On-chip peripherals include I²C, SPI, UART/USART, USB, I²S, DMA, PWM, and a 12-bit ADC with 10 channels plus a single 12-bit DAC. The brown-out detect and POR blocks simplify power sequencing — no external supervisor needed for most battery-powered applications.","metaTitle":"STM32L052C8U6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052C8U6 32-bit MCU, ARM Cortex-M0+ core at 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 1.65V-3.6V supply, -40°C to 85°C.","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, USB","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; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L052","Program Memory Size":"64KB (64K 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":"$4.4300","priceTiers":[{"qty":1,"price":"$4.43000","currency":"USD"},{"qty":10,"price":"$3.98200","currency":"USD"},{"qty":25,"price":"$3.76400","currency":"USD"},{"qty":80,"price":"$3.26225","currency":"USD"},{"qty":260,"price":"$3.09500","currency":"USD"},{"qty":520,"price":"$2.77712","currency":"USD"},{"qty":1040,"price":"$2.34215","currency":"USD"},{"qty":2600,"price":"$2.22504","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a2573a105b6cdfd7c3c952ee290c214b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L052C8U6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L052C8U6 and STM32L052C8T6?","answer":"The difference is the package: the C8U6 variant comes in a 48-UFQFN exposed-pad package, while the C8T6 uses a 48-LQFP.
