The 1.65 V minimum supply voltage lets it run directly from two alkaline cells or a single Li-ion through most of its discharge curve, saving a boost converter. Typical applications include battery-powered sensors, IoT edge nodes, portable medical devices, and industrial control panels where every microamp counts. The 48-LQFP package with 37 I/O gives enough GPIO for a keypad, a small display, and a few serial peripherals without needing a port expander. ## Peripherals and connectivity The 10-channel 12-bit ADC handles analog inputs like thermistors or potentiometers without an external converter.","metaTitle":"ST STM32L051C6T6 ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L051C6T6 32-bit MCU, ARM Cortex-M0+ core at 32 MHz, 32 KB Flash, 8 KB SRAM, 2 KB EEPROM, 48-LQFP, -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":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K 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":"37","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","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":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4480b8ddc40b685393082b7ee2561685.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L051C6T6?","answer":"The STM32L051C8T6 is pin-compatible and offers 64 KB Flash instead of 32 KB, in the same 48-LQFP package with the same supply range and peripherals.
