The low-voltage floor lets it stay alive during battery discharge without a boost converter. ## Peripherals and I/O The peripheral set also includes a brown-out detect/reset, DMA, I²S, PWM, and a watchdog timer. ## Package and thermal pad Housed in a 48-lead UFQFPN with an exposed pad (7x7 mm body), the package allows a low-profile, surface-mount assembly. ## Lifecycle and sourcing posture STMicroelectronics lists the STM32L051C6U6 as an active product.","metaTitle":"STM32L051C6U6 ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STM32L051C6U6 32-bit MCU from STMicroelectronics, ARM Cortex-M0+ core at 32 MHz, 32 KB Flash, 8 KB SRAM, 2 KB EEPROM, 37 I/O, -40 to 85 °C, 48-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":"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-UFQFN Exposed Pad","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-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3833","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/11faa23d4097e869e8ac05568e64748d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the equivalent parts for STM32L051C6U6?","answer":"Within the STM32L0 family, the STM32L051C6T6 is a close pin-compatible sibling, differing mainly in package (LQFP-48 instead of UFQFPN).
