The 32 KB Flash and 16 KB SRAM suit firmware footprints for field-oriented motor control or sensor-hub processing. ## 64-LQFP — rework-friendly footprint, 51 I/O brought out The 51 GPIOs include remappable pins for the CAN, USB, and multiple SPI/I²C peripherals. The on-chip analog includes a 12-bit ADC with 15 multiplexed channels and a single 12-bit DAC, enough for three-phase current sensing plus a setpoint output. Internal oscillator trims to 1% accuracy, saving an external crystal for UART or CAN at moderate baud rates. The base product number STM32F302 covers multiple Flash and RAM density variants in the same 64-LQFP footprint, so a firmware or memory upgrade (e.g., to the STM32F302R8T6 with 64 KB Flash) is a drop-in swap if the project outgrows the 32 KB limit.","metaTitle":"STM32F302R6T6 STM32F3 ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F302R6T6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 32 KB Flash, 16 KB SRAM, 51 I/O, CAN, USB, 12-bit ADC/DAC, -40 to 85°C.","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":"16K 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 15x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F302","Program Memory Size":"32KB (32K 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":"$6.2400","priceTiers":[{"qty":1,"price":"$6.24000","currency":"USD"},{"qty":10,"price":"$5.60300","currency":"USD"},{"qty":25,"price":"$5.29720","currency":"USD"},{"qty":160,"price":"$4.59088","currency":"USD"},{"qty":320,"price":"$4.35547","currency":"USD"},{"qty":480,"price":"$3.90815","currency":"USD"},{"qty":960,"price":"$3.29603","currency":"USD"},{"qty":2400,"price":"$3.13123","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fef7d39e76d680597279160bb31f782e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F302R6T6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32F302R6T6?","answer":"The core runs at 72 MHz. At that speed the Flash requires one wait state for zero-wait execution; the FPU and single-cycle multiply-accumulate keep the loop tight for control algorithms."},{"question":"Is STM32F302R6T6 the same as STM32F302R8T6?","answer":"No — the R6 variant has 32 KB Flash, while the R8 carries 64 KB Flash. Both share the same 64-LQFP footprint, pinout, and peripheral set, so a firmware migration is a direct board-level swap if you need the extra code space."},{"question":"What is the closest functional second-source for STM32F302R6T6?","answer":"The STM32L151CBU6A is a lower-power ARM Cortex-M3 alternative at 32 MHz with similar connectivity (I²C, SPI, UART, USB) and a 12-bit ADC, but it lacks the FPU and the 72 MHz performance of the Cortex-M4. It is not a pin-compatible drop-in — the package and I/O count differ — so a board redesign is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F302R6T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F302R6T6 when reusing this data.
