Description
Description
STM32H735xG devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC
core operating at up to 550 MHz. The Cortex® -M7 core features a floating point unit (FPU)
which supports Arm® double-precision (IEEE 754 compliant) and single-precision dataprocessing instructions and data types. The Cortex -M7 core includes 32 Kbytes of
instruction cache and 32 Kbytes of data cache. STM32H735xG devices support a full set of
DSP instructions and a memory protection unit (MPU) to enhance application security.
STM32H735xG devices incorporate high-speed embedded memories with 1 Mbyte of Flash
memory, up to 564 Kbytes of RAM (including 192 Kbytes that can be shared between ITCM
and AXI, plus 64 Kbytes exclusively ITCM, plus 128 Kbytes exclusively AXI, 128 Kbyte
DTCM, 48 Kbytes AHB and 4 Kbytes of backup RAM), as well as an extensive range of
enhanced I/Os and peripherals connected to APB buses, AHB buses, 2x32-bit multi-AHB
bus matrix and a multi layer AXI interconnect supporting internal and external memory
access. To improve application robustness, all memories feature error code correction (one
error correction, two error detections).
The devices embed peripherals allowing mathematical/arithmetic function acceleration
(CORDIC coprocessor for trigonometric functions and FMAC unit for filter functions). All the
devices offer three ADCs, two DACs, two operational amplifiers, two ultra-low power
comparators, a low-power RTC, 4 general-purpose 32-bit timers, 12 general-purpose 16-bit
timers including two PWM timers for motor control, five low-power timers, a true random
number generator (RNG), and a cryptographic acceleration cell, and a HASH processor.
The devices support four digital filters for external sigma-delta modulators (DFSDM). They
also feature standard and advanced communication interfaces.

STM32H735xG
•
Advanced peripherals including
–
A flexible memory control (FMC) interface
–
Two Octo-SPI memory interfaces with on-the-fly decryption (OTFDEC)
–
A camera interface for CMOS sensors
–
An LCD-TFT display controller
Refer to Table 2: STM32H735xG features and peripheral counts for the list of peripherals
available on each part number.
To reduce the power consumption the STM32H735xG include an optional step-down
converter that can be used either for internal or external supply, or both.
STM32H735xG devices operate in the –40 to +125 °C ambient 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 3.8.2: 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 are available to allow a greater power supply choice.
A comprehensive set of power-saving modes allows the design of low-power applications.
STM32H735xG devices are offered in several packages ranging from 68 to 176 pins/balls.
The set of included peripherals changes with the device chosen.
These features make STM32H735xG 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
•

Functional overview
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 (32 Kbytes of I-cache and 32 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 shows the general block diagram of the STM32H735xG family.
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 STM32H735xG devices embed 1 Mbyte 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 (single-error correction and double-error detection).
The Flash memory is organized as follows:
3.3.2
•
1 Mbyte of user Flash memory block 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:
•
from 128 to 320 Kbytes of AXI-SRAM mapped onto the AXI bus on D1 domain
•
SRAM1 mapped on D2 domain: 16 Kbytes
•
SRAM2 mapped on D2 domain: 16 Kbytes
•
SRAM4 mapped on D3 domain: 16 Kbytes
•
4 Kbytes of backup SRAM
The content of this area is protected against possible unwanted write accesses, and
can be retained in Standby or VBAT mode.
•
RAM mapped to TCM interface (ITCM and DTCM):
Both ITCM and DTCM RAMs are 0 wait state memories. They can be accessed either
from the CPU or the MDMA (even in Sleep mode) through a specific AHB slave of the
Cortex®-M7CPU(AHBSAHBP):
–
64 to 256 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. As reflected
above, 192 Kbyte of RAM can be used either for AXI SRAM or ITCM, with a 64Kbyte
granularity.

STM32H735xG
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
Secure access mode
In addition to other typical memory protection mechanism (RDP, PCROP), STM32H735xG
devices introduce the Secure access mode, a new enhanced security feature. This mode
allows developing user-defined secure services by ensuring, on the one hand code and
data protection and on the other hand code safe execution.
Two types of secure services are available:
•
STMicroelectronics Root Secure Services:
These services are embedded in System memory. They provide a secure solution for
firmware and third-party modules installation. These services rely on cryptographic
algorithms based on a device unique private key.
•
User-defined secure services:
These services are embedded in user Flash memory. Examples of user secure
services are proprietary user firmware update solution, secure Flash integrity check or
any other sensitive applications that require a high level of protection.
The secure firmware is embedded in specific user Flash memory areas configured
through option bytes.
Secure services are executed just after a reset and preempt all other applications to
guarantee protected and safe execution. Once executed, the corresponding code and data
are no more accessible.
The above secure services is activated for the next reset exits through an option bit.

bytes, allowing to program any boot memory address from 0x0000 0000 to 0x3FFF FFFF
which includes:
•
All Flash address space

CORDIC co-processor (CORDIC)
The CORDIC co-processor provides hardware acceleration of certain mathematical
functions, notably trigonometric, commonly used in motor control, metering, signal
processing and many other applications.
It speeds up the calculation of these functions compared to a software implementation,
allowing a lower operating frequency, or freeing up processor cycles in order to perform
other tasks.
The filter mathematical accelerator unit performs arithmetic operations on vectors. It
comprises a multiplier/accumulator (MAC) unit, together with address generation logic,
which allows it to index vector elements held in local memory.
The unit includes support for circular buffers on input and output, which allows digital filters
to be implemented. Both finite and infinite impulse response filters can be realized.
The unit allows frequent or lengthy filtering operations to be offloaded from the CPU, freeing
up the processor for other tasks. In many cases it can accelerate such calculations
compared to a software implementation, resulting in a speed-up of time critical tasks.

Power supply management
3.8.1
Power supply scheme
STM32H735xG 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: allows the support of a VDD supply different from 3.3 V while powering the
USB transceiver with 3.3V on VDD33USB.
•
VDD50USB can be supplied through the USB cable to generate the VDD33USB via the
USB internal regulator. This allows support of a VDD supply different to 3.3 V.
The USB regulator can be bypassed to supply directly VDD33USB if VDD = 3.3 V.
26/284
•
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. The
DS13312 Rev 3
STM32H735xG
Functional overview
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
•
VDDSMPS= 1.62 V to 3.6 V: SMPS step-down converter power supply VDDSMPS
must be kept at the same voltage level as VDD
•
VLXSMPS = SMPS step-down converter output coupled to an inductor
•
VFBSMPS = VCORE or 1.8 V or 2.5 V external SMPS step-down converter feedback
voltage sense input.
During power-up and power-down phases, the following power sequence requirements
must be respected (see Figure 2):
•
When VDD is below VDDmin, other power supplies (VDDA, VDD33USB, VDD50USB) must
remain below VDD + 300 mV.
•
When VDD is above VDDmin, 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.

STM32H735xG
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.

be independently switched off.
Voltage regulator output can be adjusted according to application needs through 6 power
supply levels:
•
•
3.9
Run mode (VOS0 to VOS3)
–
Scale 0: boosted performance
–
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.
Low-power strategy
There are several ways to reduce power consumption on STM32H735xG:
•
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 when the CPU is idle, by selecting among the available low-power modes
according to the user application needs. This allows the best compromise between
short startup time and low power consumption to be achieved, according to the
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.

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), thus the system frequency can be changed without modifying the
baudrate.
3.10.1
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.

Functional overview
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:
3.11
•
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
•
Exit from Standby
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.

Functional overview
DMA controllers
The devices feature four DMA instances and a DMA request router 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.
•
A DMA request multiplexer (DMAMUX)
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.
3.14
Chrom-ART Accelerator (DMA2D)
The Chrom-Art Accelerator (DMA2D) is a specialized DMA dedicated to image manipulation.
It can perform the following operations:
•
Filling a part or the whole of a destination image with a specific color
•
Copying a part or the whole of a source image into a part or the whole of a destination
•
image
•
Copying a part or the whole of a source image into a part or the whole of a destination
•
image with a pixel format conversion
•
Blending a part and/or two complete source images with different pixel format and copy
•
the result into a part or the whole of a destination image with a different color format.
•
All the classical color coding schemes are supported from 4-bit up to 32-bit per pixel
with indexed or direct color mode, including block based YCbCr to handle JPEG
decoder output.
•
The DMA2D has its own dedicated memories for CLUTs (color look-up tables).
An interrupt can be generated when an operation is complete or at a programmed
watermark.
All the operations are fully automated and are running independently from the CPU or the
DMAs.

with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
3.16
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 80 independent event/interrupt lines split as 26 configurable events
and 54 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.
3.17
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.

Read FIFO for SDRAM controller
•
The maximum FMC_CLK/FMC_SDCLK frequency for synchronous accesses is the
FMC kernel clock divided by 2.
Octo-SPI memory interface (OCTOSPI)
The OCTOSPI is a specialized communication interface targeting single, dual, quad or octal
SPI memories. The STM32H735xG embeds two separate Octo-SPI interfaces.
Each OCTOSPI instance supports single/dual/quad/octal SPI formats. multiplexing of
single/dual/quad/octal SPI over the same bus can be achieved using the integrated OctoSPI I/O manager (OCTOSPIM).
The OCTOSPI can operate in any of the three following modes:
•
Indirect mode: all the operations are performed using the OCTOSPI registers
•
Status-polling mode: the external memory status register is periodically read and an
interrupt can be generated in case of flag setting
•
Memory-mapped mode: the external memory is memory mapped and it is seen by the
system as if it was an internal memory supporting both read and write operations.
The OCTOSPI supports two frame formats supported by most external serial memories
such as serial PSRAMs, serial NAND and serial NOR Flash memories, Hyper RAMs and
Hyper Flash memories.
Multi chip package (MCP) combining any of the above mentioned memory types can also
be supported.

STM32H735xG
Analog-to-digital converters (ADCs)
STM32H735xG devices embed three analog-to-digital converters, two of 16-bit resolution,
and the third of 12-bit resolution. The 16-bit resolution ADCs can be configured as 16, 14,
12, 10 or 8 bits. The 12-bit resolution ADC can be configured to 12, 10 or 8 bits.
Each ADC shares up to 20 external channels, performing conversions in 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 automatic transfer of ADC
converted values to a destination location without any software action.
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 can be triggered by any of the TIM1,
TIM2, TIM3, TIM4, TIM6, TIM8, TIM15, TIM23, TIM24, and LPTIM1 timers.
3.21
Temperature sensor
STM32H735xG devices embed a temperature sensor that generates a voltage (VTS) that
varies linearly with the temperature. This temperature sensor is internally connected to
ADC3_IN17. The conversion range is between 1.7 V and 3.6 V. It can measure the device
junction temperature ranging from − 40 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.
3.22
Digital temperature sensor (DTS)
STM32H735xG devices embed a sensor that converts the temperature into a square wave
the frequency of which is proportional to the temperature. The PCLK or the LSE clock can
be used as the reference clock for the measurements. A formula given in the product
reference manual allows calculation of the temperature according to the measured
frequency stored in the DTS_DR register.

Functional overview
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.
3.24
Digital-to-analog converters (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 including DMA underrun error detection
•
external triggers for conversion
•
input voltage reference VREF+ or internal VREFBUF reference.
The DAC channels are triggered through the timer update outputs that are also connected
to different DMA streams.

speed for low-power) as well as selectable output polarity.
The reference voltage can be one of the following:
•
An external I/O

Digital camera interface (DCMI)
The devices 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

PSSI
The PSSI is a generic synchronous 8-/16-bit parallel data input/output slave interface. It
allows the transmitter to send a data valid signal to indicate when the data is valid, and the
receiver to output a flow control signal to indicate when it is ready to sample the data.
The main PSSI features are:

Slave mode operation
•
8- or 16-bit parallel data input or output
•
8-word (32-byte) FIFO

When enabled, these signals can either allow the transmitter to indicate when the data is
valid or, the receiver to indicate when it is ready to sample the data, or both.
The PSSI shares most of its circuitry with the digital camera interface (DCMI). It therefore
cannot be used simultaneously with the DCMI.

3.34.1
STM32H735xG
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 (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.
3.34.2
General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32H735xG
devices (see Table 5: Timer feature comparison for differences).
•
TIM2, TIM3, TIM4, TIM5, TIM23, TIM24
The devices include 4 full-featured general-purpose timers: TIM2, TIM3, TIM4, TIM5,
TIM23 and TIM24. TIM2, TIM5, TIM23 and TIM24 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 24 input capture/output compare/PWMs on the largest packages.
TIM2, TIM3, TIM4, TIM5, TIM23 and TIM24 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, TIM23, and TIM24 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.
•
TIM12, TIM13, TIM14, TIM15, TIM16, TIM17
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,
TIM23, and TIM24 full-featured general-purpose timers or used as simple time bases.

Low-power timers (LPTIM1, LPTIM2, LPTIM3, LPTIM4, LPTIM5)
The low-power timers have an independent clock and is running also in Stop mode if it is
clocked by LSE, LSI or an external clock. It is able to wakeup the devices from Stop mode.
This low-power timer supports the following features:
3.34.5
•
16-bit up counter with 16-bit autoreload register
•
16-bit compare register
•
Configurable output: pulse, PWM
•
Continuous / One-shot mode
•
Selectable software / hardware input trigger
•

•
External clock source over LPTIM input (working even with no internal clock source
running, used by the Pulse Counter Application)
•
Programmable digital glitch filter
•
Encoder mode
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.
A window option allows the device to be reset when a reload operation is made too early
after the previous reload.
3.34.6
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.
3.34.7
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
•

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.

(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.

DS13312 Rev 3
STM32H735xG
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
•

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.
3.39
Serial peripheral interface (SPI)/inter- integrated sound
interfaces (I2S)
The devices feature up to six SPIs (SPI2S1, SPI2S2, SPI2S3, SPI4, SPI5 and SPI2S6) 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.
Four standard I2S interfaces (multiplexed with SPI1, SPI2, SPI3 and SPI6) are available.
They can be operated in Master or Slave mode, in Simplex communication modes, and can
be configured to operate as a 16-/32-bit resolution input or output channel (except SPI2S6
which is limited to 16 bits). 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 8-bit embedded Rx and Tx FIFOs with DMA
capability.
3.40
Serial audio interfaces (SAI)
The devices embed 2 SAIs (SAI1, 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 8 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.

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.

SD/SDIO/MMC card host interfaces (SDMMC)
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.
3.45
Controller area network (FDCAN1, FDCAN2, FDCAN3)
The controller area network (CAN) subsystem consists of two CAN modules, a shared
message RAM memory and a clock calibration unit.
All CAN modules (FDCAN1, FDCAN2, and FDCAN3) 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 three modules - FDCAN1 FDCAN2 and FDCAN3.
The common clock calibration unit is optional. It can be used to generate a calibrated clock
for FDCAN1, FDCAN2 and FDCAN3 from the HSI internal RC oscillator and the PLL, by
evaluating CAN messages received by the FDCAN1.

Universal serial bus on-the-go high-speed (OTG_HS)
The devices embed an USB OTG high-speed (up to 480 Mbit/s) device/host/OTG peripheral
that supports both full-speed and high-speed operations. It integrates the transceivers for
full-speed operation (12 Mbit/s) and a UTMI low-pin interface (ULPI) for high-speed
operation (480 Mbit/s). When using the USB OTG_HS interface 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
2.0 specification. It features software-configurable endpoint setting and supports
suspend/resume. The USB OTG_HS controller requires a dedicated 48 MHz clock that is
generated by a PLL connected to the HSE oscillator.
The main features are:
3.47
•
Combined Rx and Tx FIFO size of 4 Kbytes with dynamic FIFO sizing
•
Supports the session request protocol (SRP) and host negotiation protocol (HNP)
•
8 bidirectional endpoints
•
16 host channels with periodic OUT support
•
Software configurable to OTG1.3 and OTG2.0 modes of operation
•

1. 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.
2. 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.

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 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.
6.1.4
Loading capacitor
The loading conditions used for pin parameter measurement are shown in Figure 12.
6.1.5
Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 13.

Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 10: Voltage characteristics,
Table 11: Current characteristics, and Table 12: 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.

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
