For a design that needs to bridge a CAN-based sensor network to an Ethernet backbone and serve a web interface over USB, the STM32F479BIT6 handles all three physical layers without external controllers. The 161 general-purpose I/O lines, mapped across the 208-LQFP package, provide enough pins to drive a parallel TFT LCD (via the built-in LCD controller), read a 24-channel 12-bit ADC, and still leave room for a memory-mapped EBI/EMI bus to external SRAM or NOR Flash. ## 208-LQFP footprint — board area and routing That is a large, hand-solderable QFP — no BGA reflow required, but the board area commitment is about 784 mm². The 161 I/O signals will need at least a 4-layer PCB to route cleanly, especially when the Ethernet RMII and USB differential pairs are in the mix.","metaTitle":"STM32F479BIT6 STM32F4 ARM Cortex-M4 MCU, 180MHz, 2MB Flash","metaDescription":"STM32F479BIT6 32-bit ARM Cortex-M4 MCU at 180MHz, 2MB Flash, 384KB RAM, 161 I/O, Ethernet MAC, USB OTG, CAN, 24x12b ADC, -40 to 85°C, 208-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"180MHz","title":"STM32F479BIT6","Series":"STM32F4","Package":"Tray","RAM Size":"384K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, SAI, SDIO, SPI, UART/USART, USB, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"161","Core Processor":"ARM® Cortex®-M4","Package / Case":"208-LQFP","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F479","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"208-LQFP (28x28)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.2900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa28d2d3349ab91a6e3e1b8a8b694afe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F479BIT6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum operating frequency of STM32F479BIT6?","answer":"The core runs at 180 MHz.
