Communication interfaces cover I²C, SPI, UART/USART, LINbus, and IrDA — enough to talk to most sensors, displays, and serial peripherals without external protocol chips. The 27 I/O pins in the 32-UFQFN package give reasonable headroom for a compact sensor node or control board. ## Package and layout — the 5x5 mm exposed-pad UFQFN Housed in a 32-UFQFN with exposed pad (supplier package 32-UFQFPN, 5x5 mm), this is a surface-mount part that needs a thermal via stitch under the pad for heat dissipation if you push continuous current. The small footprint saves board space but demands careful decoupling — keep the 100 nF cap close to each supply pin pair. No lab bench needed for rework if you have a hot-air station and a steady hand. ## Sourcing reality — active and available through independent distribution No LTB risk, no last-time-buy math needed for new designs.","metaTitle":"STM32L031K6U7 ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L031K6U7 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 32 KB Flash, 8 KB RAM, 1 KB EEPROM, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"27","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-UFQFN Exposed Pad","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 ~ 105°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7096","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9da9efc4233dfdd482528b8b281fc32a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L031K6U7 have an internal oscillator?","answer":"Yes, the STM32L031K6U7 has an internal oscillator, so it can run without an external crystal for basic operation.
