Description and Introduction

Dual E2POT? Nonvolatile Digital Potentiometer Part X9221YS is manufactured by XICOR. Below are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Type:** Digital Potentiometer (Digitally Programmable Potentiometer - DPP)  
- **Interface:** Serial (SPI-compatible)  
- **Resolution:** 256 taps  
- **Number of Channels:** Single  
- **End-to-End Resistance:** 10 kΩ, 50 kΩ (options available)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Temperature Range:** Industrial (-40°C to +85°C)  
- **Non-Volatile Memory:** Yes (EEPROM stores wiper position)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The X9221YS is a digitally controlled potentiometer (DCP) that provides a non-volatile, programmable resistance via a serial interface. It is designed to replace mechanical potentiometers in applications requiring precision adjustments. The device includes an integrated EEPROM to retain settings when power is removed.  

### **Features:**  
- **Non-Volatile Wiper Storage:** Saves position in EEPROM  
- **Low Power Consumption:** Ideal for battery-operated devices  
- **Incremental/Decremental Control:** Allows precise adjustments  
- **SPI-Compatible Serial Interface:** Easy integration with microcontrollers  
- **High Reliability:** 100,000 write cycles endurance  
- **Wide Operating Voltage:** Supports both 3V and 5V systems  

For exact details, always refer to the official XICOR datasheet.
