The 128-byte EEPROM handles calibration constants and configuration parameters without wearing the Flash. If the application grows beyond this memory envelope, consider stepping up to the STM8S003F3 variant with 8 KB Flash and 1 KB RAM in a smaller package, or the STM8S105 family for 16 KB Flash and 2 KB RAM. That covers most indoor and outdoor equipment — appliance control panels, HVAC fan coils, LED lighting drivers, and basic motor drives.","metaTitle":"STMicroelectronics STM8S003K3T6CTR 8-bit MCU, 16 MHz","metaDescription":"STMicroelectronics STM8S003K3T6CTR 8-bit MCU, 16 MHz core, 8 KB Flash, 1 KB RAM, 128 B EEPROM, 28 I/O, -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":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"1K x 8","Core Size":"8-Bit","EEPROM Size":"128 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":"28","Core Processor":"STM8","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 4x10b","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":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2.95V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f9bbd7cc38533f2d818e2d311349223e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8S003K3T6CTR/alternatives.json"},"ai":{"faq":[{"question":"Does STM8S003K3T6CTR have an integrated ADC?","answer":"Yes, it includes a 4-channel 10-bit analog-to-digital converter.
