Product Summary
The stm8af51aata/c is an Automotive 8-bit MCU, with up to 128 Kbytes Flash, data EEPROM, c ADC, timers, LIN, CAN, USART, SPI, I2C, 3 to 5.5 V. The system cost is reduced thanks to an integrated true data EEPROM for up to 300 k write/erase cycles and a high system integration level with internal clock oscillators, watchdog, and brown-out reset. Device performance is ensured by 20 MIPS at 24 MHz CPU clock frequency and enhanced characteristics which include robust I/O, independent watchdogs (with a separate clock source), and a clock security system.
