STMicroelectronics STM32F767VGT7

Overview

STM32F767VGT7 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM), USB OTG HS/FS, Ethernet MAC, LCD-TFT controller, and MIPI DSI host. It serves as the central application processor in industrial HMI, medical imaging front-ends, and networked edge gateways requiring real-time graphics and deterministic communication.

For engineers reviewing the STM32F767VGT7 datasheet, STM32F767VGT7 pinout, STM32F767VGT7 application, or STM32F767VGT7 equivalent, key selection considerations include its dual-bank flash for safe firmware updates, 168 I/Os with 108 MHz toggle rate, hardware JPEG codec for embedded vision preprocessing, and IEEE 1588v2 support for time-sensitive networking.

Technical Context

The device integrates an ART Accelerator™ with 16 KB I/D cache enabling zero-wait-state execution from flash or external memory, and employs an AXI-AHB bus matrix to decouple CPU, DMA, and peripheral bandwidth. Its memory subsystem includes dedicated instruction/data TCM RAM for latency-critical routines and a flexible external memory controller supporting SDRAM, NOR, and NAND.

Peripherals are architected for concurrent high-throughput operation: dual USB OTG controllers (one HS with ULPI, one FS with on-chip PHY), triple CAN 2.0B interfaces, two SAIs for multi-channel audio, and a Chrom-ART Accelerator (DMA2D) offloading 2D graphics composition from the CPU-enabling smooth XGA-resolution UI rendering without frame buffer CPU polling.

FAQ

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

The STM32F767VGT7 achieves 216 MHz maximum CPU frequency using the internal PLL with a 4–26 MHz crystal oscillator input. This requires proper configuration of the voltage regulator (VOS scale 1), stable 1.2 V core supply via VCAP1/VCAP2 decoupling, and enabling the ART Accelerator with L1 cache. The 462 DMIPS rating is measured per Dhrystone 2.1 benchmark under these conditions.

Does this MCU support secure boot and cryptographic operations?

Yes - the STM32F767VGT7 includes a True Random Number Generator (RNG), CRC calculation unit, and supports secure firmware installation via the built-in ROM bootloader (activated by BOOT0). While it lacks a dedicated cryptographic accelerator, AES-128/256 and SHA-1/256 can be implemented in software using the FPU and TCM RAM for performance-critical keys and certificates.

Can the LCD-TFT controller drive displays without external components?

Yes - the integrated LCD-TFT controller supports parallel RGB (up to 24-bit) with programmable timing (HSYNC/VSYNC/DE) and direct connection to common TFT panels. No external display controller or video RAM is needed for resolutions up to XGA (1024×768), though external SDRAM via FMC may be used for larger frame buffers or dual-display configurations.

What debug interfaces are supported and what trace capability exists?

The device supports SWD and JTAG interfaces for debugging and programming. It also integrates the Cortex-M7 Trace Macrocell™ (ETM), enabling instruction and data trace via SWO or dedicated trace port - allowing cycle-accurate profiling and real-time analysis of interrupt latency, cache hits/misses, and peripheral DMA activity in complex real-time applications.
