Description and Introduction

CPU Supervisor with 4kbit EEPROM **Part X4043 Manufacturer: XICOR**  

### **Specifications:**  
- **Type:** Non-Volatile Digital Potentiometer  
- **Interface:** Serial (SPI-compatible)  
- **Resolution:** 8-bit (256 taps)  
- **Memory Type:** EEPROM (Electrically Erasable Programmable Read-Only Memory)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Endurance:** 100,000 write cycles  
- **Data Retention:** 100 years  

### **Descriptions:**  
- The X4043 is a digitally controlled potentiometer (XDCP™) with non-volatile memory.  
- It provides a resistor divider network that can be adjusted via a serial interface.  
- The wiper position is stored in EEPROM, ensuring settings are retained when power is removed.  

### **Features:**  
- **Non-volatile storage** of wiper position  
- **SPI-compatible serial interface** for easy microcontroller communication  
- **Low power consumption**  
- **Small package options** (e.g., SOIC, TSSOP)  
- **Incremental/decremental control** for adjustments  
- **Wide operating voltage range** (2.7V–5.5V)  

This part is commonly used in applications requiring programmable resistance, such as calibration, volume control, and system tuning.
