STMicroelectronics STM32F750N8H6

Overview

STM32F750N8H6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, operating at up to 216 MHz (462 DMIPS), featuring 64 KB Flash, 320+16+4 KB SRAM (including TCM and backup RAM), USB OTG HS/FS, Ethernet MAC, LCD-TFT controller, and cryptographic acceleration (AES, SHA, RNG). It targets embedded HMI, industrial control, and connected edge devices requiring real-time graphics and secure connectivity.

For engineers reviewing the STM32F750N8H6 datasheet, STM32F750N8H6 pinout, STM32F750N8H6 application, or STM32F750N8H6 equivalent, this page delivers verified technical context, validated pin functions, confirmed low-power mode behavior, and documented alternative MCU options for migration or second-sourcing in resource-constrained, safety-aware, or graphics-intensive designs.

Technical Context

The STM32F750N8H6 integrates an adaptive real-time accelerator (ART Accelerator™) and dual 4-KB L1 caches (instruction/data), enabling zero-wait-state execution from Flash and external memories. Its AXI-AHB bus matrix supports concurrent high-bandwidth access across CPU, DMA2D, Ethernet, and FMC peripherals.

It implements dual USB controllers (OTG_FS + OTG_HS with dedicated DMA and ULPI support), IEEE 1588v2-compliant 10/100 Ethernet MAC, and a Chrom-ART Accelerator™ (DMA2D) for hardware-accelerated 2D graphics composition - all synchronized via a multi-source clock system with three PLLs (main, audio, SAI) and independent 32 kHz RTC oscillator.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32F750N8H6 operates at up to 216 MHz with a measured performance of 462 DMIPS (Dhrystone 2.1), achieving 2.14 DMIPS/MHz. This rating was obtained under conditions of ART Accelerator™ and L1 cache enabled, executing from Flash memory with zero wait states - confirmed in Section 2.1 of DS12535 Rev 2.

Does STM32F750N8H6 support external SDRAM, and what interface is used?

Yes, it supports external SDRAM up to LPSDR/LPDDR via the Flexible Memory Controller (FMC) with a configurable 32-bit data bus. The FMC provides dedicated control signals (RAS/CAS/WE/CLK) and supports burst lengths up to 8, as specified in Section 3.8 and Table 47 of the datasheet.

How many I/O pins are 5 V-tolerant, and which voltage domains do they belong to?

Up to 166 I/O pins are 5 V-tolerant, covering all GPIO ports except those assigned to USB, JTAG/SWD debug, and certain analog inputs (e.g., ADC, VREF+). These pins operate safely with 5 V signals while powered from a 1.7–3.6 V VDD supply - verified in Section 6.3.17 and Table 17 of DS12535 Rev 2.

What low-power modes retain RTC functionality and backup SRAM content?

Standby mode retains RTC operation, 32×32-bit backup registers, and 4 KB backup SRAM when powered by VBAT. Stop mode also preserves RTC and backup registers but powers down backup SRAM unless VBAT is applied - detailed in Sections 3.20 and 3.19, with current consumption values in Tables 30 and 31.
