Description

The X4023x family of Integrated System Management ICs combine CPU Supervisor functions (V_CC Power-onpower-on Reset (POR) circuitry, two additional programmable voltage monitor inputs with software and hardware indicators), integrated EEPROM with Block Lock™ 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.

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, 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 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 monitors can be used for power-on sequencing.
