The 0.5 mm ball pitch means a 4-layer board with microvias is the practical minimum for routing all 51 I/O plus supply and ground. Under the hot-air station, pre-bake at 125°C for 24 hours if the moisture-barrier bag has been open past the floor life; MSL 3 is typical for this class. Will it survive rework? Yes, with a decent preheat and a rework nozzle sized to the body. The small thermal mass reflows cleanly. ## Supply range and power budget At 32 MHz the core draws in the low milliamps range; stop-mode current is typically under 2 µA with the RTC running.","metaTitle":"ST STM32L051R6H6 ARM Cortex-M0+ MCU, 32MHz, 32KB Flash","metaDescription":"STMicroelectronics STM32L051R6H6 32-bit ARM Cortex-M0+ MCU, 32MHz, 32KB Flash, 8KB SRAM, 2KB EEPROM, 64-TFBGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-TFBGA","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L051","Program Memory Size":"32KB (32K 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":"$2.5063","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4480b8ddc40b685393082b7ee2561685.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L051R6H6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L051R6H6 when reusing this data.
