Description and Introduction

CPU Supervisor with 16K EEPROM Part X4163 is manufactured by XICOR. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Nonvolatile Digital Potentiometer  
- **Interface:** I²C (2-wire serial interface)  
- **Resolution:** 256 taps (8-bit)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Endurance:** 100,000 write cycles per bit  
- **Data Retention:** 100 years  

### **Descriptions:**  
- The X4163 is a digitally controlled potentiometer (digipot) that provides nonvolatile memory storage for wiper settings.  
- It is designed for applications requiring precision adjustments, such as calibration, offset trimming, and signal conditioning.  
- The device retains its settings even when power is removed, ensuring consistent performance upon power-up.  

### **Features:**  
- **Nonvolatile Memory:** Saves wiper position during power-off.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **I²C Interface:** Allows easy integration with microcontrollers.  
- **Wide Voltage Range:** Supports both 3.3V and 5V systems.  
- **High Reliability:** Long data retention and endurance.  

For detailed electrical characteristics and pin configurations, refer to the official XICOR datasheet.

Application Scenarios & Design Considerations

CPU Supervisor with 16K EEPROM

Alternative Part Number

  • ISL4163 --: Intersil's ISL4163 is a direct functional equivalent to the Xicor X4163, offering the same CPU supervisor and EEPROM functionality with compatible pinout and voltage monitoring features.
  • CAT1163 --: The CAT1163 from ON Semiconductor provides similar CPU supervisory functions with integrated EEPROM, serving as a viable replacement for the X4163 in most applications.
  • DS1232 --: The DS1232 is a widely available microprocessor supervisory circuit that can substitute the X4163's reset and watchdog functions, though external EEPROM may be needed for full equivalence.
