Description and Introduction

5 Volt, Byte Alterable E2PROM The **X28HC64P-90** is a high-speed CMOS 64K (8K x 8) EEPROM manufactured by **INTESIL**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Memory Size:** 64Kbit (8K x 8)  
- **Access Time:** 90ns  
- **Operating Voltage:** 5V ±10%  
- **Technology:** High-speed CMOS  
- **Package Type:** 28-pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Endurance:** 100,000 write cycles (minimum)  
- **Data Retention:** 10 years (minimum)  

### **Descriptions:**  
- The **X28HC64P-90** is a non-volatile EEPROM with a byte-alterable architecture, allowing individual byte writes without requiring a full chip erase.  
- It features a fast read access time of **90ns**, making it suitable for high-performance applications.  
- The device supports a **5V-only** operation, simplifying system design.  

### **Features:**  
- **Fast Read Access Time:** 90ns  
- **Low Power Consumption:**  
  - Active current: 30mA (typical)  
  - Standby current: 100μA (typical)  
- **Byte-Write Capability:** Allows single-byte modification without block erase.  
- **Hardware & Software Data Protection:** Prevents accidental writes.  
- **CMOS Technology:** Ensures high noise immunity and low power consumption.  
- **JEDEC Standard Pinout:** Compatible with other industry-standard EEPROMs.  

This information is based solely on the manufacturer's specifications for the **X28HC64P-90** by **INTESIL**.

Application Scenarios & Design Considerations

5 Volt, Byte Alterable E2PROM

Alternative Part Number

  • AT28C64B-15PU --: 64Kbit parallel EEPROM in DIP-28, functionally equivalent to the X28HC64 with similar pinout and access timing; widely available and well documented.
  • M28C64-15N6 --: 64Kbit parallel EEPROM in DIP-28 package with comparable 150ns access time, suitable drop-in replacement for legacy 28HC64 designs.
  • NM28C64N-15 --: 64Kbit parallel EEPROM in DIP-28 with similar organization and timing, usable as an alternative when the original Intersil part is unavailable.
  • NM28C64-15 --: 64Kbit parallel EEPROM in 28-pin DIP package with comparable access time and interface, usable as an alternative when the original XICOR part is unavailable.
