The LCD controller supports up to XGA resolution with an external frame buffer, though the 256 KB internal RAM limits on-chip buffering to smaller displays — for larger panels you budget an external SDRAM on the FMC bus. The 168 GPIO count in a 216-ball BGA means roughly 48 balls are power, ground, and reserved — plan for a 6-layer or 8-layer PCB to route the BGA escape and the parallel LCD/EMI buses cleanly. It remains a current-production device suitable for new design starts and long-run production BOMs. The STM32F429 base part number spans multiple density and package variants. For BOM resilience, the LQFP176 and LQFP144 siblings share the same core and peripheral set but differ in I/O count and package footprint — a board redesign is required to swap between BGA and QFP. No pin-compatible second source from another manufacturer exists for this exact 216-TFBGA variant.","metaTitle":"STM32F429NIH6U ARM Cortex-M4 MCU, 180 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32F429NIH6U 32-bit MCU with ARM Cortex-M4 core at 180 MHz, 2 MB Flash, 256 KB RAM, Ethernet, CAN, USB OTG, LCD controller.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"180MHz","Series":"STM32F4","Package":"Tray","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"168","Core Processor":"ARM® Cortex®-M4","Package / Case":"216-TFBGA","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F429","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"216-TFBGA (13x13)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.0555","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F429NIH6U/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F429NIH6U have Ethernet?","answer":"Yes, the connectivity set includes an Ethernet MAC controller alongside CANbus, USB OTG, and multiple serial interfaces.

A direct BGA-to-BGA drop-in with identical ball map does not exist — any alternative requires a PCB layout change.
