Description
STM32H742xI/G and STM32H743xI/G devices are based on the high-performance Arm®
Cortex®-M7 32-bit RISC core operating at up to 480 MHz. The Cortex® -M7 core features a
floating point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and
single-precision data-processing instructions and data types. STM32H742xI/G and
STM32H743xI/G devices support a full set of DSP instructions and a memory protection unit
(MPU) to enhance application security.

Description
STM32H742xI/G STM32H743xI/G
STM32H742xI/G and STM32H743xI/G devices operate in the –40 to +85 °C temperature
range from a 1.62 to 3.6 V power supply. The supply voltage can drop down to 1.62 V by
using an external power supervisor (see Section 3.5.2: Power supply supervisor) and
connecting the PDR_ON pin to VSS. Otherwise the supply voltage must stay above 1.71 V
with the embedded power voltage detector enabled.
Dedicated supply inputs for USB (OTG_FS and OTG_HS) are available on all packages
except LQFP100 to allow a greater power supply choice.
A comprehensive set of power-saving modes allows the design of low-power applications.
STM32H742xI/G and STM32H743xI/G devices are offered in 8 packages ranging from 100
pins to 240 pins/balls. The set of included peripherals changes with the device chosen.
These features make STM32H742xI/G and STM32H743xI/G microcontrollers 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
•
Mobile applications, Internet of Things
•
Wearable devices: smart watches.

2.
The SPI1, SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the I2S audio mode.
3.
The maximum CPU frequency of 480 MHz can be obtained on devices revision V.
4.
The product junction temperature must be kept within the –40 to +105 °C temperature range.
5.
Since the LQFP100 package does not feature the PDR_ON pin (tied internally to VDD), the minimum VDD value for this package is 1.71 V.
6.
VDD/VDDA can drop down to 1.62 V by using an external power supervisor (see Section 3.5.2: Power supply supervisor) and connecting PDR_ON pin to VSS. Otherwise the supply voltage must stay
above 1.71 V with the embedded power voltage detector enabled.
7.
The product junction temperature must be kept within the –40 to +125 °C temperature range.

3.1
Arm® Cortex®-M7 with FPU
The Arm® Cortex®-M7 with double-precision FPU 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 optimized power
consumption, while delivering outstanding computational performance and low interrupt
latency.
The Cortex®-M7 processor is a highly efficient high-performance featuring:
•
Six-stage dual-issue pipeline
•
Dynamic branch prediction
•
Harvard architecture with L1 caches (16 Kbytes of I-cache and 16 Kbytes of D-cache)
•
64-bit AXI interface
•
64-bit ITCM interface
•
2x32-bit DTCM interfaces
The following memory interfaces are supported:
•
Separate Instruction and Data buses (Harvard Architecture) to optimize CPU latency
•
Tightly Coupled Memory (TCM) interface designed for fast and deterministic SRAM
accesses
•
AXI Bus interface to optimize Burst transfers
•
Dedicated low-latency AHB-Lite peripheral bus (AHBP) to connect to peripherals.
The processor supports a set of DSP instructions which allow efficient signal processing and
complex algorithm execution.
It also supports single and double precision FPU (floating point unit) speeds up software
development by using metalanguage development tools, while avoiding saturation.
Figure 1 and Figure 2 shows the general block diagram of the STM32H742xI/G and
STM32H743xI/G family.
Note:
Cortex®-M7 with FPU core is binary compatible with the Cortex®-M4 core.
3.2
Memory protection unit (MPU)
The memory protection unit (MPU) manages the CPU access rights and the attributes of the
system resources. It has to be programmed and enabled before use. Its main purposes are
to prevent an untrusted user program to accidentally corrupt data used by the OS and/or by
a privileged task, but also to protect data processes or read-protect memory regions.
The MPU defines access rules for privileged accesses and user program accesses. It
allows defining up to 16 protected regions that can in turn be divided into up to 8
independent subregions, where region address, size, and attributes can be configured. The
protection area ranges from 32 bytes to 4 Gbytes of addressable memory.
When an unauthorized access is performed, a memory management exception is
generated.

Memories
3.3.1
Embedded Flash memory
The STM32H742xI/G and STM32H743xI/G devices embed up to 2 Mbytes of Flash memory
that can be used for storing programs and data.
The Flash memory is organized as 266-bit Flash words memory that can be used for storing
both code and data constants. Each word consists of:
•
One Flash word (8 words, 32 bytes or 256 bits)
•
10 ECC bits.
The Flash memory is divided into two independent banks. Each bank is organized as
follows:
3.3.2
•
A user Flash memory block of 512 Kbytes (STM32H7xxxG) or 1-Mbyte (STM32H7xxxI)
containing eight user sectors of 128 Kbytes (4 K Flash memory words)
•
128 Kbytes of System Flash memory from which the device can boot
•
2 Kbytes (64 Flash words) of user option bytes for user configuration
Embedded SRAM
All devices feature:
•
384 (STM32H742xI/G) or 512 Kbytes (STM32H743xI/G) of AXI-SRAM mapped onto
AXI bus on D1 domain.
•
SRAM1 mapped on D2 domain: 32 (STM32H742xI/G) or 128 Kbytes
(STM32H743xI/G)
•
SRAM2 mapped on D2 domain: 16 (STM32H742xI/G) or 128 Kbytes
(STM32H743xI/G)128 Kbytes
•
SRAM3 mapped on D2 domain: 32 Kbytes (STM32H743xI/G only)
•
SRAM4 mapped on D3 domain: 64 Kbytes
•
4 Kbytes of backup SRAM
The content of this area is protected against possible unwanted write accesses,
and is retained in Standby or VBAT mode.
•
RAM mapped to TCM interface (ITCM and DTCM):
Both ITCM and DTCM RAMs are 0 wait state memories. either They can be accessed
either from the CPU or the MDMA (even in Sleep mode) through a specific AHB slave
of the CPU(AHBP):
–
64 Kbytes of ITCM-RAM (instruction RAM)
This RAM is connected to ITCM 64-bit interface designed for execution of critical
real-times routines by the CPU.
–
128 Kbytes of DTCM-RAM (2x 64-Kbyte DTCM-RAMs on 2x32-bit DTCM ports)
The DTCM-RAM could be used for critical real-time data, such as interrupt service
routines or stack/heap memory. Both DTCM-RAMs can be used in parallel (for
load/store operations) thanks to the Cortex®-M7 dual issue capability.
The MDMA can be used to load code or data in ITCM or DTCM RAMs.

Functional overview
Error code correction (ECC)
Over the product lifetime, and/or due to external events such as radiations, invalid bits in
memories may occur. They can be detected and corrected by ECC. This is an expected
behavior that has to be managed at final-application software level in order to ensure data
integrity through ECC algorithms implementation.
SRAM data are protected by ECC:
•
7 ECC bits are added per 32-bit word.
•
8 ECC bits are added per 64-bit word for AXI-SRAM and ITCM-RAM.
The ECC mechanism is based on the SECDED algorithm. It supports single-error correction
and double-error detection.
3.4
Boot modes
At startup, the boot memory space is selected by the BOOT pin and BOOT_ADDx option
bytes, allowing to program any boot memory address from 0x0000 0000 to 0x3FFF FFFF
which includes:
•
All Flash address space
•
All RAM address space: ITCM, DTCM RAMs and SRAMs
•
The System memory bootloader
The boot loader is located in non-user System memory. It is used to reprogram the Flash
memory through a serial interface (USART, I2C, SPI, USB-DFU). Refer to STM32
microcontroller System memory Boot mode application note (AN2606) for details.
3.5
Power supply management
3.5.1
Power supply scheme
STM32H742xI/G STM32H743xI/G power supply voltages are the following:
•
VDD = 1.62 to 3.6 V: external power supply for I/Os, provided externally through VDD
pins.
•
VDDLDO = 1.62 to 3.6 V: supply voltage for the internal regulator supplying VCORE
•
VDDA = 1.62 to 3.6 V: external analog power supplies for ADC, DAC, COMP and
OPAMP.
•
VDD33USB and VDD50USB:
VDD50USB can be supplied through the USB cable to generate the VDD33USB via the
USB internal regulator. This allows supporting a VDD supply different from 3.3 V.
The USB regulator can be bypassed to supply directly VDD33USB if VDD = 3.3 V.
•
VBAT = 1.2 to 3.6 V: power supply for the VSW domain when VDD is not present.
•
VCAP: VCORE supply voltage, which values depend on voltage scaling (1.0 V, 1.1 V,
1.2 V or 1.35 V). They are configured through VOS bits in PWR_D3CR register and

Functional overview
STM32H742xI/G STM32H743xI/G
ODEN bit in the SYSCFG_PWRCR register. The VCORE domain is split into the
following power domains that can be independently switch off.
–
D1 domain containing some peripherals and the Cortex®-M7 core.
–
D2 domain containing a large part of the peripherals.
–
D3 domain containing some peripherals and the system control.
During power-up and power-down phases, the following power sequence requirements
must be respected (see Figure 3):
•
When VDD is below 1 V, other power supplies (VDDA, VDD33USB, VDD50USB) must
remain below VDD + 300 mV.
•
When VDD is above 1 V, all power supplies are independent.
During the power-down phase, VDD can temporarily become lower than other supplies only
if the energy provided to the microcontroller remains below 1 mJ. This allows external
decoupling capacitors to be discharged with different time constants during the power-down
transient phase.

3.5.2
Functional overview
Power supply supervisor
The devices have an integrated power-on reset (POR)/ power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry:
•
Power-on reset (POR)
The POR supervisor monitors VDD power supply and compares it to a fixed threshold.
The devices remain in Reset mode when VDD is below this threshold,
•
Power-down reset (PDR)
The PDR supervisor monitors VDD power supply. A reset is generated when VDD drops
below a fixed threshold.
The PDR supervisor can be enabled/disabled through PDR_ON pin.
•
Brownout reset (BOR)
The BOR supervisor monitors VDD power supply. Three BOR thresholds (from 2.1 to
2.7 V) can be configured through option bytes. A reset is generated when VDD drops
below this threshold.
3.5.3
Voltage regulator
The same voltage regulator supplies the 3 power domains (D1, D2 and D3). D1 and D2 can
be independently switched off.
Voltage regulator output can be adjusted according to application needs through 6 power
supply levels:
•
•
Run mode (VOS0 to VOS3)
–
Scale 0: boosted performance (available only with LDO regulator)
–
Scale 1: high performance
–
Scale 2: medium performance and consumption
–
Scale 3: optimized performance and low-power consumption
Stop mode (SVOS3 to SVOS5)
–
Scale 3: peripheral with wakeup from Stop mode capabilities (UART, SPI, I2C,
LPTIM) are operational
–
Scale 4 and 5 where the peripheral with wakeup from Stop mode is disabled
The peripheral functionality is disabled but wakeup from Stop mode is possible
through GPIO or asynchronous interrupt.

STM32H742xI/G STM32H743xI/G
Low-power strategy
There are several ways to reduce power consumption on STM32H742xI/G and
STM32H743xI/G:
•
Decrease the dynamic power consumption by slowing down the system clocks even in
Run mode and by individually clock gating the peripherals that are not used.
•
Save power consumption when the CPU is idle, by selecting among the available lowpower mode according to the user application needs. This allows achieving the best
compromise between short startup time, low-power consumption, as well as available
wakeup sources.
The devices feature several low-power modes:
•
CSleep (CPU clock stopped)
•
CStop (CPU sub-system clock stopped)
•
DStop (Domain bus matrix clock stopped)
•
Stop (System clock stopped)
•
DStandby (Domain powered down)
•
Standby (System powered down)
CSleep and CStop low-power modes are entered by the MCU when executing the WFI
(Wait for Interrupt) or WFE (Wait for Event) instructions, or when the SLEEPONEXIT bit of
the Cortex®-Mx core is set after returning from an interrupt service routine.
A domain can enter low-power mode (DStop or DStandby) when the processor, its
subsystem and the peripherals allocated in the domain enter low-power mode.
If part of the domain is not in low-power mode, the domain remains in the current mode.
Finally the system can enter Stop or Standby when all EXTI wakeup sources are cleared
and the power domains are in DStop or DStandby mode.

Functional overview
Reset and clock controller (RCC)
The clock and reset controller is located in D3 domain. The RCC manages the generation of
all the clocks, as well as the clock gating and the control of the system and peripheral
resets. It provides a high flexibility in the choice of clock sources and allows to apply clock
ratios to improve the power consumption. In addition, on some communication peripherals
that are capable to work with two different clock domains (either a bus interface clock or a
kernel peripheral clock), the system frequency can be changed without modifying the
baudrate.
3.7.1
Clock management
The devices embed four internal oscillators, two oscillators with external crystal or
resonator, two internal oscillators with fast startup time and three PLLs.
The RCC receives the following clock source inputs:
•
Internal oscillators:
–
•
64 MHz HSI clock
–
48 MHz RC oscillator
–
4 MHz CSI clock
–
32 kHz LSI clock
External oscillators:
–
HSE clock: 4-50 MHz (generated from an external source) or 4-48 MHz(generated
from a crystal/ceramic resonator)
–
LSE clock: 32.768 kHz
The RCC provides three PLLs: one for system clock, two for kernel clocks.
The system starts on the HSI clock. The user application can then select the clock
configuration.
3.7.2
System reset sources
Power-on reset initializes all registers while system reset reinitializes the system except for
the debug, part of the RCC and power controller status registers, as well as the backup
power domain.
A system reset is generated in the following cases:
•
Power-on reset (pwr_por_rst)
•
Brownout reset
•
Low level on NRST pin (external reset)
•
Window watchdog
•
Independent watchdog
•
Software reset
•
Low-power mode security reset
•

STM32H742xI/G STM32H743xI/G
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.
After reset, all GPIOs (except debug pins) are in Analog mode to reduce power
consumption (refer to GPIOs register reset values in the device reference manual).
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.
3.9
Bus-interconnect matrix
The devices feature an AXI bus matrix, two AHB bus matrices and bus bridges that allow
interconnecting bus masters with bus slaves (see Figure 4).
Figure 4 shows STM32H743xI/G bus matrix. All peripherals may not be available for
STM32H742xI/G (refer to Table 2: STM32H742xI/G and STM32H743xI/G features and
peripheral counts).

DMA controllers
The devices feature four DMA instances to unload CPU activity:
•
A master direct memory access (MDMA)
The MDMA is a high-speed DMA controller, which is in charge of all types of memory
transfers (peripheral to memory, memory to memory, memory to peripheral), without
any CPU action. It features a master AXI interface and a dedicated AHB interface to
access Cortex®-M7 TCM memories.
The MDMA is located in D1 domain. It is able to interface with the other DMA
controllers located in D2 domain to extend the standard DMA capabilities, or can
manage peripheral DMA requests directly.
Each of the 16 channels can perform single block transfers, repeated block transfers
and linked list transfers.
•
Two dual-port DMAs (DMA1, DMA2) located in D2 domain, with FIFO and request
router capabilities.
•
One basic DMA (BDMA) located in D3 domain, with request router capabilities.
The DMA request router could be considered as an extension of the DMA controller. It
routes the DMA peripheral requests to the DMA controller itself. This allowing managing the
DMA requests with a high flexibility, maximizing the number of DMA requests that run
concurrently, as well as generating DMA requests from peripheral output trigger or DMA
event.
3.11
Chrom-ART Accelerator (DMA2D)
The Chrom-Art Accelerator (DMA2D) is a graphical accelerator which offers advanced bit
blitting, row data copy and pixel format conversion. It supports the following functions:
•
Rectangle filling with a fixed color
•
Rectangle copy
•
Rectangle copy with pixel format conversion
•
Rectangle composition with blending and pixel format conversion
Various image format coding are supported, from indirect 4bpp color mode up to 32bpp
direct color. It embeds dedicated memory to store color lookup tables. The DMA2D also
supports block based YCbCr to handle JPEG decoder output.
An interrupt can be generated when an operation is complete or at a programmed
watermark.
All the operations are fully automatized and are running independently from the CPU or the
DMAs.

•
Allows early processing of interrupts
•
Processing of late arriving, higher-priority interrupts
•
Support tail chaining
•
Processor context automatically saved on interrupt entry, and restored on interrupt exit
with no instruction overhead

latency.
3.13
Extended interrupt and event controller (EXTI)
The EXTI controller performs interrupt and event management. In addition, it can wake up
the processor, power domains and/or D3 domain from Stop mode.
The EXTI handles up to 89 independent event/interrupt lines split as 28 configurable events
and 61 direct events .
Configurable events have dedicated pending flags, active edge selection, and software
trigger capable.
Direct events provide interrupts or events from peripherals having a status flag.
3.14
Cyclic redundancy check calculation unit (CRC)
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code using a
programmable 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.

3.16
–
Static random access memory (SRAM)
–
NOR Flash memory/OneNAND Flash memory
–
PSRAM (4 memory banks)
–

Quad-SPI memory interface (QUADSPI)
All devices embed a Quad-SPI memory interface, which is a specialized communication
interface targeting Single, Dual or Quad-SPI Flash memories. It supports both single and
double datarate operations.
It can operate in any of the following modes:
•
Direct mode through registers
•
External Flash status register polling mode
•
Memory mapped mode.
Up to 256 Mbytes of external Flash memory can be mapped, and 8-, 16- and 32-bit data
accesses are supported as well as code execution.

The STM32H742xI/G and STM32H743xI/G devices embed three analog-to-digital
converters, which resolution can be configured to 16, 14, 12, 10 or 8 bits.
Each ADC shares up to 20 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, thus allowing to automatically transfer ADC
converted values to a destination location without any software action.

STM32H742xI/G STM32H743xI/G
Functional overview
In addition, an analog watchdog feature can accurately monitor 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, TIM6, TIM8, TIM15, HRTIM1 and LPTIM1 timer.
3.18
Temperature sensor
STM32H742xI/G and STM32H743xI/G devices embed a temperature sensor that generates
a voltage (VTS) that varies linearly with the temperature. This temperature sensor is
internally connected to ADC3_IN18. The conversion range is between 1.7 V and 3.6 V. It
can measure the device junction temperature ranging from − 40 up to +125 °C.
The temperature sensor have a good linearity, but it has to be calibrated to obtain a good
overall accuracy of the temperature measurement. As the temperature sensor offset 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, which is accessible in Read-only mode.
3.19
VBAT operation
The VBAT power domain contains the RTC, the backup registers and the backup SRAM.
To optimize battery duration, this power domain is supplied by VDD when available or by the
voltage applied on VBAT pin (when VDD supply is not present). VBAT power is switched
when the PDR detects that VDD dropped below the PDR level.
The voltage on the VBAT pin could be provided by an external battery, a supercapacitor or
directly by VDD, in which case, the VBAT mode is not functional.
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 connected to VSS (Internal Reset OFF), the VBAT functionality is no
more available and VBAT pin should be connected to VDD.

High-resolution timer (HRTIM1)
The high-resolution timer (HRTIM1) allows generating digital signals with high-accuracy
timings, such as PWM or phase-shifted pulses.
It consists of 6 timers, 1 master and 5 slaves, totaling 10 high-resolution outputs, which can
be coupled by pairs for deadtime insertion. It also features 5 fault inputs for protection
purposes and 10 inputs to handle external events such as current limitation, zero voltage or
zero current switching.
The HRTIM1 timer is made of a digital kernel clocked at 480 MHz The high-resolution is
available on the 10 outputs in all operating modes: variable duty cycle, variable frequency,
and constant ON time.
The slave timers can be combined to control multiswitch complex converters or operate
independently to manage multiple independent converters.
The waveforms are defined by a combination of user-defined timings and external events
such as analog or digital feedbacks signals.
HRTIM1 timer includes options for blanking and filtering out spurious events or faults. It also
offers specific modes and features to offload the CPU: DMA requests, Burst mode
controller, Push-pull and Resonant mode.
It supports many topologies including LLC, Full bridge phase shifted, buck or boost
converters, either in voltage or current mode, as well as lighting application (fluorescent or
LED). It can also be used as a general purpose timer, for instance to achieve high-resolution
PWM-emulated DAC.

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:
•

•
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 (0100%).
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.
3.28.3
General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32H742xI/G
and STM32H743xI/G devices (see Table 5 for differences).

TIM2, TIM3, TIM4, TIM5
The devices include 4 full-featured general-purpose timers: TIM2, TIM3, TIM4 and
TIM5. TIM2 and TIM5 are based on a 32-bit auto-reload up/downcounter and a 16-bit
prescaler while TIM3 and TIM4 are based on a 16-bit auto-reload up/downcounter and
a 16-bit prescaler. All timers 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.
TIM2, TIM3, TIM4 and 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.

These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM13, TIM14, TIM16 and TIM17 feature one independent channel, whereas TIM12
and TIM15 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 or used as simple timebases.

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.
3.28.7
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It

Real-time clock (RTC), backup SRAM and backup registers
The RTC is an independent BCD timer/counter. It supports the following features:
•
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format.
•
Automatic correction for 28, 29 (leap year), 30, and 31 days of the month.
•
Two programmable alarms.
•
On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to
synchronize it with a master clock.
•
Reference clock detection: a more precise second source clock (50 or 60 Hz) can be
used to enhance the calendar precision.
•
Digital calibration circuit with 0.95 ppm resolution, to compensate for quartz crystal
inaccuracy.
•
Three anti-tamper detection pins with programmable filter.
•
Timestamp feature which can be used to save the calendar content. This function can
be triggered by an event on the timestamp pin, or by a tamper event, or by a switch to
VBAT mode.
•
17-bit auto-reload wakeup timer (WUT) for periodic events with programmable
resolution and period.
The RTC and the 32 backup registers are supplied through a switch that takes power either
from the VDD supply when present or from the VBAT pin.
The backup registers are 32-bit registers used to store 128 bytes of user application data
when VDD power is not present. They are not reset by a system or power reset, or when the
device wakes up from Standby mode.
The RTC clock sources can be:
•
A 32.768 kHz external crystal (LSE)
•
An external resonator or oscillator (LSE)
•
The internal low-power RC oscillator (LSI, with typical frequency of 32 kHz)
•
The high-speed external clock (HSE) divided by 32.
The RTC is functional in VBAT mode and in all low-power modes when it is clocked by the
LSE. When clocked by the LSI, the RTC is not functional in VBAT mode, but is functional in
all low-power modes.
All RTC events (Alarm, Wakeup Timer, Timestamp or Tamper) can generate an interrupt and
wakeup the device from the low-power modes.

receiver transmitters (USART1, USART2, USART3 and USART6) and four universal
asynchronous receiver transmitters (UART4, UART5, UART7 and UART8). Refer to Table 6
for a summary of USARTx and UARTx features.
These interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire Half-duplex communication mode and
have LIN Master/Slave capability. They provide hardware management of the CTS and RTS
signals, and RS485 Driver Enable. They are able to communicate at speeds of up to
12.5 Mbit/s.
USART1, USART2, USART3 and USART6 also provide Smartcard mode (ISO 7816
compliant) and SPI-like communication capability.
The USARTs embed a Transmit FIFO (TXFIFO) and a Receive FIFO (RXFIFO). FIFO mode
is enabled by software and is disabled by default.

Low-power universal asynchronous receiver transmitter
(LPUART)
The device embeds one Low-Power UART (LPUART1). The LPUART supports
asynchronous serial communication with minimum power consumption. It supports half
duplex single wire communication and modem operations (CTS/RTS). It allows
multiprocessor communication.
The LPUARTs embed a Transmit FIFO (TXFIFO) and a Receive FIFO (RXFIFO). FIFO
mode is enabled by software and is disabled by default.

STM32H742xI/G STM32H743xI/G
Functional overview
The LPUART has a clock domain independent from the CPU clock, and can wakeup the
system from Stop mode. The wakeup from Stop mode are programmable and can be done
on:
•
Start bit detection
•
Any received data frame
•
A specific programmed data frame
•
Specific TXFIFO/RXFIFO status when FIFO mode is enabled.
Only a 32.768 kHz clock (LSE) is needed to allow LPUART communication up to
9600 baud. Therefore, even in Stop mode, the LPUART can wait for an incoming frame
while having an extremely low energy consumption. Higher speed clock can be used to
reach higher baudrates.
LPUART interface can be served by the DMA controller.
3.33
Serial peripheral interfaces (SPI)/integrated interchip
sound interfaces (I2S)
The devices feature up to six SPIs (SPI2S1, SPI2S2, SPI2S3, SPI4, SPI5 and SPI6) that
allow communicating up to 150 Mbits/s in Master and Slave modes, in Half-duplex, Fullduplex and Simplex modes. The 3-bit prescaler gives 8 master mode frequencies and the
frame is configurable from 4 to 16 bits. All SPI interfaces support NSS pulse mode, TI mode,
Hardware CRC calculation and 8x 8-bit embedded Rx and Tx FIFOs with DMA capability.
Three standard I2S interfaces (multiplexed with SPI1, SPI2 and SPI3) are available. They
can be operated in Master or Slave mode, in Simplex or Full-duplex communication mode,
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 I2S interfaces support 16x 8bit embedded Rx and Tx FIFOs with DMA capability.
3.34
Serial audio interfaces (SAI)
The devices embed 4 SAIs (SAI1, SAI2, SAI3 and SAI4) that allow designing many stereo
or mono audio protocols such as I2S, LSB or MSB-justified, PCM/DSP, TDM or AC’97. An
SPDIF output is available when the audio block is configured as a transmitter. To bring this
level of flexibility and reconfigurability, the SAI contains two independent audio sub-blocks.
Each block has it own clock generator and I/O line controller.
Audio sampling frequencies up to 192 kHz are supported.
In addition, up to 6 microphones can be supported thanks to an embedded PDM interface.
The SAI can work in master or slave configuration. The audio sub-blocks can be either
receiver or transmitter and can work synchronously or asynchronously (with respect to the
other one). The SAI can be connected with other SAIs to work synchronously.

SPDIFRX Receiver Interface (SPDIFRX)
The SPDIFRX peripheral is designed to receive an S/PDIF flow compliant with IEC-60958
and IEC-61937. These standards support simple stereo streams up to high sample rate,
and compressed multi-channel surround sound, such as those defined by Dolby or DTS (up
to 5.1).
The main SPDIFRX features are the following:
•
Up to 4 inputs available
•
Automatic symbol rate detection
•
Maximum symbol rate: 12.288 MHz
•
Stereo stream from 32 to 192 kHz supported
•
Supports Audio IEC-60958 and IEC-61937, consumer applications
•
Parity bit management
•

•
Interrupt capabilities
The SPDIFRX receiver provides all the necessary features to detect the symbol rate, and
decode the incoming data stream. The user can select the wanted SPDIF input, and when a
valid signal will be available, the SPDIFRX will re-sample the incoming signal, decode the
Manchester stream, recognize frames, sub-frames and blocks elements. It delivers to the
CPU decoded data, and associated status flags.
The SPDIFRX also offers a signal named spdif_frame_sync, which toggles at the S/PDIF
sub-frame rate that will be used to compute the exact sample rate for clock drift algorithms.
3.36

Two SDMMC host interfaces are available. They support MultiMediaCard System
Specification Version 4.51 in three different databus modes: 1 bit (default), 4 bits and 8 bits.
Both interfaces support the SD memory card specifications version 4.1. and the SDIO card
specification version 4.0. in two different databus modes: 1 bit (default) and 4 bits.
Each SDMMC host interface supports only one SD/SDIO/MMC card at any one time and a
stack of MMC Version 4.51 or previous.
The SDMMC host interface embeds a dedicated DMA controller allowing high-speed
transfers between the interface and the SRAM.
3.39
Controller area network (FDCAN1, FDCAN2)
The controller area network (CAN) subsystem consists of two CAN modules, a shared
message RAM memory and a clock calibration unit.
Both CAN modules (FDCAN1 and FDCAN2) are compliant with ISO 11898-1 (CAN protocol
specification version 2.0 part A, B) and CAN FD protocol specification version 1.0.
FDCAN1 supports time triggered CAN (TT-FDCAN) specified in ISO 11898-4, including
event synchronized time-triggered communication, global system time, and clock drift
compensation. The FDCAN1 contains additional registers, specific to the time triggered
feature. The CAN FD option can be used together with event-triggered and time-triggered
CAN communication.
A 10-Kbyte message RAM memory implements filters, receive FIFOs, receive buffers,
transmit event FIFOs, transmit buffers (and triggers for TT-FDCAN). This message RAM is
shared between the two FDCAN1 and FDCAN2 modules.
The common clock calibration unit is optional. It can be used to generate a calibrated clock
for both FDCAN1 and FDCAN2 from the HSI internal RC oscillator and the PLL, by
evaluating CAN messages received by the FDCAN1.

1. When this pin/ball was previously configured as an oscillator, the oscillator function is kept during and after a reset. This is
valid for all resets except for power-on reset.
2. This ball should remain floating.
3. This ball should not remain floating. It can be connected to VSS or VDD. It is reserved for future use.
4. This ball should be connected to VSS.
5. Pxy_C and Pxy pins/balls are two separate pads (analog switch open). The analog switch is configured through a SYSCFG
register. Refer to the product reference manual for a detailed description of the switch configuration bits.
6. There is a direct path between Pxy_C and Pxy pins/balls, through an analog switch. Pxy alternate functions are available on
Pxy_C when the analog switch is closed. The analog switch is configured through a SYSCFG register. Refer to the product
reference manual for a detailed description of the switch configuration bits.
7. VREF+ pin, and consequently the internal voltage reference, are not available on the TFBGA100 package. On this package,
this pin is double-bonded to VDDA which can be connected to an external reference. The internal voltage reference buffer is
not available and must be kept disabled
8. When it is not available on a package, the VDDLDO pin is internally tied to VDD.
9. When the pin is used in USB configuration (OTG_HS_ID/OTG_HS_VBUS), the I/O is supplied by VDD33USB, otherwise it is
supplied by VDD.
10. When it is not available on a package, the VDD50USB pin is internally tied to VDD33USB.

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 junction temperature, supply voltage and frequencies by tests in production on
100% of the devices with an junction temperature at TJ = 25 °C and TJ = TJmax (given by the
selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes. 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).
6.1.2
Typical values
Unless otherwise specified, typical data are based on TJ = 25 °C, VDD = 3.3 V (for the
1.7 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).
6.1.3
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.

Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 13.

1. N corresponds to the number of VDD pins available on the package.
2. A tolerance of +/- 20% is acceptable on decoupling capacitors.
Caution:
Each power supply pair (VDD/VSS, VDDA/VSSA ...) 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 good operation of the

Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 21: Voltage characteristics,
Table 22: Current characteristics, and Table 23: Thermal characteristics may cause
permanent damage to the device. These are stress ratings only and the functional operation
of the device at these conditions is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability. Device mission profile (application conditions)
is compliant with JEDEC JESD47 Qualification Standard, extended mission profiles are
available on demand.

1. All main power (VDD, VDDA, VDD33USB) and ground (VSS, VSSA) pins must always be connected to the
external power supplies, in the permitted range.
2. This current consumption must be correctly distributed over all I/Os and control pins. The total output
current must not be sunk/sourced between two consecutive power supply pins referring to high pin count
QFP packages.
3. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the
specified maximum value.
4. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN
