The PCB layout engineer should note that the 64-LQFP (10x10 mm) package routes all 51 I/O to the periphery, so decoupling caps can sit close to the Vdd/Vss pairs without crowding the center of the board. The 16-channel 12-bit ADC and single 12-bit DAC cover basic analog front-end needs — reading a thermistor string or generating an analog setpoint. The USB interface with integrated PHY simplifies adding a USB-to-serial bridge for field firmware updates. The programming interface is SWD (Serial Wire Debug) via the standard 4-pin connector; the SWD pins are not shared with any other function on this package, so the debug port stays alive even if the application firmware locks the GPIOs. ## Lifecycle and procurement reality This part is currently in volume production and is stocked across multiple independent distribution channels. The ROHS3 compliance is current for EU and global markets.","metaTitle":"STM32L052R8T6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052R8T6 32-bit MCU with ARM Cortex-M0+ core, 32 MHz speed, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 64-LQFP package.","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":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; 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":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0100","priceTiers":[{"qty":1,"price":"$5.01000","currency":"USD"},{"qty":10,"price":"$4.49600","currency":"USD"},{"qty":25,"price":"$4.25040","currency":"USD"},{"qty":160,"price":"$3.68363","currency":"USD"},{"qty":320,"price":"$3.49472","currency":"USD"},{"qty":480,"price":"$3.13581","currency":"USD"},{"qty":960,"price":"$2.64466","currency":"USD"},{"qty":2400,"price":"$2.51243","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0e08a9b8947f5c1faa7dae988a3ee99f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L052R8T6/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052R8T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052R8T6 when reusing this data.
