The 168 GPIOs and rich peripheral set — Ethernet MAC, dual CAN, USB OTG, LCD controller, and a flexible external bus interface (EBI/EMI) — target it squarely at industrial HMI panels, PLCs, motor drives, and communication gateways where a single chip handles both control and connectivity. ## 1 MB Flash and 256 KB SRAM — firmware footprint and buffer budget The 1 MB program Flash (1M x 8) supports a substantial application image — a bootloader, a FreeRTOS or similar kernel, a graphics stack, and a protocol stack can all fit without external Flash. The 256 KB SRAM (256K x 8) provides generous headroom for DMA descriptors, LCD frame buffers, and multiple communication buffers; it reduces the need for external SRAM or SDRAM in many designs. Both memory sizes are typical for the high-end STM32F4 line, and the Flash is rated for 10,000 erase/write cycles per sector — adequate for field-update OTA staging with wear leveling in the firmware layer. ## Connectivity and peripherals — Ethernet, CAN, USB OTG, LCD This MCU integrates an Ethernet MAC with dedicated DMA (MII/RMII), two CAN 2.0B interfaces, USB OTG FS and HS, and multiple SPI, I²C, UART/USART, and I²S serial interfaces. The external bus interface (EBI/EMI) supports SRAM, NOR/NAND Flash, and SDRAM, enabling expansion beyond the on-chip memory. The LCD controller (TFT, up to 24-bit parallel RGB) drives displays directly, and the 12-bit ADCs (24 channels) and two 12-bit DACs handle analog sensor inputs and outputs. The brown-out detect, POR, and programmable voltage detector simplify power sequencing and supervision. ## Package and temperature grade — 208-LQFP, -40 to 85 °C Housed in a 208-pin LQFP (28x28 mm body, 0.5 mm pitch), the STM32F429BGT6 is a surface-mount device that routes well on a four-layer or six-layer PCB. The part is ROHS3 compliant.","metaTitle":"STM32F429BGT6 ARM Cortex-M4 MCU, 180 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32F429BGT6 32-bit MCU with 180 MHz Cortex-M4 FPU, 1 MB Flash, 256 KB SRAM, Ethernet, CAN, USB OTG.
