The exposed pad needs a via stitch to the ground plane to pull heat out; without it the junction creeps up above 85°C ambient if you push the I/O current. Moisture sensitivity level (MSL) is typical for this class — bake before reflow if the sealed bag has been open longer than the floor-life window. ## Lifecycle and supply position It is current-production from ST, so new designs can commit to it without worrying about a sudden discontinuation. For dual-sourcing resilience, the STM32L0 family has several density and package variants that share the same Cortex-M0+ core and peripheral set, though exact pin compatibility depends on the package footprint.","metaTitle":"STM32L071K8U6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L071K8U6 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 64 KB Flash, 20 KB RAM, 3 KB EEPROM, industrial temp -40°C to 85°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":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"3K x 8","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"23","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":"STM32L071","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/22d621a76748b868dc4a8fc30085ea48.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L071K8U6?","answer":"Within the STM32L0 series, the STM32L071K8U6 shares its pinout and peripheral map with other 32-pin UFQFN variants that use the same base product number STM32L071.
