With 32 KB of program memory and 16 KB of SRAM, this MCU fits firmware for a single-axis field-oriented-control (FOC) motor drive or a compact sensor hub aggregating three analog inputs and one CAN bus message queue. If your application needs over-the-air update staging or a larger lookup table, the pin-compatible STM32F303K8T6 doubles the Flash to 64 KB while keeping the same 32-LQFP footprint — a straightforward BOM swap without a board spin. ## Analog density — nine ADC channels and three DACs on a 32-pin package The 9x12-bit ADC array and 3x12-bit DAC converters are the standout feature for a 32-pin MCU. You can simultaneously sample three phase currents in a motor drive while the DAC outputs generate analog reference or offset voltages. The 12-bit resolution is adequate for 0.1% accuracy on a 3.3 V reference — typical for industrial sensor conditioning. Just budget for a clean analog ground plane and separate Vref+ pin decoupling to keep the ADC noise floor below 1 LSB. ## Connectivity — CAN bus and serial interfaces for the factory floor The CAN interface is what sets it apart from the STM32F0 value line; if your design talks to a fieldbus backbone or an automotive ECU, this part saves an external CAN transceiver. The 25 available I/O pins are enough for a handful of sensors, a small keypad, and a status LED bank, but you'll need to mux if you want a parallel LCD or a full 8-bit data bus. ## Package and temperature grade — 32-LQFP at 7x7 mm, industrial range Housed in a 32-LQFP (7x7 mm) package with a 0.8 mm pitch, this MCU is hand-solderable in a rework station and fits on two-layer boards without micro-vias. ROHS3 compliant per the listing, so it passes EU material restrictions without an exemption.","metaTitle":"STM32F303K6T6 ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F303K6T6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 32 KB Flash, 16 KB SRAM, 9x12-bit ADC, 3x12-bit DAC, CAN bus, -40°C 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","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"ARM® Cortex®-M4","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 9x12b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F303","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.0600","priceTiers":[{"qty":1,"price":"$6.06000","currency":"USD"},{"qty":10,"price":"$5.43900","currency":"USD"},{"qty":25,"price":"$5.14160","currency":"USD"},{"qty":80,"price":"$4.45600","currency":"USD"},{"qty":250,"price":"$4.22748","currency":"USD"},{"qty":500,"price":"$3.79330","currency":"USD"},{"qty":1000,"price":"$3.19918","currency":"USD"},{"qty":2500,"price":"$3.03922","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ae49c9e09d1fca7b38ed447004fa24ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F303K6T6/alternatives.json"},"ai":{"faq":[{"question":"What are the differences between STM32F303K6T6 and STM32F303K8T6?","answer":"The STM32F303K8T6 doubles the Flash memory from 32 KB to 64 KB while keeping the same 32-LQFP package, pinout, and peripheral set.
