STMicroelectronics STM32H743VGH6

Overview

STM32H743VGH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M7 microcontroller operating at up to 480 MHz, featuring 2 MB flash, 1 MB RAM (including 192 KB TCM), dual CAN FD interfaces, and hardware JPEG codec. It serves as a high-performance application processor in industrial HMI, motor control gateways, and real-time vision edge nodes.

For engineers reviewing the STM32H743VGH6 datasheet, STM32H743VGH6 pinout, STM32H743VGH6 application, or STM32H743VGH6 equivalent, key selection considerations include its triple PLL clock architecture, 168 GPIOs with interrupt capability, 3× 16-bit ADCs (3.6 MSPS), LCD-TFT controller with XGA support, and voltage scaling across six Run/Stop modes.

Technical Context

The STM32H743VGH6 implements a three-domain power architecture (D1/D2/D3) enabling independent clock gating and domain shutdown-critical for deterministic real-time execution in mixed-criticality systems. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges, supporting concurrent high-bandwidth peripheral access without CPU contention.

It integrates four DMA controllers-including a high-speed MDMA with linked-list support-and features a dedicated 2.1 ns-resolution high-resolution timer (HRTIM1) for precise PWM generation in digital power supplies and servo drives, alongside hardware-accelerated Chrom-ART (DMA2D) and JPEG codec for embedded graphics offload.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32H743VGH6 achieves 480 MHz via its main PLL configured with fractional-N synthesis, fed by either the 4–48 MHz HSE crystal or 64 MHz HSI oscillator. This requires proper VDD voltage scaling (Range 0 or 1), stable VCAP capacitor placement, and adherence to flash wait-state settings per the AC characteristics table in DS12110 Rev 11 Section 6.3.11.

Does STM32H743VGH6 support external SDRAM, and what interface is used?

Yes-it supports up to 32-bit wide SDRAM/LPSDR SDRAM through the Flexible Memory Controller (FMC), clocked up to 100 MHz in synchronous mode. The FMC provides dedicated address/control signals and supports burst reads/writes, refresh management, and programmable timing parameters for JEDEC-compliant DDR1/DDR2/LPSDR devices.

How many independent ADCs does it have, and what is their combined sampling capability?

It integrates three independent 16-bit ADCs (ADC1/2/3), each supporting up to 36 channels and 3.6 MSPS in interleaved mode. With simultaneous sampling across all three, the device achieves up to 10.8 MSPS aggregate throughput-enabling high-fidelity current/voltage sensing in multi-axis motor drives or power quality analyzers.

Is the LQFP100 package RoHS-compliant and lead-free?

Yes-the STM32H743VGH6 in LQFP100 (14 × 14 mm) is RoHS-compliant and lead-free, certified under ST's ECOPACK2 environmental standard. The package uses matte tin terminal finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for standard surface-mount assembly processes.
