The 8 KB RAM is the tighter constraint — buffer-heavy designs like audio capture or high-rate ADC logging will bump against it. The integrated 2 KB EEPROM saves the cost and board space of an external serial EEPROM for calibration coefficients or device configuration that survives a firmware update. ## 64-TFBGA — what the rework bench needs to know The 64-TFBGA (5x5 mm) is a fine-pitch BGA with no exposed pad. The 0.5 mm ball pitch means via-in-pad or microvias on the top layer if you route all 51 I/Os out. On the rework side: it needs a pre-bake if the moisture-barrier bag has been open past the floor-life window (MSL 3 typical for this package class). Hot-air profile at 240°C peak, bottom preheat to 120°C, and a stencil that deposits enough paste volume to avoid head-in-pillow. This is not a hand-solder part; plan for a reflow oven or a professional BGA rework station. ## Peripherals and connectivity for industrial IoT The 16-channel 12-bit ADC covers multi-sensor acquisition. ## Industrial temperature range and environment The 105°C ceiling gives thermal margin above the usual 85°C industrial limit, which matters when the MCU sits near a power stage or in a sealed enclosure. The base product number STM32L051 covers multiple Flash and package variants, so if a future BOM needs more memory or a different footprint, the migration path stays within the same family.","metaTitle":"STM32L051R8H7 STMicroelectronics ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STM32L051R8H7 32-bit ARM Cortex-M0+ MCU at 32 MHz with 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 51 I/Os in 64-TFBGA.","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":"Tube","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":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"64-TFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3062","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4480b8ddc40b685393082b7ee2561685.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can STM32L051R8H7 be used as a replacement for STM32L051R8H6?","answer":"The STM32L051R8H7 and STM32L051R8H6 share the same base product number STM32L051, indicating they are part of the same family.
