The X9C102, X9C103, X9C104, X9C503 Digitally Controlled Potentiometer (XDCP™) is a solid-state potentiometer with 3-wire serial interface, 100 wiper tap points, wiper position stored in nonvolatile memory and recalled on power-up, 99 resistive elements, temperature compensated, ±20% end to end resistance, ±5V terminal voltages, low power CMOS, VCC = 5V, 3mA max. active current, 750µA max. standby current, 100 years register data retention, and 100,000 data changes per bit (Endurance).
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.
| Wiper tap points | 100 |
|---|---|
| Resistive elements | 99 |
| Supply voltage (VCC) | 5 V |
| Active current (max) | 3 mA |
| Wiper resistance (typical) | 40 Ω |
| Endurance (data changes per bit) | 100 000 |
| Data retention | 100 years |
| Operating temperature range (industrial) | -40 °C to +85 °C |
