Description and Introduction

LOW POWER CMOS EEPROM with hi-speed page write capability 256K EEPROM The X28HC256PM-12 is a high-speed CMOS EEPROM manufactured by XICOR. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 32K x 8 (256Kbit)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 120ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin PDIP (Plastic Dual In-line Package)  
- **Endurance:** 100,000 write cycles per byte  
- **Data Retention:** 100 years  
- **Interface:** Parallel  

### **Descriptions:**
- The X28HC256PM-12 is a high-performance Electrically Erasable Programmable Read-Only Memory (EEPROM).  
- It features a fast read access time of 120ns, making it suitable for high-speed applications.  
- The device supports both industrial and commercial temperature ranges.  
- It is designed for reliable non-volatile data storage with high endurance and long-term retention.  

### **Features:**
- **High-Speed Operation:** 120ns access time.  
- **Low Power Consumption:** Active current of 30mA (max), standby current of 100µA (max).  
- **Byte-Write Capability:** Allows individual byte modification without erasing the entire chip.  
- **Hardware & Software Data Protection:** Includes write protection features to prevent accidental data corruption.  
- **CMOS Technology:** Ensures low power and high noise immunity.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Self-Timed Write Cycle:** Simplifies system design by eliminating external timing requirements.  

This information is based solely on the manufacturer's specifications for the X28HC256PM-12.

Application Scenarios & Design Considerations
