The 1K x 8 EEPROM stores calibration constants or configuration parameters that survive power cycles without external serial memory — useful for field-set thresholds or node addresses. ## Peripheral set for sensor and actuator control The 7-channel 10-bit ADC reads analog sensors (thermistors, potentiometers, current shunts) without an external converter — enough resolution for threshold detection and slow-loop feedback. Built-in brown-out detect and POR eliminate external reset supervisor ICs in cost-sensitive designs; the PWM outputs drive LEDs, small DC motors, or solenoid valves directly through a driver transistor. ## Package and board integration — 32-LQFP 7x7 mm The 32-LQFP package with 0.8 mm pitch and a 7x7 mm body is a standard footprint — two-layer boards fan out the peripheral pins without blind vias, and hand-soldering or rework is straightforward with a fine-tip iron.","metaTitle":"STM8S105K6T6CTR 8-bit MCU, 16MHz, 32KB Flash, 2.95-5.5V","metaDescription":"STMicroelectronics STM8S105K6T6CTR 8-bit MCU: 16MHz STM8 core, 32KB Flash, 2K RAM, 1K EEPROM, 25 I/O, -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":"STM8S","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"STM8","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 7x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2.95V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/79a5231aeb7b67b40c4d895563a236b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8S105K6T6CTR/alternatives.json"},"ai":{"faq":[{"question":"How much flash memory does STM8S105K6T6CTR have?","answer":"32 KB (32K x 8) of program flash, with 2K x 8 SRAM and 1K x 8 EEPROM for data storage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8S105K6T6CTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8S105K6T6CTR when reusing this data.
