Description and Introduction

CPU Supervisor with 9Kbit SPI EEPROM The part **X5083S8Z-2.7** is manufactured by **Intersil** (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Part Number:** X5083S8Z-2.7  
- **Manufacturer:** Intersil  
- **Package:** 8-lead SOIC  
- **Supply Voltage (VCC):** 2.7V to 5.5V  
- **Reset Threshold Voltage:** Adjustable or fixed (exact value depends on variant)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Reset Timeout Period:** Programmable or fixed (varies by model)  
- **Watchdog Timer:** Yes (timeout typically adjustable)  
- **Manual Reset Input:** Available (active-low)  

### **Descriptions:**  
- The **X5083S8Z-2.7** is a microprocessor supervisory circuit designed to monitor power supply voltages and provide reset signals to microprocessors or microcontrollers.  
- It integrates a watchdog timer, manual reset input, and voltage monitoring in a compact 8-lead SOIC package.  
- The device ensures proper system operation by asserting a reset signal when the supply voltage drops below a specified threshold.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC and triggers reset if voltage falls below the threshold.  
- **Watchdog Timer:** Prevents system lockup by requiring periodic toggling from the host.  
- **Manual Reset Input:** Allows external reset triggering via a pushbutton or logic signal.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Wide Operating Voltage Range:** Supports 2.7V to 5.5V systems.  
- **Industrial Temperature Range:** Operates reliably in harsh environments (-40°C to +85°C).  

For exact reset threshold values and programmable features, refer to the official datasheet from Intersil/Renesas.

Application Scenarios & Design Considerations

CPU Supervisor with 9Kbit SPI EEPROM

Alternative Part Number

  • CAT1025WI-30 --: Supervisory circuit with 2.7V/3.0V threshold and I2C serial EEPROM, functionally similar to the X5083 supervisor plus memory combination.
  • MAX6369KA-T --: Voltage supervisor with reset output in a small package, suitable replacement for supply monitoring in 2.7V systems.
  • MCP130-300DI/TO --: Low-cost 3.0V voltage supervisor with active-low reset, commonly used as a drop-in for Xicor supervisor parts.
  • CAT811STBI-GT3 --: Supervisory circuit with 2.7V-class threshold in an 8-pin package; widely available and functionally similar to the X5083 supervisor.
  • MAX803SQ308T1G --: Low-power microprocessor supervisor with 3.08V reset threshold, suitable replacement for supply monitoring in 2.7V systems.
  • TPS3808G27DBVR --: Adjustable-delay supervisor with 2.7V threshold option in SOT-23, offering a modern alternative with programmable reset delay.
