With 37 GPIOs in the 48-LQFP package, most designs will have headroom for local sensors, a small display, or an external memory interface.","metaTitle":"STM32L051C8T3 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L051C8T3 32-bit MCU, ARM Cortex-M0+ core at 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, -40 to 125°C, 48-LQFP.","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":"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":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7800","priceTiers":[{"qty":1,"price":"$4.78000","currency":"USD"},{"qty":10,"price":"$4.29200","currency":"USD"},{"qty":25,"price":"$4.05760","currency":"USD"},{"qty":80,"price":"$3.51650","currency":"USD"},{"qty":250,"price":"$3.33620","currency":"USD"},{"qty":500,"price":"$2.99356","currency":"USD"},{"qty":1000,"price":"$2.52470","currency":"USD"},{"qty":2500,"price":"$2.39846","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4480b8ddc40b685393082b7ee2561685.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L051C8T3/alternatives.json"},"ai":{"faq":[{"question":"Can STM32L051C8T3 replace STM32L051C8T6?","answer":"The T3 variant is the extended-temperature version of the same base part, rated to 125°C versus the T6's 85°C. Electrically and functionally they are identical, so the T3 can replace a T6 in any design, but the reverse is only safe if the application never exceeds 85°C ambient."},{"question":"What is the difference between STM32L051C8T3 and STM32L151CBU6A?","answer":"The STM32L151CBU6A uses a Cortex-M3 core (same 32 MHz speed) and adds USB, DAC, and capacitive-sensing peripherals, but its temperature range stops at 85°C.
