DESCRIPTION
   The X4023x family of Integrated System Management ICs combine CPU Supervisor functions (VCC Power-onpower-on Reset (POR) circuitry, two additional programmable voltage monitor inputs with software and hardware indicators), integrated EEPROM with Block LockTM protection and one or two Intersil Digitally Controlled Potentiometers (XDCP). All functions of the X4023x are accessed by an industry standard 2-Wire serial interface.
