Description and Introduction

Serial E2PROM The part **X24042P** is manufactured by **XICOR**. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Serial EEPROM (Electrically Erasable Programmable Read-Only Memory)  
- **Memory Size:** 4 Kbit (512 x 8 bits)  
- **Interface:** I²C (2-wire serial interface)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Write Cycle Endurance:** 1,000,000 cycles  
- **Data Retention:** 100 years  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-pin PDIP, 8-pin SOIC  

### **Descriptions:**  
- The **X24042P** is a low-power CMOS serial EEPROM designed for reliable non-volatile data storage.  
- It supports byte-level and page-level write operations (up to 16 bytes per page).  
- Includes a built-in write protect feature via the **WP** pin for hardware data protection.  

### **Features:**  
- **Low Power Consumption:** Active current (3 mA max), standby current (10 µA max).  
- **Schmitt Trigger Inputs:** Noise filtering on SDA and SCL lines.  
- **Software Write Protection:** Configurable memory protection via I²C commands.  
- **Self-Timed Write Cycle:** Automatic erase and program cycles.  
- **Industrial-Grade Reliability:** High endurance and long data retention.  

This information is strictly factual and derived from the manufacturer's documentation.
