STMicroelectronics STM32H750XBH6U

Overview

STM32H750XBH6U from STMicroelectronics is a 32-bit Arm® Cortex®-M7 microcontroller operating at up to 480 MHz, featuring 128 Kbytes of flash, 1 Mbyte of RAM (including 192 Kbytes TCM), dual-mode Quad-SPI, and hardware crypto acceleration (AES-256, SHA-2, RNG). It integrates 3× 16-bit ADCs (3.6 MSPS), 2× DACs, 2× op-amps (7.3 MHz), and supports CAN FD and Ethernet MAC for industrial real-time control systems.

For engineers reviewing the STM32H750XBH6U datasheet, STM32H750XBH6U pinout, STM32H750XBH6U application, or STM32H750XBH6U equivalent, key selection considerations include its triple PLL clock system with fractional mode, voltage scaling across 6 ranges, 2.95 µA Standby power with RTC/LSE active, and UFBGA176+25 (10×10 mm) package with 168 GPIOs supporting interrupt capability.

Technical Context

The STM32H750XBH6U implements a three-domain power architecture (D1/D2/D3), enabling independent clock gating and power switching for high-performance, communication/peripheral, and reset/clock/power management subsystems. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges, supporting deterministic latency for time-critical firmware execution.

It features four DMA controllers-including one high-speed MDMA with linked-list support-and integrates a Chrom-ART Accelerator (DMA2D) plus hardware JPEG codec to offload graphics processing from the CPU. The analog subsystem includes DFSDM (8-channel/4-filter), DCMI (80 MHz), and LCD-TFT controller supporting XGA resolution.

Key Specifications

Pinout & Package

STM32H750XBH6U uses a 176-ball UFBGA package with 25 additional balls for VSS/VDD decoupling (A0E7 marking), optimized for high-density PCB layouts and thermal performance in industrial environments. Pin assignment follows ST's standardized STM32H750XB pin mapping with dedicated VCAP, VREF+, and VBAT rails.

FAQ

What is the maximum operating frequency and core configuration of the STM32H750XBH6U?

The STM32H750XBH6U features a single Arm Cortex-M7 core running at up to 480 MHz with double-precision floating-point unit, 16 KB instruction cache, and 16 KB data cache. It achieves 1027 DMIPS (2.14 DMIPS/MHz) per Dhrystone 2.1 benchmark and includes a Memory Protection Unit (MPU) for secure task isolation in RTOS environments.

Does the STM32H750XBH6U support external SDRAM, and what interface is used?

Yes, the STM32H750XBH6U supports external SDRAM and LPDDR SDRAM via its Flexible Memory Controller (FMC), which provides a configurable 32-bit data bus. The FMC operates in synchronous mode up to 133 MHz and supports SDRAM initialization sequences, refresh control, and burst access modes required for display frame buffers or large data caches.

How many ADC channels does the STM32H750XBH6U support, and what is their maximum sampling rate?

The device integrates three independent 16-bit ADCs supporting up to 36 total channels (with multiplexing) and a combined maximum sampling rate of 3.6 MSPS. Each ADC supports hardware oversampling, analog watchdogs, and injected/conversion sequencing-enabling simultaneous high-fidelity acquisition across motor phase currents, temperature sensors, and voltage rails.

Is the STM32H750XBH6U pin-compatible with other STM32H750 variants, and what package options exist?

Yes, the STM32H750XBH6U in UFBGA176+25 (10×10 mm) is pin-compatible with STM32H750IBK6 (LQFP176) and STM32H750VBT6 (LQFP100) within the same memory/peripheral configuration group. Other packages include LQFP144, TFBGA240+25, and LQFP176-all sharing identical signal mapping and electrical characteristics per datasheet DS12556 Rev 8.
