Description and Introduction

E 2 POT TM Nonvolatile Digital Potentiometer Part X9315WM is manufactured by Intersil (now part of Renesas Electronics). Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Digitally Controlled Potentiometer (XDCP)  
- **Resistance Value:** 10 kΩ, 50 kΩ (depending on variant)  
- **Number of Taps:** 100  
- **Interface:** Up/Down (U/D) and Increment (INC)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The X9315WM is a non-volatile, digitally controlled potentiometer (XDCP) that emulates mechanical potentiometers.  
- It features 100 resistive positions, providing precise digital control over resistance settings.  
- The device retains its last setting even when power is removed, thanks to non-volatile EEPROM memory.  

### **Features:**
- **Non-Volatile Memory:** Saves wiper position during power-off.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Increment/Decrement Control:** Simple digital interface for adjusting resistance.  
- **End-to-End Resistance Tolerance:** ±20% (typical).  
- **Wiper Current:** 3 mA (max).  
- **High Reliability:** 100,000 data retention cycles.  

For exact resistance values and other specific details, refer to the datasheet for the exact variant (e.g., X9315WM10 for 10 kΩ, X9315WM50 for 50 kΩ).
