Description and Introduction

E 2 POT TM Nonvolatile Digital Potentiometer Part X9315WMI is a digital potentiometer manufactured by Intersil (now part of Renesas Electronics). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Digitally Controlled Potentiometer (XDCP™)  
- **Resistance Value:** 10 kΩ  
- **Number of Taps:** 100  
- **Interface:** Up/Down (U/D) and Increment (INC)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  
- **Non-Volatile Memory:** Yes (EEPROM stores wiper position)  
- **Wiper Current:** ±1 mA  
- **End-to-End Resistance Tolerance:** ±20%  
- **Low Power Consumption:** 3 µA (standby), 750 µA (active)  

### **Descriptions:**  
The X9315WMI is a solid-state, non-volatile digital potentiometer that emulates mechanical potentiometers. It provides a 100-position adjustable resistance divider via a simple up/down interface. The wiper position is stored in EEPROM, ensuring retention when power is removed.  

### **Features:**  
- **Non-Volatile Wiper Storage:** Retains settings during power-off.  
- **100 Tap Points:** Allows fine resolution adjustments.  
- **Wide Operating Voltage:** Compatible with 3V and 5V systems.  
- **Incremental Control Interface:** Simple two-wire (U/D and INC) control.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Solid-State Reliability:** No mechanical wear.  
- **End-to-End Resistance:** 10 kΩ with ±20% tolerance.
