INTERSIL X9C102/X9C103/X9C104/X9C503 Manual
The X9Cxxx series are Intersil digitally controlled potentiometers (XDCP) that combine a 99‑element resistor array, wiper switches, a control section, and non‑volatile memory. The devices support a three‑wire serial interface, provide 100 wiper tap points, and can store the wiper position in non‑volatile memory for recall on power‑up.
The datasheet details absolute maximum ratings, recommended operating conditions, electrical characteristics, pin functions, programming procedures, and package dimensions for both SOIC and PDIP variants. It also includes endurance and data‑retention specifications for reliable long‑term use.
