STMicroelectronics STM32F767ZGT6

Overview

STM32F767ZGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, 2 MB dual-bank flash, 512 KB SRAM (including 128 KB data TCM), USB OTG HS/FS, and integrated LCD-TFT + MIPI DSI controllers. It serves as the main application processor in industrial HMI, medical imaging front-ends, and networked edge gateways requiring real-time graphics and multi-protocol connectivity.

For engineers reviewing the STM32F767ZGT6 datasheet, STM32F767ZGT6 pinout, STM32F767ZGT6 application, or STM32F767ZGT6 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-bank flash for seamless firmware updates, hardware JPEG codec, Ethernet MAC with IEEE 1588v2 support, and 100-pin LQFP package with 164 fast I/Os up to 108 MHz.

Technical Context

The STM32F767ZGT6 implements a tightly coupled memory architecture with separate 16 KB instruction and data caches, ART Accelerator enabling zero-wait-state execution from flash, and dual-bank flash supporting concurrent read-while-write operations. Its AXI-AHB bus matrix enables simultaneous high-bandwidth access by CPU, DMA, and peripherals including FMC, DSI, and Ethernet MAC.

It integrates three independent CAN 2.0B controllers, two SDMMC interfaces, SPDIFRX, HDMI-CEC, and dual SAIs for audio processing - all synchronized via multiple PLLs (main PLL, PLLI2S, PLLSAI) with dedicated clock trees for display, audio, and system domains. The DSI host controller supports up to 720p@30 Hz with embedded MIPI D-PHY.

FAQ

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

The STM32F767ZGT6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB I/D caches. This eliminates flash wait states, allowing zero-latency instruction fetch. Voltage must be ≥2.7 V, and VCAP1/VCAP2 capacitors (2.2 µF each) must be correctly placed per Section 6.3.2 of DS11532 Rev 9 to stabilize the internal regulator.

Does it support hardware encryption and secure boot?

Yes - it includes a true random number generator (RNG), CRC calculation unit, and supports secure firmware installation via STM32CubeProgrammer with AES-128 encrypted images. However, unlike the H7 series, it lacks dedicated cryptographic accelerators (AES, HASH, PKA); software libraries (STM32 Cryptographic Library) provide certified implementations.

Can the DSI interface drive a 1080p display?

No - the DSI host controller is rated for up to 720p@30 Hz (Section 3.47, DS11532 Rev 9). For 1080p, external bridge ICs (e.g., Parade PS8640) or migration to STM32H753/H757 with dual-display support is required. The LTDC controller supports XGA (1024×768) natively.

What debug interfaces are supported and what are their bandwidth limits?

SWD and JTAG are supported, with SWD being the default for production programming. The Cortex-M7 Trace Macrocell™ enables real-time instruction tracing at up to 100 MHz via 4-bit trace port. Full-speed trace requires external debugger (e.g., ST-LINK/V3 with trace buffer) and consumes dedicated GPIO pins (PB3/PB4 for SWO/TRACECLK).
