Description and Introduction

CPU Supervisor with 8Kbit SPI EEPROM The part **X5083S8I** is a microprocessor supervisory circuit manufactured by **Intersil** (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Package:** 8-Lead SOIC (S8)  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable or fixed (typically 200ms)  
- **Watchdog Timer:** Programmable timeout period (1.6s default)  
- **Manual Reset Input:** Supports push-button reset  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The **X5083S8I** is a low-power supervisory circuit designed to monitor power supply voltages in microprocessor-based systems.  
- It provides reset signals to the processor during power-up, power-down, or brownout conditions.  
- The watchdog timer ensures system reliability by triggering a reset if the software fails to respond within a set time.  
- The manual reset input allows for user-initiated system resets.  

### **Features:**
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Adjustable Reset Threshold:** Can be configured for different voltage levels.  
- **Watchdog Timer:** Prevents system lockup by resetting the processor if software fails to toggle the watchdog input.  
- **Low Power Consumption:** Minimizes power draw in battery-operated applications.  
- **Manual Reset Capability:** External reset button support.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official Intersil (Renesas) datasheet.

Application Scenarios & Design Considerations

CPU Supervisor with 8Kbit SPI EEPROM

Alternative Part Number

  • CAT1161WI-25 --: Supervisory circuit with I2C EEPROM in an 8-pin SOIC package, functionally similar to the X5083S8I and widely available.
  • M41ST85WMH6F --: Combines supervisor, watchdog and serial EEPROM in SOIC-8, offering comparable system monitoring functions.
  • DS1780S --: System monitor IC in SOIC-8 with reset and watchdog features, suitable as a functional substitute.
  • DS17885S-5 --: Supervisor with nonvolatile memory and reset functions in an SOIC package, a practical substitute for the X5083S8I.
