That clock rate is enough for sensor polling, simple control loops, and UART/I²C protocol handling without pushing the flash wait states past one cycle. For battery-powered endpoints that wake briefly and sleep hard, the 32 MHz ceiling keeps dynamic current in check while still offering enough throughput to run a lightweight RTOS or a bare-metal state machine. ## Memory map: 32 KB Flash, 8 KB RAM, 1 KB EEPROM Program memory is 32 KB of Flash, paired with 8 KB of SRAM. That combination fits firmware for a single-sensor node, a small display controller, or a LIN-bus slave. The 1 KB of on-chip EEPROM is a real differentiator — it lets you store calibration constants, configuration profiles, or fault logs without an external serial EEPROM, saving a component and a board trace. ## Package and rework: 28-UFQFPN (4x4 mm) STMicroelectronics lists the STM32L031G6U6 as Active.","metaTitle":"STM32L031G6U6 MCU, ARM Cortex-M0+, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L031G6U6 32-bit ARM Cortex-M0+ MCU at 32 MHz with 32 KB Flash, 8 KB RAM, 1 KB EEPROM, industrial temp range -40°C to 85°C, 28-UFQFPN","metaKeywords":null},"attributes":{"series":"STM32L0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"32MHz","Series":"STM32L0","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"21","Core Processor":"ARM® Cortex®-M0+","Package / Case":"28-UFQFN","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L031","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-UFQFPN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7400","priceTiers":[{"qty":1,"price":"$2.74000","currency":"USD"},{"qty":10,"price":"$2.45800","currency":"USD"},{"qty":25,"price":"$2.32400","currency":"USD"},{"qty":80,"price":"$2.01400","currency":"USD"},{"qty":230,"price":"$1.91074","currency":"USD"},{"qty":440,"price":"$1.71450","currency":"USD"},{"qty":945,"price":"$1.44596","currency":"USD"},{"qty":2940,"price":"$1.37366","currency":"USD"},{"qty":5880,"price":"$1.32202","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3269b6941a20676907c1e15f5d121af6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L031G6U6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32L031G6U6 compatible with the STM32L0 series?","answer":"Yes, it is part of the STM32L0 series and shares the same Cortex-M0+ core, peripheral set, and low-power architecture.
