STMicroelectronics STM32F469IGT6

Overview

STM32F469IGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 MCU with FPU and ART Accelerator™, operating at up to 180 MHz (225 DMIPS), featuring 2 MB dual-bank Flash, 384+4 KB SRAM (including 64 KB CCM), integrated Chrom-ART Accelerator™ for GUI rendering, MIPI DSI host controller (720p@30 Hz), and LCD-TFT controller (XGA). It targets embedded HMI systems requiring real-time graphics, camera interface (DCMI, 54 MB/s), and industrial connectivity (dual CAN, USB OTG HS/FS, 10/100 Ethernet MAC).

For engineers reviewing the STM32F469IGT6 datasheet, STM32F469IGT6 pinout, STM32F469IGT6 application, or STM32F469IGT6 equivalent, key selection criteria include its 176-pin UFBGA package, dual Quad-SPI support, hardware-accelerated 2D graphics via DMA2D, and integrated MIPI D-PHY compliant DSI host - critical for display-rich edge devices.

Technical Context

The STM32F469IGT6 implements an Arm Cortex-M4 core with floating-point unit and DSP extensions, coupled with ST's adaptive real-time accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 180 MHz. Its memory subsystem includes dual-bank Flash supporting read-while-write and flexible external memory controller (FMC) for SDRAM, NOR/NAND, and PSRAM.

Graphics acceleration is handled by the Chrom-ART Accelerator™ (DMA2D), offloading CPU-intensive operations like image blending and format conversion. The MIPI DSI host controller integrates D-PHY physical layer with programmable PLL and regulator, supporting one lane at 500 Mbps for 720p@30 Hz, while the parallel LCD-TFT controller supports RGB888 and ITU-R BT.656 interfaces up to XGA resolution.

Key Specifications

Pinout & Package

FAQ

What is the maximum resolution supported by the LCD-TFT controller?

The LCD-TFT controller (LTDC) supports up to XGA resolution (1024×768) in RGB888 mode with pixel clock up to 60 MHz. It includes programmable timing generators, layer composition (up to 3 layers), and alpha blending - enabling multi-layer GUIs without external graphics memory.

Does STM32F469IGT6 support true MIPI DSI without external PHY?

Yes. The STM32F469IGT6 integrates a fully compliant MIPI D-PHY v1.2 physical layer with dedicated PLL and regulator, supporting one high-speed data lane and clock lane. No external PHY is required for basic 720p@30 Hz operation, though external level-shifting may be needed for certain display modules.

How many independent SPI interfaces does STM32F469IGT6 provide?

The device provides six SPI interfaces (SPI1–SPI6), two of which are multiplexed with full-duplex I2S for audio-class accuracy using internal audio PLL or external clock sources. All six support master/slave modes, configurable frame formats, and DMA-driven transfers up to 45 Mbits/s.

Is the 2 MB Flash memory organized as a single block or split banks?

The 2 MB Flash is organized into two independent banks (Bank 1: 1 MB, Bank 2: 1 MB), enabling true read-while-write operation - critical for safe over-the-air firmware updates where one bank executes active code while the other receives new firmware. Bank swapping is software-controlled via SYSCFG registers.
