The 10-channel 12-bit ADC handles analog sensor inputs, while the I²C, SPI, and UART interfaces connect to common peripherals like temperature sensors, displays, and radio modules. ## Memory and peripheral fit for small-footprint firmware The 16 KB Flash and 2 KB SRAM are modest — expect to fit a lightweight RTOS or a bare-metal control loop with a few hundred lines of application code. The 512-byte EEPROM is handy for storing configuration parameters or calibration data without wearing the Flash. The 10-channel ADC at 12-bit resolution is adequate for most analog sensor interfaces. ## Package and hand-soldering considerations The 32-UFQFPN package has a 0.5 mm pitch and an exposed thermal pad underneath. ## How it compares to the STM32L151CBU6A The STM32L151CBU6A uses a Cortex-M3 core at 32 MHz and offers 37 I/O, 16 ADC channels, two DAC channels, and USB connectivity.","metaTitle":"STM32L011K4U6TR ARM Cortex-M0+ MCU, 32 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32L011K4U6TR 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 16 KB Flash, 2 KB SRAM, 512 B EEPROM, 10-ch 12-bit ADC, I²C/SPI/UART, -40°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":"Tape & Reel (TR) Cut Tape (CT)","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":100,"price":"$2.03550","currency":"USD"},{"qty":250,"price":"$1.93108","currency":"USD"},{"qty":500,"price":"$1.73276","currency":"USD"},{"qty":1000,"price":"$1.46137","currency":"USD"},{"qty":3000,"price":"$1.38830","currency":"USD"},{"qty":6000,"price":"$1.33611","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/186ae0e234bc3e91c5436123bd03d6e8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L011K4U6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L011K4U6TR and STM32L011K4U6?","answer":"The 'TR' suffix indicates Tape & Reel packaging, while the base part number without 'TR' typically ships in Tray or Tube.
