STMicroelectronics STM32F767BIT6

Overview

STM32F767BIT6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM), and integrated peripherals including USB OTG HS/FS, Ethernet MAC, LCD-TFT controller, MIPI DSI host, and three CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and networked motor control systems.

For engineers reviewing the STM32F767BIT6 datasheet, STM32F767BIT6 pinout, STM32F767BIT6 application, or STM32F767BIT6 equivalent, key selection criteria include dual-bank flash for robust firmware updates, 128 KB data TCM RAM for deterministic real-time processing, hardware JPEG codec for embedded vision preprocessing, and IEEE 1588v2 support for time-sensitive networking in industrial automation.

Technical Context

The STM32F767BIT6 implements a tightly coupled Arm Cortex-M7 core with ART Accelerator and 16 KB I/D cache, enabling zero-wait-state execution from flash or external memory. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, and peripherals including FMC, DSI, and Ethernet MAC.

It integrates dual-mode Quad-SPI for XIP and memory-mapped external flash, Chrom-ART Accelerator (DMA2D) for GPU-like 2D graphics composition, and a dedicated audio subsystem with two SAIs, SPDIFRX, and PLLI2S/PLLSAI for multi-channel synchronized audio processing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Compared with STM32F767BIT6, the STM32H743VIT6 offers higher compute throughput and dual-core flexibility but removes JPEG hardware acceleration critical for imaging; the STM32F769NIK6 trades FMC and flash size for ultra-compact packaging and built-in display driving - making it unsuitable for external frame buffers or large OTA images.

FAQ

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

The STM32F767BIT6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB I/D cache, which eliminate flash wait states. Stable operation requires proper decoupling of VCAP1/VCAP2 with 2.2 µF capacitors and a clean 1.7–3.6 V supply. The internal 16 MHz RC oscillator is factory-trimmed to ±1% accuracy, but for full-speed operation, an external 4–26 MHz crystal is recommended to feed the PLL.

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

Yes, the STM32F767BIT6 supports external SDRAM up to 256 MB using its Flexible Memory Controller (FMC) with a 32-bit data bus and dedicated SDRAM command signals (CK, CKE, CAS, RAS, WE). It supports both standard SDRAM and low-power variants (LPDDR/PSRAM), enabling use as a frame buffer for high-resolution displays or as extended runtime memory for complex control algorithms.

How does the dual-bank flash architecture improve firmware reliability?

Dual-bank flash allows one bank to remain active while the other is erased and reprogrammed - enabling true background firmware updates without halting application execution. This architecture supports secure boot validation (each bank can hold independent signed images), rollback recovery, and atomic firmware swaps - critical for medical and industrial systems requiring zero-downtime maintenance and regulatory compliance.

Can the MIPI DSI host interface drive standard display modules without additional components?

Yes, the integrated MIPI DSI host (DSIHOST) supports D-PHY v1.2 with LP/HS mode switching and programmable lane count (1–4 data lanes + clock). It directly interfaces with standard MIPI DSI display modules (e.g., 720p panels at 30 Hz), eliminating the need for external bridge ICs. Required external components are limited to termination resistors (100 Ω differential) and optional ESD protection diodes on DSI lanes.
