The 2 KB EEPROM is a real differentiator: it stores calibration constants, configuration parameters, or device identity data without needing external serial EEPROM or wear-leveling in Flash. That saves both BOM cost and board area.","metaTitle":"STM32L052K6U6TR ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L052K6U6TR 32-bit MCU based on ARM Cortex-M0+ core, 32 MHz, 32 KB Flash, 8 KB SRAM, 2 KB EEPROM, industrial temp -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":"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, USB","Mounting Type":"Surface Mount","Number of I/O":"27","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-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":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9500","priceTiers":[{"qty":1,"price":"$3.95000","currency":"USD"},{"qty":10,"price":"$3.54500","currency":"USD"},{"qty":25,"price":"$3.35120","currency":"USD"},{"qty":100,"price":"$2.90420","currency":"USD"},{"qty":250,"price":"$2.75528","currency":"USD"},{"qty":500,"price":"$2.47232","currency":"USD"},{"qty":1000,"price":"$2.08508","currency":"USD"},{"qty":3000,"price":"$1.98083","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0e08a9b8947f5c1faa7dae988a3ee99f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L052K6U6TR/alternatives.json"},"ai":{"faq":[{"question":"What package does STM32L052K6U6TR use?","answer":"It comes in a 32-UFQFN package with exposed pad, also designated 32-UFQFPN (5x5 mm).
