Description and Introduction

CPU Supervisor with 4K SPI EEPROM The part **X5043PZ** is manufactured by **INTERSIL** (now part of Renesas Electronics). Below are the specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Type:** Serial EEPROM with a built-in microprocessor supervisor (voltage monitor)  
- **Memory Capacity:** 4Kbit (512 x 8)  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-lead PDIP (Plastic Dual In-line Package)  
- **Write Cycle Endurance:** 1,000,000 cycles  
- **Data Retention:** 100 years  

### **Descriptions:**  
- Combines a **4Kbit EEPROM** with a **voltage supervisor** for system monitoring.  
- Features a **watchdog timer**, **reset control**, and **brown-out detection** for improved system reliability.  
- Designed for **low-power** applications with a standby current of **10µA** (typical).  

### **Features:**  
- **Integrated Voltage Monitoring:** Resets the system when voltage drops below a threshold.  
- **Programmable Watchdog Timer:** Prevents system lock-up.  
- **SPI Interface:** Supports high-speed data transfer.  
- **Software & Hardware Write Protection:** Prevents accidental data corruption.  
- **Self-Timed Write Cycle:** No external delays required.  

This information is based on INTERSIL's documentation before its acquisition by Renesas. For exact details, refer to the official datasheet.
