STMicroelectronics STM32F750Z8T6

Overview

STM32F750Z8T6 from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 64 KB flash, 320+16+4 KB RAM (including TCM and backup SRAM), USB OTG HS/FS, Ethernet MAC, dual CAN 2.0B, and LCD-TFT controller - deployed in industrial HMI, medical imaging front-ends, and connected gateway edge nodes.

For engineers reviewing the STM32F750Z8T6 datasheet, STM32F750Z8T6 pinout, STM32F750Z8T6 application, or STM32F750Z8T6 equivalent, key selection factors include L1 cache configuration (4 KB I-cache + 4 KB D-cache), Chrom-ART Accelerator™ for DMA2D graphics offload, dual-mode Quad-SPI interface, hardware crypto acceleration (AES-128/192/256, SHA-1/2, HMAC), and 168 GPIOs with 108 MHz toggle rate and 5 V tolerance on 166 pins.

Technical Context

The STM32F750Z8T6 integrates a dual-bank ART Accelerator™ enabling zero-wait-state execution from flash and external memories, paired with tightly coupled memory (TCM) architecture: 64 KB data TCM for real-time data and 16 KB instruction TCM for latency-critical routines. Its AXI-AHB bus matrix supports concurrent high-bandwidth access across CPU, DMA, and peripherals.

It implements two independent USB controllers (OTG_FS with on-chip PHY and OTG_HS with ULPI support and dedicated DMA), IEEE 1588v2-compliant 10/100 Ethernet MAC, and dual SAI audio interfaces with internal audio PLL - all synchronized via a multi-source clock system including HSE (4–26 MHz), HSI (16 MHz ±1%), and LSE (32.768 kHz RTC-calibrated).

FAQ

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

The STM32F750Z8T6 achieves 216 MHz via its Arm Cortex-M7 core with adaptive real-time accelerator (ART Accelerator™) and 4 KB instruction/data caches. This configuration enables zero-wait-state execution from flash memory and external memories, verified under 1.7–3.6 V supply and ambient temperatures up to 105°C per datasheet DS12535 Rev 2 Section 6.3.1.

Does this MCU support external SDRAM, and what interface is used?

Yes - the STM32F750Z8T6 supports external SDRAM through its Flexible Memory Controller (FMC), which provides a configurable 32-bit data bus with dedicated control signals (RAS/CAS/WE/CLK). It supports LPDDR/SDR SDRAM and includes hardware ECC for reliability, as specified in Section 3.8 and Table 11 of DS12535 Rev 2.

How many USB interfaces does the STM32F750Z8T6 integrate, and what are their capabilities?

It integrates two independent USB controllers: USB OTG FS with on-chip full-speed PHY, and USB OTG HS with ULPI interface and dedicated DMA channel. The HS controller supports 480 Mbit/s operation with external PHY, while FS supports device/host/OTG roles - both compliant with USB 2.0 specification per Sections 3.33–3.34 of DS12535 Rev 2.

Is the STM32F750Z8T6 qualified for extended temperature range operation?

Yes - the STM32F750Z8T6 is rated for industrial temperature range (–40°C to +105°C), validated per Section 6.3.1 of DS12535 Rev 2. This qualification covers all core functionality, including FMC, LTDC, DCMI, and crypto accelerators, with derated current consumption above 85°C as documented in Tables 23–32.
