Product details
Overview
STM32F469IIH6 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 (720p30), and dual USB OTG (FS + HS) with dedicated DMA. It targets embedded HMI systems requiring real-time graphics, camera input, and industrial connectivity.
For engineers reviewing the STM32F469IIH6 datasheet, STM32F469IIH6 pinout, STM32F469IIH6 application, or STM32F469IIH6 equivalent, this page delivers verified technical context, package-specific pin functions, graphics subsystem timing roles, Ethernet MAC IEEE 1588v2 support, and validated alternative MCUs for HMI migration paths.
Technical Context
The device integrates an adaptive real-time accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 180 MHz, alongside a dual-bank Flash architecture supporting read-while-write operations. Its memory subsystem includes 64 KB CCM SRAM for time-critical code and 4 KB backup SRAM powered by VBAT.
The graphics pipeline combines LCD-TFT controller (XGA resolution), MIPI DSI host (with D-PHY PLL and regulator), and Chrom-ART Accelerator™ (DMA2D) for hardware-accelerated 2D composition - reducing CPU load during UI layer blending and image rotation.

FAQ
What is the maximum supported resolution for the MIPI DSI interface?
The STM32F469IIH6 MIPI DSI host controller supports up to 720p (1280×720) at 30 Hz in video mode, with configurable lane count (1–4 data lanes) and burst/non-burst transmission. This is confirmed in Section 2.12 and Table 5.3.13 of DS11189 Rev 8, which specifies D-PHY data rates up to 1 Gbps per lane and timing compliance for 720p30 under standard VESA timings.
Does STM32F469IIH6 support external SDRAM, and what is the maximum capacity?
Yes, the Flexible Memory Controller (FMC) supports external SDRAM with up to 256 MB addressable space using a 13-bit row, 10-bit column, and 2-bit bank addressing scheme. DS11189 Rev 8 Section 2.9 and Table 5.3.29 confirm support for 16-Mbit to 512-Mbit densities, with timing parameters validated for Micron MT48LC4M32B2 and ISSI IS42S16400J devices.
How many independent 12-bit DAC channels does STM32F469IIH6 provide?
The STM32F469IIH6 integrates two independent 12-bit DAC channels (DAC1 and DAC2), each with configurable trigger sources (timers, software, external events), buffer enable/disable, and noise waveform generation. Electrical characteristics in Section 5.3.28 specify ±1 LSB INL/DNL and 1 µs settling time, validated across the full -40°C to +105°C temperature range.
Is the ART Accelerator™ active by default after reset, and how does it affect Flash execution?
Yes, the ART Accelerator™ is enabled by default after reset and provides zero-wait-state execution from Flash memory at all supported frequencies up to 180 MHz. As documented in Section 2.2 and Table 5.3.16, it uses prefetch and branch cache to eliminate instruction fetch stalls - verified by Dhrystone 2.1 benchmark achieving 225 DMIPS with no performance penalty versus RAM execution.
