Built-in peripherals include a TFT LCD controller, a full-speed Ethernet MAC with dedicated DMA, CANbus, multiple I²C and SPI ports, and two 12-bit DACs plus 24 12-bit ADC channels. This peripheral set targets human-machine interfaces (HMI), industrial gateways, and motor-control panels that need a display and wired networking on a single chip. ## Ethernet on-chip — no external MAC needed The Ethernet controller is a 10/100 MAC with dedicated DMA, which saves an external MAC-PHY bridge and reduces BOM cost for connected designs. The PHY interface is MII/RMII, so the board still needs an external PHY chip and magnetics, but the MAC integration cuts component count and simplifies the PCB layout. ROHS3 compliant. For a production BOM, this means no last-time-buy scheduling and no forced redesign in the near term. The base product number is STM32F429, and the series (STM32F4) has broad ST support with multiple density and package options.","metaTitle":"STM32F429IIT6 STM32 MCU, 180MHz Cortex-M4, 2MB Flash","metaDescription":"STM32F429IIT6 32-bit ARM Cortex-M4 MCU, 180MHz, 2MB Flash, 256KB SRAM, Ethernet, LCD controller, -40 to 85°C.

A lower-power sibling, the STM32L151CBU6A (Cortex-M3 at 32 MHz), shares the ARM ecosystem but has far less Flash (128 KB), no Ethernet, and fewer I/O — it is not a pin-compatible drop-in. For a true second source, look at the STM32F407 series (same package options, similar peripherals but without the LCD controller)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F429IIT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F429IIT6 when reusing this data.
