Every unit sourced through independent channels should be inspected for date-code consistency, marking integrity, and package condition. This is an 8-bit STM8 core MCU running at 16 MHz with 32 KB of program Flash, 2 KB of SRAM, and 1 KB of dedicated EEPROM. That memory profile targets small-footprint control applications: sensor readout, basic motor commutation, LIN-bus node modules, or I²C/SPI bridge functions. The 25 available I/O lines and the 7-channel 10-bit ADC (A/D 7x10b) give enough analog input headroom for a three-phase current-sense plus a few temperature or voltage monitor points. The Brown-out Detect/Reset and POR peripherals are standard for industrial reliability. ## 32-VFQFN (5x5 mm) — board integration notes The package is a 32-lead VFQFN with an exposed thermal pad, measuring 5x5 mm. The pad is the primary heat sink; the plastic overmold alone cannot dissipate the core and I/O switching losses.","metaTitle":"STM8S105K6U6 STMicroelectronics 8-bit MCU, 32KB Flash","metaDescription":"Obsolete STM8S105K6U6 8-bit MCU from STMicroelectronics. 32KB Flash, 2KB RAM, 1KB EEPROM, 16 MHz, 25 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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-VFQFN Exposed Pad","Product Status":"Obsolete","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-VFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"2.95V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/79a5231aeb7b67b40c4d895563a236b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8S105K6U6/alternatives.json"},"ai":{"faq":[{"question":"Is STM8S105K6U6 obsolete?","answer":"Yes.
