The 16-channel 12-bit ADC and one 12-bit DAC on-chip mean many mixed-signal control designs — motor drives, digital power supplies, industrial sensors — can skip the external analog front-end. ## Peripheral set and I/O budget for control applications With 51 I/O lines in a 64-LQFP package, this part has enough GPIO to handle a parallel LCD interface, encoder inputs, and a bank of relay drivers simultaneously. On the connectivity side you get CANbus, I²C, SPI, UART/USART, USB, IrDA, and LINbus — enough to talk to a VFD over Modbus RTU, log data to a USB stick, and still have a debug UART free. If you are dual-sourcing a BOM line, the STM32L151CBU6A is a lower-speed (32 MHz), lower-power Cortex-M3 alternative with similar analog peripherals, but it is not a pin-for-pin drop — the LQFP-64 footprint matches, but the peripheral set and core differ.","metaTitle":"STM32F302RET6TR STM32F3 MCU, 72 MHz Cortex-M4, 512KB Flash","metaDescription":"STMicroelectronics STM32F302RET6TR 32-bit ARM Cortex-M4 MCU at 72 MHz, 512KB Flash, 64K x 8 RAM, 16x12b ADC, USB/CAN, -40 to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F3","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F3","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F302","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.6800","priceTiers":[{"qty":1,"price":"$9.68000","currency":"USD"},{"qty":10,"price":"$8.74900","currency":"USD"},{"qty":25,"price":"$8.34200","currency":"USD"},{"qty":100,"price":"$7.24330","currency":"USD"},{"qty":250,"price":"$6.91780","currency":"USD"},{"qty":500,"price":"$6.30740","currency":"USD"},{"qty":1000,"price":"$5.49354","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4c7220c917c6a09ac2dd5a3130dafc01.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F302RET6TR/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F302RET6TR have a USB interface?","answer":"Yes."},{"question":"What is the alternative for STM32F302RET6TR?","answer":"The STM32L151CBU6A is a functional alternative from the same manufacturer, but it runs a Cortex-M3 core at 32 MHz with lower power draw and a different peripheral mix — not a pin-compatible second source.
