Brown-out detect and POR are integrated, so the reset circuit on the board can be minimal. If you are starting a new design, ST's current automotive MCU families (STM8A successor lines or STM32A) should be evaluated for form-fit-function compatibility.","metaTitle":"STM8AF52A9TAY 8-bit MCU, 24 MHz, 128 KB Flash, 64-LQFP","metaDescription":"STM8AF52A9TAY 8-bit automotive MCU from STMicroelectronics. 24 MHz core, 128 KB Flash, 6K x 8 RAM, 2K x 8 EEPROM, CAN/LIN.
