The exposed thermal pad needs a via-stitched ground plane on the PCB to pull heat out of the die; without it, continuous operation above 70°C ambient at full I/O load will push junction temperature. The 5x5 mm footprint fits tight layouts in handheld or wearable designs. ## Peripherals and connectivity for control-loop tasks With 30 I/O lines available, this MCU can handle a modest keypad plus a small character LCD and still leave pins for a serial debug header. STMicroelectronics lists the STM8L101K3U6TR as Active (current production).","metaTitle":"STM8L101K3U6TR 8-bit MCU, STM8L EnergyLite, 16 MHz","metaDescription":"STM8L101K3U6TR 8-bit MCU from STM8L EnergyLite series. 16 MHz core, 8 KB Flash, 1.5 KB RAM, 2 KB EEPROM, 1.65V-3.6V supply.","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)","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":"30","Core Processor":"STM8","Package / Case":"32-UFQFN Exposed Pad","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":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0449","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c575074f8f2dd9684cfa819dce3a3ab7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L101K3U6TR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L101K3U6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L101K3U6TR when reusing this data.
