It carries 2 MB of Flash and 256 KB of SRAM on-chip, with 168 general-purpose I/Os brought out to a 216-ball TFBGA package measuring 13x13 mm. ## Memory and peripheral set for system-level integration The 2 MB program Flash is organised as 2M x 8 bits, giving enough room for a full RTOS, TCP/IP stack, graphics library, and application code without external memory for many designs. The 256 KB SRAM supports double-buffered LCD frame updates and DMA transfers. On the peripheral side, the device integrates Ethernet MAC, CAN 2.0B, USB OTG HS/FS, multiple SPI, I²C, UART, and I²S audio interfaces, plus an external memory interface (EBI/EMI) for SDRAM or NOR/NAND Flash expansion. The LCD controller with its own DMA channel can drive a parallel RGB display directly. The base product number STM32F429 covers a range of Flash and RAM density options in the same package footprint, so if a future project needs a different memory tier, the migration stays within the same PCB layout. ## 216-ball TFBGA — what the package means for assembly The package requires a multi-layer PCB with microvia capability for fanout, and an X-ray inspection step after reflow. The 'E' suffix in the ordering code denotes the tray-pack variant — if your pick-and-place line feeds from tape and reel, verify the packing option before ordering. ## Data converters and analogue integration The device includes three 12-bit ADCs with up to 24 multiplexed channels, plus two 12-bit DACs. For sensor-heavy designs, this reduces the external analogue front-end count. The brown-out detect and POR circuits are built in, simplifying the power supply sequencing.","metaTitle":"STM32F429NIH6E STM32F4 ARM Cortex-M4 MCU, 180MHz, 2MB Flash","metaDescription":"STMicroelectronics STM32F429NIH6E 32-bit ARM Cortex-M4 MCU at 180MHz with 2MB Flash, 256KB RAM, 168 I/O, 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":"$0.5800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F429NIH6E/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F429NIH6E and STM32F429NIH6?","answer":"The 'E' suffix in STM32F429NIH6E indicates the tray packing option.
