Description and Introduction

5 Volt, Byte Alterable E2PROM The X28C64SI-25 is a 64K (8K x 8) CMOS EEPROM manufactured by XICOR. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Organization:** 8K x 8 (64K bits)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 250 ns (max)  
- **Operating Current:** 30 mA (max)  
- **Standby Current:** 100 μA (max)  
- **Endurance:** 100,000 write cycles (min)  
- **Data Retention:** 100 years (min)  
- **Package:** 28-lead SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** Industrial (-40°C to +85°C)  

### **Descriptions:**  
- The X28C64SI-25 is a byte-alterable EEPROM with a fast read access time.  
- It supports a simple 3-wire interface for write operations (CE#, OE#, WE#).  
- Features a built-in software data protection mechanism to prevent accidental writes.  
- Compatible with JEDEC-standard pinout for easy replacement of EPROMs.  

### **Features:**  
- **Fast Read Access Time:** 250 ns maximum.  
- **Low Power Consumption:** Low standby current (100 μA max).  
- **Byte-Write Capability:** Allows individual byte modification.  
- **Software Data Protection (SDP):** Prevents inadvertent writes.  
- **High Reliability:** 100,000 write cycles and 100-year data retention.  
- **CMOS Technology:** Ensures low power and high noise immunity.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

This information is based solely on the manufacturer's datasheet for the X28C64SI-25.

Application Scenarios & Design Considerations

Alternative Part Number

  • AT28C64B-25SI --: Same 8K x 8 parallel EEPROM with 250 ns access time in a 28-pin SOIC package, pin-compatible and functionally equivalent.
  • M28C64-25N6 --: 64K-bit parallel EEPROM with 250 ns speed grade and compatible pinout, suitable direct replacement for the X28C64SI-25.
  • NM28C64-25 --: Equivalent 8K x 8 EEPROM with 250 ns access time and similar SOIC footprint, usable as a drop-in alternative.
  • M28C64-25SI --: 64Kbit parallel EEPROM with 250ns access time and compatible pinout, suitable drop-in replacement for legacy designs.
  • NM28C64-25SI --: 64Kbit parallel EEPROM offering 250ns access time and SOIC-28 footprint, usable as an alternative with timing verification.
