The 2 MB Flash gives room for a full GUI stack plus application code, while the 256K x 8 SRAM handles frame buffers for moderate-resolution displays without external memory. For designs that need Ethernet connectivity alongside the display, the internal MAC reduces BOM count versus a separate PHY-plus-controller approach. ## Package and temperature grade — 176-LQFP, industrial range Housed in a 176-LQFP (24x24 mm) surface-mount package, the STM32F429IIT6G is a standard fine-pitch QFP that reflows with conventional lead-free profiles.","metaTitle":"STM32F429IIT6G STM32F4 MCU, ARM Cortex-M4, 180MHz, 2MB Flash","metaDescription":"STMicroelectronics STM32F429IIT6G 32-bit ARM Cortex-M4 MCU, 180MHz, 2MB Flash, 256K x 8 RAM, 176-LQFP.
