The 32-UFQFPN package with exposed pad (5x5 mm) keeps the board footprint small, and the 25 I/O lines plus a 10-channel 12-bit ADC give enough headroom for sensor-node or IoT-edge designs that don't need a full 64-pin part. ## Peripherals and connectivity — what is on-chip Connectivity covers I2C, IrDA, LINbus, SPI, and UART/USART, which covers most low-speed sensor and actuator interfaces. The data converter section is a 10-channel 12-bit ADC, adequate for reading analog sensors like thermistors, potentiometers, or current-sense resistors. ## Tape & Reel — what the TR suffix means for the kitting line The part ships in a reel suitable for volume production; if your CM needs tube or tray, make sure the BOM calls out the non-TR variant (STM32L041K6U6).","metaTitle":"STM32L041K6U6TR ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L041K6U6TR 32-bit ARM Cortex-M0+ MCU at 32 MHz, 32 KB Flash, 8 KB SRAM, 1 KB EEPROM, 25 I/O, 10x12b ADC, -40 to 85°C, 32-UFQFPN.","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":"Tape & Reel (TR)","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":"25","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":"STM32L041","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7024","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/753c77324476fdd7794c6f26274fa242.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32L041K6U6TR?","answer":"The maximum core clock speed is 32 MHz, driven by an ARM Cortex-M0+ core.
