Brown-out detect and POR are integrated, so the reset circuit is minimal. ## Peripheral set for serial communication and PWM control The 10-channel 10-bit ADC handles analog inputs like potentiometers, thermistors, or current-sense resistors.","metaTitle":"ST STM8S105C4T3TR 8-bit MCU, 16 MHz, 16 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM8S105C4T3TR 8-bit MCU: 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, -40 to 125°C, 48-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)","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":"38","Core Processor":"STM8","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 10x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2.95V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5704","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/79a5231aeb7b67b40c4d895563a236b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8S105C4T3TR/alternatives.json"},"ai":{"faq":[{"question":"What is STM8S105C4T3TR's listed speed?","answer":"The core runs at 16 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8S105C4T3TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8S105C4T3TR when reusing this data.
