The 8 KB RAM is tight for heavy buffering; if your application streams USB audio or runs a real-time OS with multiple stacks, budget the RAM carefully. The 64 KB Flash is typical for a sensor hub, simple HMI controller, or USB dongle firmware. ## Supply range and operating temperature — battery and industrial ready If your design needs 105°C or 125°C, this is not the variant — look at the STM32L0 extended-temp siblings. ## Connectivity and peripherals — USB, I²C, SPI, UART, LCD drive It also integrates a segment LCD controller, which is rare in this package size — useful for battery-powered meters or handheld instruments with a simple glass LCD. The 37 I/O lines in a 48-pin package leave room for a parallel display or keypad matrix. ## Package and footprint — 48-UFQFPN with exposed pad The pad is not optional — without it, the junction temperature rises quickly at higher clock speeds or with multiple peripherals active. The 0.5 mm pitch is standard for hand-solder rework with a hot-air station.","metaTitle":"STM32L063C8U6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L063C8U6 32-bit MCU with 32 MHz ARM Cortex-M0+ core, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, USB, industrial temp -40 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, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L063","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6360","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69aa2b504b063c6adb607ce3bea7203b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L063C8U6 support USB?","answer":"Yes, the connectivity list includes USB, along with I²C, IrDA, SPI, and UART/USART.
