Description and Introduction

5 Volt, Byte Alterable E2PROM The X28HC64DMB-12 is a high-speed CMOS EEPROM manufactured by XICOR. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Memory Size:** 64Kb (8K x 8 bits)  
- **Technology:** High-speed CMOS  
- **Access Time:** 120ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Endurance:** 100,000 write cycles (minimum)  
- **Data Retention:** 100 years (minimum)  
- **Package:** 28-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The X28HC64DMB-12 is a non-volatile EEPROM with a byte-write capability.  
- It supports a simple two-wire serial interface for programming and reading operations.  
- Designed for high-speed applications with a fast access time of 120ns.  
- Features a write-protect pin for hardware data protection.  

### **Features:**  
- **Fast Read Access Time:** 120ns  
- **Low Power Consumption:**  
  - Active Read Current: 30mA (typical)  
  - Standby Current: 100μA (typical)  
- **Byte-Write Capability:** Allows individual byte programming without erasing the entire chip.  
- **Hardware Write Protection:** WP pin prevents accidental writes.  
- **Self-Timed Write Cycle:** Internal control for programming operations.  
- **High Reliability:**  
  - 100,000 write cycles endurance  
  - 100-year data retention  

This information is strictly based on the manufacturer's specifications for the X28HC64DMB-12 EEPROM.

Application Scenarios & Design Considerations

5 Volt, Byte Alterable E2PROM

Alternative Part Number

  • AT28C64B-15DM/883 --: Direct functional equivalent 64Kbit parallel EEPROM in a ceramic DIP, military temperature range, and 883 screening similar to the original X28HC64DMB-12.
  • M28C64C-15 --: 64Kbit parallel EEPROM with compatible pinout and access timing, usable as a drop-in replacement in most legacy X28HC64 designs.
  • NM28C64-15 --: Pin-compatible 64Kbit parallel EEPROM with comparable 150ns access time, suitable for older XICOR X28HC64 sockets.
