DESCRIPTION
The X4023x family of Integrated System Manage-
ment ICs combine CPU Supervisor functions (V CC
Power-onpower-on Reset (POR) circuitry, two addi-
tional programmable voltage monitor inputs with soft-
ware and hardware indicators), integrated EEPROM
with Block Lock TM protection and one or two Intersil
Digitally Controlled Potentiometers (XDCP). All func-
tions of the X4023x are accessed by an industry
standard 2-Wire serial interface.
APPLICATIONS
The DCP of the X4023x may be utilized to software
control analog voltages for:
– LCD contrast, LCD purity, or Backlight control.
– Power Supply settings such as PWM frequency,

definition data.
The programmable POR circuit insures V CC is stable
before RESET is removed and protects against
brown-outs and power failures. The programmable
voltage monitors have on-chip independent reference
alarm levels. With separate outputs, the voltage moni-
tors can be used for power-on sequencing.
