At this speed, Flash wait states need careful configuration — expect to budget at least one wait state above 150 MHz to avoid bus faults on tight branches. ## 2 MB Flash and 256 KB SRAM — memory budget for firmware The 2 MB on-chip Flash is sized for large application code, GUI frame buffers, or OTA staging without external memory. The 256K x 8 SRAM (256 KB) supports moderate data buffers and stack depth; designs needing more than that will use the EBI/EMI to add SDRAM or SRAM externally. ## Peripheral set: Ethernet, LCD, CAN, USB OTG Built-in Ethernet MAC, a TFT LCD controller, CAN 2.0B, and USB OTG FS/HS make this MCU a single-chip solution for industrial gateways, smart displays, and in-vehicle telematics. The LCD controller supports up to XGA resolution with an external display buffer, while the Ethernet MAC works with an external PHY for 10/100 Mbps networking. ST lists the STM32F429NIH6J as obsolete. Buyers should verify date codes and inspect for counterfeit risk when procuring from the spot market.","metaTitle":"STM32F429NIH6J STM32F4 ARM Cortex-M4 MCU, 180 MHz","metaDescription":"STM32F429NIH6J 32-bit ARM Cortex-M4 MCU at 180 MHz with 2 MB Flash, 256K x 8 RAM, Ethernet, LCD, CAN, USB OTG.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","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/STM32F429NIH6J/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STM32F429NIH6J?","answer":"The STM32F429NIH6 (without the 'J' suffix) is pin-compatible and may serve as a drop-in replacement, but verify current lifecycle status separately.
