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 VCC 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.
