STMicroelectronics STM32F767ZIT6

Overview

STM32F767ZIT6 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, 3× 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 STM32F767ZIT6 datasheet, STM32F767ZIT6 pinout, STM32F767ZIT6 application, or STM32F767ZIT6 equivalent, key selection considerations include dual-bank flash for safe firmware updates, hardware JPEG codec acceleration, 168 I/Os with 108 MHz toggle rate, and deterministic real-time execution via instruction/data TCM RAM and ART Accelerator.

Technical Context

The STM32F767ZIT6 implements a tightly coupled Arm Cortex-M7 core with dual 16 KB L1 caches (I/D), ART Accelerator enabling zero-wait-state execution from flash, and MPU for memory protection. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, and peripherals including FMC, DMA2D, and Ethernet MAC.

It integrates heterogeneous communication stacks: three bxCAN controllers supporting ISO 11898-1, dual USB OTG (FS with on-chip PHY + HS with ULPI interface), IEEE 1588v2-compliant Ethernet MAC with dedicated DMA, and MIPI D-PHY compliant DSI host supporting up to 720p@30 Hz - all synchronized via multiple PLLs (main PLL, PLLI2S, PLLSAI) with independent clock domains.

FAQ

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

The STM32F767ZIT6 achieves 216 MHz maximum CPU frequency using its internal PLL with external 4–26 MHz crystal input. This requires proper VCAP1/VCAP2 capacitor placement (2.2 µF each) and stable 1.7–3.6 V supply. The ART Accelerator and dual 16 KB L1 caches ensure zero-wait-state execution at full speed from flash or SRAM.

Does STM32F767ZIT6 support USB High-Speed device mode without an external PHY?

No - USB OTG High-Speed mode requires an external ULPI PHY connected to the dedicated ULPI interface (PC10–PC12, PD0–PD7, PA5). However, Full-Speed device/host/OTG mode uses the integrated on-chip PHY and needs no external components beyond standard USB termination resistors.

How does the dual-bank flash architecture improve firmware update safety?

Dual-bank flash allows one bank to remain active while the other is erased and reprogrammed - enabling atomic firmware updates with rollback capability. This prevents bricking during power loss and supports A/B firmware partitioning required by IEC 62443 and UL 60730 functional safety standards.

What display interfaces does STM32F767ZIT6 natively support?

The device integrates a parallel LCD-TFT controller supporting up to XGA (1024×768) resolution and a MIPI DSI host controller supporting up to 720p@30 Hz. It does not include HDMI or LVDS transmitters - those require external bridge ICs, though HDMI-CEC is supported for remote control signaling.
