DS12110 Rev 10 17/357 54 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.

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.

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. 26/357 DS12110 Rev 10 STM32H742xI/G STM32H743xI/G 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 with VDD33USB ≈ 3.3 V (see electrical characteristics). • 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 DS12110 Rev 10 27/357 54 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. Figure 3.

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. DS12110 Rev 10 29/357 54 Functional overview 3.6 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. Table 3. System vs domain low-power mode System power mode Run 30/357 D1 domain power mode D2 domain power mode DRun/DStop/DStandby DRun/DStop/DStandby D3 domain power mode DRun Stop DStop/DStandby DStop/DStandby DStop Standby DStandby DStandby DStandby DS12110 Rev 10 STM32H742xI/G STM32H743xI/G 3.7 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 • Exit from Standby DS12110 Rev 10 31/357 54 Functional overview 3.8 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). 32/357 DS12110 Rev 10 STM32H742xI/G STM32H743xI/G Figure 4.

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. 34/357 DS12110 Rev 10 STM32H742xI/G STM32H743xI/G 3.12 Functional overview Nested vectored interrupt controller (NVIC) The devices embed a nested vectored interrupt controller which is able to manage 16 priority levels, and handle up to 150 maskable interrupt channels plus the 16 interrupt lines of the Cortex®-M7 with FPU core. • 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 context automatically saved on interrupt entry, and restored on interrupt exit with no instruction overhead This hardware block provides flexible interrupt management features with minimum interrupt 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. DS12110 Rev 10 35/357 54 Functional overview 3.15 STM32H742xI/G STM32H743xI/G Flexible memory controller (FMC) The FMC controller main features are the following: • Interface with static-memory mapped devices including: 3.16 – Static random access memory (SRAM) – NOR flash memory/OneNAND flash memory – PSRAM (4 memory banks) – NAND flash memory with ECC hardware to check up to 8 Kbytes of data • Interface with synchronous DRAM (SDRAM/Mobile LPSDR SDRAM) memories • 8-,16-,32-bit data bus width • Independent Chip Select control for each memory bank • Independent configuration for each memory bank • Write FIFO • Read FIFO for SDRAM controller • The maximum FMC_CLK/FMC_SDCLK frequency for synchronous accesses is the FMC kernel clock divided by 2. 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 opcode and the frame format are fully programmable. 3.17 Analog-to-digital converters (ADCs) 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. 36/357 DS12110 Rev 10 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.

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. 3.21 Ultra-low-power comparators (COMP) STM32H742xI/G and STM32H743xI/G devices embed two rail-to-rail comparators (COMP1 and COMP2). They feature programmable reference voltage (internal or external), hysteresis and speed (low speed for low-power) as well as selectable output polarity. The reference voltage can be one of the following: • An external I/O • A DAC output channel • An internal reference voltage or submultiple (1/4, 1/2, 3/4). All comparators can wake up from Stop mode, generate interrupts and breaks for the timers, and be combined into a window comparator. 3.22 Operational amplifiers (OPAMP) STM32H742xI/G and STM32H743xI/G devices embed two rail-to-rail operational amplifiers (OPAMP1 and OPAMP2) with external or internal follower routing and PGA capability. The operational amplifier main features are: 38/357 • PGA with a non-inverting gain ranging of 2, 4, 8 or 16 or inverting gain ranging of -1, -3, -7 or -15 • One positive input connected to DAC • Output connected to internal ADC • Low input bias current down to 1 nA • Low input offset voltage down to 1.5 mV • Gain bandwidth up to 7.3 MHz DS12110 Rev 10 STM32H742xI/G STM32H743xI/G Functional overview The devices embeds two operational amplifiers (OPAMP1 and OPAMP2) with two inputs and one output each. These three I/Os can be connected to the external pins, thus enabling any type of external interconnections. The operational amplifiers can be configured internally as a follower, as an amplifier with a non-inverting gain ranging from 2 to 16 or with inverting gain ranging from -1 to -15. 3.23 Digital filter for sigma-delta modulators (DFSDM) The devices embed one DFSDM with 4 digital filters modules and 8 external input serial channels (transceivers) or alternately 8 internal parallel inputs support. The DFSDM peripheral is dedicated to interface the external Σ∆ modulators to microcontroller and then to perform digital filtering of the received data streams (which represent analog value on Σ∆ modulators inputs). DFSDM can also interface PDM (Pulse Density Modulation) microphones and perform PDM to PCM conversion and filtering in hardware. DFSDM features optional parallel data stream inputs from internal ADC peripherals or microcontroller memory (through DMA/CPU transfers into DFSDM). DFSDM transceivers support several serial interface formats (to support various Σ∆ modulators).

The maximum timer clock is up to 480 MHz depending on TIMPRE bit in the RCC_CFGR register and D2PRE1/2 bits in RCC_D2CFGR register. 3.28.1 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. DS12110 Rev 10 43/357 54 Functional overview 3.28.2 STM32H742xI/G STM32H743xI/G 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. 3.28.3 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. • 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 full-featured general-purpose timers or used as simple timebases. 44/357 DS12110 Rev 10 STM32H742xI/G STM32H743xI/G 3.28.4 Functional overview 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. 3.28.5 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: 3.28.6 • 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 • Selectable clock source: • Internal clock source: LSE, LSI, HSI or APB clock • 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. 3.28.7 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. 3.28.8 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. DS12110 Rev 10 45/357 54 Functional overview 3.29 STM32H742xI/G STM32H743xI/G 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. 46/357 DS12110 Rev 10 STM32H742xI/G STM32H743xI/G 3.30 Functional overview Inter-integrated circuit interface (I2C) STM32H742xI/G and STM32H743xI/G devices embed four I2C interfaces. The I2C bus interface handles communications between the microcontroller and the serial I2C bus. It controls all I2C bus-specific sequencing, protocol, arbitration and timing. The I2C peripheral supports: • • 3.31 I2C-bus specification and user manual rev. 5 compatibility: – Slave and Master modes, multimaster capability – Standard-mode (Sm), with a bitrate up to 100 kbit/s – Fast-mode (Fm), with a bitrate up to 400 kbit/s – Fast-mode Plus (Fm+), with a bitrate up to 1 Mbit/s and 20 mA output drive I/Os – 7-bit and 10-bit addressing mode, multiple 7-bit slave addresses – Programmable setup and hold times – Optional clock stretching System Management Bus (SMBus) specification rev 2.0 compatibility: – Hardware PEC (Packet Error Checking) generation and verification with ACK control – Address resolution protocol (ARP) support – SMBus alert • Power System Management Protocol (PMBusTM) specification rev 1.1 compatibility • Independent clock: a choice of independent clock sources allowing the I2C communication speed to be independent from the PCLK reprogramming. • Wakeup from Stop mode on address match • Programmable analog and digital noise filters • 1-byte buffer with DMA capability Universal synchronous/asynchronous receiver transmitter (USART) STM32H742xI/G and STM32H743xI/G devices have four embedded universal synchronous 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. DS12110 Rev 10 47/357 54 Functional overview STM32H742xI/G STM32H743xI/G All USART have a clock domain independent from the CPU clock, allowing the USARTx to wake up the MCU from Stop mode.The wakeup from Stop mode is 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. All USART interfaces can be served by the DMA controller. Table 6.

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. 48/357 DS12110 Rev 10 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. DS12110 Rev 10 49/357 54 Functional overview 3.35 STM32H742xI/G STM32H743xI/G 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 • Communication using DMA for audio samples • Communication using DMA for control and user channel information • 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 Single wire protocol master interface (SWPMI) The Single wire protocol master interface (SWPMI) is the master interface corresponding to the Contactless Frontend (CLF) defined in the ETSI TS 102 613 technical specification. The main features are: • Full-duplex communication mode • automatic SWP bus state management (active, suspend, resume) • configurable bitrate up to 2 Mbit/s • automatic SOF, EOF and CRC handling SWPMI can be served by the DMA controller. 50/357 DS12110 Rev 10 STM32H742xI/G STM32H743xI/G 3.37 Functional overview Management Data Input/Output (MDIO) slaves The devices embed an MDIO slave interface it includes the following features: • – 32 x 16-bit firmware read/write, MDIO read-only output data registers – 32 x 16-bit firmware read-only, MDIO write-only input data registers • Configurable slave (port) address • Independently maskable interrupts/events: • 3.38 32 MDIO Registers addresses, each of which is managed using separate input and output data registers: – MDIO Register write – MDIO Register read – MDIO protocol error Able to operate in and wake up from Stop mode 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. 3.39 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.

OTG-HS1 supports both full-speed and high-speed operations, while OTG-HS2 supports only full-speed operations. They both integrate the transceivers for full-speed operation (12 Mbit/s) and are able to operate from the internal HSI48 oscillator. OTG-HS1 features a UTMI low-pin interface (ULPI) for high-speed operation (480 Mbit/s). When using the USB OTG-HS1 in HS mode, an external PHY device connected to the ULPI is required. The USB OTG HS peripherals are compliant with the USB 2.0 specification and with the OTG 2.0 specification. They have software-configurable endpoint setting and supports suspend/resume.

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.

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 13. 6.1.5 Pin input voltage The input voltage measurement on a pin of the device is described in Figure 14.

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 DS12110 Rev 10 103/357 320 Electrical characteristics (rev Y) STM32H742xI/G STM32H743xI/G device. It is not recommended to remove filtering capacitors to reduce PCB size or cost. This might cause incorrect operation of the device. 6.1.7 Current consumption measurement Figure 16.

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
