB bus masters, each with a full 32-bit data bus width. DMA operations may be set up for 8-bit, 16-bit, and 32-bit data widths, and can be either big-endian or little-endian. Incrementing or non-incrementing addressing for source and destination are supported, as well as programmable DMA burst size. Scatter or gather DMA is supported through the use of linked lists. This means that the source and destination areas do not have to occupy contiguous areas of memory. 7.6.2 Ethernet MAC The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011.

Product data sheet Rev. 2 — 20 October 2011 34 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.7 System functions To enhance the performance of the LPC3220/30/40/50 incorporates the following system functions, an Interrupt Controller (INTC), a watchdog timer, a millisecond timer, and several power control features. These functions are described in the following sections 7.7.1 Interrupt controller The interrupt controller is comprised of three basic interrupt controller blocks, supporting a total of 73 interrupt sources. Each interrupt source can be individually enabled/disabled and configured for high or low level triggering, or rising or falling edge triggering. Each interrupt may also be steered to either the FIQ or IRQ input of the ARM9. Raw interrupt status and masked interrupt status registers allow versatile condition evaluation. In addition to peripheral functions, each of the six general purpose input/output pins and 12 of the 22 general purpose input pins are connected directly to the interrupt controller. 7.7.2 Watchdog timer The watchdog timer block is clocked by the main peripheral clock, which clocks a 32-bit counter. A match register is compared to the Timer. When configured for watchdog functionality, a match drives the match output low. The match output is gated with an enable signal that gives the opportunity to generate two type of reset signal: one that only resets chip internally, and another that goes through a programmable pulse generator before it goes to the external pin RESOUT and to the internal chip reset. 7.7.2.1 Features • Programmable 32-bit timer. • Internally resets the device if not periodically reloaded. • Flag to indicate that a watchdog reset has occurred. • Programmable watchdog pulse output on RESOUT pin. • Can be used as a standard timer if watchdog is not used. • Pause control to stop counting when core is in debug state. 7.7.3 Millisecond timer The millisecond timer is clocked by 32 kHz RTC clock, so a prescaler is not needed to obtain a lower count rate. The millisecond timer includes three match registers that are compared to the Timer/Counter value. A match can generate an interrupt and the cause the Timer/Counter either continue to run, stop, or be reset. 7.7.3.1 Features • 32-bit Timer/Counter, running from the 32 kHz RTC clock. • Counter or Timer operation. • Three 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Pause control to stop counting when core is in debug state.

Product data sheet Rev. 2 — 20 October 2011 35 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.7.4 Clocking and power control features 7.7.4.1 Clocking Clocking in the LPC3220/30/40/50 is designed to be versatile, so that system and peripheral requirements may be met, while allowing optimization of power consumption. Clocks to most functions may be turned off if not needed and some peripherals do this automatically. The LPC3220/30/40/50 supports three operational modes, two of which are specifically designed to reduce power consumption. The modes are: Run mode, Direct run mode, and Stop mode.These three operational modes give control over processing speed and power consumption. In addition, clock rates to different functional blocks may be changed by switching clock sources, changing PLL values, or altering clock divider configurations. This allows a trade-off of power versus processing speed based on application requirements. 7.7.4.2 Crystal oscillator The main oscillator is the basis for the clocks most chip functions use by default. Optionally, many functions can be clocked instead by the output of a PLL (with a fixed 397x rate multiplication) which runs from the RTC oscillator. In this mode, the main oscillator may be turned off unless the USB interface is enabled. If a SYSCLK frequency other than 13 MHz is required in the application, or if the USB block is not used, the main oscillator may be used with a frequency of between 1 MHz and 20 MHz. 7.7.4.3 PLLs The LPC3220/30/40/50 includes three PLLs: The 397x PLL allows boosting the RTC frequency to 13.008896 MHz for use as the primary system clock. The USB PLL provides the 48 MHz clock required by the USB block, and the HCLK PLL provides the basis for the CPU clock, the AHB bus clock, and the main peripheral clock. The 397x PLL multiplies the 32768 Hz RTC clock by 397 to obtain a 13.008896 MHz clock. The 397x PLL is designed for low power operation and low jitter. This PLL requires an external RC loop filter for proper operation. The HCLK PLL accepts an input clock from either the main oscillator or the output of the 397x PLL. The USB PLL only accepts an input clock from the main oscillator.The USB input clock runs through a divide-by-N pre-divider before entering the USB PLL. The input to the HCLK and USB PLLs may initially be divided down by a pre-divider value ‘N’, which may have the values 1, 2, 3, or 4. This pre-divider can allow a greater number of possibilities for the output frequency. Following the PLL input divider is the PLL multiplier. This can multiply the pre-divider output by a value ‘M’, in the range of 1 through 256. The resulting frequency must be in the range of 156 MHz to 320 MHz. The multiplier works by dividing the output of a Current Controlled Oscillator (CCO) by the value of M, then using a phase detector to compare the divided CCO output to the pre-divider output. The error value is used to adjust the CCO frequency. At the PLL output, there is a post-divider that can be used to bring the CCO frequency down to the desired PLL output frequency. The post-divider value can divide the CCO output by 1, 2, 4, 8, or 16. The post-divider can also be bypassed, allowing the PLL CCO LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved. Product data sheet Rev. 2 — 20 October 2011 36 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers output to be used directly. The maximum PLL output frequency supported by the CPU is 266 MHz. The only output frequency supported by the USB PLL is 48 MHz, and the clock has strict requirements for nominal frequency (500 ppm) and jitter (500 ps). 7.7.4.4 Power control modes The LPC3220/30/40/50 supports three operational modes, two of which are specifically designed to reduce power consumption. The modes are: Run mode, Direct Run mode, and Stop mode. Run mode is the normal operating mode for applications that require the CPU, AHB bus, or any peripheral function other than the USB block to run faster than the main oscillator frequency. In Run mode, the CPU can run at up to 266 MHz and the AHB bus can run at up to 133 MHz. Direct Run mode allows reducing the CPU and AHB bus rates in order to save power. Direct Run mode can also be the normal operating mode for applications that do not require the CPU, AHB bus, or any peripheral function other than the USB block to run faster than the main oscillator frequency. Direct Run mode is the default mode following chip reset. Stop mode causes all CPU and AHB operation to cease, and stops clocks to peripherals other than the USB block. 7.7.4.5 Reset Reset is accomplished by an active LOW signal on the RESET input pin. A reset pulse with a minimum width of 10 main oscillator clocks after the oscillator is stable is required to guarantee a valid chip reset. At power-up, 10 milliseconds should be allowed for the oscillator to start up and stabilize after VDD reaches operational voltage. An internal reset with a minimum duration of 10 clock pulses will also be applied if the watchdog timer generates an internal device reset. The RESET pin is located in the RTC power domain. This means that the RTC power must be present for an external reset to have any effect. The RTC power domain nominally runs from 1.2 V, but the RESET pin can be driven as high as 1.95 V. 7.8 Communication peripheral interfaces In addition to the Ethernet MAC and USB interfaces there are many more serial communication peripheral interfaces available on the LPC3220/30/40/50. Here is a list of the serial communication interfaces: • Seven UARTs; four standard UARTs and three high-speed UARTs • Two SPI serial I/O controllers • Two SSP serial I/O controllers • Two I2C serial I/O controllers • Two I2S audio controllers A short functional description of each of these peripherals is provided in the following sections.

Product data sheet Rev. 2 — 20 October 2011 38 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers Only a single master and a single slave can communicate on the interface during a given data transfer. During a data transfer the master always sends a byte of data to the slave, and the slave always sends a byte of data to the master. The SPI implementation on the LPC3220/30/40/50 does not support operation as a slave. 7.8.2.1 Features • Supports slaves compatible with SPI modes 0 to 3. • Half duplex synchronous transfers. • DMA support for data transmit and receive. • 1-bit to 16-bit word length. • Choice of LSB or MSB first data transmission. • 64 16-bit input or output FIFO. • Bit rates up to 52 Mbit/s. • Busy input function. • DMA time out interrupt to allow detection of end of reception when using DMA. • Timed interrupt to facilitate emptying the FIFO at the end of a transmission. • SPI clock and data pins may be used as general purpose pins if the SPI is not used. • Slave selects can be supported using GPO or GPIO pins 7.8.3 SSP serial I/O controller The LPC3220/30/40/50 contains two SSP controllers. The SSP controller is capable of operation on a SPI, 4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the slave and from the slave to the master. In practice, often only one of these data flows carries meaningful data. 7.8.3.1 Features • Compatible with Motorola SPI, 4-wire TI SSI, and National Semiconductor Microwire buses • Synchronous serial communication • Master or slave operation • 8-frame FIFOs for both transmit and receive • 4-bit to 16-bit frame • Maximum SPI bus data bit rate of 1⁄2 (Master mode) and 1⁄2 (Slave mode) of the input clock rate • DMA transfers supported by GPDMA 7.8.4 I2C-bus serial I/O controller There are two I2C-bus interfaces in the LPC32x0 family of controllers. These I2C blocks can be configured as a master, multi-master or slave supporting up to 400 kHz. The I2C blocks also support 7 or 10 bit addressing. Each has a four word FIFO for both transmit and receive. An interrupt signal is available from each block.

Product data sheet Rev. 2 — 20 October 2011 39 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers There is a separate slave transmit FIFO. The slave transmit FIFO (TXS) and its level are only available when the controller is configured as a Master/Slave device and is operating in a multi-master environment. Separate TX FIFOs are needed in a multi-master because a controller might have a message queued for transmission when an external master addresses it to be come a slave-transmitter, a second source of data is needed. Note that the I2C clock must be enabled in the I2CCLK_CTRL register before using the I2C. The I2C clock can be disabled between communications, if used as a single master I2C-bus interface, software has full control of when I2C communication is taking place on the bus. 7.8.4.1 Features • The two I2C-bus blocks are standard I2C-bus compliant interfaces that may be used in Single-master, Multi-master or Slave modes. • Programmable clock to allow adjustment of I2C-bus transfer rates. • Bidirectional data transfer. • Serial clock synchronization allows devices with different bit rates to communicate via one serial bus. • Serial clock synchronization can be used as a handshake mechanism to suspend and resume serial transfer. 7.8.5 I2S-bus audio controller The I2S-bus provides a standard communication interface for digital audio applications The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line, and one word select signal. Each I2S connection can act as a master or a slave. The master connection determines the frequency of the clock line and all other slaves are driven by this clock source. The two I2S-bus interfaces on the LPC3220/30/40/50 provides a separate transmit and receive channel, providing a total of two transmit channels and two receive channels. Each I2S channel supports monaural or stereo formatted data. 7.8.5.1 Features • The interface has separate input/output channels each of which can operate in master or slave mode. • Capable of handling 8-bit, 16-bit, and 32-bit word sizes. • Mono and stereo audio data supported. • Supports standard sampling frequencies (8 kHz, 11.025 kHz, 16 kHz, 22.05 kHz, 32 kHz, 44.1 kHz, 48 kHz, 96 kHz). • Word select period can be configured in master mode (separately for I2S input and output). • Two eight-word FIFO data buffers are provided, one for transmit and one for receive. • Generates interrupt requests when buffer levels cross a programmable boundary. • Two DMA requests, controlled by programmable buffer levels. These are connected to the GPDMA block. • Controls include reset, stop, and mute options separately for I2S input and I2S output.

Here is a list of the general purpose peripherals. • GPI/O • Keyboard scanner • Touch screen controller and 10-bit Analog-to-Digital-Converter • Real-time clock • High-speed timer • Four general purpose 32-bit timer/external event counters • Two simple PWMs • One motor control PWM A short functional description of each of these peripherals is provided in the following sections. 7.9.1 General purpose parallel I/O Some device pins that are not dedicated to a specific peripheral function have been designed to be general purpose inputs, outputs, or input/outputs. Also, some pins may be configured either as a specific peripheral function or a general purpose input, output, or input/output. A total of 51 pins can potentially be used as general purpose input/outputs, 24 as general purpose outputs, and 22 as general purpose inputs. GPIO pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of GPIO and GPO outputs controlled by that register simultaneously. The value of the output register for standard GPIOs and GPO pins may be read back, as well as the current actual state of the port pins. In addition to GPIO pins on port 0, port 1, and port 2, there are 22 GPI, 24 GPO, and six GPIO pins. When the SDRAM bus is configured for 16 data bits, 13 of the remaining SDRAM data pins may be used as GPIOs. 7.9.1.1 Features • Bit-level set and clear registers allow a single instruction set or clear of any number of bits in one port. • A single register selects direction for pins that support both input and output modes. • Direction control of individual bits. • For input/output pins, both the programmed output state and the actual pin state can be read. • There are a total of 12 general purpose inputs, 24 general purpose outputs, and six general purpose input/outputs. • Additionally, 13 SDRAM data lines may be used as GPIOs if a 16-bit SDRAM interface is used (rather than a 32-bit interface).

Product data sheet Rev. 2 — 20 October 2011 41 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers 7.9.2 Keyboard scanner The keyboard scanner function can automatically scan a keyboard of up to 64 keys in an 8 8 matrix. In operation, the keyboard scanner’s internal state machine will normally be in an idle state, with all KEY_ROWn pins set high, waiting for a change in the column inputs to indicate that one or more keys have been pressed. When a keypress is detected, the matrix is scanned by setting one output pin high at a time and reading the column inputs. After de-bouncing, the keypad state is stored and an interrupt is generated. The keypad is then continuously scanned waiting for ‘extra key pressed’ or ‘key released’. Any new keypad state is scanned and stored into the matrix registers followed by a new interrupt request to the interrupt controller. It is possible to detect and separate up to 64 multiple keys pressed. 7.9.2.1 Features • Supports up to 64 keys in 8 8 matrix. • Programmable de-bounce period. • A key press can wake up the CPU from Stop mode. 7.9.3 Touch screen controller and 10-bit ADC The LPC3220/30/40/50 microcontrollers includes Touch Screen Controller (TSC) hardware, which automatically measures and determines the X and Y coordinates where a touch screen is pressed. In addition, the TSC can measure an analog input signal on the AUX_IN pin. Optionally, the TSC can operate as an Analog-to-Digital Converter (ADC). The ADC supports three channels and uses 10-bit successive approximation to produce results with a resolution of 10 bits in 11 clock cycles. The analog portion of the ADC has its own power supply to enhance the low noise characteristics of the converter. This voltage is only supplied internally when the core has voltage. However, the ADC block is not affected by any difference in ramp-up time for VDD_AD and VDD_CORE voltage supplies. 7.9.3.1 Features • Measurement range of 0 V to VDD_AD (nominally 3.3 V). • Low-noise ADC. • 10-bit resolution. • Three input channels. • Uses 32 kHz RTC clock or peripheral clock. 7.9.4 Real-Time Clock (RTC) and battery RAM The RTC runs at 32768 Hz using a very low power oscillator. The RTC counts seconds and can generate alarm interrupts that can wake up the device from Stop mode. The RTC clock can also clock the 397x PLL, the Millisecond Timer, the ADC, the Keyboard Scanner and the PWMs. The RTC up-counter value represents a number of seconds elapsed since second 0, which is an application determined time. The RTC counter will reach maximum value after about 136 years. The RTC down-counter is initiated with all ones.

Product data sheet Rev. 2 — 20 October 2011 42 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers Two 32-bit match registers are readable and writable by the processor. A match will result in an interrupt provided that the interrupt is enabled. The ONSW output pin can also be triggered by a match event and cause an external power supply to turn on all of the operating voltages, as a way to startup after power has been removed. The RTC block is implemented in a separate voltage domain. The block is supplied via a separate supply pin from a battery or other power source. The RTC block also contains 32 words (128 bytes) of very low voltage SRAM. This SRAM is able to hold its contents down to the minimum RTC operating voltage. 7.9.4.1 Features • Measures the passage of time in seconds. • 32-bit up and down seconds counters. • Ultra-low power design to support battery powered systems. • Dedicated 32 kHz oscillator. • An output pin is included to assist in waking up when the chip has had power removed to all functions except the RTC. • Two 32-bit match registers with interrupt option. • 32 words (128 bytes) of very low voltage SRAM. • The RTC and battery RAM power have an independent power domain and dedicated supply pins, which can be powered from a battery or power supply. Remark: The LPC3220/30/40/50 will run at voltages down to 0.9 V at frequencies below 14 MHz. However, the ARM core cannot access the RTC registers and battery RAM when the core supply voltage is at 0.9 V and the RTC supply is at 1.2 V. 7.9.5 Enhanced 32-bit timers/external event counters The LPC3220/30/40/50 includes six 32-bit Timer/Counters. The Timer/Counter is designed to count cycles of the system derived clock or an externally-supplied clock. It can optionally generate interrupts or perform other actions at specified timer values, based on four match registers. The Timer/Counter also includes four capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. 7.9.5.1 Features • A 32-bit Timer/Counter with a programmable 32-bit pre-scaler. • Counter or Timer operation. • Up to four 32-bit capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event may also optionally generate an interrupt. • Four 32-bit match registers that allow: – continuous operation with optional interrupt generation on match – stop timer on match with optional interrupt generation – reset timer on match with optional interrupt generation • Up to four external outputs corresponding to match registers, with the following capabilities: LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011.

The clock is first divided down in a 16-bit programmable pre-scale counter which clocks a 32-bit timer/counter. The high-speed timer includes three match registers that are compared to the timer/counter value. A match can generate an interrupt and cause the timer/counter to either continue to run, stop, or be reset. The high-speed timer also includes two capture registers that can take a snapshot of the timer/counter value when an input signal transitions. A capture event may also generate an interrupt. 7.9.6.1 Features • 32-bit timer/counter with programmable 16-bit pre-scaler. • Counter or timer operation. • Two 32-bit capture registers. • Three 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Pause control to stop counting when core is in debug state. 7.9.7 Pulse Width Modulators (PWMs) The LPC3220/30/40/50 provides two simple PWMs. They are clocked separately by either the main peripheral clock or the 32 kHz RTC clock. Both PWMs have a duty cycle programmable in 255 steps. 7.9.7.1 Features • Clocked by the main peripheral clock or the 32 kHz RTC clock. • Programmable 4-bit pre-scaler. • Duty cycle programmable in 255 steps. • Output frequency up to 50 kHz when using a 13 MHz peripheral clock. 7.9.8 Motor control pulse width modulator The Motor Control PWM (MCPWM) provides a set of features for three-phase AC and DC motor control applications in a single peripheral. The MCPWM can also be configured for use in other generalized timing, counting, capture, and compare applications. 7.9.8.1 Features • 32-bit timer • 32-bit period register LPC3220_30_40_50 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved. Product data sheet Rev. 2 — 20 October 2011 44 of 79 NXP Semiconductors LPC3220/30/40/50 16/32-bit ARM microcontrollers • 32-bit pulse-width (match) register • 10-bit dead-time register and an associated 10-bit dead-time counter • 32-bit capture register • Two PWM (match) outputs (pins MCOA0/1/2 and MCOB0/1/2) with opposite polarities • Period interrupt, pulse-width interrupt, and capture interrupt 8. Basic architecture The LPC3220/30/40/50 is a general purpose ARM926EJ-S 32-bit microprocessor with a 32 kB instruction cache and a 32 kB data cache. The microcontroller offers high performance and very low power consumption. The ARM architecture is based on RISC principles, which results in the instruction set and related decode mechanism being much simpler than equivalent micro programmed CISCs. This simplicity results in a high instruction throughput and impressive real-time interrupt response from a small and cost-effective processor core. The ARM926EJ-S core employs a 5-stage pipeline so processing and memory system accesses can occur continuously. At any one point in time, several operations are in progress: subsequent instruction fetch, next instruction decode, instruction execution, memory access, and write-back. The combination of architectural enhancements gives the ARM9 about 30 % better performance than an ARM7 running at the same clock rate: • Approximately 1.3 clocks per instruction for the ARM926EJ-S compared to 1.9 clocks per instruction for ARM7TDMI. • Approximately 1.1 Dhrystone MIPS/MHz for the ARM926EJ-S compared to 0.9 Dhrystone MIPS/MHz for ARM7TDMI. The ARM926EJ-S processor also employs an operational state known as Thumb, which makes it ideally suited to high-volume applications with memory restrictions, or applications where code density is an issue. The key idea behind Thumb state is the use of a super-reduced instruction set. Essentially, the ARM926EJ-S processor core has two instruction sets: 1. The standard 32-bit ARM set 2. The 16-bit Thumb set The Thumb set’s smaller 16-bit instruction length allows it to approach twice the density of standard ARM code while retaining many of ARM’s 32-bit performance advantage over a traditional 16-bit processor using 16-bit registers. This is possible because Thumb code operates using the same 32-bit register set as ARM code. Thumb code size is up to 65 % smaller than ARM code size, and 160 % of the performance of an equivalent ARM processor connected to a 16-bit memory system. Additionally, the ARM926EJ-S core includes enhanced DSP instructions and multiplier, as well as an enhanced 32-bit MAC block.

An internal circuit ensures that the system correctly powers up in the absence of core power. During IO power-up this circuit takes care that the system is powered in a defined mode. The same is valid for core power-down. 10.3 Power consumption per peripheral [1] All three Ethernet clocks are in enabled in the MAC_CLK_CTRL register (see LPC32x0 User manual). Fig 4.

MMU and I-cache/D-cache are enabled. The VFP is turned on but not used. I2S-interface (channel 1), LCD, SLC NAND controller, I2C1-bus, SD card, touchscreen ADC, and UART 3 are turned on. All other peripherals are turned off. The AHB clock HCLK is identical to the core clock for frequencies up to 133 MHz, which is the maximum allowed HCLK frequency. For higher core frequencies, the HCLK PLL output must be divided by 2 to obtain an HCLK frequency lower than or equal to 133 MHz resulting in correspondingly lower power consumption by the AHB peripherals. Conditions: Tamb = 25 C; VDD_CORE = 1.2 V for core frequencies 208 MHz; VDD_CORE = 1.35 V for core frequencies > 208 MHz; VDD(IO) = 1.8 V.

[2] The ADC is monotonic; there are no missing codes. [3] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 6. [4] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 6. [5] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the ideal curve. See Figure 6. [6] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset error, and the straight line which fits the ideal transfer curve. See Figure 6. [7] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated ADC and the ideal transfer curve. See Figure 6.

Product data sheet Rev. 4.3 — 22 April 2014 8 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 7.2 Pin description The pin description consists of two parts showing pin functions that are fixed to a certain package pin (see Table 4) and showing pin functions that can be assigned to any pin on the package through the switch matrix (see Table 5). The pin description table in Table 4 shows the pin functions that are fixed to specific pins on each package. These fixed-pin functions are selectable between GPIO and the comparator inputs, SWD, RESET, and the XTAL pins. By default, the GPIO function is selected except on pins PIO0_2, PIO0_3, and PIO0_5. JTAG functions are available in boundary scan mode only. Table 5 shows the the I2C, USART, SPI, and SCT pin functions, which can be assigned through the switch matrix to any pin that is not power or ground in place of the pin’s fixed functions. The following exceptions apply: For full I2C-bus compatibility, assign the I2C functions to the open-drain pins PIO0_11 and PIO0_10. Do not assign more than one output to any pin. However, more than one input can be assigned to a pin. Once any function is assigned to a pin, the pin’s GPIO functionality is disabled. Pin PIO0_4 triggers a wake-up from Deep power-down mode. If you need to wake up from Deep power-down mode via an external pin, do not assign any movable function to this pin. The JTAG functions TDO, TDI, TCK, TMS, and TRST are selected on pins PIO0_0 to PIO0_4 by hardware when the part is in boundary scan mode. Table 4.

SWDIO is enabled by default on this pin. In boundary scan mode: TMS (Test Mode Select). I/O - PIO0_2 — General purpose digital input/output pin. SWCLK/PIO0_3/ TCK 6 5 5 3 [2] I/O I; PU SWCLK — Serial Wire Clock. SWCLK is enabled by default on this pin. In boundary scan mode: TCK (Test Clock). I/O - PIO0_3 — General purpose digital input/output pin. PIO0_4/WAKEUP/ TRST 5 4 4 2 [6] I/O I; PU PIO0_4 — General purpose digital input/output pin. In ISP mode, this is the USART0 transmit pin U0_TXD. In boundary scan mode: TRST (Test Reset). This pin triggers a wake-up from Deep power-down mode. If you need to wake up from Deep power-down mode via an external pin, do not assign any movable function to this pin. This pin should be pulled HIGH externally before entering Deep power-down mode.

All rights reserved. Product data sheet Rev. 4.3 — 22 April 2014 17 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 8.9 Switch Matrix (SWM) The switch matrix controls the function of each digital or mixed analog/digital pin in a highly flexible way by allowing to connect many functions like the USART, SPI, SCT, and I2C functions to any pin that is not power or ground. These functions are called movable functions and are listed in Table 5. Functions that need specialized pads like the oscillator pins XTALIN and XTALOUT can be enabled or disabled through the switch matrix. These functions are called fixed-pin functions and cannot move to other pins. The fixed-pin functions are listed in Table 4. If a fixed-pin function is disabled, any other movable function can be assigned to this pin. 8.10 Fast General-Purpose parallel I/O (GPIO) Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs can be set or cleared in one write operation. LPC81xM use accelerated GPIO functions: • GPIO registers are located on the ARM Cortex M0+ IO bus for fastest possible single-cycle I/O timing, allowing GPIO toggling with rates of up to 15 MHz.

Product data sheet Rev. 4.3 — 22 April 2014 18 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller • An entire port value can be written in one instruction. • Mask, set, and clear operations are supported for the entire port. All GPIO port pins are fixed-pin functions that are enabled or disabled on the pins by the switch matrix. Therefore each GPIO port pin is assigned to one specific pin and cannot be moved to another pin. Except for pins SWDIO/PIO0_2, SWCLK/PIO0_3, and RESET/PIO0_5, the switch matrix enables the GPIO port pin function by default. 8.10.1 Features • Bit level port registers allow a single instruction to set and clear any number of bits in one write operation. • Direction control of individual bits. • All I/O default to inputs with internal pull-up resistors enabled after reset - except for the I2C-bus true open-drain pins PIO0_2 and PIO0_3. • Pull-up/pull-down configuration, repeater, and open-drain modes can be programmed through the IOCON block for each GPIO pin (see Figure 8). • 8.11 Pin interrupt/pattern match engine The pin interrupt block configures up to eight pins from all digital pins for providing eight external interrupts connected to the NVIC. The pattern match engine can be used, in conjunction with software, to create complex state machines based on pin inputs. Any digital pin, independently of the function selected through the switch matrix, can be configured through the SYSCON block as input to the pin interrupt or pattern match engine. The registers that control the pin interrupt or pattern match engine are located on the IO+ bus for fast single-cycle access. 8.11.1 Features • Pin interrupts – Up to eight pins can be selected from all digital pins as edge- or level-sensitive interrupt requests. Each request creates a separate interrupt in the NVIC. – Edge-sensitive interrupt pins can interrupt on rising or falling edges or both. – Level-sensitive interrupt pins can be HIGH- or LOW-active. – Pin interrupts can wake up the LPC81xM from sleep mode, deep-sleep mode, and power-down mode. • Pin interrupt pattern match engine – Up to eight pins can be selected from all digital pins to contribute to a boolean expression. The boolean expression consists of specified levels and/or transitions on various combinations of these pins. – Each minterm (product term) comprising the specified boolean expression can generate its own, dedicated interrupt request. – Any occurrence of a pattern match can be programmed to also generate an RXEV notification to the ARM CPU. The RXEV signal can be connected to a pin. LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

USART2 is available on parts LPC812M101JDH16 and LPC812M101JDH20 only. All USART functions are movable functions and are assigned to pins through the switch matrix. 8.12.1 Features • Maximum bit rates of 1.875 Mbit/s in asynchronous mode and 10 Mbit/s in synchronous mode for USART functions connected to all digital pins except PIO0_10 and PIO0_11. • 7, 8, or 9 data bits and 1 or 2 stop bits • Synchronous mode with master or slave operation.

Software flow control can be performed using Delta CTS detect, Transmit Disable control, and any GPIO as an RTS output. • Received data and status can optionally be read from a single register • Break generation and detection. • Receive data is 2 of 3 sample "voting". Status flag set when one sample differs. • Built-in Baud Rate Generator. • A fractional rate divider is shared among all UARTs. • Interrupts available for Receiver Ready, Transmitter Ready, Receiver Idle, change in receiver break detect, Framing error, Parity error, Overrun, Underrun, Delta CTS detect, and receiver sample noise detected. • Separate data and flow control loopback modes for testing. • Supported by on-chip ROM API. 8.13 SPI0/1 Remark: SPI0 is available on all LPC800 parts.

Product data sheet Rev. 4.3 — 22 April 2014 20 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller • Data frames of 1 to 16 bits supported directly. Larger frames supported by software. • Master and slave operation. • Data can be transmitted to a slave without the need to read incoming data. This can be useful while setting up an SPI memory. • Control information can optionally be written along with data. This allows very versatile operation, including “any length” frames. • One Slave Select input/output with selectable polarity and flexible usage. Remark: Texas Instruments SSI and National Microwire modes are not supported. 8.14 I2C-bus interface The I2C-bus is bidirectional for inter-IC control using only two wires: a serial clock line (SCL) and a serial data line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the capability to both receive and send information (such as memory). Transmitters and/or receivers can operate in either master or slave mode, depending on whether the chip has to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be controlled by more than one bus master connected to it. The I2C-bus functions are movable functions and can be assigned through the switch matrix to any pin. However, only the true open-drain PIO0_10 and PIO0_11 provide the electrical characteristics to support the full I2C-bus specification (see Ref. 1). 8.14.1 Features • Supports standard and fast mode with data rates of up to 400 kbit/s. • Independent Master, Slave, and Monitor functions. • Supports both Multi-master and Multi-master with Slave functions. • Multiple I2C slave addresses supported in hardware. • One slave address can be selectively qualified with a bit mask or an address range in order to respond to multiple I2C bus addresses. • 10-bit addressing supported with software assist. • Supports SMBus. • Supported by on-chip ROM API. • If the I2C functions are connected to the true open-drain pins (PIO0_10 and PIO0_11), the I2C supports the full I2C-bus specification: – Fail-safe operation: When the power to an I2C-bus device is switched off, the SDA and SCL pins connected to the I2C-bus are floating and do not disturb the bus. – Supports Fast-mode Plus with bit rates up to 1 Mbit/s. 8.15 State-Configurable Timer/PWM (SCTimer/PWM) The state configurable timer (SCTimer/PWM or SCT) can perform basic 16-bit and 32-bit timer/counter functions with match outputs and external and internal capture inputs. In addition, the SCTimer/PWM can employ up to two different programmable states, which can change under the control of events, to provide complex timing patterns.

Product data sheet Rev. 4.3 — 22 April 2014 22 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller • Optional warning interrupt can be generated at a programmable time prior to watchdog time-out. • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. • Incorrect feed sequence causes reset or interrupt if enabled. • Flag to indicate watchdog reset. • Programmable 24-bit timer with internal prescaler. • Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 224 4) in multiples of Tcy(WDCLK) 4. • The Watchdog Clock (WDCLK)is generated by a the dedicated watchdog oscillator (WDOSC). 8.18 Self Wake-up Timer (WKT) The self wake-up timer is a 32-bit, loadable down-counter. Writing any non-zero value to this timer automatically enables the counter and launches a count-down sequence. When the counter is used as a wake-up timer, this write can occur just prior to entering a reduced power mode. 8.18.1 Features • 32-bit loadable down-counter. Counter starts automatically when a count value is loaded. Time-out generates an interrupt/wake up request. • The WKT resides in a separate, always-on power domain. • The WKT supports two clock sources: the low-power oscillator and the IRC. The low-power oscillator is located in the always-on power domain, so it can be used as the clock source in Deep power-down mode. • The WKT can be used for waking up the part from any reduced power mode, including Deep power-down mode, or for general-purpose timing. 8.19 Analog comparator (ACMP) The analog comparator with selectable hysteresis can compare voltage levels on external pins and internal voltages. After power-up and after switching the input channels of the comparator, the output of the voltage ladder must be allowed to settle to its stable value before it can be used as a comparator reference input. Settling times are given in Table 22. The analog comparator output is a movable function and is assigned to a pin through the switch matrix. The comparator inputs and the voltage reference are enabled or disabled on pins PIO0_0 and PIO0_1 through the switch matrix.

Following reset, the LPC81xM will operate from the IRC until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 10 for an overview of the LPC81xM clock generation. 8.20.1.1 Internal RC Oscillator (IRC) The IRC may be used as the clock source for the WWDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1.5 % accuracy over the entire voltage and temperature range. The IRC can be used as a clock source for the CPU with or without using the PLL. The IRC frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. Upon power-up or any chip reset, the LPC81xM use the IRC as the clock source. Software may later switch to one of the other available clock sources. 8.20.1.2 Crystal Oscillator (SysOsc) The crystal oscillator can be used as the clock source for the CPU, with or without using the PLL. The SysOsc operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. 8.20.1.3 Internal Low-power Oscillator and Watchdog Oscillator (WDOsc) The nominal frequency of the WDOsc is programmable between 9.4 kHz and 2.3 MHz. The frequency spread over silicon process variations is 40%. The WDOsc is a dedicated oscillator for the windowed WWDT. The internal low-power 10 kHz ( 40% accuracy) oscillator serves a the clock input to the WKT. This oscillator can be configured to run in all low power modes. 8.20.2 Clock input An external clock source can be supplied on the selected CLKIN pin. When selecting a clock signal for the CLKIN pin, follow the specifications for digital I/O pins in Table 9 “Static characteristics” and Table 15 “Dynamic characteristics: I/O pins[1]”. An 1.8 V external clock source can be supplied on the XTALIN pins to the system oscillator limiting the voltage of this signal ((see Section 14.2). The maximum frequency for both clock signals is 25 MHz. 8.20.3 System PLL The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency.

Product data sheet Rev. 4.3 — 22 April 2014 26 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is nominally 100 s. 8.20.4 Clock output The LPC81xM features a clock output function that routes the IRC, the SysOsc, the watchdog oscillator, or the main clock to the CLKOUT function. The CLKOUT function can be connected to any digital pin through the switch matrix. 8.20.5 Wake-up process The LPC81xM begin operation at power-up by using the IRC as the clock source. This allows chip operation to resume quickly. If the SysOsc, the external clock source, or the PLL is needed by the application, software must enable these features and wait for them to stabilize before they are used as a clock source. 8.20.6 Power control The LPC81xM supports the ARM Cortex-M0 Sleep mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals, allowing to fine-tune power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Selected peripherals have their own clock divider which provides even better power control. 8.20.6.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through simple calls to the power profile API. The API is accessible through the on-chip ROM. The power configuration routine configures the LPC81xM for one of the following power modes: • Default mode corresponding to power configuration after reset. • CPU performance mode corresponding to optimized processing capability. • Efficiency mode corresponding to optimized balance of current consumption and CPU performance. • Low-current mode corresponding to lowest power consumption. In addition, the power profile includes routines to select the optimal PLL settings for a given system clock and PLL input clock. 8.20.6.2 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core.

Product data sheet Rev. 4.3 — 22 April 2014 27 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 8.20.6.3 Deep-sleep mode In Deep-sleep mode, the LPC81xM is in Sleep-mode and all peripheral clocks and all clock sources are off except for the IRC and watchdog oscillator or low-power oscillator if selected. The IRC output is disabled. In addition all analog blocks are shut down and the flash is in stand-by mode. In Deep-sleep mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC81xM can wake up from Deep-sleep mode via a reset, digital pins selected as inputs to the pin interrupt block, a watchdog timer interrupt, or an interrupt from the USART (if the USART is configured in synchronous slave mode), the SPI, or the I2C blocks (in slave mode). Any interrupt used for waking up from Deep-sleep mode must be enabled in one of the SYSCON wake-up enable registers and the NVIC. Deep-sleep mode saves power and allows for short wake-up times. 8.20.6.4 Power-down mode In Power-down mode, the LPC81xM is in Sleep-mode and all peripheral clocks and all clock sources are off except for watchdog oscillator or low-power oscillator if selected. In addition all analog blocks and the flash are shut down. In Power-down mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC81xM can wake up from Power-down mode via a reset, digital pins selected as inputs to the pin interrupt block, a watchdog timer interrupt, or an interrupt from the USART (if the USART is configured in synchronous slave mode), the SPI, or the I2C blocks (in slave mode). Any interrupt used for waking up from Power-down mode must be enabled in one of the SYSCON wake-up enable registers and the NVIC. Power-down mode reduces power consumption compared to Deep-sleep mode at the expense of longer wake-up times. 8.20.6.5 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip except for the WAKEUP pin and the self wake-up timer if enabled. Four general-purpose registers are available to store information during Deep power-down mode. The LPC81xM can wake up from Deep power-down mode via the WAKEUP pin, or without an external signal by using the time-out of the self wake-up timer (see Section 8.18). The LPC81xM can be prevented from entering Deep power-down mode by setting a lock bit in the PMU block. Locking out Deep power-down mode enables the application to keep the watchdog timer or the BOD running at all times.

Product data sheet Rev. 4.3 — 22 April 2014 28 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller When entering Deep power-down mode, an external pull-up resistor is required on the WAKEUP pin to hold it HIGH. Pull the RESET pin HIGH to prevent it from floating while in Deep power-down mode. 8.21 System control 8.21.1 Reset Reset has four sources on the LPC81xM: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller. A LOW-going pulse as short as 50 ns resets the part. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. In Deep power-down mode, an external pull-up resistor is required on the RESET pin. 8.21.2 Brownout detection The LPC81xM includes up to four levels for monitoring the voltage on the VDD pin. If this voltage falls below one of the selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC to cause a CPU interrupt. Alternatively, software can monitor the signal by reading a dedicated status register. Four threshold levels can be selected to cause a forced reset of the chip. Fig 11.

Product data sheet Rev. 4.3 — 22 April 2014 29 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 8.21.3 Code security (Code Read Protection - CRP) CRP provides different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) and In-System Programming (ISP) can be restricted. Programming a specific pattern into a dedicated flash location invokes CRP. IAP commands are not affected by the CRP. In addition, ISP entry via the ISP entry pin can be disabled without enabling CRP. For details, see the LPC800 user manual. There are three levels of Code Read Protection: 1. CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors cannot be erased. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected, fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using the ISP entry pin as well. If necessary, the application must provide a flash update mechanism using IAP calls or using a call to the reinvoke ISP command to enable flash update via the USART. In addition to the three CRP levels, sampling of the ISP entry pin for valid user code can be disabled. For details, see the LPC800 user manual. 8.21.4 APB interface The APB peripherals are located on one APB bus. 8.21.5 AHBLite The AHBLite connects the CPU bus of the ARM Cortex-M0+ to the flash memory, the main static RAM, the CRC, and the ROM. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.

Serial wire debug functions are supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0+ is configured to support up to four breakpoints and two watch points. The Micro Trace Buffer is implemented on the LPC81xM. The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM SWD debug (RESET = HIGH). The ARM SWD debug port is disabled while the LPC81xM is in reset. The JTAG boundary scan pins are selected by hardware when the part is in boundary scan mode on pins PIO0_0 to PIO0_3 (see Table 4). To perform boundary scan testing, follow these steps: 1. Erase any user code residing in flash. 2. Power up the part with the RESET pin pulled HIGH externally. 3. Wait for at least 250 s. 4. Pull the RESET pin LOW externally. 5. Perform boundary scan operations. 6. Once the boundary scan operations are completed, assert the TRST pin to enable the SWD debug mode, and release the RESET pin (pull HIGH). Remark: The JTAG interface cannot be used for debug purposes.

Thermal characteristics The average chip junction temperature, Tj (C), can be calculated using the following equation: (1) • Tamb = ambient temperature (C), • Rth(j-a) = the package junction-to-ambient thermal resistance (C/W) • PD = sum of internal and I/O power dissipation The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 8.

All rights reserved. Product data sheet Rev. 4.3 — 22 April 2014 49 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller [3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [5] Cb = total capacitance of one bus line in pF. [6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. Fig 30.

[2] IRC enabled, all peripherals off. [3] Watchdog oscillator disabled, Brown-Out Detect (BOD) disabled. [4] Self wakeup-timer disabled. Wake-up from deep power-down causes the LPC800 to go through entire reset process. The wake-up time measured is the time between when a wake-up pin is triggered to wake the device up from the low power modes and from when a GPIO output pin is set in the reset handler. 14.2 XTAL input The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed. In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 35), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 36 and in Table 25 and Table 26. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (the fundamental frequency is represented by L, CL and Table 24.

Product data sheet Rev. 4.3 — 22 April 2014 60 of 76 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 14.3 XTAL Printed Circuit Board (PCB) layout guidelines The crystal should be connected on the PCB as close as possible to the oscillator input and output pins of the chip. Take care that the load capacitors Cx1,Cx2, and Cx3 in case of third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plain. Loops must be made as small as possible in order to keep the noise coupled in via the PCB as small as possible. Also parasitics should stay as small as possible. Values of Cx1 and Cx2 should be chosen smaller accordingly to the increase in parasitics of the PCB layout.

Functional description 8.1 Architectural overview Remark: In the following, the notation LPC17xx refers to all parts: LPC1769/68/67/66/65/64/63. The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and the D-code bus (see Figure 1). The I-code and D-code core buses are faster than the system bus and are used similarly to TCM interfaces: one bus dedicated for instruction fetch (I-code) and one bus for data access (D-code). The use of two core buses allows for simultaneous operations if concurrent operations target different devices. The LPC17xx use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and other bus masters to peripherals in a flexible manner that optimizes performance by allowing peripherals that are on different slaves ports of the matrix to be accessed simultaneously by different bus masters. 8.2 ARM Cortex-M3 processor The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high performance and very low power consumption. The ARM Cortex-M3 offers many new features, including a Thumb-2 instruction set, low interrupt latency, hardware divide, interruptible/continuable multiple load and store instructions, automatic state save and restore for interrupts, tightly integrated interrupt controller with wake-up interrupt controller, and multiple core buses capable of simultaneous accesses. Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. Typically, while one instruction is being executed, its successor is being decoded, and a third instruction is being fetched from memory. The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical Reference Manual that can be found on official ARM website. 8.3 On-chip flash program memory The LPC17xx contain up to 512 kB of on-chip flash memory. A new two-port flash accelerator maximizes performance for use with the two fast AHB-Lite buses. 8.4 On-chip SRAM The LPC17xx contain a total of 64 kB on-chip static RAM memory. This includes the main 32 kB SRAM, accessible by the CPU and DMA controller on a higher-speed bus, and two additional 16 kB each SRAM blocks situated on a separate slave port on the AHB multilayer matrix. This architecture allows CPU and DMA accesses to be spread over three separate RAMs that can be accessed simultaneously. 8.5 Memory Protection Unit (MPU) The LPC17xx have a Memory Protection Unit (MPU) which can be used to improve the reliability of an embedded system by protecting critical data within the user application.

Product data sheet Rev. 9.4 — 4 April 2014 22 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller The MPU allows separating processing tasks by disallowing access to each other's data, disabling access to memory regions, allowing memory regions to be defined as read-only and detecting unexpected memory accesses that could potentially break the system. The MPU separates the memory into distinct regions and implements protection by preventing disallowed accesses. The MPU supports up to 8 regions each of which can be divided into 8 subregions. Accesses to memory locations that are not defined in the MPU regions, or not permitted by the region setting, will cause the Memory Management Fault exception to take place. 8.6 Memory map The LPC17xx incorporates several distinct memory regions, shown in the following figures. Figure 5 shows the overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports address remapping. The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals. The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals. Each peripheral of either type is allocated 16 kB of space. This allows simplifying the address decoding for each peripheral. xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxx x x x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xx xx xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxx x x xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx xxx LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

Product data sheet Rev. 9.4 — 4 April 2014 24 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.7 Nested Vectored Interrupt Controller (NVIC) The NVIC is an integral part of the Cortex-M3. The tight coupling to the CPU allows for low interrupt latency and efficient processing of late arriving interrupts. 8.7.1 Features • Controls system exceptions and peripheral interrupts • In the LPC17xx, the NVIC supports 33 vectored interrupts • 32 programmable interrupt priority levels, with hardware priority level masking • Relocatable vector table • Non-Maskable Interrupt (NMI) • Software interrupt generation 8.7.2 Interrupt sources Each peripheral device has one interrupt line connected to the NVIC but may have several interrupt flags. Individual interrupt flags may also represent more than one interrupt source. Any pin on Port 0 and Port 2 (total of 42 pins) regardless of the selected function, can be programmed to generate an interrupt on a rising edge, a falling edge, or both. 8.8 Pin connect block The pin connect block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Peripherals should be connected to the appropriate pins prior to being activated and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined. Most pins can also be configured as open-drain outputs or to have a pull-up, pull-down, or no resistor enabled. 8.9 General purpose DMA controller The GPDMA is an AMBA AHB compliant peripheral allowing selected peripherals to have DMA support. The GPDMA enables peripheral-to-memory, memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transactions. The source and destination areas can each be either a memory region or a peripheral, and can be accessed through the AHB master. The GPDMA controller allows data transfers between the USB and Ethernet controllers and the various on-chip SRAM areas. The supported APB peripherals are SSP0/1, all UARTs, the I2S-bus interface, the ADC, and the DAC. Two match signals for each timer can be used to trigger DMA transfers. Remark: The Ethernet controller is available on parts LPC1769/68/67/66/64. The USB controller is available on parts LPC1769/68/66/65/64. The I2S-bus interface is available on parts LPC1769/68/67/66/65. The DAC is available on parts LPC1769/68/67/66/65/63.

Each channel can support an unidirectional transfer. • 16 DMA request lines. • Single DMA and burst DMA request signals. Each peripheral connected to the DMA Controller can assert either a burst DMA request or a single DMA request. The DMA burst size is set by programming the DMA Controller. • Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and peripheral-to-peripheral transfers are supported. • Scatter or gather DMA is supported through the use of linked lists. This means that the source and destination areas do not have to occupy contiguous areas of memory. • Hardware DMA channel priority. • AHB slave DMA programming interface. The DMA Controller is programmed by writing to the DMA control registers over the AHB slave interface. • One AHB bus master for transferring data. The interface transfers data when a DMA request goes active. • 32-bit AHB master bus width. • Incrementing or non-incrementing addressing for source and destination. • Programmable DMA burst size. The DMA burst size can be programmed to more efficiently transfer data. • Internal four-word FIFO per channel. • Supports 8, 16, and 32-bit wide transactions. • Big-endian and little-endian support. The DMA Controller defaults to little-endian mode on reset. • An interrupt to the processor can be generated on a DMA completion or when a DMA error has occurred. • Raw interrupt status. The DMA error and DMA count raw interrupt status can be read prior to masking. 8.10 Fast general purpose parallel I/O Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate registers allow setting or clearing any number of outputs simultaneously. The value of the output register may be read back as well as the current state of the port pins. LPC17xx use accelerated GPIO functions: • GPIO registers are accessed through the AHB multilayer bus so that the fastest possible I/O timing can be achieved. • Mask registers allow treating sets of port bits as a group, leaving other bits unchanged. • All GPIO registers are byte and half-word addressable. • Entire port value can be written in one instruction. • Support for Cortex-M3 bit banding. • Support for use with the GPDMA controller.

The edge detection is asynchronous, so it may operate when clocks are not present such as during Power-down mode. Each enabled interrupt can be used to wake up the chip from Power-down mode. 8.10.1 Features • Bit level set and clear registers allow a single instruction to set or clear any number of bits in one port. • Direction control of individual bits. • All I/O default to inputs after reset. • Pull-up/pull-down resistor configuration and open-drain configuration can be programmed through the pin connect block for each GPIO pin. 8.11 Ethernet Remark: The Ethernet controller is available on parts LPC1769/68/67/66/64. The Ethernet block supports bus clock rates of up to 100 MHz (LPC1768/67/66/64) or 120 MHz (LPC1769). See Table 2. The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic frame transmission and reception with scatter-gather DMA off-loads many operations from the CPU. The Ethernet block and the CPU share the ARM Cortex-M3 D-code and system bus through the AHB-multilayer matrix to access the various on-chip SRAM blocks for Ethernet data, control, and status information.

SPI is a full duplex serial interface designed to handle multiple masters and slaves connected to a given bus. Only a single master and a single slave can communicate on the interface during a given data transfer. During a data transfer the master always sends 8 bits to 16 bits of data to the slave, and the slave always sends 8 bits to 16 bits of data to the master. 8.17.1 Features • Maximum SPI data bit rate of 12.5 Mbit/s • Compliant with SPI specification • Synchronous, serial, full duplex communication • Combined SPI master and slave • Maximum data bit rate of one eighth of the input clock rate • 8 bits to 16 bits per transfer 8.18 SSP serial I/O controller The LPC17xx contain two SSP controllers.

Product data sheet Rev. 9.4 — 4 April 2014 32 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.20 I2S-bus serial I/O controllers Remark: The I2S-bus interface is available on parts LPC1769/68/67/66/65/63. See Table 2. The I2S-bus provides a standard communication interface for digital audio applications. The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line, and one word select signal. The basic I2S-bus connection has one master, which is always the master, and one slave. The I2S-bus interface provides a separate transmit and receive channel, each of which can operate as either a master or a slave. 8.20.1 Features • The interface has separate input/output channels each of which can operate in master or slave mode. • Capable of handling 8-bit, 16-bit, and 32-bit word sizes. • Mono and stereo audio data supported. • The sampling frequency can range from 16 kHz to 96 kHz (16, 22.05, 32, 44.1, 48, 96) kHz. • Support for an audio master clock. • Configurable word select period in master mode (separately for I2S-bus input and output). • Two 8-word FIFO data buffers are provided, one for transmit and one for receive. • Generates interrupt requests when buffer levels cross a programmable boundary. • Two DMA requests, controlled by programmable buffer levels. These are connected to the GPDMA block. • Controls include reset, stop and mute options separately for I2S-bus input and I2S-bus output. 8.21 General purpose 32-bit timers/external event counters The LPC17xx include four 32-bit timer/counters. The timer/counter is designed to count cycles of the system derived clock or an externally-supplied clock. It can optionally generate interrupts, generate timed DMA requests, or perform other actions at specified timer values, based on four match registers. Each timer/counter also includes two capture inputs to trap the timer value when an input signal transitions, optionally generating an interrupt. 8.21.1 Features • A 32-bit timer/counter with a programmable 32-bit prescaler. • Counter or timer operation. • Two 32-bit capture channels per timer, that can take a snapshot of the timer value when an input signal transitions. A capture event may also generate an interrupt. • Four 32-bit match registers that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation.

Product data sheet Rev. 9.4 — 4 April 2014 33 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller • Up to four external outputs corresponding to match registers, with the following capabilities: – Set LOW on match. – Set HIGH on match. – Toggle on match. – Do nothing on match. • Up to two match registers can be used to generate timed DMA requests. 8.22 Pulse width modulator The PWM is based on the standard Timer block and inherits all of its features, although only the PWM function is pinned out on the LPC17xx. The Timer is designed to count cycles of the system derived clock and optionally switch pins, generate interrupts or perform other actions when specified timer values occur, based on seven match registers. The PWM function is in addition to these features, and is based on match register events. The ability to separately control rising and falling edge locations allows the PWM to be used for more applications. For instance, multi-phase motor control typically requires three non-overlapping PWM outputs with individual control of all three pulse widths and positions. Two match registers can be used to provide a single edge controlled PWM output. One match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon match. The other match register controls the PWM edge position. Additional single edge controlled PWM outputs require only one match register each, since the repetition rate is the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs. Three match registers can be used to provide a PWM output with both edges controlled. Again, the PWMMR0 match register controls the PWM cycle rate. The other match registers control the two PWM edge positions. Additional double edge controlled PWM outputs require only two match registers each, since the repetition rate is the same for all PWM outputs. With double edge controlled PWM outputs, specific match registers control the rising and falling edge of the output. This allows both positive going PWM pulses (when the rising edge occurs prior to the falling edge), and negative going PWM pulses (when the falling edge occurs prior to the rising edge). 8.22.1 Features • One PWM block with Counter or Timer operation (may use the peripheral clock or one of the capture inputs as the clock source). • Seven match registers allow up to 6 single edge controlled or 3 double edge controlled PWM outputs, or a mix of both types. The match registers also allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation.

Single edge controlled PWM outputs all go high at the beginning of each cycle unless the output is a constant low. Double edge controlled PWM outputs can have either edge occur at any position within a cycle. This allows for both positive going and negative going pulses. • Pulse period and width can be any number of timer counts. This allows complete flexibility in the trade-off between resolution and repetition rate. All PWM outputs will occur at the same repetition rate. • Double edge controlled PWM outputs can be programmed to be either positive going or negative going pulses. • Match register updates are synchronized with pulse outputs to prevent generation of erroneous pulses. Software must ‘release’ new match values before they can become effective. • May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler if the PWM mode is not enabled. 8.23 Motor control PWM The motor control PWM is a specialized PWM supporting 3-phase motors and other combinations. Feedback inputs are provided to automatically sense rotor position and use that information to ramp speed up or down. An abort input is also provided that causes the PWM to immediately release all motor drive outputs. At the same time, the motor control PWM is highly configurable for other generalized timing, counting, capture, and compare applications. 8.24 Quadrature Encoder Interface (QEI) A quadrature encoder, also known as a 2-channel incremental encoder, converts angular displacement into two pulse signals. By monitoring both the number of pulses and the relative phase of the two signals, the user can track the position, direction of rotation, and velocity. In addition, a third channel, or index signal, can be used to reset the position counter. The quadrature encoder interface decodes the digital pulses from a quadrature encoder wheel to integrate position over time and determine direction of rotation. In addition, the QEI can capture the velocity of the encoder wheel. 8.24.1 Features • Tracks encoder position. • Increments/decrements depending on direction. • Programmable for 2 or 4 position counting. • Velocity capture using built-in timer. • Velocity compare function with “less than” interrupt. • Uses 32-bit registers for position and velocity. • Three position compare registers with interrupts. • Index counter for revolution counting. • Index compare register with interrupts. • Can combine index and position interrupts to produce an interrupt for whole and partial revolution displacement.

Any bits of the timer/compare can be masked such that they do not contribute to the match detection. The repetitive interrupt timer can be used to create an interrupt that repeats at predetermined intervals. 8.25.1 Features • 32-bit counter running from PCLK. Counter can be free-running or be reset by a generated interrupt. • 32-bit compare value. • 32-bit compare mask. An interrupt is generated when the counter value equals the compare value, after masking. This allows for combinations not possible with a simple compare. 8.26 ARM Cortex-M3 system tick timer The ARM Cortex-M3 includes a system tick timer (SYSTICK) that is intended to generate a dedicated SYSTICK exception at a 10 ms interval. In the LPC17xx, this timer can be clocked from the internal AHB clock or from a device pin. 8.27 Watchdog timer The purpose of the watchdog is to reset the microcontroller within a reasonable amount of time if it enters an erroneous state. When enabled, the watchdog will generate a system reset if the user program fails to ‘feed’ (or reload) the watchdog within a predetermined amount of time. 8.27.1 Features • Internally resets chip if not periodically reloaded. • Debug mode. • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. • Incorrect/Incomplete feed sequence causes reset/interrupt if enabled. • Flag to indicate watchdog reset. • Programmable 32-bit timer with internal prescaler. • Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 232 4) in multiples of Tcy(WDCLK) 4. • The Watchdog Clock (WDCLK) source can be selected from the Internal RC (IRC) oscillator, the RTC oscillator, or the APB peripheral clock. This gives a wide range of potential timing choices of Watchdog operation under different power reduction LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

It also provides the ability to run the WDT from an entirely internal source that is not dependent on an external crystal and its associated components and wiring for increased reliability. • Includes lock/safe feature. 8.28 RTC and backup registers The RTC is a set of counters for measuring time when system power is on, and optionally when it is off. The RTC on the LPC17xx is designed to have extremely low power consumption, i.e. less than 1 A. The RTC will typically run from the main chip power supply, conserving battery power while the rest of the device is powered up. When operating from a battery, the RTC will continue working down to 2.1 V. Battery power can be provided from a standard 3 V Lithium button cell. An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion of the RTC, moving most of the power consumption out of the time counting function. The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way that will provide less than 1 second per day error when operated at a constant voltage and temperature. A clock output function (see Section 8.29.4) makes measuring the oscillator rate easy and accurate. The RTC contains a small set of backup registers (20 bytes) for holding data while the main part of the LPC17xx is powered off. The RTC includes an alarm function that can wake up the LPC17xx from all reduced power modes with a time resolution of 1 s. 8.28.1 Features • Measures the passage of time to maintain a calendar and clock. • Ultra low power design to support battery powered systems. • Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and Day of Year. • Dedicated power supply pin can be connected to a battery or to the main 3.3 V. • Periodic interrupts can be generated from increments of any field of the time registers. • Backup registers (20 bytes) powered by VBAT. • RTC power supply is isolated from the rest of the chip. 8.29 Clocking and power control 8.29.1 Crystal oscillators The LPC17xx include three independent oscillators. These are the main oscillator, the IRC oscillator, and the RTC oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Any of the three clock sources can be chosen by software to drive the main PLL and ultimately the CPU. Following reset, the LPC17xx will operate from the Internal RC oscillator until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency.

Product data sheet Rev. 9.4 — 4 April 2014 37 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller See Figure 6 for an overview of the LPC17xx clock generation. 8.29.1.1 Internal RC oscillator The IRC may be used as the clock source for the WDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 4 MHz. The IRC is trimmed to 1 % accuracy over the entire voltage and temperature range. Upon power-up or any chip reset, the LPC17xx use the IRC as the clock source. Software may later switch to one of the other available clock sources. 8.29.1.2 Main oscillator The main oscillator can be used as the clock source for the CPU, with or without using the PLL. The main oscillator also provides the clock source for the dedicated USB PLL. The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the main PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock frequency is referred to as CCLK elsewhere in this document. The frequencies of PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The clock frequency for each peripheral can be selected individually and is referred to as PCLK. Refer to Section 8.29.2 for additional information. 8.29.1.3 RTC oscillator The RTC oscillator can be used as the clock source for the RTC block, the main PLL, and/or the CPU. Fig 6.

All rights reserved. Product data sheet Rev. 9.4 — 4 April 2014 38 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.29.2 Main PLL (PLL0) The PLL0 accepts an input clock frequency in the range of 32 kHz to 25 MHz. The input frequency is multiplied up to a high frequency, then divided down to provide the actual clock used by the CPU and/or the USB block. The PLL0 input, in the range of 32 kHz to 25 MHz, may initially be divided down by a value ‘N’, which may be in the range of 1 to 256. This input division provides a wide range of output frequencies from the same input frequency. Following the PLL0 input divider is the PLL0 multiplier. This can multiply the input divider output through the use of a Current Controlled Oscillator (CCO) by a value ‘M’, in the range of 1 through 32768. The resulting frequency must be in the range of 275 MHz to 550 MHz. The multiplier works by dividing the CCO output by the value of M, then using a phase-frequency detector to compare the divided CCO output to the multiplier input. The error value is used to adjust the CCO frequency. The PLL0 is turned off and bypassed following a chip Reset and by entering Power-down mode. PLL0 is enabled by software only. The program must configure and activate the PLL0, wait for the PLL0 to lock, and then connect to the PLL0 as a clock source. 8.29.3 USB PLL (PLL1) The LPC17xx contain a second, dedicated USB PLL1 to provide clocking for the USB interface. The PLL1 receives its clock input from the main oscillator only and provides a fixed 48 MHz clock to the USB block only. The PLL1 is disabled and powered off on reset. If the PLL1 is left disabled, the USB clock will be supplied by the 48 MHz clock from the main PLL0. The PLL1 accepts an input clock frequency in the range of 10 MHz to 25 MHz only. The input frequency is multiplied up the range of 48 MHz for the USB clock using a Current Controlled Oscillators (CCO). It is insured that the PLL1 output has a 50 % duty cycle. 8.29.4 RTC clock output The LPC17xx feature a clock output function intended for synchronizing with external devices and for use during system development to allow checking the internal clocks CCLK, IRC clock, main crystal, RTC clock, and USB clock in the outside world. The RTC clock output allows tuning the RTC frequency without probing the pin, which would distort the results. 8.29.5 Wake-up timer The LPC17xx begin operation at power-up and when awakened from Power-down mode by using the 4 MHz IRC oscillator as the clock source. This allows chip operation to resume quickly. If the main oscillator or the PLL is needed by the application, software will need to enable these features and wait for them to stabilize before they are used as a clock source. When the main oscillator is initially activated, the wake-up timer allows software to ensure that the main oscillator is fully functional before the processor uses it as a clock source and starts to execute instructions. This is important at power on, all types of Reset, and LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

Product data sheet Rev. 9.4 — 4 April 2014 39 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller whenever any of the aforementioned functions are turned off for any reason. Since the oscillator and other functions are turned off during Power-down mode, any wake-up of the processor from Power-down mode makes use of the wake-up timer. The Wake-up Timer monitors the crystal oscillator to check whether it is safe to begin code execution. When power is applied to the chip, or when some event caused the chip to exit Power-down mode, some time is required for the oscillator to produce a signal of sufficient amplitude to drive the clock logic. The amount of time depends on many factors, including the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its electrical characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient conditions. 8.29.6 Power control The LPC17xx support a variety of power control features. There are four special modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, Peripheral Power Control allows shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Each of the peripherals has its own clock divider which provides even better power control. Integrated PMU (Power Management Unit) automatically adjust internal regulators to minimize power consumption during Sleep, Deep sleep, Power-down, and Deep power-down modes. The LPC17xx also implement a separate power domain to allow turning off power to the bulk of the device while maintaining operation of the RTC and a small set of registers for storing data during any of the power-down modes. 8.29.6.1 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core. In Sleep mode, execution of instructions is suspended until either a Reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 8.29.6.2 Deep-sleep mode In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks. The processor state and registers, peripheral registers, and internal SRAM values are preserved throughout Deep-sleep mode and the logic levels of chip pins remain static. The output of the IRC is disabled but the IRC is not powered down for a fast wake-up later. The RTC oscillator is not stopped because the RTC interrupts may be used as the wake-up source. The PLL is automatically turned off and disconnected. The CCLK and USB clock dividers automatically get reset to zero.

Product data sheet Rev. 9.4 — 4 April 2014 40 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller The Deep-sleep mode can be terminated and normal operation resumed by either a Reset or certain specific interrupts that are able to function without clocks. Since all dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power consumption to a very low value. Power to the flash memory is left on in Deep-sleep mode, allowing a very quick wake-up. On wake-up from Deep-sleep mode, the code execution and peripherals activities will resume after 4 cycles expire if the IRC was used before entering Deep-sleep mode. If the main external oscillator was used, the code execution will resume when 4096 cycles expire. PLL and clock dividers need to be reconfigured accordingly. 8.29.6.3 Power-down mode Power-down mode does everything that Deep-sleep mode does, but also turns off the power to the IRC oscillator and the flash memory. This saves more power but requires waiting for resumption of flash operation before execution of code or data access in the flash memory can be accomplished. On the wake-up of Power-down mode, if the IRC was used before entering Power-down mode, it will take IRC 60 s to start-up. After this 4 IRC cycles will expire before the code execution can then be resumed if the code was running from SRAM. In the meantime, the flash wake-up timer then counts 4 MHz IRC clock cycles to make the 100 s flash start-up time. When it times out, access to the flash will be allowed. Users need to reconfigure the PLL and clock dividers accordingly. 8.29.6.4 Deep power-down mode The Deep power-down mode can only be entered from the RTC block. In Deep power-down mode, power is shut off to the entire chip with the exception of the RTC module and the RESET pin. The LPC17xx can wake up from Deep power-down mode via the RESET pin or an alarm match event of the RTC. 8.29.6.5 Wake-up interrupt controller The Wake-up Interrupt Controller (WIC) allows the CPU to automatically wake up from any enabled priority interrupt that can occur while the clocks are stopped in Deep sleep, Power-down, and Deep power-down modes. The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When the CPU enters Deep sleep, Power-down, or Deep power-down mode, the NVIC sends a mask of the current interrupt situation to the WIC.This mask includes all of the interrupts that are both enabled and of sufficient priority to be serviced immediately. With this information, the WIC simply notices when one of the interrupts has occurred and then it wakes up the CPU. The WIC eliminates the need to periodically wake up the CPU and poll the interrupts resulting in additional power savings. 8.29.7 Peripheral power control A Power Control for Peripherals feature allows individual peripherals to be turned off if they are not needed in the application, resulting in additional power savings.

On the LPC17xx, I/O pads are powered by the 3.3 V (VDD(3V3)) pins, while the VDD(REG)(3V3) pin powers the on-chip voltage regulator which in turn provides power to the CPU and most of the peripherals. Depending on the LPC17xx application, a design can use two power options to manage power consumption. The first option assumes that power consumption is not a concern and the design ties the VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power supply for both pads, the CPU, and peripherals. While this solution is simple, it does not support powering down the I/O pad ring “on the fly” while keeping the CPU and peripherals alive. The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator powered independently from the I/O pad ring enables shutting down of the I/O pad power supply “on the fly”, while the CPU and peripherals stay active. The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of power to operate, which can be supplied by an external battery. The device core power (VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. Therefore, there is no power drain from the RTC battery when VDD(REG)(3V3) is available.

The RESET pin is a Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating voltage attains a usable level, causes the RSTOUT pin to go LOW and starts the wake-up timer (see description in Section 8.29.5). The wake-up timer ensures that reset remains asserted until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks have passed, and the flash controller has completed its initialization. Once reset is de-asserted, or, in case of a BOD-triggered reset, once the voltage rises above the BOD threshold, the RSTOUT pin goes HIGH. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the Boot Block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. Fig 7.

Product data sheet Rev. 9.4 — 4 April 2014 43 of 88 NXP Semiconductors LPC1769/68/67/66/65/64/63 32-bit ARM Cortex-M3 microcontroller 8.30.2 Brownout detection The LPC17xx include 2-stage monitoring of the voltage on the VDD(REG)(3V3) pins. If this voltage falls below 2.2 V, the BOD asserts an interrupt signal to the Vectored Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a dedicated status register. The second stage of low-voltage detection asserts reset to inactivate the LPC17xx when the voltage on the VDD(REG)(3V3) pins falls below 1.85 V. This reset prevents alteration of the flash as operation of the various elements of the chip would otherwise become unreliable due to low voltage. The BOD circuit maintains this reset down below 1 V, at which point the power-on reset circuitry maintains the overall reset. Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event loop to sense the condition. 8.30.3 Code security (Code Read Protection - CRP) This feature of the LPC17xx allows user to enable different levels of security in the system so that access to the on-chip flash and use of the JTAG and ISP can be restricted. When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. There are three levels of the Code Read Protection. CRP1 disables access to chip via the JTAG and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased. CRP2 disables access to chip via the JTAG and only allows full flash erase and update using a reduced set of the ISP commands. Running an application with level CRP3 selected fully disables any access to chip via the JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too. It is up to the user’s application to provide (if needed) flash update mechanism using IAP calls or call reinvoke ISP command to enable flash update via UART0. 8.30.4 APB interface The APB peripherals are split into two separate APB buses in order to distribute the bus bandwidth and thereby reducing stalls caused by contention between the CPU and the GPDMA controller. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.

This matrix connects the instruction (I-code) and data (D-code) CPU buses of the ARM Cortex-M3 to the flash memory, the main (32 kB) static RAM, and the Boot ROM. The GPDMA can also access all of these memories. The peripheral DMA controllers, Ethernet, and USB can access all SRAM blocks. Additionally, the matrix connects the CPU system bus and all of the DMA controllers to the various peripheral functions. 8.30.6 External interrupt inputs The LPC17xx include up to 46 edge sensitive interrupt inputs combined with up to four level sensitive external interrupt inputs as selectable pin functions. The external interrupt inputs can optionally be used to wake up the processor from Power-down mode. 8.30.7 Memory mapping control The Cortex-M3 incorporates a mechanism that allows remapping the interrupt vector table to alternate locations in the memory map. This is controlled via the Vector Table Offset Register contained in the NVIC. The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address space. The vector table must be located on a 128 word (512 byte) boundary because the NVIC on the LPC17xx is configured for 128 total interrupts. 8.31 Emulation and debugging Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and trace functions are supported in addition to a standard JTAG debug and parallel trace functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four watch points.

The I/O power dissipation of the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 7.

[2] Parameters are valid over operating temperature range unless otherwise specified. [3] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [4] Cb = total capacitance of one bus line in pF. [5] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [6] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [7] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see the I2C-bus specification UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. Table 14.

Application information 15.1 Suggested USB interface solutions Remark: The USB controller is available as a device/Host/OTG controller on parts LPC1769/68/66/65 and as device-only controller on part LPC1764. If the LPC1769/68/67/66/65/64/63 VDD is always greater than 0 V while VBUS = 5 V, the VBUS pin can be connected directly to the VBUS pin on the USB connector. This applies to bus powered devices where the USB cable supplies the system power. For systems where VDD can be 0 V and VBUS is directly applied to the VBUS pin, precautions must be taken to reduce the voltage to below 3.6 V. The maximum allowable voltage on the VBUS pin is 3.6 V. One method is to use a voltage divider to connect the VBUS pin to the VBUS on the USB connector. The voltage divider ratio should be such that the VBUS pin will be greater than 0.7VDD to indicate a logic HIGH while below the 3.6 V allowable maximum voltage. Use the following operating conditions: VBUSmax = 5.25 V VDD = 3.6 V The voltage divider would need to provide a reduction of 3.6 V/5.25 V or ~0.686 V. Fig 29.

If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed. In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 35), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 36 and in Table 23 and Table 24. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (the fundamental frequency is represented by L, CL and RS). Capacitance CP in Figure 36 represents the parallel package capacitance and should not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal manufacturer. Fig 34.

Also parasitics should stay as small as possible.

General description The PCF8574/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 100 kHz I2C-bus interface, three hardware address inputs and interrupt output operating between 2.5 V and 6 V. The quasi-bidirectional port can be independently assigned as an input to monitor interrupt status or keypads, or as an output to activate indicator devices such as LEDs. System master can read from the input port or write to the output port through a single register. The low current consumption of 2.5 A (typical, static) is great for mobile applications and the latched output ports directly drive LEDs. The PCF8574 and PCF8574A are identical, except for the different fixed portion of the slave address. The three hardware address pins allow eight of each device to be on the same I2C-bus, so there can be up to 16 of these I/O expanders PCF8574/74A together on the same I2C-bus, supporting up to 128 I/Os (for example, 128 LEDs). The active LOW open-drain interrupt output (INT) can be connected to the interrupt logic of the microcontroller and is activated when any input state differs from its corresponding input port register state. It is used to indicate to the microcontroller that an input state has changed and the device needs to be interrogated without the microcontroller continuously polling the input register via the I2C-bus. The internal Power-On Reset (POR) initializes the I/Os as inputs with a weak internal pull-up 100 A current source. 2.
