STMicroelectronics STM32H750IBT6

Overview

STM32H750IBT6 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, motor drive, and real-time signal processing applications.

For engineers reviewing the STM32H750IBT6 datasheet, STM32H750IBT6 pinout, STM32H750IBT6 application, or STM32H750IBT6 equivalent, key selection considerations include its 480 MHz M7 core with L1 cache, 168 GPIOs with interrupt capability, dual-mode Quad-SPI interface (133 MHz), FMC for SDRAM/NOR/PSRAM, and hardware JPEG codec for embedded vision systems.

Technical Context

The STM32H750IBT6 implements a tightly coupled memory architecture with separate ITCM (64 KB) and DTCM (128 KB) for deterministic real-time execution, alongside 864 KB user SRAM and 4 KB backup SRAM. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges, enabling concurrent peripheral access without CPU contention.

It integrates four DMA controllers-including a high-speed MDMA with linked-list support-and features a dedicated Ethernet MAC with DMA, dual CAN FD controllers, and an LCD-TFT controller supporting XGA resolution. The device uses a 3-domain power architecture (D1/D2/D3) with independent clock gating and voltage scaling across six configurable ranges.

FAQ

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

The STM32H750IBT6 achieves 480 MHz via its Arm Cortex-M7 core with dual-issue superscalar pipeline and L1 instruction/data caches (16 KB each). This frequency requires proper VDD/VDDA regulation, VCAP capacitor placement per datasheet layout guidelines, and use of the main PLL with HSE or HSI as source. Voltage scaling must be set to Range 0 (1.2 V) in Run mode.

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

Yes, the STM32H750IBT6 supports external SDRAM through its Flexible Memory Controller (FMC) with 16-bit data bus and address multiplexing. It supports single-data-rate (SDR) SDRAM and low-power SDR SDRAM (LPSDR) with programmable timing parameters, enabling up to 125 MHz clock operation and seamless integration with standard 64 MB modules.

How many independent ADCs are integrated, and what is their maximum sampling rate?

The device integrates three independent 16-bit ADCs (ADC1, ADC2, ADC3), each capable of up to 3.6 MSPS in interleaved mode. They share common calibration and support simultaneous sampling across up to 36 channels, with hardware oversampling and digital filtering for enhanced resolution in precision measurement applications.

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

Yes, the STM32H750IBT6 in LQFP100 package is ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. It is lead-free, halogen-free, and uses matte tin terminal finish with NiPdAu underplate for reliable solderability and long-term reliability.
