The dual DAC handles setpoint generation or offset trimming without extra analog ICs, consolidating the BOM. ## Connectivity and peripherals for mixed-signal control The peripheral set includes CANbus, I²C, SPI, UART/USART, USB, and I²S for audio or serial data links. DMA, POR, PWM timers, and a watchdog timer are on-chip. With 51 GPIOs in the 64-LQFP, most designs have enough I/O for local sensors, HMI buttons, and status LEDs without a port expander. Surface-mount assembly in the 64-LQFP is standard reflow; no special handling beyond MSL 3 bake requirements. ST lists the STM32F303RET6 as Active (current production). The base product number is STM32F303, meaning pin-compatible density variants (different Flash/RAM sizes) exist in the same 64-LQFP footprint for scaling production without a board spin.","metaTitle":"STM32F303RET6 MCU, ARM Cortex-M4, 72 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F303RET6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 512 KB Flash, 80 KB SRAM, 22x12-bit ADC, 2x12-bit DAC, industrial temp -40°C to","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":"Tray","RAM Size":"80K 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 22x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F303","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":"$10.4100","priceTiers":[{"qty":1,"price":"$10.41000","currency":"USD"},{"qty":10,"price":"$9.40700","currency":"USD"},{"qty":25,"price":"$8.96960","currency":"USD"},{"qty":160,"price":"$7.78825","currency":"USD"},{"qty":320,"price":"$7.43822","currency":"USD"},{"qty":480,"price":"$6.78190","currency":"USD"},{"qty":960,"price":"$5.90682","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c1aa05dbd335dffd091de829325705a6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F303RET6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32F303RET6?","answer":"The STM32F303RET6 is rated for a 72 MHz core clock.
