The 32 KB Flash and 16 KB SRAM are the fit check: if your firmware binary exceeds 32 KB, you step up to the 64 KB or 128 KB Flash variants in the same STM32F302 family. The 32-UFQFPN (5×5 mm) with exposed pad is a compact, low-profile package suited for space-constrained PCBs. Under a hot-air station, preheat the board to 120°C before lifting; the small QFN body heats quickly, and the exposed pad wicks solder away from the perimeter joints if the profile is too aggressive.","metaTitle":"STM32F302K6U6 STM32F3 ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash","metaDescription":"STM32F302K6U6 32-bit ARM Cortex-M4 MCU from STMicroelectronics. 72 MHz core, 32 KB Flash, 16 KB SRAM, CAN/USB/I2C/SPI, -40°C to 85°C, 32-UFQFPN.","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":"24","Core Processor":"ARM® Cortex®-M4","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x12b; 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":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3100","priceTiers":[{"qty":1,"price":"$5.31000","currency":"USD"},{"qty":10,"price":"$4.77300","currency":"USD"},{"qty":25,"price":"$4.51240","currency":"USD"},{"qty":80,"price":"$3.91063","currency":"USD"},{"qty":230,"price":"$3.71009","currency":"USD"},{"qty":490,"price":"$3.32906","currency":"USD"},{"qty":980,"price":"$2.80764","currency":"USD"},{"qty":2450,"price":"$2.66726","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fef7d39e76d680597279160bb31f782e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F302K6U6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to STM32F302K6U6?","answer":"The STM32L151CBU6A is a functional alternative from the STM32L1 series, but it runs a Cortex-M3 core at 32 MHz (vs 72 MHz Cortex-M4 with FPU), has 37 I/Os, and operates down to 1.8 V.
