X5323 CPU Supervisor

DATASHEET X5323, X5325 (Replaces X25323, X25325) CPU Supervisor with 32kBit SPI EEPROM FN8131 Rev 3.00 December 9, 2015 These devices combine four popular functions, Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. Applying power to the device activates the power-on reset circuit which holds RESET/RESET active for a pe.
