STMicroelectronics STM32H750VBT6TR

Overview

STM32H750VBT6TR 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-128/192/256, HASH, RNG). It delivers 1027 DMIPS and supports dual-domain power management (D1/D2/D3) for high-performance real-time control in industrial motor drives.

For engineers reviewing the STM32H750VBT6TR datasheet, STM32H750VBT6TR pinout, STM32H750VBT6TR application, or STM32H750VBT6TR equivalent, key selection criteria include its 480 MHz Cortex-M7 core with L1 cache, 168 GPIOs with interrupt capability, dual-mode Quad-SPI interface (133 MHz), FMC support for SDRAM/NOR/PSRAM, and hardware JPEG codec for embedded vision preprocessing.

Technical Context

The STM32H750VBT6TR implements a three-domain power architecture (D1 for CPU/peripherals, D2 for comms/timers, D3 for reset/clock/PMU), enabling independent clock gating and voltage scaling across six configurable ranges. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges, ensuring deterministic latency for time-critical tasks.

It integrates four DMA controllers-including a high-speed MDMA with linked-list support-and features three PLLs (system + two kernel clocks) with fractional mode for precise clock tree synthesis. The device supports crystal-less USB OTG via internal HSI48 and LPM/BCD, eliminating external crystal requirements for cost-sensitive designs.

FAQ

What is the maximum operating frequency of the STM32H750VBT6TR's Cortex-M7 core?

The STM32H750VBT6TR's Arm Cortex-M7 core runs at up to 480 MHz with full L1 instruction and data cache enabled. This frequency is achievable under VDD = 3.3 V and ambient temperature ≤85°C, as validated in DS12556 Rev 8 Section 6.3.1. The core maintains 1027 DMIPS performance and 2.14 DMIPS/MHz efficiency per Dhrystone 2.1 benchmark.

Does the STM32H750VBT6TR support external SDRAM, and what interface is used?

Yes, the STM32H750VBT6TR supports external SDRAM via its Flexible Memory Controller (FMC), which provides a 16-bit or 32-bit data bus with programmable timing. It supports LPDDR/SDR SDRAM up to 133 MHz in synchronous mode, with dedicated control signals including RAS, CAS, WE, and BA0–BA2, as detailed in Section 3.15 of the datasheet.

How many independent CAN FD interfaces does the STM32H750VBT6TR provide?

The STM32H750VBT6TR integrates two fully independent CAN FD controllers (FDCAN1 and FDCAN2), each supporting bit rates up to 5 Mbps, ISO 11898-1:2015 compliance, and time-triggered communication modes. Both controllers feature dedicated message RAM, filters, and loopback self-test capability per Section 3.40 of DS12556 Rev 8.

Is the STM32H750VBT6TR pin-compatible with other STM32H750 variants in the same package?

Yes, the STM32H750VBT6TR is pin-compatible with STM32H750ZB, IB, and XB variants in LQFP100 packages. All share identical pin assignments, electrical characteristics, and peripheral mapping-differing only in flash size (128 KB), RAM layout, and optional features like JPEG codec presence, as confirmed in Section 8.2 of the datasheet.
