It handles UART polling, I²C sensor reads, and PWM generation. ## 64-TFBGA — plan the rework before you need it This comes in a 64-ball TFBGA, 5x5 mm body. That is a fine-pitch BGA — 0.5 mm ball pitch typically — which means a four-layer PCB minimum to route the signals out, and a hot-air station or reflow oven for assembly. Not a hand-solder part. If your production volume is low or you are doing field repairs, the LQFP-64 variant of the same MCU (STM32L052R8T6) is a more serviceable choice. The TFBGA saves board area but adds a rework step. ## Industrial temperature, but not automotive Not qualified to AEC-Q100, so do not spec it for under-hood or safety-critical automotive without a waiver. ## Active and available — no LTB clock ticking No end-of-life notice, no last-time-buy deadline.","metaTitle":"STM32L052R8H6 STM32L0 MCU, 32MHz Cortex-M0+, 64KB Flash","metaDescription":"STM32L052R8H6 32-bit ARM Cortex-M0+ MCU at 32MHz, 64KB Flash, 8KB RAM, 2KB 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":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-TFBGA","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-TFBGA (5x5)","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":"$4.29400","currency":"USD"},{"qty":25,"price":"$4.05920","currency":"USD"},{"qty":80,"price":"$3.51788","currency":"USD"},{"qty":230,"price":"$3.33752","currency":"USD"},{"qty":640,"price":"$2.99475","currency":"USD"},{"qty":1280,"price":"$2.52569","currency":"USD"},{"qty":2560,"price":"$2.39940","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0e08a9b8947f5c1faa7dae988a3ee99f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L052R8H6/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L052R8H6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L052R8H6 when reusing this data.
