The 2 KB EEPROM is useful for storing configuration parameters or calibration constants that survive power cycles without wearing the Flash. ## Package and footprint for space-constrained boards The 26 I/O lines provide enough headroom for a keypad matrix, a few LEDs, and the serial bus, leaving a handful of pins for interrupts or ADC inputs. Surface-mount assembly is straightforward with standard reflow profiles for the UFQFPN land pattern. ## Lifecycle and sourcing — still active for new designs","metaTitle":"ST STM8L101G3U6TR 8-bit MCU, 16 MHz, 8 KB Flash, 1.5 KB SRAM","metaDescription":"STMicroelectronics STM8L101G3U6TR: 8-bit STM8 core at 16 MHz, 8 KB Flash, 1.5 KB SRAM, 2 KB EEPROM, 26 I/O, I²C/SPI/USART, 1.65–3.6 V, -40 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":"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":"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/STM8L101G3U6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM8L101G3U6TR equivalent to STM8L101G3U3?","answer":"The STM8L101G3U3 is a sibling variant with the same core and memory but in a different package — verify the package and temperature grade against your BOM before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8L101G3U6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8L101G3U6TR when reusing this data.
