The EBI/EMI bus can gluelessly connect to external SRAM, NOR Flash, or NAND Flash. For a system architect, this means a single STM32F429IIH6TR can serve as the main application processor handling Ethernet connectivity, CAN bus for industrial fieldbus, and a local display — no separate network coprocessor or graphics controller needed. The 140 general-purpose I/O lines in the 176+25 UFBGA package give plenty of pins for parallel buses and sensor arrays. ## Package and layout — 176+25 UFBGA (10x10 mm) For a BOM manager, this means no near-term last-time-buy risk and continued manufacturer support for new designs.","metaTitle":"STM32F429IIH6TR STM32F4 ARM Cortex-M4 MCU, 180 MHz","metaDescription":"STM32F429IIH6TR 32-bit ARM Cortex-M4 MCU at 180 MHz with 2 MB Flash, 256K x 8 RAM, Ethernet, LCD controller, CAN, USB OTG.","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":"Tape & Reel (TR)","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":"140","Core Processor":"ARM® Cortex®-M4","Package / Case":"201-UFBGA","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":"176+25UFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.8085","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F429IIH6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F429IIH6TR and STM32F429IIH6?","answer":"The STM32F429IIH6TR is the Tape & Reel (TR) packaged variant of the STM32F429IIH6. The die, the 176+25 UFBGA package, the 180 MHz speed, 2 MB Flash, and all peripherals are identical. The TR suffix only changes the shipping medium — Tape & Reel for pick-and-place machines versus tray or tube for the base part number. If your assembly line feeds from reels, order the TR variant; if you hand-place prototypes or use a tray feeder, the base STM32F429IIH6 works the same."},{"question":"Does STM32F429IIH6TR have Ethernet and LCD support?","answer":"Yes. The STM32F429IIH6TR includes an Ethernet MAC peripheral and an integrated LCD controller with DMA support, as listed in the connectivity and peripherals set.
