This document is the user manual of x9313, which introduces the basic characteristics and usage methods of the product.
The X9313 is a digitally controlled potentiometer (XDCP) that integrates a 31‑element resistor array, wiper switches, a control section, and non‑volatile memory. It offers 32 selectable tap positions via a 3‑wire serial interface and can store the wiper position in non‑volatile memory for recall on power‑up.
Key features include a supply voltage range of 3 V to 5 V, active current up to 3 mA, standby current as low as 500 µA, temperature‑compensated operation from –40 °C to +85 °C, and data retention of 100 years. The device is offered in multiple plastic packages (SO, MSOP, PDIP) with both leaded and Pb‑free options.
