For a board that needs both a display interface and wired networking, this part consolidates what would otherwise require a companion chip. That means no last-time-buy window to track, no end-of-life notice to schedule around.","metaTitle":"STM32F437IIT6 MCU, ARM Cortex-M4 180MHz, 2MB Flash, 176-LQFP","metaDescription":"STM32F437IIT6 32-bit ARM Cortex-M4 MCU from STMicroelectronics, 180MHz core, 2MB Flash, 256K x 8 RAM, 140 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"140","Core Processor":"ARM® Cortex®-M4","Package / Case":"176-LQFP","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F437","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":"$19.6200","priceTiers":[{"qty":1,"price":"$19.62000","currency":"USD"},{"qty":10,"price":"$18.03500","currency":"USD"},{"qty":40,"price":"$17.28775","currency":"USD"},{"qty":80,"price":"$15.23188","currency":"USD"},{"qty":240,"price":"$14.48433","currency":"USD"},{"qty":440,"price":"$13.54984","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7ccff475f92d57ddcb2c7509216e5655.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F437IIT6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32F437IIT6?","answer":"The STM32F437IIT6 is rated for a 180 MHz core clock.
