STMicroelectronics STM32F469AGH6TR

Overview

STM32F469AGH6TR from STMicroelectronics is a high-performance Arm® Cortex®-M4 MCU with FPU and ART Accelerator™, operating up to 180 MHz (225 DMIPS), featuring 1 MB flash, 384 KB SRAM + 4 KB backup SRAM, integrated Chrom-ART Accelerator™ for GUI rendering, MIPI DSI host controller (720p@30 Hz), and dual USB OTG (FS/HS) with dedicated DMA. It targets embedded HMI systems requiring real-time graphics, camera interface, and industrial connectivity.

For engineers reviewing the STM32F469AGH6TR datasheet, STM32F469AGH6TR pinout, STM32F469AGH6TR application, or STM32F469AGH6TR equivalent, key selection criteria include MIPI DSI support, dual Quad-SPI capability, Ethernet MAC with IEEE 1588v2 hardware timestamping, LCD-TFT controller up to XGA resolution, and 161 I/Os with 159 5 V-tolerant pins - all critical for display-rich industrial control and medical HMI designs.

Technical Context

This MCU integrates a dual-bank flash architecture enabling true read-while-write operation, a flexible memory controller (FMC) supporting SDRAM, PSRAM, NOR/NAND, and dual Quad-SPI interfaces for external XIP or code/data expansion. Its clock system includes three PLLs (main, audio, SAI) plus dedicated MIPI D-PHY PLL and regulator for DSI compliance.

The peripheral set is optimized for multimedia HMI: parallel DCMI (54 MB/s), SAI and I2S audio interfaces, 3× 12-bit ADCs (7.2 MSPS triple interleaved), 2× DACs, and advanced timers with quadrature encoder input - all synchronized via multi-AHB bus matrix and 16-stream DMA with FIFOs and burst support.

Key Specifications

Pinout & Package

STM32F469AGH6TR uses a UFBGA176 (10 × 10 mm, 0.8 mm pitch) package with 161 user I/Os. Pin functions are defined across five voltage domains (VDD/VSS, VDDA/VSSA, VBAT, VCAP1/VCAP2, USB/DSI power rails), supporting simultaneous 5 V-tolerant I/Os (159 pins), analog inputs, and high-speed differential signaling for MIPI DSI and USB HS.

FAQ

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

The STM32F469AGH6TR's LTDC (LCD-TFT Display Controller) supports up to XGA resolution (1024 × 768 pixels) with 24-bit color depth and programmable timing parameters. It includes dual-layer composition, alpha blending, and dithering - enabling smooth transitions and efficient memory bandwidth usage without external frame buffer RAM in many configurations.

Does STM32F469AGH6TR support MIPI DSI without external PHY?

Yes - it integrates a full MIPI D-PHY v1.2 compliant transmitter with dedicated PLL and regulator, supporting one clock lane and up to two data lanes (DP0/DM0 and DP1/DM1). No external PHY is required for standard DSI display connections, though level-shifting may be needed for non-1.2 V panels.

How does the ART Accelerator™ improve real-time determinism?

The ART Accelerator™ implements prefetch, branch prediction, and cache-like instruction buffering to eliminate flash wait states at 180 MHz. This ensures consistent instruction fetch timing - critical for hard real-time tasks like motor control loops or audio sample processing - without requiring code relocation to SRAM or external cache components.

Can the 4 KB backup SRAM retain data during VBAT-only operation?

Yes - when VBAT is supplied and the backup domain is enabled, the optional 4 KB backup SRAM remains powered and retains data across main power loss, reset, or standby modes. It is accessible only via the PWR and BKP registers and requires explicit enablement in software before entering low-power states.
