STMicroelectronics STM32F765VIH6

Overview

STM32F765VIH6 from STMicroelectronics is an Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, featuring 2 MB dual-bank flash, 512 KB SRAM (including 128 KB data TCM), USB OTG HS/FS, MIPI DSI host controller, and LCD-TFT controller supporting XGA resolution. It targets high-performance embedded applications such as industrial HMIs, medical imaging front-ends, and real-time motor control systems requiring deterministic execution and rich peripheral integration.

For engineers reviewing the STM32F765VIH6 datasheet, STM32F765VIH6 pinout, STM32F765VIH6 application, or STM32F765VIH6 equivalent, key selection considerations include its 216 MHz Cortex-M7 core with L1 cache, dual-bank flash for seamless firmware updates, hardware JPEG codec, Chrom-ART Accelerator for GUI rendering, and support for MIPI DSI displays up to 720p 30 Hz.

Technical Context

The STM32F765VIH6 implements a tightly coupled memory architecture with separate 16 KB I/D caches, ART Accelerator, and dual-bank flash enabling concurrent read-while-write operations - critical for over-the-air firmware updates in safety-aware systems. Its AXI-AHB bus matrix supports high-bandwidth peripherals including Ethernet MAC, SDMMC, and dual USB OTG controllers.

It integrates specialized accelerators: Chrom-ART (DMA2D) for 2D graphics composition, hardware JPEG encoder/decoder, and DFSDM for sigma-delta sensor interfacing. The MIPI D-PHY PLL and DSIHOST controller provide native support for low-power, high-speed display interfaces with precise timing control and lane synchronization.

FAQ

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

The STM32F765VIH6 achieves 216 MHz via its Arm Cortex-M7 core with ART Accelerator and 16 KB I/D caches, enabling zero-wait-state execution from flash. This frequency is sustained under industrial temperature conditions (–40°C to +85°C) with proper VCAP decoupling and thermal management per datasheet Section 7.2.

Does STM32F765VIH6 support MIPI DSI displays natively?

Yes - it integrates a full MIPI DSI host controller (DSIHOST) with D-PHY physical layer, supporting up to 4 data lanes and clock lane at 500 Mbps per lane. It drives displays up to 720p @ 30 Hz in video or command mode without external bridge ICs, as confirmed in Section 3.47 of DS11532 Rev 9.

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

Dual-bank flash allows one bank to remain active while the other is erased or reprogrammed - enabling atomic firmware updates with rollback capability. This prevents corruption during power loss and meets IEC 62443 and ISO 13849 functional safety requirements for industrial control systems.

What are the key differences between STM32F765VIH6 and STM32F767VIH6?

The STM32F765VIH6 includes MIPI DSI host and LCD-TFT controller but omits Ethernet PHY; the STM32F767VIH6 adds integrated Ethernet PHY and RMII/MII interface but removes DSI. Both share identical CPU, memory, and most peripherals - choice depends on display vs. Ethernet priority.
