STMicroelectronics STM32F469IGH6TR

Overview

STM32F469IGH6TR from STMicroelectronics is a high-performance Arm® Cortex®-M4 MCU with FPU, 180 MHz max clock, 2 MB Flash, 384+4 KB SRAM, integrated Chrom-ART Accelerator™ for GUI rendering, MIPI DSI host controller (720p@30Hz), and dual USB OTG (FS/HS) + 10/100 Ethernet MAC. It targets embedded HMI systems requiring real-time graphics, camera interface (54 MB/s DCMI), and industrial connectivity.

For engineers reviewing the STM32F469IGH6TR datasheet, STM32F469IGH6TR pinout, STM32F469IGH6TR application, or STM32F469IGH6TR equivalent, key selection criteria include MIPI DSI host capability, dual Quad-SPI support, LCD-TFT controller with XGA resolution, hardware-accelerated 2D graphics (DMA2D), and IEEE 1588v2 Ethernet timing precision.

Technical Context

This MCU integrates an adaptive real-time accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 180 MHz, alongside a memory protection unit (MPU) and dual-bank Flash supporting read-while-write. Its graphics subsystem combines a dedicated LCD-TFT controller (up to XGA), MIPI DSI host (with D-PHY PLL and regulator), and Chrom-ART Accelerator™ (DMA2D) for hardware-accelerated bitmap blending and format conversion.

The connectivity stack includes two CAN 2.0B controllers, six SPIs (45 Mbps), four USARTs, SDIO, USB OTG HS/FS with dedicated DMA and dual PHYs, and a 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping - all routed through a multi-AHB bus matrix with configurable priority arbitration.

Key Specifications

Pinout & Package

STM32F469IGH6TR uses a UFBGA176 (10 × 10 mm, 0.8 mm pitch) package with 161 I/Os - up to 157 fast I/Os (90 MHz), 159 5 V-tolerant pins, and dedicated balls for MIPI DSI lanes (CLKP/N, DAT0P/N–DAT3P/N), DCMI (D0–D13, HSYNC, VSYNC, PIXCLK), FMC, and dual Quad-SPI.

FAQ

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

The LTDC (LCD-TFT Display Controller) supports up to XGA resolution (1024×768) with 24-bit RGB output. It includes programmable horizontal/vertical synchronization, pixel clock generation, and layer composition with alpha blending - verified in DS11189 Rev 8 Section 2.11 and Table 5.3.32.

Does STM32F469IGH6TR support MIPI DSI with command mode?

Yes - the DSI Host controller supports both video mode (burst/non-burst) and command mode (DSI Command Mode), enabling direct register access to display drivers via DCS commands. This is confirmed in Section 2.12 and electrical specs Table 5.3.13–5.3.15 of the datasheet.

How many external memory interfaces does this MCU provide?

It provides one Flexible Memory Controller (FMC) supporting SRAM, PSRAM, NOR/NAND flash, and SDRAM/LPSDR, plus two independent Quad-SPI interfaces - each capable of memory-mapped execution. All are electrically and functionally distinct, per Sections 2.9 and 2.10 of DS11189 Rev 8.

Is the USB OTG HS interface compatible with ULPI PHYs?

Yes - the USB OTG HS peripheral includes a dedicated ULPI (UTMI+ Low Pin Interface) port compliant with ULPI v1.1, allowing connection to external high-speed PHYs. This is documented in Section 2.36 and electrical characteristics Table 5.3.23 of the official datasheet.
