For control loops — say, a BLDC commutation routine or a PID update at 10 kHz — the Cortex-M0's 32-bit data path and single-cycle multiply keep the loop tight without needing a DMA-assisted pipeline. Plan the firmware around that ceiling. The 32 KB program memory (32K x 8) is enough for a bootloader, a modest RTOS kernel, and application code for a single-function controller — a thermostat, a fan-speed driver, or a CAN-to-UART gateway. The 4 KB RAM (4K x 8) handles a few hundred bytes of stack, a couple of 256-byte UART buffers, and a small data table. If your application needs over-the-air firmware updates, the Flash must hold both the active image and the staging area, so budget 8–12 KB for the OTA partition. The 13-channel 12-bit ADC can sample up to 13 analog inputs without an external mux, saving board space. ## Package and footprint — 32-LQFP (7x7 mm) The 25 I/O lines include up to 13 ADC inputs and the full set of serial peripherals.","metaTitle":"STM32F031K6T6 ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F031K6T6 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 32 KB Flash, 4 KB RAM, 13-ch 12-bit ADC, -40 to 85°C, 32-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"ARM® Cortex®-M0","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F031","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":"$3.3000","priceTiers":[{"qty":1,"price":"$3.30000","currency":"USD"},{"qty":10,"price":"$2.96700","currency":"USD"},{"qty":25,"price":"$2.80480","currency":"USD"},{"qty":80,"price":"$2.43100","currency":"USD"},{"qty":250,"price":"$2.30628","currency":"USD"},{"qty":500,"price":"$2.06942","currency":"USD"},{"qty":1000,"price":"$1.74530","currency":"USD"},{"qty":2500,"price":"$1.65804","currency":"USD"},{"qty":5000,"price":"$1.59570","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7127f169a82fed95ea2bf9d385a9c5f9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F031K6T6/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F031K6T6 be used as a replacement for STM32F031K4T6?","answer":"Yes, the STM32F031K6T6 is a drop-in pin-compatible upgrade from the STM32F031K4T6, offering 32 KB Flash instead of 16 KB.
