Datasheet Summary
X5323, X5325 (Replaces X25323, X25325)
CPU Supervisor with 32kBit SPI EEPROM
FN8131 Rev 3.00 December 9, 2015
These devices bine four popular functions, Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory in one package. This bination 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 period of time. This allows the power supply and oscillator to stabilize before the processor can execute code.
The Watchdog Timer provides an independent protection mechanism for microcontrollers....
