The 2 KB EEPROM is a separate block — no wear-leveling needed for infrequent parameter writes like calibration offsets or serial numbers. If your application needs over-the-air updates or a larger protocol stack, you will bump into the Flash ceiling; the STM8L151 series with up to 32 KB is the next step up in the same EnergyLite family.","metaTitle":"ST STM8L101K3T6TR 8-bit MCU, 16 MHz, 8 KB Flash, 32-LQFP","metaDescription":"STMicroelectronics STM8L101K3T6TR 8-bit MCU, 16 MHz core, 8 KB Flash, 1.5 KB RAM, 2 KB EEPROM, -40°C to 85°C, 32-LQFP.","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-LQFP","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-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0316","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c575074f8f2dd9684cfa819dce3a3ab7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8L101K3T6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM8L101K3T6TR obsolete?","answer":"No."},{"question":"Does STM8L101K3T6TR have UART?","answer":"Yes, it includes UART/USART connectivity alongside I²C and SPI interfaces."},{"question":"Is STM8L101K3T6TR compatible with ST-Link?","answer":"Yes, ST-Link supports the STM8 family via the SWIM (Single Wire Interface Module) protocol, which is the standard debug/programming interface for this MCU."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L101K3T6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L101K3T6TR when reusing this data.
