Cortex™-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4
core features a Floating point unit (FPU) single precision which supports all ARM singleprecision
data-processing instructions and data types. It also implements a full set of DSP
instructions and a memory protection unit (MPU) which enhances application security. The
Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.
The STM32F405xx and STM32F407xx family incorporates high-speed embedded
memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of
backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two
APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose
16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers.
a true random number generator (RNG). They also feature standard and advanced
communication interfaces.

STM32F405xx, STM32F407xx Description
2.1 Full compatibility throughout the family
The STM32F405xx and STM32F407xx are part of the STM32F4 family. They are fully pinto-
pin, software and feature compatible with the STM32F2xx devices, allowing the user to
try different memory densities, peripherals, and performances (FPU, higher frequency) for a
greater degree of freedom during the development cycle.
The STM32F405xx and STM32F407xx devices maintain a close compatibility with the
whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The
STM32F405xx and STM32F407xx, however, are not drop-in replacements for the
STM32F10xxx devices: the two families do not have the same power scheme, and so their
power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F40x
family remains simple as only a few pins are impacted.
Figure 4, Figure 3, Figure 2, and Figure 1 give compatible board designs between the
STM32F40x, STM32F2xxx, and STM32F10xxx families.

STM32F405xx, STM32F407xx Description
2.2.1 ARM® Cortex™-M4F core with embedded Flash and SRAM
The ARM Cortex-M4F processor is the latest generation of ARM processors for embedded
systems. It was developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced response to interrupts.
The ARM Cortex-M4F 32-bit RISC processor features exceptional code-efficiency,
delivering the high-performance expected from an ARM core in the memory size usually
associated with 8- and 16-bit devices.
The processor supports a set of DSP instructions which allow efficient signal processing and
complex algorithm execution.
Its single precision FPU (floating point unit) speeds up software development by using
metalanguage development tools, while avoiding saturation.
The STM32F405xx and STM32F407xx family is compatible with all ARM tools and software.
Figure 5 shows the general block diagram of the STM32F40x family.
Note: Cortex-M4F is binary compatible with Cortex-M3.
2.2.2 Adaptive real-time memory accelerator (ART Accelerator™)
The ART Accelerator™ is a memory accelerator which is optimized for STM32 industrystandard
ARM® Cortex™-M4F processors. It balances the inherent performance advantage
of the ARM Cortex-M4F over Flash memory technologies, which normally requires the
processor to wait for the Flash memory at higher frequencies.
To release the processor full 210 DMIPS performance at this frequency, the accelerator
implements an instruction prefetch queue and branch cache, which increases program
execution speed from the 128-bit Flash memory. Based on CoreMark benchmark, the
performance achieved thanks to the ART accelerator is equivalent to 0 wait state program
execution from Flash memory at a CPU frequency up to 168 MHz.
2.2.3 Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to memory to
prevent one task to accidentally corrupt the memory or resources used by any other active
task. This memory area is organized into up to 8 protected areas that can in turn be divided
up into 8 subareas. The protection area sizes are between 32 bytes and the whole 4
gigabytes of addressable memory.
The MPU is especially helpful for applications where some critical or certified code has to be
protected against the misbehavior of other tasks. It is usually managed by an RTOS (realtime
operating system). If a program accesses a memory location that is prohibited by the
MPU, the RTOS can detect it and take action. In an RTOS environment, the kernel can
dynamically update the MPU area setting, based on the process to be executed.
The MPU is optional and can be bypassed for applications that do not need it.
2.2.4 Embedded Flash memory
The STM32F40x devices embed a Flash memory of 512 Kbytes or 1 Mbytes available for
storing programs and data.
Description STM32F405xx, STM32F407xx
20/185 DocID022152 Rev 4
2.2.5 CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a software
signature during runtime, to be compared with a reference signature generated at link-time
and stored at a given memory location.
2.2.6 Embedded SRAM
All STM32F40x products embed:
• Up to 192 Kbytes of system SRAM including 64 Kbytes of CCM (core coupled memory)
data RAM
RAM memory is accessed (read/write) at CPU clock speed with 0 wait states.
• 4 Kbytes of backup SRAM
This area is accessible only from the CPU. Its content is protected against possible
unwanted write accesses, and is retained in Standby or VBAT mode.
2.2.7 Multi-AHB bus matrix
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, Ethernet, USB
HS) and the slaves (Flash memory, RAM, FSMC, AHB and APB peripherals) and ensures a
seamless and efficient operation even when several high-speed peripherals work
simultaneously.
DocID022152 Rev 4 21/185
STM32F405xx, STM32F407xx Description
Figure 6. Multi-AHB matrix
2.2.8 DMA controller (DMA)
The devices feature two general-purpose dual-port DMAs (DMA1 and DMA2) with 8
streams each. They are able to manage memory-to-memory, peripheral-to-memory and
memory-to-peripheral transfers. They feature dedicated FIFOs for APB/AHB peripherals,
support burst transfer and are designed to provide the maximum peripheral bandwidth
(AHB/APB).
The two DMA controllers support circular buffer management, so that no specific code is
needed when the controller reaches the end of the buffer. The two DMA controllers also
have a double buffering feature, which automates the use and switching of two memory
buffers without requiring any special code.
Each stream is connected to dedicated hardware DMA requests, with support for software
trigger on each stream. Configuration is made by software and transfer sizes between
source and destination are independent.
The DMA can be used with the main peripherals:
• SPI and I2S
• I2C
• USART
• General-purpose, basic and advanced-control timers TIMx
• DAC
• SDIO
• Camera interface (DCMI)
• ADC.

• Maximum FSMC_CLK frequency for synchronous accesses is 60 MHz.
LCD parallel interface
The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build costeffective
graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
2.2.10 Nested vectored interrupt controller (NVIC)
The STM32F405xx and STM32F407xx embed a nested vectored interrupt controller able to
manage 16 priority levels, and handle up to 82 maskable interrupt channels plus the 16
interrupt lines of the Cortex™-M4F.
• Closely coupled NVIC gives low-latency interrupt processing
• Interrupt entry vector table address passed directly to the core
• Allows early processing of interrupts
• Processing of late arriving, higher-priority interrupts
• Support tail chaining
• Processor state automatically saved
• Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
2.2.11 External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 23 edge-detector lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 140 GPIOs can be connected
to the 16 external interrupt lines.
2.2.12 Clocks and startup
On reset the 16 MHz internal RC oscillator is selected as the default CPU clock. The
16 MHz internal RC oscillator is factory-trimmed to offer 1% accuracy over the full
temperature range. The application can then select as system clock either the RC oscillator
or an external 4-26 MHz clock source. This clock can be monitored for failure. If a failure is
detected, the system automatically switches back to the internal RC oscillator and a
software interrupt is generated (if enabled). This clock source is input to a PLL thus allowing
to increase the frequency up to 168 MHz. Similarly, full interrupt management of the PLL
DocID022152 Rev 4 23/185
STM32F405xx, STM32F407xx Description
clock entry is available when necessary (for example if an indirectly used external oscillator
fails).
Several prescalers allow the configuration of the three AHB buses, the high-speed APB
(APB2) and the low-speed APB (APB1) domains. The maximum frequency of the three AHB
buses is 168 MHz while the maximum frequency of the high-speed APB domains is
84 MHz. The maximum allowed frequency of the low-speed APB domain is 42 MHz.
The devices embed a dedicated PLL (PLLI2S) which allows to achieve audio class
performance. In this case, the I2S master clock can generate all standard sampling
frequencies from 8 kHz to 192 kHz.
2.2.13 Boot modes
At startup, boot pins are used to select one out of three boot options:
• Boot from user Flash
• Boot from system memory
• Boot from embedded SRAM
The boot loader is located in system memory. It is used to reprogram the Flash memory by
using USART1 (PA9/PA10), USART3 (PC10/PC11 or PB10/PB11), CAN2 (PB5/PB13), USB
OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade).
2.2.14 Power supply schemes
• VDD = 1.8 to 3.6 V: external power supply for I/Os and the internal regulator (when
enabled), provided externally through VDD pins.
• VSSA, VDDA = 1.8 to 3.6 V: external analog power supplies for ADC, DAC, Reset
blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.
• VBAT = 1.65 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and
backup registers (through power switch) when VDD is not present.
Refer to Figure 21: Power supply scheme for more details.
Note: VDD/VDDA minimum value of 1.7 V is obtained when the device operates in reduced
temperature range, and with the use of an external power supply supervisor (refer to
Section : Internal reset OFF).
Refer to Table 2 in order to identify the packages supporting this option.
2.2.15 Power supply supervisor
Internal reset ON
On packages embedding the PDR_ON pin, the power supply supervisor is enabled by
holding PDR_ON high. On all other packages, the power supply supervisor is always
enabled.
The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry. At power-on, POR/PDR is always active and
ensures proper operation starting from 1.8 V. After the 1.8 V POR threshold level is
reached, the option byte loading process starts, either to confirm or modify default BOR
threshold levels, or to disable BOR permanently. Three BOR thresholds are available
through option bytes. The device remains in reset mode when VDD is below a specified
threshold, VPOR/PDR or VBOR, without the need for an external reset circuit.
Description STM32F405xx, STM32F407xx
24/185 DocID022152 Rev 4
The device also features an embedded programmable voltage detector (PVD) that monitors
the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be
generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is
higher than the VPVD threshold. The interrupt service routine can then generate a warning
message and/or put the MCU into a safe state. The PVD is enabled by software.
Internal reset OFF
This feature is available only on packages featuring the PDR_ON pin. The internal power-on
reset (POR) / power-down reset (PDR) circuitry is disabled with the PDR_ON pin.
An external power supply supervisor should monitor VDD and should maintain the device in
reset mode as long as VDD is below a specified threshold. PDR_ON should be connected to
this external power supply supervisor. Refer to Figure 7: Power supply supervisor
interconnection with internal reset OFF.
Figure 7. Power supply supervisor interconnection with internal reset OFF
1. PDR = 1.7 V for reduce temperature range; PDR = 1.8 V for all temperature range.
The VDD specified threshold, below which the device must be maintained under reset, is
1.8 V (see Figure 7). This supply voltage can drop to 1.7 V when the device operates in the
0 to 70 °C temperature range.
A comprehensive set of power-saving mode allows to design low-power applications.
When the internal reset is OFF, the following integrated features are no more supported:
• The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled
• The brownout reset (BOR) circuitry is disabled
• The embedded programmable voltage detector (PVD) is disabled
• VBAT functionality is no more available and VBAT pin should be connected to VDD
All packages, except for the LQFP64 and LQFP100, allow to disable the internal reset
through the PDR_ON signal.

2.2.16 Voltage regulator
The regulator has four operating modes:
• Regulator ON
– Main regulator mode (MR)
– Low power regulator (LPR)
– Power-down
• Regulator OFF
Regulator ON
On packages embedding the BYPASS_REG pin, the regulator is enabled by holding
BYPASS_REG low. On all other packages, the regulator is always enabled.
There are three power modes configured by software when regulator is ON:
• MR is used in the nominal regulation mode (With different voltage scaling in Run)
In Main regulator mode (MR mode), different voltage scaling are provided to reach the
best compromise between maximum frequency and dynamic power consumption.
Refer to Table 14: General operating conditions.
• LPR is used in the Stop modes
The LP regulator mode is configured by software when entering Stop mode.
• Power-down is used in Standby mode.
The Power-down mode is activated only when entering in Standby mode. The regulator
output is in high impedance and the kernel circuitry is powered down, inducing zero
consumption. The contents of the registers and SRAM are lost)

Two external ceramic capacitors should be connected on VCAP_1 & VCAP_2 pin. Refer to
Figure 21: Power supply scheme and Figure 16: VCAP_1/VCAP_2 operating conditions.
All packages have regulator ON feature.
Regulator OFF
This feature is available only on packages featuring the BYPASS_REG pin. The regulator is
disabled by holding BYPASS_REG high. The regulator OFF mode allows to supply
externally a V12 voltage source through VCAP_1 and VCAP_2 pins.
Since the internal voltage scaling is not manage internally, the external voltage value must
be aligned with the targetted maximum frequency. Refer to Table 14: General operating
conditions.
The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling
capacitors.
Refer to Figure 21: Power supply scheme
When the regulator is OFF, there is no more internal monitoring on V12. An external power
supply supervisor should be used to monitor the V12 of the logic power domain. PA0 pin
should be used for this purpose, and act as power-on reset on V12 power domain.
In regulator OFF mode the following features are no more supported:
• PA0 cannot be used as a GPIO pin since it allows to reset a part of the V12 logic power
domain which is not reset by the NRST pin.
• As long as PA0 is kept low, the debug mode cannot be used under power-on reset. As
a consequence, PA0 and NRST pins must be managed separately if the debug
connection under reset or pre-reset is required.

STM32F405xx, STM32F407xx Description
The following conditions must be respected:
• VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection
between power domains.
• If the time for VCAP_1 and VCAP_2 to reach V12 minimum value is faster than the time for
VDD to reach 1.8 V, then PA0 should be kept low to cover both conditions: until VCAP_1
and VCAP_2 reach V12 minimum value and until VDD reaches 1.8 V (see Figure 10).
• Otherwise, if the time for VCAP_1 and VCAP_2 to reach V12 minimum value is slower
than the time for VDD to reach 1.8 V, then PA0 could be asserted low externally (see
Figure 11).
• If VCAP_1 and VCAP_2 go below V12 minimum value and VDD is higher than 1.8 V, then
a reset must be asserted on PA0 pin.
Note: The minimum value of V12 depends on the maximum frequency targeted in the application
(see Table 14: General operating conditions).

2.2.18 Real-time clock (RTC), backup SRAM and backup registers
The backup domain of the STM32F405xx and STM32F407xx includes:
• The real-time clock (RTC)
• 4 Kbytes of backup SRAM
• 20 backup registers
The real-time clock (RTC) is an independent BCD timer/counter. Dedicated registers contain
the second, minute, hour (in 12/24 hour), week day, date, month, year, in BCD (binarycoded
decimal) format. Correction for 28, 29 (leap year), 30, and 31 day of the month are
performed automatically. The RTC provides a programmable alarm and programmable
periodic interrupts with wakeup from Stop and Standby modes. The sub-seconds value is
also available in binary format.
It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal low-power
RC oscillator or the high-speed external clock divided by 128. The internal low-speed RC

has a typical frequency of 32 kHz. The RTC can be calibrated using an external 512 Hz
output to compensate for any natural quartz deviation.
Two alarm registers are used to generate an alarm at a specific time and calendar fields can
be independently masked for alarm comparison. To generate a periodic interrupt, a 16-bit
programmable binary auto-reload downcounter with programmable resolution is available
and allows automatic wakeup and periodic alarms from every 120 μs to every 36 hours.
A 20-bit prescaler is used for the time base clock. It is by default configured to generate a
time base of 1 second from a clock at 32.768 kHz.
The 4-Kbyte backup SRAM is an EEPROM-like memory area. It can be used to store data
which need to be retained in VBAT and standby mode. This memory area is disabled by
default to minimize power consumption (see Section 2.2.19: Low-power modes). It can be
enabled by software.
The backup registers are 32-bit registers used to store 80 bytes of user application data
when VDD power is not present. Backup registers are not reset by a system, a power reset,
or when the device wakes up from the Standby mode (see Section 2.2.19: Low-power
modes).
Additional 32-bit registers contain the programmable alarm subseconds, seconds, minutes,
hours, day, and date.
Like backup SRAM, the RTC and backup registers are supplied through a switch that is
powered either from the VDD supply when present or from the VBAT pin.
2.2.19 Low-power modes
The STM32F405xx and STM32F407xx support three low-power modes to achieve the best
compromise between low power consumption, short startup time and available wakeup
sources:
• Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
• Stop mode
The Stop mode achieves the lowest power consumption while retaining the contents of
SRAM and registers. All clocks in the V12 domain are stopped, the PLL, the HSI RC
and the HSE crystal oscillators are disabled. The voltage regulator can also be put
either in normal or in low-power mode.
The device can be woken up from the Stop mode by any of the EXTI line (the EXTI line
source can be one of the 16 external lines, the PVD output, the RTC alarm / wakeup /
tamper / time stamp events, the USB OTG FS/HS wakeup or the Ethernet wakeup).
• Standby mode
The Standby mode is used to achieve the lowest power consumption. The internal
voltage regulator is switched off so that the entire V12 domain is powered off. The PLL,
the HSI RC and the HSE crystal oscillators are also switched off. After entering
Description STM32F405xx, STM32F407xx
30/185 DocID022152 Rev 4
Standby mode, the SRAM and register contents are lost except for registers in the
backup domain and the backup SRAM when selected.
The device exits the Standby mode when an external reset (NRST pin), an IWDG reset,
a rising edge on the WKUP pin, or an RTC alarm / wakeup / tamper /time stamp event
occurs.
The standby mode is not supported when the embedded voltage regulator is bypassed
and the V12 domain is controlled by an external power.
2.2.20 VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery, an external
supercapacitor, or from VDD when no external battery and an external supercapacitor are
present.
VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC, the backup registers and the backup SRAM.
Note: When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation.
When PDR_ON pin is not connected to VDD (internal reset OFF), the VBAT functionality is no
more available and VBAT pin should be connected to VDD.
2.2.21 Timers and watchdogs
The STM32F405xx and STM32F407xx devices include two advanced-control timers, eight
general-purpose timers, two basic timers and two watchdog timers.
All timer counters can be frozen in debug mode.
Table 4 compares the features of the advanced-control, general-purpose and basic timers.

Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
• Input capture
• Output compare
• PWM generation (edge- or center-aligned modes)
• One-pulse mode output
If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-
100%).
The advanced-control timer can work together with the TIMx timers via the Timer Link
feature for synchronization or event chaining.
TIM1 and TIM8 support independent DMA request generation.

General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32F40x devices
(see Table 4 for differences).
• TIM2, TIM3, TIM4, TIM5
The STM32F40x include 4 full-featured general-purpose timers: TIM2, TIM5, TIM3,
and TIM4.The TIM2 and TIM5 timers are based on a 32-bit auto-reload
up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are based on a 16-
bit auto-reload up/downcounter and a 16-bit prescaler. They all feature 4 independent
channels for input capture/output compare, PWM or one-pulse mode output. This gives
up to 16 input capture/output compare/PWMs on the largest packages.
The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the
other general-purpose timers and the advanced-control timers TIM1 and TIM8 via the
Timer Link feature for synchronization or event chaining.
Any of these general-purpose timers can be used to generate PWM outputs.
TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are
capable of handling quadrature (incremental) encoder signals and the digital outputs
from 1 to 4 hall-effect sensors.
• TIM9, TIM10, TIM11, TIM12, TIM13, and TIM14
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10, TIM11, TIM13, and TIM14 feature one independent channel, whereas TIM9
and TIM12 have two independent channels for input capture/output compare, PWM or
one-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5
full-featured general-purpose timers. They can also be used as simple time bases.
Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger and waveform generation. They can also be
used as a generic 16-bit time base.
TIM6 and TIM7 support independent DMA request generation.
Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes.
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from
the main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.

STM32F405xx, STM32F407xx Description
SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
downcounter. It features:
• A 24-bit downcounter
• Autoreload capability
• Maskable system interrupt generation when the counter reaches 0
• Programmable clock source.
2.2.22 Inter-integrated circuit interface (I²C)
Up to three I²C bus interfaces can operate in multimaster and slave modes. They can
support the Standard-mode (up to 100 kHz) and Fast-mode (up to 400 kHz) . They support
the 7/10-bit addressing mode and the 7-bit dual addressing mode (as slave). A hardware
CRC generation/verification is embedded.
They can be served by DMA and they support SMBus 2.0/PMBus.
2.2.23 Universal synchronous/asynchronous receiver transmitters (USART)
The STM32F405xx and STM32F407xx embed four universal synchronous/asynchronous
receiver transmitters (USART1, USART2, USART3 and USART6) and two universal
asynchronous receiver transmitters (UART4 and UART5).
These six interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to
communicate at speeds of up to 10.5 Mbit/s. The other available interfaces communicate at
up to 5.25 Mbit/s.
USART1, USART2, USART3 and USART6 also provide hardware management of the CTS
and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication
capability. All interfaces can be served by the DMA controller.
Description STM32F405xx, STM32F407xx
34/185 DocID022152 Rev 4
2.2.24 Serial peripheral interface (SPI)
The STM32F40x feature up to three SPIs in slave and master modes in full-duplex and
simplex communication modes. SPI1 can communicate at up to 42 Mbits/s, SPI2 and SPI3
can communicate at up to 21 Mbit/s. The 3-bit prescaler gives 8 master mode frequencies
and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification
supports basic SD Card/MMC modes. All SPIs can be served by the DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
2.2.25 Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be
operated in master or slave mode, in full duplex and half-duplex communication modes, and
can be configured to operate with a 16-/32-bit resolution as an input or output channel.
Audio sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of
the I2S interfaces is/are configured in master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency.
All I2Sx can be served by the DMA controller.
2.2.26 Audio PLL (PLLI2S)
The devices feature an additional dedicated PLL for audio I2S application. It allows to
achieve error-free I2S sampling clock accuracy without compromising on the CPU
performance, while using USB peripherals.

The PLLI2S configuration can be modified to manage an I2S sample rate change without
disabling the main PLL (PLL) used for CPU, USB and Ethernet interfaces.
The audio PLL can be programmed with very low error to obtain sampling rates ranging
from 8 KHz to 192 KHz.
In addition to the audio PLL, a master clock input pin can be used to synchronize the I2S
flow with an external PLL (or Codec output).
2.2.27 Secure digital input/output interface (SDIO)
An SD/SDIO/MMC host interface is available, that supports MultiMediaCard System
Specification Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit.
The interface allows data transfer at up to 48 MHz, and is compliant with the SD Memory
Card Specification Version 2.0.
The SDIO Card Specification Version 2.0 is also supported with two different databus
modes: 1-bit (default) and 4-bit.
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack
of MMC4.1 or previous.
In addition to SD/SDIO/MMC, this interface is fully compliant with the CE-ATA digital
protocol Rev1.1.
2.2.28 Ethernet MAC interface with dedicated DMA and IEEE 1588 support
Peripheral available only on the STM32F407xx devices.
The STM32F407xx devices provide an IEEE-802.3-2002-compliant media access controller
(MAC) for ethernet LAN communications through an industry-standard mediumindependent
interface (MII) or a reduced medium-independent interface (RMII). The
STM32F407xx requires an external physical interface device (PHY) to connect to the
physical LAN bus (twisted-pair, fiber, etc.). the PHY is connected to the STM32F407xx MII
port using 17 signals for MII or 9 signals for RMII, and can be clocked using the 25 MHz
(MII) from the STM32F407xx.
The STM32F407xx includes the following features:
• Supports 10 and 100 Mbit/s rates
• Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM
and the descriptors (see the STM32F40x reference manual for details)
• Tagged MAC frame support (VLAN support)
• Half-duplex (CSMA/CD) and full-duplex operation
• MAC control sublayer (control frames) support
• 32-bit CRC generation and removal
• Several address filtering modes for physical and multicast address (multicast and
group addresses)
• 32-bit status code for each transmitted or received frame
• Internal FIFOs to buffer transmit and receive frames. The transmit FIFO and the
receive FIFO are both 2 Kbytes.
• Supports hardware PTP (precision time protocol) in accordance with IEEE 1588 2008
(PTP V2) with the time stamp comparator connected to the TIM2 input
• Triggers interrupt when system time becomes greater than target time

36/185 DocID022152 Rev 4
2.2.29 Controller area network (bxCAN)
The two CANs are compliant with the 2.0A and B (active) specifications with a bitrate up to 1
Mbit/s. They can receive and transmit standard frames with 11-bit identifiers as well as
extended frames with 29-bit identifiers. Each CAN has three transmit mailboxes, two receive
FIFOS with 3 stages and 28 shared scalable filter banks (all of them can be used even if one
CAN is used). 256 bytes of SRAM are allocated for each CAN.
2.2.30 Universal serial bus on-the-go full-speed (OTG_FS)
The STM32F405xx and STM32F407xx embed an USB OTG full-speed device/host/OTG
peripheral with integrated transceivers. The USB OTG FS peripheral is compliant with the
USB 2.0 specification and with the OTG 1.0 specification. It has software-configurable
endpoint setting and supports suspend/resume. The USB OTG full-speed controller
requires a dedicated 48 MHz clock that is generated by a PLL connected to the HSE
oscillator. The major features are:
• Combined Rx and Tx FIFO size of 320 × 35 bits with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 4 bidirectional endpoints
• 8 host channels with periodic OUT support
• HNP/SNP/IP inside (no need for any external resistor)
• For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected
2.2.31 Universal serial bus on-the-go high-speed (OTG_HS)
The STM32F405xx and STM32F407xx devices embed a USB OTG high-speed (up to
480 Mb/s) device/host/OTG peripheral. The USB OTG HS supports both full-speed and
high-speed operations. It integrates the transceivers for full-speed operation (12 MB/s) and
features a UTMI low-pin interface (ULPI) for high-speed operation (480 MB/s). When using
the USB OTG HS in HS mode, an external PHY device connected to the ULPI is required.
The USB OTG HS peripheral is compliant with the USB 2.0 specification and with the OTG
1.0 specification. It has software-configurable endpoint setting and supports
suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock
that is generated by a PLL connected to the HSE oscillator.
The major features are:
• Combined Rx and Tx FIFO size of 1 Kbit × 35 with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 6 bidirectional endpoints
• 12 host channels with periodic OUT support
• Internal FS OTG PHY support
• External HS or HS OTG operation supporting ULPI in SDR mode. The OTG PHY is
connected to the microcontroller ULPI port through 12 signals. It can be clocked using
the 60 MHz output.
• Internal USB DMA
• HNP/SNP/IP inside (no need for any external resistor)
• for OTG/Host modes, a power switch is needed in case bus-powered devices are
connected

STM32F405xx, STM32F407xx Description
2.2.32 Digital camera interface (DCMI)
The camera interface is not available in STM32F405xx devices.
STM32F407xx products embed a camera interface that can connect with camera modules
and CMOS sensors through an 8-bit to 14-bit parallel interface, to receive video data. The
camera interface can sustain a data transfer rate up to 54 Mbyte/s at 54 MHz. It features:
• Programmable polarity for the input pixel clock and synchronization signals
• Parallel data communication can be 8-, 10-, 12- or 14-bit
• Supports 8-bit progressive video monochrome or raw bayer format, YCbCr 4:2:2
progressive video, RGB 565 progressive video or compressed data (like JPEG)
• Supports continuous mode or snapshot (a single frame) mode
• Capability to automatically crop the image
2.2.33 Random number generator (RNG)
All STM32F405xx and STM32F407xx products embed an RNG that delivers 32-bit random
numbers generated by an integrated analog circuit.
2.2.34 General-purpose input/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)
or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
alternate functions. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
The I/O configuration can be locked if needed by following a specific sequence in order to
avoid spurious writing to the I/Os registers.
Fast I/O handling allowing maximum I/O toggling up to 84 MHz.
2.2.35 Analog-to-digital converters (ADCs)
Three 12-bit analog-to-digital converters are embedded and each ADC shares up to 16
external channels, performing conversions in the single-shot or scan mode. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:
• Simultaneous sample and hold
• Interleaved sample and hold
The ADC can be served by the DMA controller. An analog watchdog feature allows very
precise monitoring of the converted voltage of one, some or all selected channels. An
interrupt is generated when the converted voltage is outside the programmed thresholds.
To synchronize A/D conversion and timers, the ADCs could be triggered by any of TIM1,
TIM2, TIM3, TIM4, TIM5, or TIM8 timer.
2.2.36 Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 1.8 V and 3.6 V. The temperature sensor is internally
Description STM32F405xx, STM32F407xx
38/185 DocID022152 Rev 4
connected to the ADC1_IN16 input channel which is used to convert the sensor output
voltage into a digital value.
As the offset of the temperature sensor varies from chip to chip due to process variation, the
internal temperature sensor is mainly suitable for applications that detect temperature
changes instead of absolute temperatures. If an accurate temperature reading is needed,
then an external temperature sensor part should be used.
2.2.37 Digital-to-analog converter (DAC)
The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs.
This dual digital Interface supports the following features:
• two DAC converters: one for each output channel
• 8-bit or 12-bit monotonic output
• left or right data alignment in 12-bit mode
• synchronized update capability
• noise-wave generation
• triangular-wave generation
• dual DAC channel independent or simultaneous conversions
• DMA capability for each channel
• external triggers for conversion
• input voltage reference VREF+
Eight DAC trigger inputs are used in the device. The DAC channels are triggered through
the timer update outputs that are also connected to different DMA streams.
2.2.38 Serial wire JTAG debug port (SWJ-DP)
The ARM SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
Debug is performed using 2 pins only instead of 5 required by the JTAG (JTAG pins could
be re-use as GPIO with alternate function): the JTAG TMS and TCK pins are shared with
SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to
switch between JTAG-DP and SW-DP.
2.2.39 Embedded Trace Macrocell™
The ARM Embedded Trace Macrocell provides a greater visibility of the instruction and data
flow inside the CPU core by streaming compressed data at a very high rate from the
STM32F40x through a small number of ETM pins to an external hardware trace port
analyser (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or
any other high-speed channel. Real-time instruction and data flow activity can be recorded
and then formatted for display on the host computer that runs the debugger software. TPA
hardware is commercially available from common development tool vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.

1. Function availability depends on the chosen device.
2. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These I/Os must not be used as a current source (e.g. to drive an LED).
3. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after
reset (because these registers are not reset by the main reset). For details on how to manage these I/Os, refer to the RTC
register description sections in the STM32F4xx reference manual, available from the STMicroelectronics website:
www.st.com.
4. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1).
5. If the device is delivered in an UFBGA176 or WLCSP90 and the BYPASS_REG pin is set to VDD (Regulator off/internal reset
ON mode), then PA0 is used as an internal Reset (active low).

5 Electrical characteristics
5.1 Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
5.1.1 Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).
5.1.2 Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V (for the
1.8 V ≤ VDD ≤ 3.6 V voltage range). They are given only as design guidelines and are not
tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2Σ).
5.1.3 Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
5.1.4 Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 19.
5.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 20.

5.1.6 Power supply scheme
Figure 21. Power supply scheme
1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These
capacitors must be placed as close as possible to, or below, the appropriate pins on the underside of the
PCB to ensure the good functionality of the device.
2. To connect BYPASS_REG and PDR_ON pins, refer to Section 2.2.16: Voltage regulator and Table 2.2.15:
Power supply supervisor.
3. The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling capacitors when the
voltage regulator is OFF.
4. The 4.7 μF ceramic capacitor must be connected to one of the VDD pin.
5. VDDA=VDD and VSSA=VSS.

3. Positive injection is not possible on these I/Os. A negative injection is induced by VINVDD while a negative injection is induced by VIN 25 MHz.
4. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA per ADC for
the analog part.
5. When analog peripheral blocks such as ADCs, DACs, HSE, LSE, HSI, or LSI are ON, an additional power consumption
should be considered.

Figure 29. Typical VBAT current consumption (LSE and RTC ON/backup RAM ON)
I/O system current consumption
The current consumption of the I/O system has two components: static and dynamic.
I/O static current consumption
All the I/Os used as inputs with pull-up generate current consumption when the pin is
externally held low. The value of this current consumption can be simply computed by using
the pull-up/pull-down resistors values given in Table 47: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
Additional I/O current consumption is due to I/Os configured as inputs if an intermediate
voltage level is externally applied. This current consumption is caused by the input Schmitt
trigger circuits used to discriminate the input value. Unless this specific configuration is
required by the application, this supply current consumption can be avoided by configuring
these I/Os in analog mode. This is notably the case of ADC input pins which should be
configured as analog inputs.
Caution: Any floating input pin can also settle to an intermediate voltage level or switch inadvertently,
as a result of external electromagnetic noise. To avoid current consumption related to
floating pins, they must either be configured in analog mode, or forced internally to a definite
digital value. This can be done either by using pull-up/down resistors or by configuring the
pins in output mode.
I/O dynamic current consumption
In addition to the internal peripheral current consumption measured previously (see
Table 27: Peripheral current consumption), the I/Os used by an application also contribute
to the current consumption. When an I/O pin switches, it uses the current from the MCU

On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 27. The MCU is placed
under the following conditions:
• At startup, all I/O pins are configured as analog pins by firmware.
• All peripherals are disabled unless otherwise mentioned
• The code is running from Flash memory and the Flash memory access time is equal to
5 wait states at 168 MHz.
• The code is running from Flash memory and the Flash memory access time is equal to
4 wait states at 144 MHz, and the power scale mode is set to 2.
• ART accelerator and Cache off.
• The given value is calculated by measuring the difference of current consumption
– with all peripherals clocked off
– with one peripheral clocked on (with only the clock applied)
• When the peripherals are enabled: HCLK is the system clock, fPCLK1 = fHCLK/4, and
fPCLK2 = fHCLK/2.
• The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise
specified.

For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 32). CL1 and CL2 are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the
series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF
can be used as a rough estimate of the combined pin and board capacitance) when sizing
CL1 and CL2.
Note: For information on electing the crystal, refer to the application note AN2867 “Oscillator

Equation 2
Equation 2 allows to calculate the increment step (INCSTEP):
fVCO_OUT must be expressed in MHz.
With a modulation depth (md) = ±2 % (4 % peak to peak), and PLLN = 240 (in MHz):
An amplitude quantization error may be generated because the linear modulation profile is
obtained by taking the quantized values (rounded to the nearest integer) of MODPER and
INCSTEP. As a result, the achieved modulation depth is quantized. The percentage
quantized modulation depth is given by the following formula:
As a result:
Figure 35 and Figure 36 show the main PLL output clock waveforms in center spread and
down spread modes, where:
F0 is fPLL_OUT nominal.
Tmode is the modulation period.
md is the modulation depth.

Functional EMS (electromagnetic susceptibility)
While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
• Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
• FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS
through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant
with the IEC 61000-4-4 standard.

STM32F405xx, STM32F407xx Electrical characteristics
A device reset allows normal operations to be resumed.
The test results are given in Table 42. They are based on the EMS levels and classes
defined in application note AN1709.
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
• Corrupted program counter
• Unexpected reset
• Critical Data corruption (control registers...)
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application,
executing EEMBC? code, is running. This emission test is compliant with SAE IEC61967-2
standard which specifies the test board and the pin loading.

5.3.14 Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.
Static latchup
Two complementary static tests are required on six parts to assess the latchup
performance:
• A supply overvoltage is applied to each power supply pin
• A current injection is applied to each input, output and configurable I/O pin
These tests are compliant with EIA/JESD 78A IC latchup standard.

5.3.15 I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (>5
LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out of
5 uA/+0 uA range), or other functional failure (for example reset, oscillator frequency
deviation).
Negative induced leakage current is caused by negative injection and positive induced
leakage current by positive injection.
The test results are given in Table 46.

STM32F405xx, STM32F407xx Electrical characteristics
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 5.2. In particular:
• The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 12).
• The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
IVSS (see Table 12).

I2C interface characteristics
The STM32F405xx and STM32F407xx I2C interface meets the requirements of the
standard I2C communication protocol with the following restrictions: the I/O pins SDA and
SCL are mapped to are not “true” open-drain. When configured as open-drain, the PMOS
connected between the I/O pin and VDD is disabled, but is still present.
The I2C characteristics are described in Table 53. Refer also to Section 5.3.16: I/O port
characteristics for more details on the input/output alternate function characteristics (SDA
and SCL).

I2S interface characteristics
Unless otherwise specified, the parameters given in Table 56 for the i2S interface are
derived from tests performed under the ambient temperature, fPCLKx frequency and VDD
supply voltage conditions summarized in Table 14, with the following configuration:
• Output speed is set to OSPEEDRy[1:0] = 10
• Capacitive load C = 30 pF
• Measurement points are done at CMOS levels: 0.5 VDD
Refer to Section 5.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics (CK, SD, WS).
Note: Refer to the I2S section of RM0090 reference manual for more details on the sampling
frequency (FS). fMCK, fCK, and DCK values reflect only the digital peripheral behavior. The
value of these parameters might be slightly impacted by the source clock accuracy. DCK
depends mainly on the value of ODD bit. The digital contribution leads to a minimum value
of I2SDIV / (2 x I2SDIV + ODD) and a maximum value of (I2SDIV + ODD) / (2 x I2SDIV +
ODD). FS maximum value is supported for each mode/condition.

Note: ADC accuracy vs. negative injection current: injecting a negative current on any analog
input pins should be avoided as this significantly reduces the accuracy of the conversion
being performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in
Section 5.3.16 does not affect the ADC accuracy.

General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 52 or Figure 53,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

1. VREF+ and VREF– inputs are both available on UFBGA176. VREF+ is also available on LQFP100, LQFP144,
and LQFP176. When VREF+ and VREF– are not available, they are internally connected to VDDA and VSSA.

Synchronous waveforms and timings
Figure 59 through Figure 62 represent synchronous waveforms and Table 80 through
Table 82 provide the corresponding timings. The results shown in these tables are obtained
with the following FSMC configuration:
• BurstAccessMode = FSMC_BurstAccessMode_Enable;
• MemoryType = FSMC_MemoryType_CRAM;
• WriteBurst = FSMC_WriteBurst_Enable;
• CLKDivision = 1; (0 is not supported, see the STM32F40xxx/41xxx reference manual)
• DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
In all timing tables, the THCLK is the HCLK clock period (with maximum
FSMC_CLK = 60 MHz).

6.2 Thermal characteristics
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max x ΘJA)
Where:
• TA max is the maximum ambient temperature in °C,
• ΘJA is the package junction-to-ambient thermal resistance, in °C/W,
• PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
• PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = Σ (VOL × IOL) + Σ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.

3 Functional overview
3.1 ARM® CortexTM-M0 core with embedded Flash and SRAM
The ARM Cortex™-M0 processor is the latest generation of ARM processors for embedded
systems. It has been developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced system response to interrupts.
The ARM Cortex™-M0 32-bit RISC processor features exceptional code-efficiency,
delivering the high-performance expected from an ARM core in the memory size usually
associated with 8- and 16-bit devices.
The STM32F0xx family has an embedded ARM core and is therefore compatible with all
ARM tools and software.
Figure 1 shows the general block diagram of the device family.
3.2 Memories
The device has the following features:
Up to 8 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0
wait states and featuring embedded parity checking with exception generation for failcritical
applications.
The non-volatile memory is divided into two arrays:
– 16 to 64 Kbytes of embedded Flash memory for programs and data
– Option bytes
The option bytes are used to write-protect the memory (with 4 KB granularity) and/or
readout-protect the whole memory with the following options:
– Level 0: no readout protection
– Level 1: memory readout protection, the Flash memory cannot be read from or
written to if either debug features are connected or boot in RAM is selected
– Level 2: chip readout protection, debug features (Cortex-M0 serial wire) and boot
in RAM selection disabled
3.3 Boot modes
At startup, the boot pin and boot selector option bit are used to select one of three boot
options:
Boot from User Flash
Boot from System Memory
Boot from embedded SRAM
The boot loader is located in System Memory. It is used to reprogram the Flash memory by
using USART on pins PA14/PA15 or PA9/PA10.

3.4 Cyclic redundancy check calculation unit (CRC)
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a CRC-32 (Ethernet) polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of
the software during runtime, to be compared with a reference signature generated at linktime
and stored at a given memory location.
3.5 Power management
3.5.1 Power supply schemes
VDD = 2.4 to 3.6 V: external power supply for I/Os and the internal regulator. Provided
externally through VDD pins.
VDDA = 2.4 to 3.6 V: external analog power supply for ADC, Reset blocks, RCs and
PLL. The VDDA voltage level must be always greater or equal to the VDD voltage level
and must be provided first.
For more details on how to connect power pins, refer to Figure 10: Power supply scheme.
3.5.2 Power supply supervisors
The device has integrated power-on reset (POR) and power-down reset (PDR) circuits.
They are always active, and ensure proper operation above a threshold of 2 V. The device
remains in reset mode when the monitored supply voltage is below a specified threshold,
VPOR/PDR, without the need for an external reset circuit.
The POR monitors only the VDD supply voltage. During the startup phase it is required
that VDDA should arrive first and be greater than or equal to VDD.
The PDR monitors both the VDD and VDDA supply voltages, however the VDDA power
supply supervisor can be disabled (by programming a dedicated Option bit) to reduce
the power consumption if the application design ensures that VDDA is higher than or
equal to VDD.
3.5.3 Voltage regulator
The regulator has three operating modes: main (MR), low power (LPR) and power down.
MR is used in normal operating mode (Run)
LPR can be used in Stop mode where the power demand is reduced
Power down is used in Standby mode: the regulator output is in high impedance: the
kernel circuitry is powered down, inducing zero consumption (but the contents of the
registers and SRAM are lost)
This regulator is always enabled after reset. It is disabled in Standby mode, providing high
impedance output.

14/88 DocID024849 Rev 1
3.5.4 Low-power modes
The STM32F030x microcontroller supports three low-power modes to achieve the best
compromise between low power consumption, short startup time and available wakeup
sources:
Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
Stop mode
Stop mode achieves very low power consumption while retaining the content of SRAM
and registers. All clocks in the 1.8 V domain are stopped, the PLL, the HSI RC and the
HSE crystal oscillators are disabled. The voltage regulator can also be put either in
normal or in low power mode.
The device can be woken up from Stop mode by any of the EXTI lines. The EXTI line
source can be one of the 16 external lines or the RTC alarm.
Standby mode
The Standby mode is used to achieve the lowest power consumption. The internal
voltage regulator is switched off so that the entire 1.8 V domain is powered off. The
PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering
Standby mode, SRAM and register contents are lost except for the Standby circuitry.
The device exits Standby mode when an external reset (NRST pin), an IWDG reset, a
rising edge on the WKUP pins, or an RTC alarm occurs.
Note: The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop
or Standby mode.
3.6 Clocks and startup
System clock selection is performed on startup, however the internal RC 8 MHz oscillator is
selected as default CPU clock on reset. An external 4-32 MHz clock can be selected, in
which case it is monitored for failure. If failure is detected, the system automatically switches
back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full
interrupt management of the PLL clock entry is available when necessary (for example on
failure of an indirectly used external crystal, resonator or oscillator).
Several prescalers allow the application to configure the frequency of the AHB and the APB
domains. The maximum frequency of the AHB and the APB domains is 48 MHz.

3.7 General-purpose inputs/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions.
The I/O configuration can be locked if needed following a specific sequence in order to
avoid spurious writing to the I/Os registers.
3.8 Direct memory access controller (DMA)
The 5-channel general-purpose DMAs manage memory-to-memory, peripheral-to-memory
and memory-to-peripheral transfers.
The DMA supports circular buffer management, removing the need for user code
intervention when the controller reaches the end of the buffer.
Each channel is connected to dedicated hardware DMA requests, with support for software
trigger on each channel. Configuration is made by software and transfer sizes between
source and destination are independent.
DMA can be used with the main peripherals: SPI, I2C, USART, all TIMx timers (except
TIM14) and ADC.
3.9 Interrupts and events
3.9.1 Nested vectored interrupt controller (NVIC)
The STM32F0xx family embeds a nested vectored interrupt controller able to handle up to
32 maskable interrupt channels (not including the 16 interrupt lines of Cortex™-M0) and 4
priority levels.
Closely coupled NVIC gives low latency interrupt processing
Interrupt entry vector table address passed directly to the core
Closely coupled NVIC core interface
Allows early processing of interrupts
Processing of late arriving higher priority interrupts
Support for tail-chaining
Processor state automatically saved
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimal interrupt
latency.
3.9.2 Extended interrupt/event controller (EXTI)
The extended interrupt/event controller consists of 24 edge detector lines used to generate
interrupt/event requests and wake-up the system. Each line can be independently
configured to select the trigger event (rising edge, falling edge, both) and can be masked
independently. A pending register maintains the status of the interrupt requests. The EXTI
can detect an external line with a pulse width shorter than the internal clock period. Up to 55
GPIOs can be connected to the 16 external interrupt lines.

3.10 Analog to digital converter (ADC)
The 12-bit analog to digital converter has up to 16 external and 2 internal (temperature
sensor/voltage reference measurement) channels and performs conversions in single-shot
or scan modes. In scan mode, automatic conversion is performed on a selected group of
analog inputs.
The ADC can be served by the DMA controller.
An analog watchdog feature allows very precise monitoring of the converted voltage of one,
some or all selected channels. An interrupt is generated when the converted voltage is
outside the programmed thresholds.
3.10.1 Temperature sensor
The temperature sensor (TS) generates a voltage VSENSE that varies linearly with
temperature.
The temperature sensor is internally connected to the ADC_IN16 input channel which is
used to convert the sensor output voltage into a digital value.
The sensor provides good linearity but it has to be calibrated to obtain good overall
accuracy of the temperature measurement. As the offset of the temperature sensor varies
from chip to chip due to process variation, the uncalibrated internal temperature sensor is
suitable for applications that detect temperature changes only.
To improve the accuracy of the temperature sensor measurement, each device is
individually factory-calibrated by ST. The temperature sensor factory calibration data are
stored by ST in the system memory area, accessible in read-only mode.
3.10.2 Internal voltage reference (VREFINT)
The internal voltage reference (VREFINT) provides a stable (bandgap) voltage output for the
ADC. VREFINT is internally connected to the ADC_IN17 input channel. The precise voltage
of VREFINT is individually measured for each part by ST during production test and stored in
the system memory area. It is accessible in read-only mode.

3.11 Timers and watchdogs
Devices of the STM32F0xx family include up to six general-purpose timers, one basic timer
and an advanced control timer.
Table 5 compares the features of the advanced-control, general-purpose and basic timers.
3.11.1 Advanced-control timer (TIM1)
The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on 6
channels. It has complementary PWM outputs with programmable inserted dead times. It
can also be seen as a complete general-purpose timer. The 4 independent channels can be
used for:
Input capture
Output compare
PWM generation (edge or center-aligned modes)
One-pulse mode output
If configured as a standard 16-bit timer, it has the same features as the TIMx timer. If
configured as the 16-bit PWM generator, it has full modulation capability (0-100%).
The counter can be frozen in debug mode.
Many features are shared with those of the standard timers which have the same
architecture. The advanced control timer can therefore work together with the other timers
via the Timer Link feature for synchronization or event chaining.

3.11.2 General-purpose timers (TIM3, TIM14..17)
There are five synchronizable general-purpose timers embedded in the STM32F030x
devices (see Table 5 for differences). Each general-purpose timer can be used to generate
PWM outputs, or as simple time base.
TIM3
STM32F030x devices feature a synchronizable 4-channel general-purpose timer based on
a 16-bit auto-reload up/downcounter and a 16-bit prescaler. TIM3 features 4 independent
channels for input capture/output compare, PWM or one-pulse mode output. This gives up
to 12 input captures/output compares/PWMs on the largest packages.
The TIM3 general-purpose timer can work with the TIM1 advanced-control timer via the
Timer Link feature for synchronization or event chaining.
It provides independent DMA request generation.
The TIM3 timer is capable of handling quadrature (incremental) encoder signals and the
digital outputs from 1 to 3 hall-effect sensors.
Its counter can be frozen in debug mode.
TIM14
This timer is based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM14 features one single channel for input capture/output compare, PWM or one-pulse
mode output.
Its counter can be frozen in debug mode.
TIM15, TIM16 and TIM17
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM15 has two independent channels, whereas TIM16 and TIM17 feature one single
channel for input capture/output compare, PWM or one-pulse mode output.
The TIM15, TIM16 and TIM17 timers can work together, and TIM15 can also operate with
TIM1 via the Timer Link feature for synchronization or event chaining.
TIM15 can be synchronized with TIM16 and TIM17.
TIM15, TIM16, and TIM17 have a complementary output with dead-time generation and
independent DMA request generation.
Their counters can be frozen in debug mode.
3.11.3 Basic timer TIM6
This timer is mainly used as a generic 16-bit time base.
3.11.4 Independent watchdog (IWDG)
The independent watchdog is based on an 8-bit prescaler and 12-bit downcounter with
user-defined refresh window. It is clocked from an independent 40 kHz internal RC and as it
operates independently from the main clock, it can operate in Stop and Standby modes. It
can be used either as a watchdog to reset the device when a problem occurs, or as a free
Functional overview STM32F030x4 STM32F030x6 STM32F030x8
20/88 DocID024849 Rev 1
running timer for application timeout management. It is hardware or software configurable
through the option bytes. The counter can be frozen in debug mode.
3.11.5 System window watchdog (WWDG)
The system window watchdog is based on a 7-bit downcounter that can be set as free
running. It can be used as a watchdog to reset the device when a problem occurs. It is
clocked from the APB clock (PCLK). It has an early warning interrupt capability and the
counter can be frozen in debug mode.
3.11.6 SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
down counter. It features:
A 24-bit down counter
Autoreload capability
Maskable system interrupt generation when the counter reaches 0
Programmable clock source (HCLK or HCLK/8)
3.12 Real-time clock (RTC)
The RTC is an independent BCD timer/counter. Its main features are the following:
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format
Automatically correction for 28, 29 (leap year), 30, and 31 day of the month
Programmable alarm with wake up from Stop and Standby mode capability
On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to
synchronize it with a master clock.
Digital calibration circuit with 1 ppm resolution, to compensate for quartz crystal
inaccuracy
2 anti-tamper detection pins with programmable filter. The MCU can be woken up from
Stop and Standby modes on tamper event detection.
Timestamp feature which can be used to save the calendar content. This function can
triggered by an event on the timestamp pin, or by a tamper event. The MCU can be
woken up from Stop and Standby modes on timestamp event detection.
Periodic wakeup from Stop/Standby
Reference clock detection: a more precise second source clock (50 or 60 Hz) can be
used to enhance the calendar precision.
The RTC clock sources can be:
A 32.768 kHz external crystal
A resonator or oscillator
The internal low-power RC oscillator (typical frequency of 40 kHz)
The high-speed external clock divided by 32

3.13 Inter-integrated circuit interfaces (I2C)
Up to two I2C interfaces (I2C1 and I2C2) can operate in multimaster or slave modes. Both
can support Standard mode (up to 100 kbit/s) or Fast mode (up to 400 kbit/s). I2C1 also
supports Fast Mode Plus (up to 1 Mbit/s) with 20 mA output drive.
Both support 7-bit and 10-bit addressing modes, multiple 7-bit slave addresses (2
addresses, 1 with configurable mask). They also include programmable analog and digital
noise filters.
In addition, I2C1 provides hardware support for SMBUS 2.0 and PMBUS 1.1: ARP
capability, Host notify protocol, hardware CRC (PEC) generation/verification, timeouts
verifications and ALERT protocol management.
The I2C interfaces can be served by the DMA controller.
Refer to Table 7 for the differences between I2C1 and I2C2.

3.14 Universal synchronous/asynchronous receiver transmitters
(USART)
The device embeds up to two universal synchronous/asynchronous receiver transmitters
(USART1 and USART2), which communicate at speeds of up to 6 Mbit/s.
They provide hardware management of the CTS and RTS signals, multiprocessor
communication mode, master synchronous communication and single-wire half-duplex
communication mode. The USART1 supports also auto baud rate feature.
The USART interfaces can be served by the DMA controller.
Refer to Table 8 for the differences between USART1 and USART2.
3.15 Serial peripheral interface (SPI)
Up to two SPIs are able to communicate up to 18 Mbits/s in slave and master modes in fullduplex
and half-duplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame size is configurable from 4 bits to 16 bits.
Refer to Table 9 for the differences between SPI1 and SPI2.

1. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount
of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These GPIOs must not be used as current sources (e.g. to drive an LED).
2. This feature is available on STM32F030x6 and STM32F030x4 devices only.
3. This feature is available on STM32F030x8 devices only.
4. On LQFP32 package, PB2 and PB8 should be treated as unconnected pins (even when they are not
available on the package, they are not forced to a defined level by hardware).
5. After reset, these pins are configured as SWDIO and SWCLK alternate functions, and the internal pull-up on
SWDIO pin and internal pull-down on SWCLK pin are activated.

6 Electrical characteristics
6.1 Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
6.1.1 Minimum and maximum values
Unless otherwise specified, the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3).
6.1.2 Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = VDDA = 3.3 V. They
are given only as design guidelines and are not tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2).
6.1.3 Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
6.1.4 Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 8.
6.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 9.

Caution: Each power supply pair (VDD/VSS, VDDA/VSSA etc.) must be decoupled with filtering ceramic
capacitors as shown above. These capacitors must be placed as close as possible to, or
below, the appropriate pins on the underside of the PCB to ensure the good functionality of
the device.

For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 24). CL1 and CL2 are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the
series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF
can be used as a rough estimate of the combined pin and board capacitance) when sizing
CL1 and CL2. Refer to the application note AN2867 “Oscillator design guide for ST
microcontrollers” available from the ST website www.st.com.

Note: For CL1 and CL2 it is recommended to use high-quality ceramic capacitors in the 5 pF to
15 pF range selected to match the requirements of the crystal or resonator. CL1 and CL2, are
usually the same size. The crystal manufacturer typically specifies a load capacitance which
is the series combination of CL1 and CL2.
Load capacitance CL has the following formula: CL = CL1 x CL2 / (CL1 + CL2) + Cstray where
Cstray is the pin capacitance and board or trace PCB-related capacitance. Typically, it is
between 2 pF and 7 pF.
Caution: To avoid exceeding the maximum value of CL1 and CL2 (15 pF) it is strongly recommended
to use a resonator with a load capacitance CL 7 pF. Never use a resonator with a load
capacitance of 12.5 pF.
Example: if you choose a resonator with a load capacitance of CL = 6 pF, and Cstray = 2 pF,
then CL1 = CL2 = 8 pF.

Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.

Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
Corrupted program counter
Unexpected reset
Critical Data corruption (control registers...)
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application is
executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with
IEC 61967-2 standard which specifies the test board and the pin loading.

5.3.11 Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.
Static latch-up
Two complementary static tests are required on six parts to assess the latch-up
performance:
A supply overvoltage is applied to each power supply pin
A current injection is applied to each input, output and configurable I/O pin
These tests are compliant with EIA/JESD 78A IC latch-up standard.

5.3.12 I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (>5
LSB TUE), out of spec current injection on adjacent pins or other functional failure (for
example reset, oscillator frequency deviation).

Output driving current
The GPIOs (general-purpose inputs/outputs) can sink or source up to ±8 mA, and sink or
source up to ±20 mA (with a relaxed VOL/VOH) except PC13, PC14 and PC15 which can
sink or source up to +/-3mA. When using the GPIOs PC13 to PC15 in output mode, the
speed should not exceed 2 MHz with a maximum load of 30 pF.
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 5.2:
The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 7).
The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
IVSS (see Table 7).

Unless otherwise specified, the parameters given in Table 36 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in

Figure 38. Typical connection diagram using the ADC
1. Refer to Table 46 for the values of RAIN, RADC and CADC.
2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (roughly 7 pF). A high Cparasitic value will downgrade conversion accuracy. To remedy
this, fADC should be reduced.
General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 39 or Figure 40,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

6.2 Thermal characteristics
The maximum chip junction temperature (TJmax) must never exceed the values given in
Table 9: General operating conditions on page 38.
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max × JA)
Where:
TA max is the maximum ambient temperature in C,
JA is the package junction-to-ambient thermal resistance, in C/W,
PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = (VOL × IOL) + ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the

6.2.2 Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in Table 60: Ordering information scheme.
Each temperature range suffix corresponds to a specific guaranteed ambient temperature at
maximum dissipation and, to a specific maximum junction temperature.
As applications do not commonly use the STM32F103xx at maximum dissipation, it is useful
to calculate the exact power consumption and junction temperature to determine which
temperature range will be best suited to the application.
The following examples show how to calculate the temperature range needed for a given
application.
Example 1: High-performance application
Assuming the following application conditions:
Maximum ambient temperature TAmax = 82 °C (measured according to JESD51-2),
IDDmax = 50 mA, VDD = 3.5 V, maximum 20 I/Os used at the same time in output at low
level with IOL = 8 mA, VOL= 0.4 V and maximum 8 I/Os used at the same time in output
at low level with IOL = 20 mA, VOL= 1.3 V
PINTmax = 50 mA × 3.5 V= 175 mW
PIOmax = 20 × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW
This gives: PINTmax = 175 mW and PIOmax = 272 mW:
PDmax = 175 + 272 = 447 mW
Thus: PDmax = 447 mW
Using the values obtained in Table 59 TJmax is calculated as follows:
– For LQFP100, 46 °C/W
TJmax = 82 °C + (46 °C/W × 447 mW) = 82 °C + 20.6 °C = 102.6 °C
This is within the range of the suffix 6 version parts (–40 < TJ < 105 °C).
In this case, parts must be ordered at least with the temperature range suffix 6 (see
Table 60: Ordering information scheme).
Example 2: High-temperature application
Using the same rules, it is possible to address applications that run at high ambient
temperatures with a low dissipation, as long as junction temperature TJ remains within the
specified range.
Assuming the following application conditions:
Maximum ambient temperature TAmax = 115 °C (measured according to JESD51-2),
IDDmax = 20 mA, VDD = 3.5 V, maximum 20 I/Os used at the same time in output at low
level with IOL = 8 mA, VOL= 0.4 V
PINTmax = 20 mA × 3.5 V= 70 mW
PIOmax = 20 × 8 mA × 0.4 V = 64 mW
This gives: PINTmax = 70 mW and PIOmax = 64 mW:
PDmax = 70 + 64 = 134 mW
Thus: PDmax = 134 mW
DocID13587 Rev 16 95/105
STM32F103x8, STM32F103xB Package characteristics
104
Using the values obtained in Table 59 TJmax is calculated as follows:
– For LQFP100, 46 °C/W
TJmax = 115 °C + (46 °C/W × 134 mW) = 115 °C + 6.2 °C = 121.2 °C
This is within the range of the suffix 7 version parts (–40 < TJ < 125 °C).
In this case, parts must be ordered at least with the temperature range suffix 7 (see
Table 60: Ordering information scheme).

2 Absolute maximum ratings
Note: Absolute maximum ratings are those values beyond which damage to the device may occur.
Functional operation under these condition is not implied.
Externally applied V+ and V- can have a maximum magnitude of +7 V, but their absolute
addition can not exceed 13 V.
Running on internal charge pump, intrinsic self limitation allows exceeding those values
without any damage.
Startup voltage sequence (VCC, then V+, then V-) is critical, therefore it is not recommended
to use this device using externally applied voltage to V+ and V-.

VOUT = Desired output voltage, |VOUT| = 1.25 (1 + R2/R1)
IOUT = Desired output current
fMIN = Minimum desired output switching frequency at the selected values of VIN and IO
VRIPPLE = Desired peak to peak output ripple voltage. In practice, the calculated capacitor
value will and to be increased due to its equivalent series resistance and board layout. The
ripple voltage should be kept to a low value since it will directly affect the line and load
regulation.

Description
The ST1S10 is a high efficiency step-down PWM
current mode switching regulator capable of
providing up to 3 A of output current. The device
operates with an input supply range from 2.5 V to
18 V and provides an adjustable output voltage
from 0.8 V (VFB) to 0.85*VIN_SW [VOUT =
VFB*(1+R1/R2)]. It operates either at a 900 kHz
fixed frequency or can be synchronized to an
external clock (from 400 kHz to 1.2 MHz). The
high switching frequency allows the use of tiny
SMD external components, while the integrated
synchronous rectifier eliminates the need for a
Schottky diode. The ST1S10 provides excellent
transient response, and is fully protected against
thermal overheating, switching over-current and
output short circuit.
The ST1S10 is the ideal choice for point-of-load
regulators or LDO pre-regulation.

5 Application information
5.1 Description
The ST1S10 is a high efficiency synchronous step-down DC-DC converter with inhibit
function. It provides up to 3 A over an input voltage range of 2.5 V to 18 V, and the output
voltage can be adjusted from 0.8 V up to 85% of the input voltage level. The synchronous
rectification removes the need for an external Schottky diode and allows higher efficiency
even at very low output voltages.
A high internal switching frequency (0.9 MHz) allows the use of tiny surface-mount
components, as well as a resistor divider to set the output voltage value. In typical
application conditions, only an inductor and 3 capacitors are required for proper operation.
The device can operate in PWM mode with a fixed frequency or synchronized to an external
frequency through the SYNC pin. The current mode PWM architecture and stable operation
with low ESR SMD ceramic capacitors results in low, predictable output ripple. No external
compensation is needed.
To maximize power conversion efficiency, the ST1S10 works in pulse skipping mode at light
load conditions and automatically switches to PWM mode when the output current
increases.
The ST1S10 is equipped with thermal shut down protection activated at 150 °C (typ.).
Cycle-by-cycle short circuit protection provides protection against shorted outputs for the
application and the regulator. An internal soft start for start-up current limiting and power ON
delay of 275 μs (typ.) helps to reduce inrush current during start-up.
5.2 External components selection
5.2.1 Input capacitor
The ST1S10 features two VIN pins: VIN_SW for the power supply input voltage where the
switching peak current is drawn, and VIN_A to supply the ST1S10 internal circuitry and
drivers.
The VIN_SW input capacitor reduces the current peaks drawn from the input power supply
and reduces switching noise in the IC. A high power supply source impedance requires
larger input capacitance.
For the VIN_SW input capacitor the RMS current rating is a critical parameter that must be
higher than the RMS input current. The maximum RMS input current can be calculated
using the following equation:
Equation 1
where η is the expected system efficiency, D is the duty cycle and IO is the output DC
current. The duty cycle can be derived using the equation:
η
D
η
2 D
I I D -
2 2
RMS O = ⋅ ⋅ +
ST1S10 Application information
Doc ID 13844 Rev 5 11/29
Equation 2
D = (VOUT + VF) / (VIN-VSW)
where VF is the voltage drop across the internal NMOS, and VSW represents the voltage
drop across the internal PDMOS. The minimum duty cycle (at VIN_max) and the maximum
duty cycle (at VIN_min) should be considered in order to determine the max IRMS flowing
through the input capacitor.
A minimum value of 4.7 μF for the VIN_SW and a 0.1 μF ceramic capacitor for the VIN_A are
suitable in most application conditions. A 10 μF or higher ceramic capacitor for the VIN_SW
and a 1 μF or higher for the VIN_A are recommended in cases of higher power supply source
impedance or where long wires are needed between the power supply source and the VIN
pins. The above higher input capacitor values are also recommended in cases where an
output capacitive load is present (47 μF < CLOAD < 100 μF), which could impact the
switching peak current drawn from the input capacitor during the start-up transient.
In cases of very high output capacitive loads (CLOAD > 100 μF), all input/output capacitor
values shall be modified as described in the OCP and SCP operation section 5.8.5 of this
document.
The input ceramic capacitors should have a voltage rating in the range of 1.5 times the
maximum input voltage and be located as close as possible to VIN pins.
5.3 Output capacitor (VOUT > 2.5 V)
The most important parameters for the output capacitor are the capacitance, the ESR and
the voltage rating. The capacitance and the ESR affect the control loop stability, the output
ripple voltage and transient response of the regulator.
The ripple due to the capacitance can be calculated with the following equation:
Equation 3
VRIPPLE(C) = (0.125 x ΔISW) / (FS x COUT)
where FS is the PWM switching frequency and ΔISW is the inductor peak-to-peak switching
current, which can be calculated as:
Equation 4
ΔISW = [(VIN - VOUT) / (FS x L)] x D
where D is the duty cycle.
The ripple due to the ESR is given by:
Equation 5
VRIPPLE(ESR) = ΔISW x ESR
The equations above can be used to define the capacitor selection range, but final values
should be verified by testing an evaluation circuit.
Lower ESR ceramic capacitors are usually recommended to reduce the output ripple
voltage. Capacitors with higher voltage ratings have lower ESR values, resulting in lower
output ripple voltage.
Application information ST1S10
12/29 Doc ID 13844 Rev 5
Also, the capacitor ESL value impacts the output ripple voltage, but ceramic capacitors
usually have very low ESL, making ripple voltages due to the ESL negligible. In order to
reduce ripple voltages due to the parasitic inductive effect, the output capacitor connection
paths should be kept as short as possible.
The ST1S10 has been designed to perform best with ceramic capacitors. Under typical
application conditions a minimum ceramic capacitor value of 22 μF is recommended on the
output, but higher values are suitable considering that the control loop has been designed to
work properly with a natural output LC frequency provided by a 3.3 μH inductor and 22 μF
output capacitor. If the high capacitive load application circuit shown in Figure 3 is used, a
47 μF (or 2 x 22 μF capacitors in parallel) could be needed as described in the OCP and
SCP operation Section 5.8.5: SCP and OCP operation with high capacitive load. of this
document.
The use of ceramic capacitors with voltage ratings in the range of 1.5 times the maximum
output voltage is recommended.
5.4 Output capacitor (0.8 V < VOUT < 2.5 V)
For applications with lower output voltage levels (Vout < 2.5 V) the output capacitance and
inductor values should be selected in a way that improves the DC-DC control loop behavior.
In this output condition two cases must be considered: VIN > 8 V and VIN < 8 V.
For VIN < 8 V the use of 2 x 22 μF capacitors in parallel to the output is recommended, as
shown in Figure 4.
For VIN > 8 V, a 100 μF electrolytic capacitor with ESR < 0.1 Ω should be added in parallel to
the 2 x 22 μF output capacitors as shown in Figure 5.
5.5 Output voltage selection
The output voltage can be adjusted from 0.8 V up to 85% of the input voltage level by
connecting a resistor divider (see R1 and R2 in the typical application circuit) between the
output and the VFB pin. A resistor divider with R2 in the range of 20 kΩ is a suitable
compromise in terms of current consumption. Once the R2 value is selected, R1 can be
calculated using the following equation:
Equation 6
R1 = R2 x (VOUT - VFB) / VFB
where VFB = 0.8 V (typ.).
Lower values are suitable as well, but will increase current consumption. Be aware that duty
cycle must be kept below 85% at all application conditions, so that:
Equation 7
D = (VOUT + VF) / (VIN-VSW) < 0.85
where VF is the voltage drop across the internal NMOS, and VSW represents the voltage
drop across the internal PDMOS.
Note that once the output current is fixed, higher VOUT levels increase the power dissipation
of the device leading to an increase in the operating junction temperature. It is
ST1S10 Application information
Doc ID 13844 Rev 5 13/29
recommended to select a VOUT level which maintains the junction temperature below the
thermal shut-down protection threshold (150°C typ.) at the rated output current. The
following equation can be used to calculate the junction temperature (TJ):
Equation 8
TJ = {[VOUT x IOUT x RthJA x (1-η)] / η} +TAMB
where RthJA is the junction-to-ambient thermal resistance, η is the efficiency at the rated IOUT
current and TAMB is the ambient temperature.
To ensure safe operating conditions the application should be designed to keep TJ < 140°C.
5.6 Inductor (VOUT > 2.5 V)
The inductor value fixes the ripple current flowing through output capacitor and switching
peak current. The ripple current should be kept in the range of 20-40% of IOUT_MAX (for
example it is 0.6 - 1.2 A at IOUT = 3 A). The approximate inductor value can be obtained with
the following equation:
Equation 9
L = [(VIN - VOUT) / ΔISW] x TON
where TON is the ON time of the internal switch, given by:
TON = D/FS
The inductor should be selected with saturation current (ISAT) equal to or higher than the
inductor peak current, which can be calculated with the following equation:
Equation 10
IPK = IO + (ΔISW/2), ISAT ≥ IPK
The inductor peak current must be designed so that it does not exceed the switching current
limit.
5.7 Inductor (0.8 V < VOUT < 2.5 V)
For applications with lower output voltage levels (Vout < 2.5 V) the description in the previous
section is still valid but it is recommended to keep the inductor values in a range from 1μH to
2.2 μH in order to improve the DC-DC control loop behavior, and increase the output
capacitance depending on the VIN level as shown in the Figure 4 and Figure 5. In most
application conditions a 2.2 μH inductor is the best compromise between DC-DC control
loop behavior and output voltage ripple.
5.8 Function operation
5.8.1 Sync operation
The ST1S10 operates at a fixed frequency or can be synchronized to an external frequency
with the SYNC pin. The ST1S10 switches at a frequency of 900 kHz when the SYNC pin is
connected to ground, and can synchronize the switching frequency between 400 kHz to 1.2
Application information ST1S10
14/29 Doc ID 13844 Rev 5
MHz from an external clock applied to the SYNC pin. When the SYNC feature is not used,
this pin must be connected to ground with a path as short as possible to avoid any possible
noise injected in the SYNC internal circuitry.
5.8.2 Inhibit function
The inhibit pin can be used to turn OFF the regulator when pulled down, thus drastically
reducing the current consumption down to less than 6 μA. When the inhibit feature is not
used, this pin must be tied to VIN to keep the regulator output ON at all times. To ensure
proper operation, the signal source used to drive the inhibit pin must be able to swing above
and below the specified thresholds listed in the electrical characteristics section under VINH.
Any slew rate can be used to drive the inhibit pin.
5.8.3 OCP (overcurrent protection)
The ST1S10 DC-DC converter is equipped with a switch overcurrent protection. In order to
provide protection for the application and the internal power switches and bonding wires, the
device goes into a shutdown state if the switch current limit is reached and is kept in this
condition for the TOFF period (TOFF(OCP) = 135 μs typ.) and turns on again for the TON period
(TON(OCP) = 22 μs typ.) under typical application conditions. This operation is repeated cycle
by cycle. Normal operation is resumed when no over-current is detected.
5.8.4 SCP (short circuit protection)
In order to protect the entire application and reduce the total power dissipation during an
overload or an output short circuit condition, the device is equipped with dynamic short
circuit protection which works by internally monitoring the VFB (feedback voltage).
In the event of an overload or output short circuit, if the VOUT voltage is reduced causing the
feedback voltage (VFB) to drop below 0.3 V (typ.), the device goes into shutdown for the
TOFF time (TOFF(SCP) = 288 μs typ.) and turns on again for the TON period (TON(SCP) = 130
μs typ.). This operation is repeated cycle by cycle, and normal operation is resumed when
no overload is detected (VFB > 0.3 V typ.) for the full TON period.
This dynamic operation can greatly reduce the power dissipation in overload conditions,
while still ensuring excellent power-on startup in most conditions.
5.8.5 SCP and OCP operation with high capacitive load
Thanks to the OCP and SCP circuit, ST1S10 is strongly protected against damage from
short circuit and overload.
However, a highly capacitive load on the output may cause difficulties during start-up. This
can be resolved by using the modified application circuit shown in Figure 3, in which a
minimum of 10 μF for C1 and a 4.7 μF ceramic capacitor for C3 are used. Moreover, for
CLOAD > 100 μF, it is necessary to add the C4 capacitor in parallel to the upper voltage
divider resistor (R1) as shown in Figure 3. The recommended value for C4 is 4.7 nF.
Note that C4 may impact the control loop response and should be added only when a
capacitive load higher than 100 μF is continuously present. If the high capacitive load is
variable or not present at all times, in addition to C4 an increase in the output ceramic
capacitor C2 from 22 μF to 47 μF (or 2 x 22 μF capacitors in parallel) is recommended. Also
in this case it is suggested to further increase the input capacitors to a minimum of 10 μF for
C1 and a 4.7 μF ceramic capacitor for C3 as shown in Figure 3.

0.8V 0 due to a load drop, the voltage at pin INV will
be kept at 2.5V by the local feedback of the error amplifier, a network connected between pins INV and
COMP that introduces a long time constant to achieve high PF (this is why ΔVo can be large). As a result,
the current through R2 will remain equal to 2.5/R2 but that through R1 will become:
.
The difference current ΔIR1=I'R1-IR2=I'R1-IR1=ΔVo/R1 will flow through the compensation network and enter
the error amplifier output (pin COMP). This current is monitored inside the L6562 and if it reaches about
37 μA the output voltage of the multiplier is forced to decrease, thus smoothly reducing the energy delivered
to the output. As the current exceeds 40 μA, the OVP is triggered (Dynamic OVP): the gate-drive is
forced low to switch off the external power transistor and the IC put in an idle state. This condition is maintained
until the current falls below approximately 10 μA, which re-enables the internal starter and allows
switching to restart. The output ΔVo that is able to trigger the Dynamic OVP function is then:
.
An important advantage of this technique is that the OV level can be set independently of the regulated
output voltage: the latter depends on the ratio of R1 to R2, the former on the individual value of R1. Another
advantage is the precision: the tolerance of the detection current is 12%, that is 12% tolerance on ΔVo.
Since ΔVo << Vo, the tolerance on the absolute value will be proportionally reduced.
Example: Vo = 400 V, ΔVo = 40 V. Then: R1=40V/40μA=1MΩ; R2=1MΩ·2.5/(400-2.5)=6.289kΩ. The tolerance
on the OVP level due to the L6562 will be 40·0.12=4.8V, that is 1.2% of the regulated value.

L6562
When the load of a PFC pre-regulator is very low, the output voltage tends to stay steadily above the nominal
value, which cannot be handled by the Dynamic OVP. If this occurs, however, the error amplifier output
will saturate low; hence, when this is detected, the external power transistor is switched off and the IC
put in an idle state (Static OVP). Normal operation is resumed as the error amplifier goes back into its linear
region. As a result, the L6562 will work in burst-mode, with a repetition rate that can be very low.
When either OVP is activated the quiescent consumption of the IC is reduced to minimize the discharge
of the Vcc capacitor and increase the hold-up capability of the IC supply system.
4.2 THD optimizer circuit
The L6562 is equipped with a special circuit that reduces the conduction dead-angle occurring to the AC
input current near the zero-crossings of the line voltage (crossover distortion). In this way the THD (Total
Harmonic Distortion) of the current is considerably reduced.
A major cause of this distortion is the inability of the system to transfer energy effectively when the instantaneous
line voltage is very low. This effect is magnified by the high-frequency filter capacitor placed after
the bridge rectifier, which retains some residual voltage that causes the diodes of the bridge rectifier to be
reverse-biased and the input current flow to temporarily stop.
Figure 22. THD optimization: standard TM PFC controller (left side) and L6562 (right side)
To overcome this issue the circuit embedded in the L6562 forces the PFC pre-regulator to process more
energy near the line voltage zero-crossings as compared to that commanded by the control loop. This will
result in both minimizing the time interval where energy transfer is lacking and fully discharging the highfrequency
filter capacitor after the bridge. The effect of the circuit is shown in figure 23, where the key
waveforms of a standard TM PFC controller are compared to those of the L6562.
Essentially, the circuit artificially increases the ON-time of the power switch with a positive offset added to

the output of the multiplier in the proximity of the line voltage zero-crossings. This offset is reduced as the
instantaneous line voltage increases, so that it becomes negligible as the line voltage moves toward the
top of the sinusoid.
To maximally benefit from the THD optimizer circuit, the high-frequency filter capacitor after the bridge rectifier
should be minimized, compatibly with EMI filtering needs. A large capacitance, in fact, introduces a
conduction dead-angle of the AC input current in itself - even with an ideal energy transfer by the PFC preregulator
- thus making the action of the optimizer circuit little effective.

Description
The SMAJ Transil series has been designed to
protect sensitive equipment against electrostatic
discharges according to IEC 61000-4-2, and
MIL STD 883, method 3015, and electrical over
stress according to IEC 61000-4-4 and 5. These
devices are generally used against surges below
400 W (10/1000 μs).
Planar technology makes these devices suitable
for high-end equipment and SMPS where low
leakage current and high junction temperature are
required to provide reliability and stability over
time.
SMAJ are packaged in SMA (SMA footprint in
accordance with IPC 7531 standard).

1. Pulse test : tp < 50 ms
2. To calculate maximum clamping voltage at other surge level,use the following formula: VCLmax = VCL - RD x (IPP - IPPappli)
where IPPappli is the surge current in the application
3. To calculate VBR or VCL versus junction temperature, use the following formulas:
VBR @ TJ = VBR @ 25°C x (1 + αT x (TJ – 25)),
VCL @ TJ = VCL @ 25°C x (1 + αT x (TJ – 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.

5 INTRODUCTION
In consumer electronics, an increasing demand has arisen for very high power monolithic audio amplifiers
able to match, with a low cost the performance obtained from the best discrete designs.
The task of realizing this linear integrated circuit in conventional bipolar technology is made extremely difficult
by the occurence of 2nd breakdown phenomenon. It limits the safe operating area (SOA) of the power
devices, and as a consequence, the maximum attainable output power, especially in presence of highly
reactive loads. Moreover, full exploitation of the SOA translates into a substantial increase in circuit and
layout complexity due to the need for sophisticated protection circuits.
To overcome these substantial drawbacks, the use of power MOS devices, which are immune from secondary
breakdown is highly desirable. The device described has therefore been developed in a mixed bipolar-
MOS high voltage technology called BCD 80.
5.1 Output Stage
The main design task one is confronted with while developing an integrated circuit as a power operational
amplifier, independently of the technology used, is that of realising the output stage. The solution shown
as a principle schematic by Fig 18 represents the DMOS unity-gain output buffer of the TDA7296.
This large-signal, high-power buffer must be capable of handling extremely high current and voltage levels
while maintaining acceptably low harmonic distortion and good behaviour over frequency response; moreover,
an accurate control of quiescent current is required.
A local linearizing feedback, provided by differential amplifier A, is used to fullfil the above requirements,
allowing a simple and effective quiescent current setting. Proper biasing of the power output transistors
alone is however not enough to guarantee the absence of crossover distortion. While a linearization of the
DC transfer characteristic of the stage is obtained, the dynamic behaviour of the system must be taken
into account.
A significant aid in keeping the distortion contributed by the final stage as low as possible is provided by
the compensation scheme, which exploits the direct connection of the Miller capacitor at the amplifier’s
output to introduce a local AC feedback path enclosing the output stage itself.
5.2 Protections
In designing a power IC, particular attention must be reserved to the circuits devoted to protection of the
device from short circuit or overload conditions.
Due to the absence of the 2nd breakdown phenomenon, the SOA of the power DMOS transistors is delimited
only by a maximum dissipation curve dependent on the duration of the applied stimulus.
In order to fully exploit the capabilities of the power transistors, the protection scheme implemented in this
device combines a conventional SOA protection circuit with a novel local temperature sensing technique
which " dynamically" controls the maximum dissipation.
Figure 18. Principle Schematic of a DMOS Unity-gain Buffer.

Figure 19. Turn ON/OFF Suggested Sequence
In addition to the overload protection described above, the device features a thermal shutdown circuit
which initially puts the device into a muting state (@ Tj = 145°C) and then into stand-by (@ Tj = 150°C).
Full protection against electrostatic discharges on every pin is included.
5.3 Other Features
The device is provided with both stand-by and mute functions, independently driven by two CMOS logic
compatible input pins.
The circuits dedicated to the switching on and off of the amplifier have been carefully optimized to avoid
any kind of uncontrolled audible transient at the output.
The sequence that we recommend during the ON/OFF transients is shown by Figure 19.
The application of figure 20 shows the possibility of using only one command for both st-by and mute functions.
On both the pins, the maximum applicable range corresponds to the operating supply voltage.

6 BRIDGE APPLICATION
Another application suggestion is the BRIDGE configuration, where two TDA7296 are used, as shown by
the schematic diagram.
In this application, the value of the load must not be lower than 8 Ohm for dissipation and current capability
reasons. A suitable field of application includes HI-FI/TV subwoofers realizations. The main advantages
offered by this solution are:
– High power performances with limited supply voltage level.
– Considerably high output power even with high load values (i.e. 16 Ohm).
The characteristics shown by figures 23 and 24, measured with loads respectively 8 Ohm and 16 Ohm.
With Rl= 8 Ohm, Vs = ±18V the maximum output power obtainable is 60W, while with Rl=16 Ohm, Vs =
±24V the maximum Pout is 60W.

NE556
SA556 - SE556
General-purpose dual bipolar timers
Features
■ Low turn-off time
■ Maximum operating frequency greater than
500 kHz
■ Timing from microseconds to hours
■ Operates in both astable and monostable
modes
■ Output can source or sink up to 200 mA
■ Adjustable duty cycle
■ TTL compatible
■ Temperature stability of 0.005% per °C
Description
The NE556, SA556 and SE556 dual monolithic
timing circuits are highly stable controllers
capable of producing accurate time delays or
oscillation. In the time delay mode of operation,
the time is precisely controlled by one external
resistor and capacitor. For a stable operation as
an oscillator, the free running frequency and the
duty cycle are both accurately controlled with two
external resistors and one capacitor.
The circuits may be triggered and reset on falling
waveforms, and the output structure can source
or sink up to 200 mA.

DESCRIPTION
The L293B and L293E are quad push-pull drivers
capable of delivering output currents to 1A per
channel. Each channel is controlled by a TTLcompatible
logic input and each pair of drivers (a
full bridge) is equipped with an inhibit input which
turns off all four transistors. A separate supply input
is provided for the logic so that it may be run
off a lower voltage to reduce dissipation.
Additionally, the L293E has external connection of
sensing resistors, for switchmode control.
The L293B and L293E are package in 16 and 20-
pin plastic DIPs respectively ; both use the four
center pins to conduct heat to the printed circuit
board.

1. All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages
where the zero reference level is the midpoint between VCC
+ and VCC
-.
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
3. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
4. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
5. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure
that the dissipation rating is not exceeded
6. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
7. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the
device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations
while the other pins are floating.
8. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly
to the ground through only one pin. This is done for all pins.

LM158, LM258, LM358
Low-power dual operational amplifiers
Datasheet - production data
Features
• Internally frequency-compensated
• Large DC voltage gain: 100 dB
• Wide bandwidth (unity gain): 1.1 MHz
(temperature compensated)
• Very low supply current per operator
essentially independent of supply voltage
• Low input bias current: 20 nA
(temperature compensated)
• Low input offset voltage: 2 mV
• Low input offset current: 2 nA
• Input common-mode voltage range includes
negative rails
• Differential input voltage range equal to the
power supply voltage
• Large output voltage swing 0 V to (VCC
+ -1.5 V)
Description
These circuits consist of two independent, high-gain, internally frequency-compensated op-amps, specifically designed to operate from a single power supply over a wide range of voltages. The low-power supply drain is independent of the magnitude of the power supply voltage.
Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits, which can now be more easily implemented in single power supply systems. For example, these circuits can be directly supplied with the standard +5 V, which is used in logic systems and will easily provide the required interface electronics with no additional power supply.
In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.

Output short-circuit duration (1)
1. Short-circuits from the output to VCC can cause excessive heating if VCC > 15 V. The maximum output
current is approximately 40 mA independent of the magnitude of VCC. Destructive dissipation can result
from simultaneous short circuits on all amplifiers.
Infinite
Iin Input current (2)
2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the
collector-base junction of the input PNP transistor becoming forward-biased and thereby acting as input
diode clamp. In addition to this diode action, there is NPN parasitic action on the IC chip. This transistor
action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large
overdrive) for the time during which an input is driven negative.
This is not destructive and normal output is restored for input voltages above -0.3 V.

2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output
so there is no change in the load on the input lines.
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V.
The upper end of the common-mode voltage range is VCC
+ - 1.5 V, but either or both inputs can go to +32 V without
damage.
4. Due to the proximity of external components, ensure that stray capacitance between these external parts does not cause
coupling. Typically, this can be detected because this type of capacitance increases at higher frequencies.

L78
Positive voltage regulator ICs
Datasheet - production data
Features
• Output current up to 1.5 A
• Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18;
24 V
• Thermal overload protection
• Short circuit protection
• Output transition SOA protection
• 2 % output voltage tolerance (A version)
• Guaranteed in extended temperature range
(A version)
Description
The L78 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
D²PAK and DPAK packages and several fixed
output voltages, making it useful in a wide range
of applications.
These regulators can provide local on-card
regulation, eliminating the distribution problems
associated with single point regulation. Each type
embeds internal current limiting, thermal shutdown
and safe area protection, making it
essentially indestructible. If adequate heat sinking
is provided, they can deliver over 1 A output
current. Although designed primarily as fixed
voltage regulators, these devices can be used
with external components to obtain adjustable
voltage and currents.

6 Application information
6.1 Design consideration
The L78 Series of fixed voltage regulators are designed with thermal overload protection
that shuts down the circuit when subjected to an excessive power overload condition,
internal short-circuit protection that limits the maximum current the circuit will pass, and
output transistor safe-area compensation that reduces the output short-circuit current as the
voltage across the pass transistor is increased. In many low current applications,
compensation capacitors are not required. However, it is recommended that the regulator
input be bypassed with capacitor if the regulator is connected to the power supply filter with
long lengths, or if the output load capacitance is large. An input bypass capacitor should be
selected to provide good high frequency characteristics to insure stable operation under all
load conditions. A 0.33 μF or larger tantalum, mylar or other capacitor having low internal
impedance at high frequencies should be chosen. The bypass capacitor should be mounted
with the shortest possible leads directly across the regulators input terminals. Normally good
construction techniques should be used to minimize ground loops and lead resistance drops
since the regulator has no external sense lead.
The addition of an operational amplifier allows adjustment to higher or intermediate values
while retaining regulation characteristics. The minimum voltage obtained with the
arrangement is 2 V greater than the regulator voltage.
The circuit of Figure 13 can be modified to provide supply protection against short circuit by
adding a short circuit sense resistor, RSC, and an additional PNP transistor. The current
sensing PNP must be able to handle the short circuit current of the three terminal regulator
Therefore a four ampere plastic power transistor is specified.
Figure 8. Fixed output regulator
1. Although no output capacitor is need for stability, it does improve transient response.
2. Required if regulator is located an appreciable distance from power supply filter.

34/58 DocID2143 Rev 32
Note: Application with high capacitance loads and an output voltage greater than 6 volts need an
external diode (see Figure 22 on page 31) to protect the device against input short circuit. In
this case the input voltage falls rapidly while the output voltage decrease slowly. The
capacitance discharges by means of the base-emitter junction of the series pass transistor
in the regulator. If the energy is sufficiently high, the transistor may be destroyed. The
external diode by-passes the current from the IC to ground.

2 Description
The STM32F405xx and STM32F407xx family is based on the high-performance ARM®
Cortex™-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4
core features a Floating point unit (FPU) single precision which supports all ARM singleprecision
data-processing instructions and data types. It also implements a full set of DSP
instructions and a memory protection unit (MPU) which enhances application security. The
Cortex-M4 core with FPU will be referred to as Cortex-M4F throughout this document.
The STM32F405xx and STM32F407xx family incorporates high-speed embedded
memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of
backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two
APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose
16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers.
a true random number generator (RNG). They also feature standard and advanced
communication interfaces.
• Up to three I2Cs
• Three SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals
can be clocked via a dedicated internal audio PLL or via an external clock to allow
synchronization.
• Four USARTs plus two UARTs
• An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the
ULPI),
• Two CANs
• An SDIO/MMC interface
• Ethernet and the camera interface available on STM32F407xx devices only.
New advanced peripherals include an SDIO, an enhanced flexible static memory control
(FSMC) interface (for devices offered in packages of 100 pins and more), a camera
interface for CMOS sensors. Refer to Table 2: STM32F405xx and STM32F407xx: features
and peripheral counts for the list of peripherals available on each part number.
The STM32F405xx and STM32F407xx family operates in the –40 to +105 °C temperature
range from a 1.8 to 3.6 V power supply. The supply voltage can drop to 1.7 V when the
device operates in the 0 to 70 °C temperature range using an external power supply
supervisor: refer to Section : Internal reset OFF. A comprehensive set of power-saving
mode allows the design of low-power applications.
The STM32F405xx and STM32F407xx family offers devices in various packages ranging
from 64 pins to 176 pins. The set of included peripherals changes with the device chosen.
These features make the STM32F405xx and STM32F407xx microcontroller family suitable
for a wide range of applications:
• Motor drive and application control
• Medical equipment
• Industrial applications: PLC, inverters, circuit breakers
• Printers, and scanners
• Alarm systems, video intercom, and HVAC
• Home audio appliances

STM32F405xx, STM32F407xx Description
2.1 Full compatibility throughout the family
The STM32F405xx and STM32F407xx are part of the STM32F4 family. They are fully pinto-
pin, software and feature compatible with the STM32F2xx devices, allowing the user to
try different memory densities, peripherals, and performances (FPU, higher frequency) for a
greater degree of freedom during the development cycle.
The STM32F405xx and STM32F407xx devices maintain a close compatibility with the
whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The
STM32F405xx and STM32F407xx, however, are not drop-in replacements for the
STM32F10xxx devices: the two families do not have the same power scheme, and so their
power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F40x
family remains simple as only a few pins are impacted.
Figure 4, Figure 3, Figure 2, and Figure 1 give compatible board designs between the
STM32F40x, STM32F2xxx, and STM32F10xxx families.

STM32F405xx, STM32F407xx Description
2.2.1 ARM® Cortex™-M4F core with embedded Flash and SRAM
The ARM Cortex-M4F processor is the latest generation of ARM processors for embedded
systems. It was developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced response to interrupts.
The ARM Cortex-M4F 32-bit RISC processor features exceptional code-efficiency,
delivering the high-performance expected from an ARM core in the memory size usually
associated with 8- and 16-bit devices.
The processor supports a set of DSP instructions which allow efficient signal processing and
complex algorithm execution.
Its single precision FPU (floating point unit) speeds up software development by using
metalanguage development tools, while avoiding saturation.
The STM32F405xx and STM32F407xx family is compatible with all ARM tools and software.
Figure 5 shows the general block diagram of the STM32F40x family.
Note: Cortex-M4F is binary compatible with Cortex-M3.
2.2.2 Adaptive real-time memory accelerator (ART Accelerator™)
The ART Accelerator™ is a memory accelerator which is optimized for STM32 industrystandard
ARM® Cortex™-M4F processors. It balances the inherent performance advantage
of the ARM Cortex-M4F over Flash memory technologies, which normally requires the
processor to wait for the Flash memory at higher frequencies.
To release the processor full 210 DMIPS performance at this frequency, the accelerator
implements an instruction prefetch queue and branch cache, which increases program
execution speed from the 128-bit Flash memory. Based on CoreMark benchmark, the
performance achieved thanks to the ART accelerator is equivalent to 0 wait state program
execution from Flash memory at a CPU frequency up to 168 MHz.
2.2.3 Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to memory to
prevent one task to accidentally corrupt the memory or resources used by any other active
task. This memory area is organized into up to 8 protected areas that can in turn be divided
up into 8 subareas. The protection area sizes are between 32 bytes and the whole 4
gigabytes of addressable memory.
The MPU is especially helpful for applications where some critical or certified code has to be
protected against the misbehavior of other tasks. It is usually managed by an RTOS (realtime
operating system). If a program accesses a memory location that is prohibited by the
MPU, the RTOS can detect it and take action. In an RTOS environment, the kernel can
dynamically update the MPU area setting, based on the process to be executed.
The MPU is optional and can be bypassed for applications that do not need it.
2.2.4 Embedded Flash memory
The STM32F40x devices embed a Flash memory of 512 Kbytes or 1 Mbytes available for
storing programs and data.
Description STM32F405xx, STM32F407xx
20/185 DocID022152 Rev 4
2.2.5 CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a software
signature during runtime, to be compared with a reference signature generated at link-time
and stored at a given memory location.
2.2.6 Embedded SRAM
All STM32F40x products embed:
• Up to 192 Kbytes of system SRAM including 64 Kbytes of CCM (core coupled memory)
data RAM
RAM memory is accessed (read/write) at CPU clock speed with 0 wait states.
• 4 Kbytes of backup SRAM
This area is accessible only from the CPU. Its content is protected against possible
unwanted write accesses, and is retained in Standby or VBAT mode.
2.2.7 Multi-AHB bus matrix
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, Ethernet, USB
HS) and the slaves (Flash memory, RAM, FSMC, AHB and APB peripherals) and ensures a
seamless and efficient operation even when several high-speed peripherals work
simultaneously.
DocID022152 Rev 4 21/185
STM32F405xx, STM32F407xx Description
Figure 6. Multi-AHB matrix
2.2.8 DMA controller (DMA)
The devices feature two general-purpose dual-port DMAs (DMA1 and DMA2) with 8
streams each. They are able to manage memory-to-memory, peripheral-to-memory and
memory-to-peripheral transfers. They feature dedicated FIFOs for APB/AHB peripherals,
support burst transfer and are designed to provide the maximum peripheral bandwidth
(AHB/APB).
The two DMA controllers support circular buffer management, so that no specific code is
needed when the controller reaches the end of the buffer. The two DMA controllers also
have a double buffering feature, which automates the use and switching of two memory
buffers without requiring any special code.
Each stream is connected to dedicated hardware DMA requests, with support for software
trigger on each stream. Configuration is made by software and transfer sizes between
source and destination are independent.
The DMA can be used with the main peripherals:
• SPI and I2S
• I2C
• USART
• General-purpose, basic and advanced-control timers TIMx
• DAC
• SDIO
• Camera interface (DCMI)
• ADC.

2.2.9 Flexible static memory controller (FSMC)
The FSMC is embedded in the STM32F405xx and STM32F407xx family. It has four Chip
Select outputs supporting the following modes: PCCard/Compact Flash, SRAM, PSRAM,
NOR Flash and NAND Flash.
Functionality overview:
• Write FIFO
• Maximum FSMC_CLK frequency for synchronous accesses is 60 MHz.
LCD parallel interface
The FSMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build costeffective
graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
2.2.10 Nested vectored interrupt controller (NVIC)
The STM32F405xx and STM32F407xx embed a nested vectored interrupt controller able to
manage 16 priority levels, and handle up to 82 maskable interrupt channels plus the 16
interrupt lines of the Cortex™-M4F.
• Closely coupled NVIC gives low-latency interrupt processing
• Interrupt entry vector table address passed directly to the core
• Allows early processing of interrupts
• Processing of late arriving, higher-priority interrupts
• Support tail chaining
• Processor state automatically saved
• Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
2.2.11 External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 23 edge-detector lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 140 GPIOs can be connected
to the 16 external interrupt lines.
2.2.12 Clocks and startup
On reset the 16 MHz internal RC oscillator is selected as the default CPU clock. The
16 MHz internal RC oscillator is factory-trimmed to offer 1% accuracy over the full
temperature range. The application can then select as system clock either the RC oscillator
or an external 4-26 MHz clock source. This clock can be monitored for failure. If a failure is
detected, the system automatically switches back to the internal RC oscillator and a
software interrupt is generated (if enabled). This clock source is input to a PLL thus allowing
to increase the frequency up to 168 MHz. Similarly, full interrupt management of the PLL
DocID022152 Rev 4 23/185
STM32F405xx, STM32F407xx Description
clock entry is available when necessary (for example if an indirectly used external oscillator
fails).
Several prescalers allow the configuration of the three AHB buses, the high-speed APB
(APB2) and the low-speed APB (APB1) domains. The maximum frequency of the three AHB
buses is 168 MHz while the maximum frequency of the high-speed APB domains is
84 MHz. The maximum allowed frequency of the low-speed APB domain is 42 MHz.
The devices embed a dedicated PLL (PLLI2S) which allows to achieve audio class
performance. In this case, the I2S master clock can generate all standard sampling
frequencies from 8 kHz to 192 kHz.
2.2.13 Boot modes
At startup, boot pins are used to select one out of three boot options:
• Boot from user Flash
• Boot from system memory
• Boot from embedded SRAM
The boot loader is located in system memory. It is used to reprogram the Flash memory by
using USART1 (PA9/PA10), USART3 (PC10/PC11 or PB10/PB11), CAN2 (PB5/PB13), USB
OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade).
2.2.14 Power supply schemes
• VDD = 1.8 to 3.6 V: external power supply for I/Os and the internal regulator (when
enabled), provided externally through VDD pins.
• VSSA, VDDA = 1.8 to 3.6 V: external analog power supplies for ADC, DAC, Reset
blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.
• VBAT = 1.65 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and
backup registers (through power switch) when VDD is not present.
Refer to Figure 21: Power supply scheme for more details.
Note: VDD/VDDA minimum value of 1.7 V is obtained when the device operates in reduced
temperature range, and with the use of an external power supply supervisor (refer to
Section : Internal reset OFF).
Refer to Table 2 in order to identify the packages supporting this option.
2.2.15 Power supply supervisor
Internal reset ON
On packages embedding the PDR_ON pin, the power supply supervisor is enabled by
holding PDR_ON high. On all other packages, the power supply supervisor is always
enabled.
The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry. At power-on, POR/PDR is always active and
ensures proper operation starting from 1.8 V. After the 1.8 V POR threshold level is
reached, the option byte loading process starts, either to confirm or modify default BOR
threshold levels, or to disable BOR permanently. Three BOR thresholds are available
through option bytes. The device remains in reset mode when VDD is below a specified
threshold, VPOR/PDR or VBOR, without the need for an external reset circuit.
Description STM32F405xx, STM32F407xx
24/185 DocID022152 Rev 4
The device also features an embedded programmable voltage detector (PVD) that monitors
the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be
generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is
higher than the VPVD threshold. The interrupt service routine can then generate a warning
message and/or put the MCU into a safe state. The PVD is enabled by software.
Internal reset OFF
This feature is available only on packages featuring the PDR_ON pin. The internal power-on
reset (POR) / power-down reset (PDR) circuitry is disabled with the PDR_ON pin.
An external power supply supervisor should monitor VDD and should maintain the device in
reset mode as long as VDD is below a specified threshold. PDR_ON should be connected to
this external power supply supervisor. Refer to Figure 7: Power supply supervisor
interconnection with internal reset OFF.
Figure 7. Power supply supervisor interconnection with internal reset OFF
1. PDR = 1.7 V for reduce temperature range; PDR = 1.8 V for all temperature range.
The VDD specified threshold, below which the device must be maintained under reset, is
1.8 V (see Figure 7). This supply voltage can drop to 1.7 V when the device operates in the
0 to 70 °C temperature range.
A comprehensive set of power-saving mode allows to design low-power applications.
When the internal reset is OFF, the following integrated features are no more supported:
• The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled
• The brownout reset (BOR) circuitry is disabled
• The embedded programmable voltage detector (PVD) is disabled
• VBAT functionality is no more available and VBAT pin should be connected to VDD
All packages, except for the LQFP64 and LQFP100, allow to disable the internal reset
through the PDR_ON signal.

2.2.16 Voltage regulator
The regulator has four operating modes:
• Regulator ON
– Main regulator mode (MR)
– Low power regulator (LPR)
– Power-down
• Regulator OFF
Regulator ON
On packages embedding the BYPASS_REG pin, the regulator is enabled by holding
BYPASS_REG low. On all other packages, the regulator is always enabled.
There are three power modes configured by software when regulator is ON:
• MR is used in the nominal regulation mode (With different voltage scaling in Run)
In Main regulator mode (MR mode), different voltage scaling are provided to reach the
best compromise between maximum frequency and dynamic power consumption.
Refer to Table 14: General operating conditions.
• LPR is used in the Stop modes
The LP regulator mode is configured by software when entering Stop mode.
• Power-down is used in Standby mode.
The Power-down mode is activated only when entering in Standby mode. The regulator
output is in high impedance and the kernel circuitry is powered down, inducing zero
consumption. The contents of the registers and SRAM are lost)

Regulator OFF
This feature is available only on packages featuring the BYPASS_REG pin. The regulator is
disabled by holding BYPASS_REG high. The regulator OFF mode allows to supply
externally a V12 voltage source through VCAP_1 and VCAP_2 pins.
Since the internal voltage scaling is not manage internally, the external voltage value must
be aligned with the targetted maximum frequency. Refer to Table 14: General operating

When the regulator is OFF, there is no more internal monitoring on V12. An external power
supply supervisor should be used to monitor the V12 of the logic power domain. PA0 pin
should be used for this purpose, and act as power-on reset on V12 power domain.
In regulator OFF mode the following features are no more supported:
• PA0 cannot be used as a GPIO pin since it allows to reset a part of the V12 logic power
domain which is not reset by the NRST pin.
• As long as PA0 is kept low, the debug mode cannot be used under power-on reset. As
a consequence, PA0 and NRST pins must be managed separately if the debug
connection under reset or pre-reset is required.

STM32F405xx, STM32F407xx Description
The following conditions must be respected:
• VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection
between power domains.
• If the time for VCAP_1 and VCAP_2 to reach V12 minimum value is faster than the time for
VDD to reach 1.8 V, then PA0 should be kept low to cover both conditions: until VCAP_1
and VCAP_2 reach V12 minimum value and until VDD reaches 1.8 V (see Figure 10).
• Otherwise, if the time for VCAP_1 and VCAP_2 to reach V12 minimum value is slower
than the time for VDD to reach 1.8 V, then PA0 could be asserted low externally (see
Figure 11).
• If VCAP_1 and VCAP_2 go below V12 minimum value and VDD is higher than 1.8 V, then
a reset must be asserted on PA0 pin.
Note: The minimum value of V12 depends on the maximum frequency targeted in the application
(see Table 14: General operating conditions).

2.2.18 Real-time clock (RTC), backup SRAM and backup registers
The backup domain of the STM32F405xx and STM32F407xx includes:
• The real-time clock (RTC)
• 4 Kbytes of backup SRAM
• 20 backup registers
The real-time clock (RTC) is an independent BCD timer/counter. Dedicated registers contain
the second, minute, hour (in 12/24 hour), week day, date, month, year, in BCD (binarycoded
decimal) format. Correction for 28, 29 (leap year), 30, and 31 day of the month are
performed automatically. The RTC provides a programmable alarm and programmable
periodic interrupts with wakeup from Stop and Standby modes. The sub-seconds value is
also available in binary format.
It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal low-power
RC oscillator or the high-speed external clock divided by 128. The internal low-speed RC

STM32F405xx, STM32F407xx Description
has a typical frequency of 32 kHz. The RTC can be calibrated using an external 512 Hz
output to compensate for any natural quartz deviation.
Two alarm registers are used to generate an alarm at a specific time and calendar fields can
be independently masked for alarm comparison. To generate a periodic interrupt, a 16-bit
programmable binary auto-reload downcounter with programmable resolution is available
and allows automatic wakeup and periodic alarms from every 120 μs to every 36 hours.
A 20-bit prescaler is used for the time base clock. It is by default configured to generate a
time base of 1 second from a clock at 32.768 kHz.
The 4-Kbyte backup SRAM is an EEPROM-like memory area. It can be used to store data
which need to be retained in VBAT and standby mode. This memory area is disabled by
default to minimize power consumption (see Section 2.2.19: Low-power modes). It can be
enabled by software.
The backup registers are 32-bit registers used to store 80 bytes of user application data
when VDD power is not present. Backup registers are not reset by a system, a power reset,
or when the device wakes up from the Standby mode (see Section 2.2.19: Low-power
modes).
Additional 32-bit registers contain the programmable alarm subseconds, seconds, minutes,
hours, day, and date.
Like backup SRAM, the RTC and backup registers are supplied through a switch that is
powered either from the VDD supply when present or from the VBAT pin.
2.2.19 Low-power modes
The STM32F405xx and STM32F407xx support three low-power modes to achieve the best
compromise between low power consumption, short startup time and available wakeup
sources:
• Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
• Stop mode
The Stop mode achieves the lowest power consumption while retaining the contents of
SRAM and registers. All clocks in the V12 domain are stopped, the PLL, the HSI RC
and the HSE crystal oscillators are disabled. The voltage regulator can also be put
either in normal or in low-power mode.
The device can be woken up from the Stop mode by any of the EXTI line (the EXTI line
source can be one of the 16 external lines, the PVD output, the RTC alarm / wakeup /
tamper / time stamp events, the USB OTG FS/HS wakeup or the Ethernet wakeup).
• Standby mode
The Standby mode is used to achieve the lowest power consumption. The internal
voltage regulator is switched off so that the entire V12 domain is powered off. The PLL,
the HSI RC and the HSE crystal oscillators are also switched off. After entering
Description STM32F405xx, STM32F407xx
30/185 DocID022152 Rev 4
Standby mode, the SRAM and register contents are lost except for registers in the
backup domain and the backup SRAM when selected.
The device exits the Standby mode when an external reset (NRST pin), an IWDG reset,
a rising edge on the WKUP pin, or an RTC alarm / wakeup / tamper /time stamp event
occurs.
The standby mode is not supported when the embedded voltage regulator is bypassed
and the V12 domain is controlled by an external power.
2.2.20 VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery, an external
supercapacitor, or from VDD when no external battery and an external supercapacitor are
present.
VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC, the backup registers and the backup SRAM.
Note: When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation.
When PDR_ON pin is not connected to VDD (internal reset OFF), the VBAT functionality is no
more available and VBAT pin should be connected to VDD.
2.2.21 Timers and watchdogs
The STM32F405xx and STM32F407xx devices include two advanced-control timers, eight
general-purpose timers, two basic timers and two watchdog timers.
All timer counters can be frozen in debug mode.
Table 4 compares the features of the advanced-control, general-purpose and basic timers.

STM32F405xx, STM32F407xx Description
Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
• Input capture
• Output compare
• PWM generation (edge- or center-aligned modes)
• One-pulse mode output
If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-
100%).
The advanced-control timer can work together with the TIMx timers via the Timer Link
feature for synchronization or event chaining.
TIM1 and TIM8 support independent DMA request generation.

General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32F40x devices
(see Table 4 for differences).
• TIM2, TIM3, TIM4, TIM5
The STM32F40x include 4 full-featured general-purpose timers: TIM2, TIM5, TIM3,
and TIM4.The TIM2 and TIM5 timers are based on a 32-bit auto-reload
up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are based on a 16-
bit auto-reload up/downcounter and a 16-bit prescaler. They all feature 4 independent
channels for input capture/output compare, PWM or one-pulse mode output. This gives
up to 16 input capture/output compare/PWMs on the largest packages.
The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the
other general-purpose timers and the advanced-control timers TIM1 and TIM8 via the
Timer Link feature for synchronization or event chaining.
Any of these general-purpose timers can be used to generate PWM outputs.
TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are
capable of handling quadrature (incremental) encoder signals and the digital outputs
from 1 to 4 hall-effect sensors.
• TIM9, TIM10, TIM11, TIM12, TIM13, and TIM14
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10, TIM11, TIM13, and TIM14 feature one independent channel, whereas TIM9
and TIM12 have two independent channels for input capture/output compare, PWM or
one-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5
full-featured general-purpose timers. They can also be used as simple time bases.
Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger and waveform generation. They can also be
used as a generic 16-bit time base.
TIM6 and TIM7 support independent DMA request generation.
Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes.
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from
the main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.
DocID022152 Rev 4 33/185
STM32F405xx, STM32F407xx Description
SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
downcounter. It features:
• A 24-bit downcounter
• Autoreload capability
• Maskable system interrupt generation when the counter reaches 0
• Programmable clock source.
2.2.22 Inter-integrated circuit interface (I²C)
Up to three I²C bus interfaces can operate in multimaster and slave modes. They can
support the Standard-mode (up to 100 kHz) and Fast-mode (up to 400 kHz) . They support
the 7/10-bit addressing mode and the 7-bit dual addressing mode (as slave). A hardware
CRC generation/verification is embedded.
They can be served by DMA and they support SMBus 2.0/PMBus.
2.2.23 Universal synchronous/asynchronous receiver transmitters (USART)
The STM32F405xx and STM32F407xx embed four universal synchronous/asynchronous
receiver transmitters (USART1, USART2, USART3 and USART6) and two universal
asynchronous receiver transmitters (UART4 and UART5).
These six interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to
communicate at speeds of up to 10.5 Mbit/s. The other available interfaces communicate at
up to 5.25 Mbit/s.
USART1, USART2, USART3 and USART6 also provide hardware management of the CTS
and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication
capability. All interfaces can be served by the DMA controller.
Description STM32F405xx, STM32F407xx
34/185 DocID022152 Rev 4
2.2.24 Serial peripheral interface (SPI)
The STM32F40x feature up to three SPIs in slave and master modes in full-duplex and
simplex communication modes. SPI1 can communicate at up to 42 Mbits/s, SPI2 and SPI3
can communicate at up to 21 Mbit/s. The 3-bit prescaler gives 8 master mode frequencies
and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification
supports basic SD Card/MMC modes. All SPIs can be served by the DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
2.2.25 Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be
operated in master or slave mode, in full duplex and half-duplex communication modes, and
can be configured to operate with a 16-/32-bit resolution as an input or output channel.
Audio sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of
the I2S interfaces is/are configured in master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency.
All I2Sx can be served by the DMA controller.
2.2.26 Audio PLL (PLLI2S)
The devices feature an additional dedicated PLL for audio I2S application. It allows to
achieve error-free I2S sampling clock accuracy without compromising on the CPU
performance, while using USB peripherals.

STM32F405xx, STM32F407xx Description
The PLLI2S configuration can be modified to manage an I2S sample rate change without
disabling the main PLL (PLL) used for CPU, USB and Ethernet interfaces.
The audio PLL can be programmed with very low error to obtain sampling rates ranging
from 8 KHz to 192 KHz.
In addition to the audio PLL, a master clock input pin can be used to synchronize the I2S
flow with an external PLL (or Codec output).
2.2.27 Secure digital input/output interface (SDIO)
An SD/SDIO/MMC host interface is available, that supports MultiMediaCard System
Specification Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit.
The interface allows data transfer at up to 48 MHz, and is compliant with the SD Memory
Card Specification Version 2.0.
The SDIO Card Specification Version 2.0 is also supported with two different databus
modes: 1-bit (default) and 4-bit.
The current version supports only one SD/SDIO/MMC4.2 card at any one time and a stack
of MMC4.1 or previous.
In addition to SD/SDIO/MMC, this interface is fully compliant with the CE-ATA digital
protocol Rev1.1.
2.2.28 Ethernet MAC interface with dedicated DMA and IEEE 1588 support
Peripheral available only on the STM32F407xx devices.
The STM32F407xx devices provide an IEEE-802.3-2002-compliant media access controller
(MAC) for ethernet LAN communications through an industry-standard mediumindependent
interface (MII) or a reduced medium-independent interface (RMII). The
STM32F407xx requires an external physical interface device (PHY) to connect to the
physical LAN bus (twisted-pair, fiber, etc.). the PHY is connected to the STM32F407xx MII
port using 17 signals for MII or 9 signals for RMII, and can be clocked using the 25 MHz
(MII) from the STM32F407xx.
The STM32F407xx includes the following features:
• Supports 10 and 100 Mbit/s rates
• Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM
and the descriptors (see the STM32F40x reference manual for details)
• Tagged MAC frame support (VLAN support)
• Half-duplex (CSMA/CD) and full-duplex operation

group addresses)
• 32-bit status code for each transmitted or received frame
• Internal FIFOs to buffer transmit and receive frames. The transmit FIFO and the
receive FIFO are both 2 Kbytes.
• Supports hardware PTP (precision time protocol) in accordance with IEEE 1588 2008
(PTP V2) with the time stamp comparator connected to the TIM2 input
• Triggers interrupt when system time becomes greater than target time
Description STM32F405xx, STM32F407xx
36/185 DocID022152 Rev 4
2.2.29 Controller area network (bxCAN)
The two CANs are compliant with the 2.0A and B (active) specifications with a bitrate up to 1
Mbit/s. They can receive and transmit standard frames with 11-bit identifiers as well as
extended frames with 29-bit identifiers. Each CAN has three transmit mailboxes, two receive
FIFOS with 3 stages and 28 shared scalable filter banks (all of them can be used even if one
CAN is used). 256 bytes of SRAM are allocated for each CAN.
2.2.30 Universal serial bus on-the-go full-speed (OTG_FS)
The STM32F405xx and STM32F407xx embed an USB OTG full-speed device/host/OTG
peripheral with integrated transceivers. The USB OTG FS peripheral is compliant with the
USB 2.0 specification and with the OTG 1.0 specification. It has software-configurable
endpoint setting and supports suspend/resume. The USB OTG full-speed controller
requires a dedicated 48 MHz clock that is generated by a PLL connected to the HSE
oscillator. The major features are:
• Combined Rx and Tx FIFO size of 320 × 35 bits with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 4 bidirectional endpoints
• 8 host channels with periodic OUT support
• HNP/SNP/IP inside (no need for any external resistor)
• For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected
2.2.31 Universal serial bus on-the-go high-speed (OTG_HS)
The STM32F405xx and STM32F407xx devices embed a USB OTG high-speed (up to
480 Mb/s) device/host/OTG peripheral. The USB OTG HS supports both full-speed and
high-speed operations. It integrates the transceivers for full-speed operation (12 MB/s) and
features a UTMI low-pin interface (ULPI) for high-speed operation (480 MB/s). When using
the USB OTG HS in HS mode, an external PHY device connected to the ULPI is required.
The USB OTG HS peripheral is compliant with the USB 2.0 specification and with the OTG
1.0 specification. It has software-configurable endpoint setting and supports
suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock
that is generated by a PLL connected to the HSE oscillator.
The major features are:
• Combined Rx and Tx FIFO size of 1 Kbit × 35 with dynamic FIFO sizing
• Supports the session request protocol (SRP) and host negotiation protocol (HNP)
• 6 bidirectional endpoints
• 12 host channels with periodic OUT support
• Internal FS OTG PHY support
• External HS or HS OTG operation supporting ULPI in SDR mode. The OTG PHY is
connected to the microcontroller ULPI port through 12 signals. It can be clocked using
the 60 MHz output.
• Internal USB DMA
• HNP/SNP/IP inside (no need for any external resistor)
• for OTG/Host modes, a power switch is needed in case bus-powered devices are
connected
DocID022152 Rev 4 37/185
STM32F405xx, STM32F407xx Description
2.2.32 Digital camera interface (DCMI)
The camera interface is not available in STM32F405xx devices.
STM32F407xx products embed a camera interface that can connect with camera modules
and CMOS sensors through an 8-bit to 14-bit parallel interface, to receive video data. The
camera interface can sustain a data transfer rate up to 54 Mbyte/s at 54 MHz. It features:
• Programmable polarity for the input pixel clock and synchronization signals
• Parallel data communication can be 8-, 10-, 12- or 14-bit
• Supports 8-bit progressive video monochrome or raw bayer format, YCbCr 4:2:2
progressive video, RGB 565 progressive video or compressed data (like JPEG)
• Supports continuous mode or snapshot (a single frame) mode
• Capability to automatically crop the image
2.2.33 Random number generator (RNG)
All STM32F405xx and STM32F407xx products embed an RNG that delivers 32-bit random
numbers generated by an integrated analog circuit.
2.2.34 General-purpose input/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)
or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
alternate functions. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
The I/O configuration can be locked if needed by following a specific sequence in order to
avoid spurious writing to the I/Os registers.
Fast I/O handling allowing maximum I/O toggling up to 84 MHz.
2.2.35 Analog-to-digital converters (ADCs)
Three 12-bit analog-to-digital converters are embedded and each ADC shares up to 16
external channels, performing conversions in the single-shot or scan mode. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:
• Simultaneous sample and hold
• Interleaved sample and hold
The ADC can be served by the DMA controller. An analog watchdog feature allows very
precise monitoring of the converted voltage of one, some or all selected channels. An
interrupt is generated when the converted voltage is outside the programmed thresholds.
To synchronize A/D conversion and timers, the ADCs could be triggered by any of TIM1,
TIM2, TIM3, TIM4, TIM5, or TIM8 timer.
2.2.36 Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 1.8 V and 3.6 V. The temperature sensor is internally
Description STM32F405xx, STM32F407xx
38/185 DocID022152 Rev 4
connected to the ADC1_IN16 input channel which is used to convert the sensor output
voltage into a digital value.
As the offset of the temperature sensor varies from chip to chip due to process variation, the
internal temperature sensor is mainly suitable for applications that detect temperature
changes instead of absolute temperatures. If an accurate temperature reading is needed,
then an external temperature sensor part should be used.
2.2.37 Digital-to-analog converter (DAC)
The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs.
This dual digital Interface supports the following features:
• two DAC converters: one for each output channel
• 8-bit or 12-bit monotonic output
• left or right data alignment in 12-bit mode
• synchronized update capability
• noise-wave generation
• triangular-wave generation
• dual DAC channel independent or simultaneous conversions
• DMA capability for each channel
• external triggers for conversion
• input voltage reference VREF+
Eight DAC trigger inputs are used in the device. The DAC channels are triggered through
the timer update outputs that are also connected to different DMA streams.
2.2.38 Serial wire JTAG debug port (SWJ-DP)
The ARM SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
Debug is performed using 2 pins only instead of 5 required by the JTAG (JTAG pins could
be re-use as GPIO with alternate function): the JTAG TMS and TCK pins are shared with
SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to
switch between JTAG-DP and SW-DP.
2.2.39 Embedded Trace Macrocell™
The ARM Embedded Trace Macrocell provides a greater visibility of the instruction and data
flow inside the CPU core by streaming compressed data at a very high rate from the
STM32F40x through a small number of ETM pins to an external hardware trace port
analyser (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or
any other high-speed channel. Real-time instruction and data flow activity can be recorded
and then formatted for display on the host computer that runs the debugger software. TPA
hardware is commercially available from common development tool vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.

1. Function availability depends on the chosen device.
2. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These I/Os must not be used as a current source (e.g. to drive an LED).
3. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after
reset (because these registers are not reset by the main reset). For details on how to manage these I/Os, refer to the RTC

5 Electrical characteristics
5.1 Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
5.1.1 Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).
5.1.2 Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V (for the
1.8 V ≤ VDD ≤ 3.6 V voltage range). They are given only as design guidelines and are not
tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2Σ).
5.1.3 Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.
5.1.4 Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 19.
5.1.5 Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 20.

Figure 21. Power supply scheme
1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These
capacitors must be placed as close as possible to, or below, the appropriate pins on the underside of the
PCB to ensure the good functionality of the device.
2. To connect BYPASS_REG and PDR_ON pins, refer to Section 2.2.16: Voltage regulator and Table 2.2.15:
Power supply supervisor.
3. The two 2.2 μF ceramic capacitors should be replaced by two 100 nF decoupling capacitors when the
voltage regulator is OFF.
4. The 4.7 μF ceramic capacitor must be connected to one of the VDD pin.
5. VDDA=VDD and VSSA=VSS.

Figure 29. Typical VBAT current consumption (LSE and RTC ON/backup RAM ON)
I/O system current consumption
The current consumption of the I/O system has two components: static and dynamic.
I/O static current consumption
All the I/Os used as inputs with pull-up generate current consumption when the pin is
externally held low. The value of this current consumption can be simply computed by using
the pull-up/pull-down resistors values given in Table 47: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
Additional I/O current consumption is due to I/Os configured as inputs if an intermediate
voltage level is externally applied. This current consumption is caused by the input Schmitt
trigger circuits used to discriminate the input value. Unless this specific configuration is
required by the application, this supply current consumption can be avoided by configuring
these I/Os in analog mode. This is notably the case of ADC input pins which should be
configured as analog inputs.
Caution: Any floating input pin can also settle to an intermediate voltage level or switch inadvertently,
as a result of external electromagnetic noise. To avoid current consumption related to
floating pins, they must either be configured in analog mode, or forced internally to a definite
digital value. This can be done either by using pull-up/down resistors or by configuring the
pins in output mode.
I/O dynamic current consumption
In addition to the internal peripheral current consumption measured previously (see
Table 27: Peripheral current consumption), the I/Os used by an application also contribute
to the current consumption. When an I/O pin switches, it uses the current from the MCU

On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 27. The MCU is placed
under the following conditions:
• At startup, all I/O pins are configured as analog pins by firmware.
• All peripherals are disabled unless otherwise mentioned
• The code is running from Flash memory and the Flash memory access time is equal to
5 wait states at 168 MHz.
• The code is running from Flash memory and the Flash memory access time is equal to
4 wait states at 144 MHz, and the power scale mode is set to 2.
• ART accelerator and Cache off.
• The given value is calculated by measuring the difference of current consumption
– with all peripherals clocked off
– with one peripheral clocked on (with only the clock applied)
• When the peripherals are enabled: HCLK is the system clock, fPCLK1 = fHCLK/4, and
fPCLK2 = fHCLK/2.
• The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise
specified.

For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 32). CL1 and CL2 are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the
series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF
can be used as a rough estimate of the combined pin and board capacitance) when sizing
CL1 and CL2.
Note: For information on electing the crystal, refer to the application note AN2867 “Oscillator

Equation 2
Equation 2 allows to calculate the increment step (INCSTEP):
fVCO_OUT must be expressed in MHz.
With a modulation depth (md) = ±2 % (4 % peak to peak), and PLLN = 240 (in MHz):
An amplitude quantization error may be generated because the linear modulation profile is
obtained by taking the quantized values (rounded to the nearest integer) of MODPER and
INCSTEP. As a result, the achieved modulation depth is quantized. The percentage
quantized modulation depth is given by the following formula:
As a result:
Figure 35 and Figure 36 show the main PLL output clock waveforms in center spread and
down spread modes, where:
F0 is fPLL_OUT nominal.
Tmode is the modulation period.
md is the modulation depth.

Susceptibility tests are performed on a sample basis during device characterization.
Functional EMS (electromagnetic susceptibility)
While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
• Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
• FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS
through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant
with the IEC 61000-4-4 standard.

STM32F405xx, STM32F407xx Electrical characteristics
A device reset allows normal operations to be resumed.
The test results are given in Table 42. They are based on the EMS levels and classes
defined in application note AN1709.
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
• Corrupted program counter
• Unexpected reset
• Critical Data corruption (control registers...)
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application,
executing EEMBC? code, is running. This emission test is compliant with SAE IEC61967-2
standard which specifies the test board and the pin loading.

5.3.14 Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.
Static latchup
Two complementary static tests are required on six parts to assess the latchup
performance:
• A supply overvoltage is applied to each power supply pin
• A current injection is applied to each input, output and configurable I/O pin
These tests are compliant with EIA/JESD 78A IC latchup standard.

5.3.15 I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (>5
LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out of
5 uA/+0 uA range), or other functional failure (for example reset, oscillator frequency
deviation).
Negative induced leakage current is caused by negative injection and positive induced
leakage current by positive injection.
The test results are given in Table 46.

STM32F405xx, STM32F407xx Electrical characteristics
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 5.2. In particular:
• The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 12).
• The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
IVSS (see Table 12).
Output voltage levels
Unless otherwise specified, the parameters given in Table 48 are derived from tests
performed under ambient temperature and VDD supply voltage conditions summarized in
Table 14. All I/Os are CMOS and TTL compliant.

1. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited
amount of current (3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited: the speed
should not exceed 2 MHz with a maximum load of 30 pF and these I/Os must not be used as a current
source (e.g. to drive an LED).

clock.
3. The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the
undefined region of the falling edge of SCL.
4. The maximum data hold time has only to be met if the interface does not stretch the low period of SCL
signal.

SPI interface characteristics
Unless otherwise specified, the parameters given in Table 55 for SPI are derived from tests
performed under the ambient temperature, fPCLKx frequency and VDD supply voltage
conditions summarized in Table 14 with the following configuration:
• Output speed is set to OSPEEDRy[1:0] = 10
• Capacitive load C = 30 pF
• Measurement points are done at CMOS levels: 0.5 VDD
Refer to Section 5.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics (NSS, SCK, MOSI, MISO).
Table 54. SCL frequency (fPCLK1= 42 MHz.,VDD = 3.3 V)(1)(2)
1. RP = External pull-up resistance, fSCL = I2C speed,
2. For speeds around 200 kHz, the tolerance on the achieved speed is of ±5%. For other speed ranges, the
tolerance on the achieved speed ±2%. These variations depend on the accuracy of the external
components used to design the application.

I2S interface characteristics
Unless otherwise specified, the parameters given in Table 56 for the i2S interface are
derived from tests performed under the ambient temperature, fPCLKx frequency and VDD
supply voltage conditions summarized in Table 14, with the following configuration:
• Output speed is set to OSPEEDRy[1:0] = 10
• Capacitive load C = 30 pF
• Measurement points are done at CMOS levels: 0.5 VDD
Refer to Section 5.3.16: I/O port characteristics for more details on the input/output alternate
function characteristics (CK, SD, WS).
Note: Refer to the I2S section of RM0090 reference manual for more details on the sampling
frequency (FS). fMCK, fCK, and DCK values reflect only the digital peripheral behavior. The
value of these parameters might be slightly impacted by the source clock accuracy. DCK
depends mainly on the value of ODD bit. The digital contribution leads to a minimum value
of I2SDIV / (2 x I2SDIV + ODD) and a maximum value of (I2SDIV + ODD) / (2 x I2SDIV +
ODD). FS maximum value is supported for each mode/condition.

Note: ADC accuracy vs. negative injection current: injecting a negative current on any analog
input pins should be avoided as this significantly reduces the accuracy of the conversion
being performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in

2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (roughly 5 pF). A high Cparasitic value downgrades conversion accuracy. To remedy this,
fADC should be reduced.

General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 52 or Figure 53,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.
Figure 52. Power supply and reference decoupling (VREF+ not connected to VDDA)
1. VREF+ and VREF– inputs are both available on UFBGA176. VREF+ is also available on LQFP100, LQFP144,
and LQFP176. When VREF+ and VREF– are not available, they are internally connected to VDDA and VSSA.

6.2 Thermal characteristics
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max x ΘJA)
Where:
• TA max is the maximum ambient temperature in °C,
• ΘJA is the package junction-to-ambient thermal resistance, in °C/W,
• PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
• PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = Σ (VOL × IOL) + Σ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.

TL494 Pulse-Width-Modulation Control Circuits
Check for Samples: TL494
1FEATURES DESCRIPTION
• Complete PWM Power-Control Circuitry The TL494 device incorporates all the functions
• Uncommitted Outputs for 200-mA Sink or required in the construction of a pulse-width- modulation (PWM) control circuit on a single chip.
Source Current Designed primarily for power-supply control, this
• Output Control Selects Single-Ended or device offers the flexibility to tailor the power-supply
Push-Pull Operation control circuitry to a specific application.
• Internal Circuitry Prohibits Double Pulse at The TL494 device contains two error amplifiers, an
Either Output on-chip adjustable oscillator, a dead-time control
• Variable Dead Time Provides Control Over (DTC) comparator, a pulse-steering control flip-flop, a
Total Range 5-V, 5%-precision regulator, and output-control
circuits.
• Internal Regulator Provides a Stable 5-V
Reference Supply With 5% Tolerance The error amplifiers exhibit a common-mode voltage
• Circuit Architecture Allows Easy range from –0.3 V to VCC – 2 V. The dead-time Synchronization control comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator
can be bypassed by terminating RT to the reference
output and providing a sawtooth input to CT, or it can
drive the common circuits in synchronous multiple-rail
power supplies.
The uncommitted output transistors provide either
common-emitter or emitter-follower output capability.
The TL494 device provides for push-pull or singleended
output operation, which can be selected
through the output-control function. The architecture
of this device prohibits the possibility of either output
being pulsed twice during push-pull operation.
The TL494C device is characterized for operation
from 0°C to 70°C. The TL494I device is characterized
for operation from –40°C to 85°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

−> Attention ! les relais à semi-conducteurs ne procurent pas d'isolation galvanique entre le réseau et la charge. Ils doivent être utilisés
associés à un disjoncteur avec propriété de sectionnement ou similaire, afin d'assurer un sectionnement fiable en amont de la ligne dans
l'hypothèse d'une défaillance et pour tous les cas où le relais doit être isolé du réseau (maintenance ; non utilisation sur une longue durée...).

Protection /Protection :
−> La protection d'un relais statique contre les court-circuits de la charge peut être faite par fusibles rapides avec des I2t = 1/2 I2t
du relais . Un test en laboratoire a été effectué sur les fusibles de marque FERRAZ.
Une protection par MCB ( disjoncteurs modulaires miniatures) est aussi possible.
Voir notre note application ( protection SSR) et utiliser des relais avec I2t >5000A2s
To protect the SSR against a short-circuit of the load , use a fuse with a I2t value = 1/2 I2t value specified page 2.
A test has been made with FERRAZ fuses .
It is possible to protect SSR by MCB ( miniature circuit breaker).
In this case, see application note ( SSR protection) and use a SSR with high I2t value (5000A2s minimum).
EMC :
−> Immunité : Nous spécifions dans nos notices le niveau d'immunité de nos produits selon les normes essentielles pour ce type de
produit, c'est à dire EN61000-4-4 &5.
Immunity :
We give in our data-sheets the immunity level of our SSRs according to the main standards for these products: EN61000-4-4 &5.
−> Emission: Nos relais statiques sont principalement conçus et conformes pour la classe d'appareils A (Industrie).
L'utilisation du produit dans des environnements domestiques peut amener l'utilisateur à employer des moyens d'atténuation
supplémentaires. En effet, les relais statiques sont des dispositifs complexes qui doivent être interconnectés avec d'autres materiels
(charges, cables, etc) pour former un système. Etant donné que les autres materiels ou interconnexions ne sont pas de la responsabilité
de celduc, il est de la responsabilité du réalisateur du système de s'assurer que les systèmes contenant des relais statiques satisfont
aux prescriptions de toutes les règles et règlements applicables au niveau des systèmes.
Consulter celduc qui peut vous conseiller ou réaliser des essais dans son laboratoire sur votre application.
Emission: celduc SSRs are mainly designed in compliance with standards for class A equipment (Industry).
Use of this product in domestic environments may cause radio interference. In this case the user may be required to employ
additionnal devices to reduce noise. SSRs are complex devices that must be interconnected with other equipment (loads, cables, etc.)
to form a system. Because the other equipment or the interconnections may not be under the control of celduc, it shall be the
responsability of the system integrator to ensure that systems containing SSRs comply with the requirement of any rules and
regulations applicable at the system level.
Consult celduc for advices. Tests can be preformed in our laboratory.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

________________General Description
The MAX3222/MAX3232/MAX3237/MAX3241 transceivers
have a proprietary low-dropout transmitter output
stage enabling true RS-232 performance from a
3.0V to 5.5V supply with a dual charge pump. The
devices require only four small 0.1μF external chargepump
capacitors. The MAX3222, MAX3232, and
MAX3241 are guaranteed to run at data rates of
120kbps while maintaining RS-232 output levels. The
MAX3237 is guaranteed to run at data rates of 250kbps
in the normal operating mode and 1Mbps in the
MegaBaud™ operating mode, while maintaining RS-232
output levels.
The MAX3222/MAX3232 have 2 receivers and 2
drivers. The MAX3222 features a 1μA shutdown mode
that reduces power consumption and extends battery
life in portable systems. Its receivers remain active in
shutdown mode, allowing external devices such as
modems to be monitored using only 1μA supply current.
The MAX3222 and MAX3232 are pin, package,
and functionally compatible with the industry-standard
MAX242 and MAX232, respectively.
The MAX3241 is a complete serial port (3 drivers/
5 receivers) designed for notebook and subnotebook
computers. The MAX3237 (5 drivers/3 receivers) is ideal
for fast modem applications. Both these devices feature
a shutdown mode in which all receivers can remain
active while using only 1μA supply current. Receivers R1
(MAX3237/MAX3241) and R2 (MAX3241) have extra outputs
in addition to their standard outputs. These extra
outputs are always active, allowing external devices
such as a modem to be monitored without forward biasing
the protection diodes in circuitry that may have VCC
completely removed.
The MAX3222, MAX3232, and MAX3241 are available
in space-saving TSSOP and SSOP packages.
