Product details

It is designed for applications that need a balance of processing throughput, peripheral integration, and memory headroom — think industrial HMI panels, motor-drive control, multi-protocol gateways, and medical monitoring terminals.

Peripheral set: LCD controller, Ethernet, and DMA

A distinguishing feature of this part is the integrated LCD controller, which drives a display panel without a separate graphics processor. The DMA engine offloads data transfers to the LCD, Ethernet, and external memory, keeping the Cortex-M4 free for application code.

There is no official pin-compatible replacement from ST — the active status means you can continue to design it in without near-term obsolescence risk.

Frequently asked questions

What is the difference between STM32F429NIH6 and STM32F429ZIT6?

Both are STM32F429 series MCUs with the same Cortex-M4 core at 180 MHz, 2 MB Flash, and 256K x 8 RAM. The key difference is the package: STM32F429NIH6 is a 216-ball TFBGA (13x13 mm), while STM32F429ZIT6 is a 144-pin LQFP. The BGA variant offers more I/O (168 vs 144) and a smaller footprint, but requires X-ray inspection for assembly.
