The 18 GPIOs, combined with I²C, SPI, and UART, give enough headroom to interface with a small display, a few sensors, and a serial link without needing external expanders. ## Active lifecycle — no near-term obsolescence concern For supply assurance, we source this part through authorized distribution channels and can quote current pricing and availability against an RFQ.","metaTitle":"STM8L101F1U6ATR STM8L EnergyLite 8-bit MCU, 16 MHz","metaDescription":"STMicroelectronics STM8L101F1U6ATR 8-bit MCU with 16 MHz STM8 core, 2 KB Flash, 1.5 KB RAM, I²C/SPI/UART, 1.65 V–3.6 V, -40°C to 85°C, 20-UFQFPN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"STM8L EnergyLite","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"1.5K x 8","Core Size":"8-Bit","EEPROM Size":"-","Peripherals":"Infrared, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"18","Core Processor":"STM8","Package / Case":"20-UFQFN","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"2KB (2K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-UFQFPN (3x3)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c575074f8f2dd9684cfa819dce3a3ab7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L101F1U6ATR/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for STM8L101F1U6ATR?","answer":"We source the STM8L101F1U6ATR through authorized distribution channels.
