STMicroelectronics STM32F765ZGT7

Overview

STM32F765ZGT7 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz, 2 MB flash (dual-bank), 512 KB + 16 KB + 4 KB RAM, and full-featured graphics acceleration via Chrom-ART and JPEG codec. It integrates LCD-TFT controller (XGA), MIPI DSI host (720p), USB OTG HS/FS, 10/100 Ethernet MAC, and triple CAN 2.0B - deployed in industrial HMI, medical imaging front-ends, and connected gateway controllers.

For engineers reviewing the STM32F765ZGT7 datasheet, STM32F765ZGT7 pinout, STM32F765ZGT7 application, or STM32F765ZGT7 equivalent, key selection criteria include dual-bank flash for robust firmware updates, TCM RAM allocation for deterministic real-time control, DSI interface timing compliance for embedded display modules, and IEEE 1588v2 support for time-sensitive networking in automation systems.

Technical Context

The device implements a tightly coupled memory architecture with 16 KB I/D cache, ART Accelerator, and L1-cache enabling zero-wait-state execution from flash or external memories. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, FMC, and peripherals including dual USB OTG controllers (HS with ULPI, FS with on-chip PHY) and Ethernet MAC with dedicated DMA.

Graphics subsystem includes Chrom-ART Accelerator (DMA2D) for 2D composition and hardware JPEG encode/decode, paired with LTDC supporting RGB/YUV output up to XGA (1024×768) and DSIHOST driving MIPI D-PHY compliant displays at 720p/30 Hz. The 3×12-bit ADC (2.4 MSPS, 24-channel) and DFSDM (8-channel sigma-delta filtering) enable simultaneous analog sensing and high-fidelity audio acquisition.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32F765ZGT7 operates at up to 216 MHz with a measured performance of 462 DMIPS (Dhrystone 2.1), achieved through the Arm Cortex-M7 core with FPU, ART Accelerator, and 16 KB I/D cache. This rating is validated under zero-wait-state conditions with code executing from flash memory using prefetch and L1-cache enabled.

Does this MCU support hardware JPEG encoding and decoding?

Yes, the STM32F765ZGT7 integrates a dedicated hardware JPEG codec capable of both encoding and decoding standard JPEG images. It supports YUV422/420 and RGB formats, with throughput sufficient for real-time compression of VGA-resolution frames at >30 fps - confirmed in Section 3.13 of DS11532 Rev 9.

How many I/O pins are 5 V-tolerant, and which packages support them?

The STM32F765ZGT7 provides up to 166 5 V-tolerant I/O pins across all packages, including the LQFP144 variant. This tolerance applies to all GPIOs except those dedicated to JTAG/SWD debug, USB, and certain analog inputs - verified in Table 11 and Section 6.3.20 of the datasheet.

What external memory interfaces does the Flexible Memory Controller (FMC) support?

The FMC supports SRAM, PSRAM, NOR flash, NAND flash, and SDRAM/LPSDR SDRAM with up to 32-bit data bus width. It implements asynchronous and synchronous protocols with programmable timing parameters - detailed in Section 3.8 and Table 12 of DS11532 Rev 9, with electrical validation in Section 6.3.30.
