STMicroelectronics STM32F769IGT6

Overview

STM32F769IGT6 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 advanced graphics acceleration via Chrom-ART (DMA2D) and hardware JPEG codec. It integrates MIPI DSI host controller (720p30), LCD-TFT controller (XGA), USB OTG HS/FS, 10/100 Ethernet MAC, and triple CAN 2.0B - deployed in industrial HMI, medical imaging terminals, and automotive infotainment displays.

For engineers reviewing the STM32F769IGT6 datasheet, STM32F769IGT6 pinout, STM32F769IGT6 application, or STM32F769IGT6 equivalent, key selection criteria include dual-bank flash for seamless firmware updates, 128 KB data TCM RAM for deterministic real-time processing, MIPI DSI timing compliance (HS clock up to 500 Mbps), and IEEE 1588v2 support for synchronized networked control systems.

Technical Context

The STM32F769IGT6 implements a tightly coupled memory architecture with separate 16 KB I/D L1 caches and ART Accelerator, enabling zero-wait-state execution from flash or external memories. Its AXI-AHB bus matrix supports concurrent access by CPU, DMA, and peripherals - critical for simultaneous display rendering (LTDC + DSIHOST), Ethernet packet handling, and audio streaming (SAI + SPDIFRX).

Graphics subsystem integration includes dedicated LTDC controller with alpha blending and layer composition, DMA2D hardware blitter for fast bitmap operations, and DSIHOST supporting 1-lane or 2-lane D-PHY mode with configurable LP/HS transition timing per MIPI D-PHY v1.2. The USB OTG HS interface uses a dedicated DMA channel and ULPI interface, while the Ethernet MAC includes hardware timestamping and MII/RMII PHY support.

FAQ

What is the maximum operating frequency and associated performance metric for the STM32F769IGT6?

The STM32F769IGT6 operates at up to 216 MHz with an Arm Cortex-M7 core, achieving 462 DMIPS (Dhrystone 2.1) and 2.14 DMIPS/MHz. This performance level is sustained via 16 KB I/D L1 caches and the ART Accelerator, enabling zero-wait-state execution from flash or external memory - verified under full industrial temperature range (–40°C to +105°C) with VDD = 3.3 V.

Does the STM32F769IGT6 support hardware-accelerated JPEG encoding and decoding?

Yes, the STM32F769IGT6 integrates a dedicated hardware JPEG codec supporting baseline JPEG (YUV422/420) encode and decode. It processes 640×480 frames at up to 30 fps and 720p at ~25 fps, offloading the CPU entirely. The codec operates independently of the CPU and supports DMA-based data flow - confirmed in Section 3.13 of DS11532 Rev 9.

What are the key differences between the STM32F769IGT6 and STM32F767ZGT6 in terms of display interface capability?

The STM32F769IGT6 includes a full MIPI DSI host controller supporting 1- or 2-lane D-PHY operation up to 720p30, while the STM32F767ZGT6 lacks DSI and only supports parallel LCD-TFT (up to XGA). Additionally, the F769IGT6 integrates the Chrom-ART Accelerator (DMA2D) and hardware JPEG codec - features absent in the F767ZGT6 - making it uniquely suited for high-resolution, low-CPU-load display applications.

Which external memory types are supported by the Flexible Memory Controller (FMC) on the STM32F769IGT6?

The FMC supports SRAM, PSRAM, NOR flash, NAND flash, and SDRAM/LPSDR SDRAM with up to 32-bit data bus width. It implements standard timing protocols including asynchronous SRAM, burst-mode PSRAM, and synchronous SDRAM commands (e.g., auto-refresh, precharge). Configuration is done via dedicated FMC registers - detailed in Section 3.8 and Table 12 of DS11532 Rev 9.
