The Tape & Reel variant (TR suffix) is the standard for automated pick-and-place assembly. No exposed thermal pad — standard TSSOP land pattern applies.","metaTitle":"ST STM8S103F3P6TR 8-bit MCU, 16 MHz, 8 KB Flash, 20-TSSOP","metaDescription":"STMicroelectronics STM8S103F3P6TR 8-bit MCU: 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, 2.95-5.5 V supply, -40 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":"640 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":"16","Core Processor":"STM8","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"A/D 5x10b","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":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"2.95V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3674b3c362c7ea11e333a829b5df608a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8S103F3P6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM8S103F3P6TR?","answer":"Within the STM8S value line, the STM8S003F3P6 is a common pin-compatible alternative with the same 20-TSSOP footprint, 16 MHz core, and peripheral set, though it has 8 KB Flash versus 8 KB here — essentially the same memory tier. The STM8S103F3P6TR offers a slightly richer feature set with the full STM8S peripheral complement. For a direct drop-in, verify the exact Flash and EEPROM sizes against your firmware image."},{"question":"What is STM8S103F3P6TR's listed speed?","answer":"The core runs at 16 MHz, which is the maximum clock frequency for this STM8S family member. That is sufficient for typical 8-bit control tasks like sensor polling, PWM generation at audio-range frequencies, and UART communication up to 1 Mbps."},{"question":"What compliance documentation is available for STM8S103F3P6TR?","answer":"STMicroelectronics provides RoHS and REACH compliance declarations for this part as standard.
