This file introduces the features and characteristics of the Xicor X9312 nonvolatile potentiometer.
The Xicor X9312 is a solid‑state non‑volatile digital potentiometer designed for digitally controlled resistance trimming. It contains a resistor array of 99 elements with 100 wiper tap points, controlled via three‑wire inputs (CS, U/D, INC). The device stores the wiper position in non‑volatile memory and recalls it on power‑up, offering up to 100‑year data retention.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, recommended operating conditions for commercial, industrial, and military environments, and packaging information. Typical specifications include a ±20 % resistance tolerance, 40 Ω wiper resistance at 1 mA, and a supply voltage range of 0‑15 V.
| Wiper tap points | 100 |
|---|---|
| Supply voltage range | 0 V to +15 V |
| End‑to‑end resistance tolerance | ±20 % |
| Wiper resistance (typical) | 40 Ω at 1 mA |
| Data retention (non‑volatile) | 100 years |
| Maximum storage cycles | 10,000 |
The wiper position is stored in non‑volatile memory when the CS input transitions HIGH while the INC input is also HIGH.
The device operates with a supply voltage from 0 V up to +15 V.
Commercial: 0 °C to +70 °C; Industrial: –40 °C to +85 °C; Military: –55 °C to +125 °C.
Typical wiper resistance is about 40 Ω at a current of 1 mA.
