BU9831 Datasheet | ROHM

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 munications, 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 puters, and other sound adjustment devices for sets Features - 1) Internal 2k bit EEPROM 2) 100kΩ (1kΩ × 100 steps) electronic potentiometer 3) Data in memory is automatically read when power supply is turned on, and...
