STMicroelectronics STM32F469NEH6

Overview

STM32F469NEH6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 MCU with FPU, 180 MHz max clock, 512 KB Flash, 384+4 KB SRAM (including 64 KB CCM), Chrom-ART Accelerator™ for GUI rendering, MIPI DSI host controller supporting 720p@30 Hz, and dual CAN 2.0B interfaces - deployed in industrial HMI panels with TFT-LCD and touch interface.

For engineers reviewing the STM32F469NEH6 datasheet, STM32F469NEH6 pinout, STM32F469NEH6 application, or STM32F469NEH6 equivalent, key selection factors include MIPI DSI timing compliance, LCD-TFT controller resolution support (up to XGA), dual Quad-SPI for external flash expansion, Ethernet MAC with IEEE 1588v2 hardware timestamping, and 159 5 V-tolerant I/Os for mixed-voltage system interfacing.

Technical Context

The STM32F469NEH6 integrates an adaptive real-time memory accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 180 MHz, alongside a dedicated DMA2D engine for 2D graphics composition without CPU load. Its dual-bank Flash architecture supports true read-while-write operation critical for firmware over-the-air updates.

It features a dual-clock domain design: one PLL for system core and peripherals (up to 180 MHz), plus separate audio and LCD PLLs (PLLI2S/PLLSAI) for jitter-free audio streaming and precise pixel clock generation. The MIPI D-PHY physical layer complies with D-PHY v1.2 spec, supporting HS mode up to 1 Gbps per lane for display data transmission.

Key Specifications

Pinout & Package

FAQ

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

The STM32F469NEH6's LTDC (LCD-TFT Display Controller) supports up to XGA resolution (1024 × 768) at 60 Hz using the parallel RGB interface. It provides programmable timing generators, up to 8 layers with alpha blending, and hardware dithering - verified in ST Application Note AN4861 and confirmed by register-level configuration in RM0386 Reference Manual Section 38.

Does STM32F469NEH6 support MIPI DSI in both High-Speed and Low-Power modes?

Yes - the MIPI DSI host controller fully supports both High-Speed (HS) and Low-Power (LP) modes per MIPI D-PHY v1.2 specification. It implements automatic LP-to-HS and HS-to-LP transitions, lane shutdown, and escape mode entry/exit - validated in ST's UM1905 User Manual and electrical test reports for DS11189 Rev 8.

How many external memory interfaces does STM32F469NEH6 provide, and what types are supported?

The STM32F469NEH6 integrates two distinct external memory interfaces: (1) Flexible Memory Controller (FMC) supporting SRAM, PSRAM, NOR/NAND flash, and SDRAM up to 32-bit data bus; and (2) dual Quad-SPI interfaces supporting memory-mapped and indirect modes for serial NOR/NAND flash - all documented in Sections 2.9 and 2.10 of DS11189 Rev 8.

Is the ART Accelerator™ enabled by default after reset, and can it be disabled?

Yes - the ART Accelerator™ is enabled by default after reset and remains active unless explicitly disabled via SYSCFG->MEMRMP register (bit 8). Disabling it increases Flash wait states at >30 MHz, reducing performance but allowing precise cycle-counting for timing-critical routines - behavior confirmed in RM0386 Section 3.3.3 and DS11189 Section 2.2.
