X4023x
Integrated System Management IC
Triple Voltage Monitors, POR, 2 kbit EEPROM Memory, and Single/Dual DCP
DESCRIPTION
The X4023x family of Integrated System Management
ICs combine CPU Supervisor functions (V
Reset (POR) circuitry, two additional programmable volt-
age monitor inputs with software and hardware indica-
tors), integrated EEPROM with Block Lock
and one or two Xicor Digitally Controlled Potentiometers
(XDCP). All functions of the X4023x are accessed by an
industry standard 2-Wire serial interface.

APPLICATIONS
The DCP of the X4023x may be utilized to software con-
trol analog voltages for:
– LCD contrast, LCD purity, or Backlight control.
– Power Supply settings such as PWM frequency, Voltage
Trimming or Margining (temperature offset control).
– Reference voltage setting (e.g. DDR-SDRAM SSTL-2)
The 2 kbit integrated EEPROM may be used to store ID,
manufacturer data, maintenance data and module defini-
tion data.
The programmable POR circuit insures V
before RESET is removed and protects against brown-
outs and power failures. The programmable voltage mon-
itors have on-chip independent reference alarm levels.
With separate outputs, the voltage monitors can be used
for power on sequencing.
