It comfortably fits a bootloader plus a modest application — think a temperature logger, a simple Modbus RTU slave, or a Hall-effect sensor interface. If your firmware image needs more headroom, the STM32L0 family offers pin-compatible parts with up to 64 KB Flash (same package and pinout), so a density upgrade is a board-spin, not a respin.","metaTitle":"STM32L011K4U6 ARM Cortex-M0+ MCU, 32 MHz, 16 KB Flash","metaDescription":"STM32L011K4U6 32-bit MCU from STMicroelectronics, ARM Cortex-M0+ core at 32 MHz, 16 KB Flash, 2 KB SRAM, 512 B EEPROM, 1.65-3.6 V supply, -40 to 85°C.","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":"2K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"512 x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","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":"STM32L011","Program Memory Size":"16KB (16K 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":"$2.7700","priceTiers":[{"qty":1,"price":"$2.77000","currency":"USD"},{"qty":10,"price":"$2.48400","currency":"USD"},{"qty":25,"price":"$2.34880","currency":"USD"},{"qty":80,"price":"$2.03550","currency":"USD"},{"qty":230,"price":"$1.93109","currency":"USD"},{"qty":440,"price":"$1.73277","currency":"USD"},{"qty":945,"price":"$1.46137","currency":"USD"},{"qty":2940,"price":"$1.38830","currency":"USD"},{"qty":5880,"price":"$1.33611","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/186ae0e234bc3e91c5436123bd03d6e8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L011K4U6/alternatives.json"},"ai":{"faq":[{"question":"Can STM32L011K4U6 be programmed using ST-Link?","answer":"Yes, the STM32L0 family uses the standard SWD debug interface, which is supported by ST-Link/V2 and ST-Link/V3 programmers.
