Description and Introduction

CPU Supervisor with 16Kbit SPI EEPROM Description **Part X5165S8I Manufacturer: INTERSIL**  

### **Specifications:**  
- **Manufacturer:** Intersil (now part of Renesas Electronics)  
- **Part Number:** X5165S8I  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Type:** Digital Potentiometer (Digitally Programmable Potentiometer)  
- **Interface:** Serial (SPI-compatible)  
- **Resolution:** 256 taps  
- **Resistance Range:** 10kΩ  
- **Operating Voltage:** 2.7V to 5.5V  
- **Temperature Range:** Industrial (-40°C to +85°C)  
- **Non-Volatile Memory:** Yes (retains settings during power-off)  
- **Wiper Current:** ±1mA (max)  

### **Descriptions and Features:**  
- The **X5165S8I** is a digitally controlled potentiometer (DCP) that replaces mechanical potentiometers.  
- It features a **SPI-compatible serial interface** for digital control of resistance settings.  
- **Non-volatile memory** allows the device to retain its last setting even when powered off.  
- **256-tap resolution** provides fine adjustment capability.  
- Suitable for applications requiring **programmable voltage dividers, calibration, or signal conditioning**.  
- **Low power consumption** and **wide operating voltage range** make it ideal for battery-powered systems.  
- **Industrial temperature range** ensures reliable performance in harsh environments.  

This part is commonly used in **audio equipment, instrumentation, and industrial control systems** where precise resistance adjustments are needed.  

(Note: Always verify datasheet details for the latest specifications.)

Application Scenarios & Design Considerations

Alternative Part Number

  • DS1232LPS-2+ --: Supervisor IC with reset and watchdog functions in an 8-pin SOIC package, functionally similar to the X5165 and pin-compatible in most designs.
  • CAT1161WI-25 --: CPU supervisor with EEPROM and watchdog in an 8-pin SOIC, offering comparable supply monitoring and reset features.
  • M41ST85WMH6F --: Supervisor with watchdog and serial EEPROM in an SOIC package, suitable as a functional replacement for the X5165S8I.
  • ISL88731 --: Same vendor lineage as the original Intersil part; CPU voltage monitor/supervisor with similar function and SOIC-8 package, making it a natural drop-in candidate.
  • MAX16054 --: Voltage supervisor with watchdog and manual reset in an 8-pin package, functionally comparable to the X5165 supervisor family.
  • CAT1161 --: Low-cost 8-pin voltage supervisor with watchdog and reset, widely available and electrically similar to the X5165.
