Description and Introduction

CPU Supervisor with 4K SPI EEPROM The part **X5043S8IZ-2.7A** is manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Memory Type:** EEPROM (Electrically Erasable Programmable Read-Only Memory)  
- **Memory Size:** 4Kbit (512 x 8)  
- **Package:** 8-lead SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The **X5043S8IZ-2.7A** is a **voltage supervisory circuit with EEPROM**, integrating a **power-on reset (POR)**, **brown-out reset (BOR)**, **watchdog timer**, and **serial EEPROM** in a single chip.  
- It is designed for **low-voltage applications** and ensures system reliability by monitoring power supply conditions.  
- The built-in **watchdog timer** helps recover from microcontroller lock-ups.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for brown-out and power failure conditions.  
- **Watchdog Timer:** Configurable timeout periods (200ms, 600ms, 1.4s, or disabled).  
- **Serial EEPROM:** 4Kbit (512 bytes) with **1 million write cycles** and **100-year data retention**.  
- **SPI Interface:** Supports standard SPI communication for easy integration.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Reset Output:** Active-low RESET signal for system initialization.  

This part is commonly used in **embedded systems, industrial controls, automotive electronics, and power management applications**.  

(Note: Since Intersil was acquired by Renesas, further documentation may be available under Renesas' product listings.)
