The 25 general-purpose I/O pins are enough to handle a keypad, a small character display, and a few discrete sensors without an external port expander. The small footprint suits space-constrained PCBs in compact enclosures.","metaTitle":"ST STM8S105K6U6A 8-bit MCU, 16 MHz, 32 KB Flash, UFQFPN-32","metaDescription":"STM8S105K6U6A 8-bit MCU from STMicroelectronics: 16 MHz core, 32 KB Flash, 2 KB RAM, 1 KB EEPROM, -40°C to 85°C.","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":"Tray","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-UFQFN Exposed Pad","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-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"2.95V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/79a5231aeb7b67b40c4d895563a236b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8S105K6U6A/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM8S105K6U6A and STM8S105K4U6A?","answer":"The primary difference is program memory density: the STM8S105K6U6A has 32 KB of Flash, while the STM8S105K4U6A has 16 KB. Both share the same 16 MHz STM8 core, 2 KB RAM, 1 KB EEPROM, peripheral set, and 32-UFQFPN package — so they are pin-compatible and differ only in firmware storage capacity. Choose the K6 variant when the code image exceeds the 16 KB limit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8S105K6U6A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8S105K6U6A when reusing this data.
