It handles sensor polling, UART/I²C/SPI communication, and simple control loops without breaking a sweat. ## Memory budget: 8 KB Flash, 1.5 KB RAM, 2 KB EEPROM 8 KB of program Flash is tight but workable for a single-purpose controller — think a fan motor driver or a temperature monitor. The 2 KB EEPROM is a real advantage: calibration constants, fault logs, or configuration parameters survive power loss without external storage. 1.5 KB RAM limits buffering, so plan for small packet sizes on the UART. ## Package: 28-UFQFPN, 4x4 mm The 28-pin UFQFPN (4x4 mm) is a compact QFN-style package with an exposed pad.","metaTitle":"ST STM8L101G3U6A 8-bit MCU, 16 MHz, 8KB Flash, 28-UFQFPN","metaDescription":"STMicroelectronics STM8L101G3U6A 8-bit MCU from STM8L EnergyLite series. 16 MHz core, 8KB Flash, 1.5KB RAM, 2KB EEPROM, -40°C to 85°C, 28-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":"Tray","RAM Size":"1.5K x 8","Core Size":"8-Bit","EEPROM Size":"2K x 8","Peripherals":"Infrared, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"26","Core Processor":"STM8","Package / Case":"28-UFQFN","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-UFQFPN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9399","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c575074f8f2dd9684cfa819dce3a3ab7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L101G3U6A/alternatives.json"},"ai":{"faq":[{"question":"What package does STM8L101G3U6A come in?","answer":"It is supplied in a 28-UFQFPN package measuring 4x4 mm, with an exposed thermal pad.
