Product details

It integrates a rich set of peripherals including a TFT LCD controller, Ethernet MAC, CANbus, USB OTG, and multiple I²C/SPI/UART interfaces, making it a fit for human-machine interface (HMI) panels, industrial automation controllers, and networked embedded systems that need both compute throughput and display driving without an external graphics processor.

140 I/Os and the LCD controller — peripheral fit for display-driven designs

With 140 I/Os and an integrated LCD parallel interface (part of the peripheral set), this MCU can drive a TFT panel directly — the Chrom-ART Accelerator and DMA offload pixel manipulation from the core. The 2 MB Flash gives room for a full GUI stack plus application code, while the 256K x 8 SRAM handles frame buffers for moderate-resolution displays without external memory. For designs that need Ethernet connectivity alongside the display, the internal MAC reduces BOM count versus a separate PHY-plus-controller approach.

Package and temperature grade — 176-LQFP, industrial range

Housed in a 176-LQFP (24x24 mm) surface-mount package, the STM32F429IIT6G is a standard fine-pitch QFP that reflows with conventional lead-free profiles.

Frequently asked questions

What is the maximum clock speed of STM32F429IIT6G?

The STM32F429IIT6G runs at 180 MHz maximum core speed, which is the top end for the STM32F4 series and provides enough throughput for real-time control loops, audio processing, and GUI rendering.

Can STM32F429IIT6G be used for LCD driving?

Yes — the STM32F429IIT6G includes an LCD parallel interface and a Chrom-ART Accelerator, allowing direct driving of TFT displays without an external graphics controller. The 2 MB Flash and 256K x 8 SRAM support moderate-resolution frame buffers.
