180 MHz Cortex-M4 with on-chip Ethernet and LCD controller
The STMicroelectronics STM32F429ZIT6 is a 32-bit ARM Cortex-M4 single-core MCU clocked at 180 MHz, with 2 MB of Flash and 256 KB of SRAM. It integrates a TFT LCD controller, Ethernet MAC, two CAN interfaces, USB OTG, and 114 general-purpose I/Os in a 144-LQFP package. This part targets HMI panels, industrial gateways, and motor-control drives that need a single-chip CPU with display and network capability.
The 2 MB Flash is sized for a full GUI stack with embedded Ethernet and CANopen firmware; the 256 KB SRAM handles frame buffers and real-time data queues without external memory. On-chip Ethernet eliminates a separate MAC chip, and the two CAN controllers cover dual-bus machine control. The 114 I/Os provide headroom for parallel LCD data buses and sensor inputs without a port expander.
