STMicroelectronics STM32H750VBT6

Overview

STM32H750VBT6 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), and integrated cryptographic acceleration (AES-256, HASH, RNG). It supports dual-domain power management (D1/D2/D3), includes three PLLs with fractional mode, and targets high-performance industrial control and real-time edge processing applications.

For engineers reviewing the STM32H750VBT6 datasheet, STM32H750VBT6 pinout, STM32H750VBT6 application, or STM32H750VBT6 equivalent, key selection considerations include its 480 MHz CPU frequency, 1 Mbyte RAM architecture (ITCM/DTCM/backup SRAM), dual CAN FD interfaces, hardware JPEG codec, and LQFP100 package with 86 I/Os - all critical for deterministic real-time systems requiring secure firmware updates and low-latency analog acquisition.

Technical Context

The STM32H750VBT6 implements a dual-bus matrix architecture (1 AXI + 2 AHB) with five AHB2-APB bridges and two AXI2-AHB bridges, enabling concurrent high-bandwidth peripheral access. Its memory subsystem integrates 16 Kbytes instruction and 16 Kbytes data L1 cache, plus configurable voltage scaling across six ranges in Run/Stop modes.

It features three independent PLLs: one system clock PLL (up to 480 MHz), and two kernel-clock PLLs supporting asynchronous peripheral clocking - essential for isolating USB HS, Ethernet, and audio timing domains. The interconnect matrix and four DMA controllers (including MDMA with linked-list support) offload CPU-intensive data movement from ADC, SDMMC, and Quad-SPI peripherals.

FAQ

What is the maximum operating frequency of the STM32H750VBT6 CPU core?

The STM32H750VBT6 features an Arm Cortex-M7 core rated for up to 480 MHz operation under specified voltage and temperature conditions. This frequency is achieved using the main PLL with fractional mode and requires proper VCAP decoupling and thermal management. Dhrystone benchmark yields 1027 DMIPS at this speed, confirming sustained high-throughput execution capability.

Does the STM32H750VBT6 support hardware-accelerated JPEG encoding and decoding?

Yes, the STM32H750VBT6 integrates a dedicated hardware JPEG codec capable of real-time encoding and decoding of JPEG images up to QVGA resolution. It operates independently of the CPU, uses DMA for pixel data transfer, and supports YUV422 and RGB565 formats - confirmed in Section 3.26 of the DS12556 datasheet.

How many independent power domains does the STM32H750VBT6 implement, and what are their roles?

The STM32H750VBT6 implements three independent power domains: D1 (high-performance computing domain), D2 (communication and timer peripherals), and D3 (reset/clock/power management). Each can be clock-gated or powered down individually, enabling fine-grained power optimization - for example, keeping D3 active for RTC while shutting down D1/D2 in Standby mode.

What are the key differences between the STM32H750VBT6 and STM32H743VIT6 in LQFP100 packages?

The STM32H750VBT6 has 128 KB flash and includes hardware JPEG codec; the STM32H743VIT6 offers 512 KB flash but omits JPEG acceleration. Both share identical LQFP100 pinout, 1 MB RAM, Cortex-M7 core, and peripheral sets. The H743 supports larger firmware images and complex GUI stacks, while the H750 prioritizes vision-edge acceleration within tighter memory constraints.
