Description and Introduction

Dual E2POT? Nonvolatile Digital Potentiometer Part X9221WS is manufactured by XICOR. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Digital Potentiometer (DCP)  
- **Interface:** Serial (SPI-compatible)  
- **Resolution:** 256 taps (8-bit)  
- **Number of Channels:** Single  
- **Resistance Range:** Typically 10kΩ  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The X9221WS is a digitally controlled potentiometer (DCP) that replaces mechanical potentiometers.  
- It provides non-volatile storage of wiper settings, ensuring retention of the last position after power-off.  
- It is designed for applications requiring precision adjustments via digital signals.  

### **Features:**  
- **Non-Volatile Memory:** Retains wiper position without power.  
- **SPI Interface:** Allows easy digital control.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **End-to-End Resistance Tolerance:** ±20% (typical).  
- **Incremental/Decremental Control:** Supports step adjustments.  
- **Wide Operating Voltage:** Compatible with 3V and 5V systems.  

For exact values, refer to the official XICOR datasheet.
