It packs 29 I/O lines, a 10-channel 12-bit ADC, and serial connectivity including I²C, SPI, and UART/USART into a 36-ball WLCSP package. The supply range from 1.65 V to 3.6 V makes it a fit for single-cell battery applications, and the −40°C to 85°C temperature grade covers most industrial and consumer environments. ## Ultra-low-power architecture and peripherals The 32 MHz core speed is the ceiling for this Cortex-M0+ — it is not a high-throughput part for DSP or heavy protocol stacks. It handles sensor polling, simple control loops, and serial bridge tasks comfortably. The 8KB RAM limits buffer-heavy applications; the 2KB EEPROM is useful for calibration constants or boot parameters that survive a firmware update.","metaTitle":"ST STM32L051T6Y6TR ARM Cortex-M0+ MCU, 32 MHz, 32KB Flash, WLCSP","metaDescription":"STMicroelectronics STM32L051T6Y6TR ultra-low-power 32-bit MCU: 32 MHz ARM Cortex-M0+, 32KB Flash, 8KB RAM, 2KB EEPROM, 29 I/O, 10x12b ADC, I²C/SPI/UART, 1.65–3.6V, −40 to 85°C, 36-","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) Cut Tape (CT)","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K 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":"29","Core Processor":"ARM® Cortex®-M0+","Package / Case":"36-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L051","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"36-WLCSP","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4480b8ddc40b685393082b7ee2561685.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L051T6Y6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact package and pin count for STM32L051T6Y6TR?","answer":"The package is a 36-ball WLCSP (wafer-level chip-scale package), also listed as 36-UFBGA.
