STMicroelectronics STM32F469VIT6

Overview

STM32F469VIT6 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@30 Hz), and dual Quad-SPI interface - deployed in industrial HMI panels with TFT-LCD and camera-based inspection systems.

For engineers reviewing the STM32F469VIT6 datasheet, STM32F469VIT6 pinout, STM32F469VIT6 application, or STM32F469VIT6 equivalent, key selection criteria include MIPI DSI timing compliance, dual-bank flash read-while-write capability, LCD-TFT controller resolution support (XGA), Ethernet MAC with IEEE 1588v2 hardware timestamping, and 161 I/Os with 5 V tolerance.

Technical Context

The device 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 architecture supporting concurrent code execution and firmware update. Its DMA2D (Chrom-ART Accelerator™) offloads 2D graphics operations including alpha blending and image format conversion.

It features a dedicated MIPI D-PHY physical layer with programmable PLL (125–500 MHz output), supporting up to 720p@30 Hz DSI video streams, and includes a parallel camera interface (DCMI) capable of 54 MB/s throughput with embedded synchronization signals (HSYNC/VSYNC/PCLK).

Key Specifications

Pinout & Package

FAQ

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

The LTDC (LCD-TFT Display Controller) supports up to XGA resolution (1024 × 768) with 24-bit RGB interface and programmable timing parameters. It includes dual-layer composition, alpha blending, and dithering - enabling direct drive of standard industrial TFT panels without external TCON chips.

Does STM32F469VIT6 support hardware JPEG encoding/decoding?

No. The STM32F469VIT6 does not include dedicated JPEG codec hardware. It relies on software libraries (e.g., ARM CMSIS-DSP) or external co-processors for JPEG processing. Its Chrom-ART Accelerator™ handles only 2D graphics primitives (blending, format conversion, memory copy), not compression/decompression algorithms.

Can the MIPI DSI interface operate without an external PHY?

Yes. The STM32F469VIT6 integrates a compliant MIPI D-PHY physical layer with programmable PLL and calibration circuitry - eliminating need for external PHY. It supports 1–4 data lanes at speeds up to 500 Mbps per lane, with automatic skew compensation and LPDT (Low-Power Data Transmission) mode.

Is the 4 KB backup SRAM retained in Standby mode with VBAT?

Yes. When powered by VBAT, the 4 KB backup SRAM remains fully accessible and retains data across Standby mode, along with the 20×32-bit backup registers. This memory is powered independently of main VDD and supports critical state preservation during deep sleep or battery-backed operation.
