The base product number STM32L051 covers a range of Flash and package options; if a future capacity constraint hits the C8T7 variant, a pin-compatible sibling within the same family (different Flash size or temperature grade) can be swapped without a board respin. ## Package and placement notes for the assembly line The 48-LQFP (7x7 mm body, 0.5 mm pitch) is a standard JEDEC footprint that runs well on any modern pick-and-place. No exposed pad means no thermal-via stitching is required — the part dissipates through the leads. The shipping medium is tray, which is the usual format for LQFP; if your feeder prefers tape, the same die in a T&R variant (STM32L051C8T7TR) is available.","metaTitle":"ST STM32L051C8T7 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L051C8T7 32-bit MCU: ARM Cortex-M0+ core at 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 1.65V-3.6V supply, -40°C to 105°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":"37","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b","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":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4480b8ddc40b685393082b7ee2561685.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L051C8T7 and STM32L051C8T6?","answer":"Both share the same 48-LQFP package, 64 KB Flash, 8 KB RAM, and 2 KB EEPROM.
