BU9831 Datasheet (Rohm) - Non-volatile electronic potentiometer

BU9831, Non-volatile electronic potentiometer

Memory ICs Non-volatile electronic potentiometer BU9831 / BU9831F The BU9831 / BU9831F is a non-volatile electronic potentiometer with an internal 2k bit EEPROM.

The resistance value can be set by means of serial communications, and because the product contains an internal memory, conditions can be retained.

In addition, the 2k bit memory capacity enables digital data to be stored in the memory.

Applications Portable LCD backlight adjustment devices for notebook computers, and other s
