The Ethernet and CAN interfaces suit industrial gateways or multi-protocol bridges where the MCU runs the protocol stack and application logic on one die. The 176-LQFP (24x24 mm) is a standard JEDEC footprint with 0.5 mm pitch. It is a surface-mount package that reflows with typical lead-free profiles. The 140 I/O pins fan out to four sides, so the PCB layout needs a solid ground plane and adequate decoupling close to each supply pair.","metaTitle":"STM32F429IIT6J STM32F4 ARM Cortex-M4 MCU, 180MHz, 2MB Flash","metaDescription":"STM32F429IIT6J 32-bit MCU with 180MHz ARM Cortex-M4, 2MB Flash, 256KB RAM, 140 I/O, Ethernet, 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":"140","Core Processor":"ARM® Cortex®-M4","Package / Case":"176-LQFP","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":"176-LQFP (24x24)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.5800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F429IIT6J/alternatives.json"},"ai":{"faq":[{"question":"What is STM32F429IIT6J's listed speed?","answer":"The core is rated at 180 MHz, which is the maximum clock frequency for the ARM Cortex-M4 processor in this device."},{"question":"What is the difference between STM32F429IIT6 and STM32F429IIT6J?","answer":"The suffix 'J' typically indicates a specific revision or package variant within the STM32F429 series.
