Product details

180 MHz Cortex-M4 with 2 MB Flash — display-capable industrial MCU

The STM32F429ZIT6G: 32-bit ARM Cortex-M4 MCU from the STM32F4 series, clocked at 180 MHz with 2 MB Flash and 256 KB RAM. Integrates TFT LCD controller, Ethernet MAC, USB OTG, CANbus, and multiple serial interfaces.

180 MHz core — timing headroom for display pipelines

The 2 MB Flash holds a full graphics library and protocol stack; the 256 KB RAM provides enough frame-buffer space for a QVGA display with double buffering. For designs that need more RAM, the EBI/EMI interface on this package supports external SRAM or SDRAM expansion.

Connectivity set — Ethernet, CAN, USB OTG on one die

Frequently asked questions

What is the closest pin-compatible alternative to STM32F429ZIT6G?

Pin-compatible density variants exist within the STM32F429 line — parts with different Flash/RAM sizes share the same 144-LQFP footprint and peripheral set. The base product number STM32F429 identifies the family; check the STM32F429 reference manual for the specific migration table.

What is STM32F429ZIT6G's listed speed?

The core runs at 180 MHz, which is the maximum clock for this STM32F4 series device. That clock rate supports real-time control loops, graphics rendering, and protocol processing without external accelerators.
