Description and Introduction

Wiper Position Stored in Non-volatile Memory and Recalled on Power-up The **X9C503SZ** is a digitally controlled potentiometer (XDCP) manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Type:** 100-Tap Digitally Controlled Potentiometer (XDCP)  
- **Resistance Value:** 50 kΩ  
- **Tolerance:** ±20%  
- **End-to-End Resistance Temperature Coefficient:** 750 ppm/°C  
- **Wiper Resistance:** 40 Ω typical  
- **Supply Voltage Range:** 4.5V to 5.5V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC (Small Outline IC)  

### **Descriptions:**
- The **X9C503SZ** is a non-volatile, digitally controlled potentiometer that emulates mechanical potentiometers but is controlled via digital signals.  
- It provides **100 tap points** for precise resistance adjustment.  
- The wiper position is stored in non-volatile memory, retaining settings even when power is removed.  
- It is commonly used for calibration, trimming, and adjustable control in electronic circuits.  

### **Features:**
- **Non-Volatile Memory:** Saves wiper position during power-off.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Increment/Decrement Control Interface:** Simple 3-wire (CS, U/D, INC) digital control.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **Endurance:** 100,000 data changes per bit.  
- **Small Footprint:** Available in an 8-pin SOIC package.  

This device is widely used in applications such as **volume control, LCD contrast adjustment, and programmable voltage references**.
