STMicroelectronics STM32F767VIT6TR

Overview

STM32F767VIT6TR 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 SRAM (including 128 KB data TCM), and full-featured connectivity including USB OTG HS/FS, dual CAN 2.0B, 10/100 Ethernet MAC, MIPI DSI host, and LCD-TFT controller - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.

For engineers reviewing the STM32F767VIT6TR datasheet, STM32F767VIT6TR pinout, STM32F767VIT6TR application, or STM32F767VIT6TR equivalent, key selection criteria include dual-bank flash for seamless firmware updates, 216 MHz real-time execution with L1 cache, hardware JPEG codec for embedded vision, and 168 I/Os with 5 V tolerance - critical for robust industrial interface design and multi-peripheral integration.

Technical Context

The STM32F767VIT6TR 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 access to flash, SRAM, and peripherals, while the flexible memory controller (FMC) interfaces with SDRAM, NOR/NAND, and PSRAM up to 32-bit width.

Graphics acceleration is handled by the Chrom-ART DMA2D engine and dedicated JPEG codec, offloading CPU-intensive rendering tasks. The MIPI DSI host controller operates at up to 720p@30 Hz, and the dual USB OTG controllers (FS + HS with ULPI) support simultaneous device/host roles with dedicated DMA channels - essential for embedded multimedia and connectivity gateways.

FAQ

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

The STM32F767VIT6TR achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB L1 cache, which eliminate flash wait states. It requires a 4–26 MHz external crystal (PH0/PH1) feeding the PLL, with VCAP1/VCAP2 capacitors stabilizing the internal voltage regulator. This frequency is sustained across all operating voltage ranges (1.7–3.6 V) under industrial temperature conditions (–40°C to +85°C).

Does this MCU support hardware encryption or secure boot?

The STM32F767VIT6TR does not integrate dedicated cryptographic accelerators (AES, PKA, HASH) or tamper-detection features found in STM32L5 or H5 series. Secure boot relies on external mechanisms or software-based validation; however, it supports read-out protection (RDP) Level 1/2 and write protection for flash sectors to prevent unauthorized firmware extraction or modification.

Can the USB OTG HS interface operate without an external ULPI PHY?

No - the USB OTG HS interface requires an external ULPI PHY (e.g., SMSC USB334x or Microchip USB3300) connected via the ULPI bus (D0–D7, CLK, DIR, NXT, STP). The on-chip HS PHY is not present; only the full-speed PHY is integrated on-chip (PA11/PA12). HS operation is therefore dependent on correct external PHY layout and timing calibration.

What is the role of the 128 KB data TCM RAM and how is it allocated?

The 128 KB data TCM (Tightly Coupled Memory) RAM is a low-latency SRAM block directly connected to the Cortex-M7 core, used for time-critical data structures like real-time control buffers, interrupt stacks, and FOC coefficient tables. It is mapped to address 0x20000000 and accessed with zero-cycle latency - essential for deterministic execution in motor control or audio processing loops.
