Description and Introduction

Wiper Position Stored in Non-volatile Memory and Recalled on Power-up The **X9C503SIZ** is a digitally controlled potentiometer (XDCP) manufactured by **Intersil** (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Digitally Controlled Potentiometer (XDCP)  
- **Resistance Value:** 50 kΩ  
- **Number of Taps:** 100  
- **Interface:** 3-Wire (Up/Down, Increment, and Chip Select)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Non-Volatile Memory:** Stores wiper position on power-down  
- **End-to-End Resistance Tolerance:** ±20%  
- **Low Power Consumption:** 3 mA (max) active current, 750 µA (max) standby current  
- **Package:** 8-Lead SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The **X9C503SIZ** is a solid-state potentiometer that replaces mechanical potentiometers in applications requiring digital control.  
- It provides 100 resistive steps with a wiper that can be adjusted via a simple up/down interface.  
- The non-volatile memory ensures the last wiper position is retained when power is removed.  

### **Features:**
- **Non-Volatile Wiper Storage:** Retains settings during power-off.  
- **100 Taps:** Provides fine resolution for adjustments.  
- **Low Power Operation:** Suitable for battery-powered applications.  
- **Simple Serial Interface:** Easy integration with microcontrollers.  
- **Endurance:** 100,000 data changes per bit.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.
