The STM8S003F3U6TR is a 8-bit 20-pin value line Microcontroller Unit offers 8kB of flash program memory, plus integrated true data EEPROM and this value line device provides the following benefits of performance and robustness. The device performance and robustness are ensured by true data EEPROM supporting up to 100000 write/erase cycles, advanced core and peripherals made in a state-of-the-art technology at 16MHz clock frequency, robust I/Os, independent watchdogs with separate clock source and a clock security system.
Communications interfaces - SPI interface up to 8Mbit/s
UART with clock output for synchronous operation, SmartCard, IrDA, LIN master mode
Highly robust I/O design, immune against current injection
Interrupt management - Up to 27 external interrupts on 6 vectors
Nested interrupt controller with 32 interrupts
Embedded single-wire interface module for fast on-chip programming and non-intrusive debugging
