It carries 512 KB of Flash and 256 KB of SRAM, plus a flexible memory controller for external SDRAM or NOR/NAND Flash expansion. The part integrates a TFT LCD controller, a hardware cryptographic accelerator, and a full-speed USB OTG PHY — making it a fit for human-machine interface panels, industrial gateways, and mid-range embedded control where display output and network connectivity share the same chip. ## Memory and peripheral budget for display-centric designs The 512 KB Flash and 256 KB SRAM on this MCU support moderately sized firmware stacks — enough for a FreeRTOS application with a TCP/IP stack, a graphics library frame buffer, and a CANopen stack. Designs that need more than 256 KB of working RAM for display buffers or data logging will use the FMC to add external SDRAM. The 24-channel 12-bit ADC and dual 12-bit DAC cover analog front-end requirements without an external converter. The STM32F429ZET6 is recorded as end-of-life (EOL) in the lifecycle stage.","metaTitle":"STMicroelectronics STM32F429ZET6 ARM Cortex-M4 MCU, 180MHz","metaDescription":"STM32F429ZET6 32-bit MCU with 180MHz Cortex-M4 core, 512KB Flash, 256KB RAM, Ethernet, CAN, USB OTG, 114 I/O, 144-LQFP, -40 to 85°C.
