Product details

It is built for applications that need a balance of DSP throughput and peripheral integration — motor drives, industrial PLCs, HMI panels with embedded LCD, and Ethernet-connected gateways.

The 169-UFBGA package measures 7x7 mm — a compact BGA that saves board area but requires at least a 4-layer PCB with microvias for fanout.

Peripherals and data converters

On-chip data conversion includes 24 analog inputs with 12-bit resolution and two 12-bit DACs, enough for multi-channel sensor acquisition or closed-loop analog control. The peripheral set covers brown-out detection, DMA, I²S for audio, LCD controller, PWM timers, and a watchdog — the sort of integrated feature list that saves an external supervisor or codec IC.

Frequently asked questions

What is the difference between STM32F429AIH6 and STM32F429ZIT6?

Both are STM32F429-series MCUs with the same core, speed, and memory. The key difference is the package: the AIH6 comes in a 169-UFBGA (7x7 mm), while the ZIT6 uses a 144-LQFP. The BGA saves board area but requires a more complex PCB stack-up for fanout; the LQFP is easier to route and inspect. Pin compatibility is not guaranteed between the two packages.
