This document is a function introduction document for X9C102, X9C103, X9C104, X9C503
The X9C102 series are Intersil digitally controlled potentiometers (xDCP™) featuring a 99‑element resistor array, 100 wiper tap points, and non‑volatile memory to retain the wiper position on power‑up. The device is controlled via a three‑wire serial interface (CS, INC, U/D) and can operate as a three‑terminal potentiometer or a two‑terminal variable resistor.
The datasheet details absolute maximum ratings, recommended operating conditions, electrical characteristics, package dimensions for 8‑lead SOIC and PDIP versions, and programming procedures for storing and recalling the wiper position.
