STMicroelectronics STM32H743XGH6

Overview

STM32H743XGH6 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 integrates LCD-TFT controller, DFSDM, and high-resolution timer for real-time industrial HMI and motor control applications.

For engineers reviewing the STM32H743XGH6 datasheet, STM32H743XGH6 pinout, STM32H743XGH6 application, or STM32H743XGH6 equivalent, key selection criteria include dual-domain power management (D1/D2/D3), Quad-SPI interface timing (up to 133 MHz), Ethernet MAC + DMA support, and VBAT-backed RTC with sub-second accuracy.

Technical Context

The STM32H743XGH6 implements a triple-domain power architecture (D1 high-performance, D2 communication/timers, D3 reset/clock/PM) with independent voltage scaling across six ranges. Its interconnect matrix comprises one AXI and two AHB bus matrices, bridged by five AHB2-APB and two AXI2-AHB bridges.

It features three PLLs - one system clock PLL and two kernel-clock PLLs with fractional mode - enabling precise clock tree configuration for simultaneous high-speed peripherals (e.g., 125 MHz SDIO, 80 MHz DCMI, 150 MHz I2S). The MDMA controller supports linked-list DMA transfers to offload CPU during memory-intensive operations like JPEG encoding or TFT frame buffering.

Key Specifications

Pinout & Package

UFBGA169 package with 169 solder balls in 13 × 13 array (7 mm × 7 mm body, 0.65 mm ball pitch), compliant with JEDEC MO-276AA. Ball layout optimized for signal integrity in high-speed digital and mixed-signal routing.

FAQ

What is the maximum operating frequency of the STM32H743XGH6 core?

The Arm Cortex-M7 core operates at up to 480 MHz, validated across temperature (-40°C to +105°C) and voltage (1.62 V to 3.6 V) ranges per DS12110 Rev 11 Section 6.3.1. This frequency is achieved using the main PLL with HSE or HSI as source, and requires proper VCAP capacitor placement and thermal management per Section 8.10.

Does the STM32H743XGH6 support external SDRAM?

Yes - the Flexible Memory Controller (FMC) supports SDRAM/LPSDR SDRAM with up to 32-bit data bus and clock rates up to 100 MHz in synchronous mode. Configuration requires precise timing register setup (TRCD, TRP, etc.) and board-level impedance matching per Section 6.3.17.

How many CAN FD interfaces does the STM32H743XGH6 include?

The STM32H743XGH6 integrates two fully independent CAN FD controllers (FDCAN1 and FDCAN2), each supporting ISO 11898-1:2015 with bit rates up to 5 Mbps, programmable data phases, and dedicated message RAM. Both support loopback self-test and timestamping per Section 3.39.

Is the UFBGA169 package RoHS and REACH compliant?

Yes - all STM32H743XGH6 packages are ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free matte tin finish, halogen-free molding compound, and full material declarations are provided in ST's official ECOPACK2 documentation (Doc ID 28374).
