Description and Introduction

5 Volt, Byte Alterable E2PROM The **X28HC64P-70** is a high-speed CMOS EEPROM manufactured by **INTESIL** (formerly **INTERSIL**). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

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

### **Descriptions:**  
- The **X28HC64P-70** is a **64Kbit Electrically Erasable PROM (EEPROM)** with a fast access time of **70ns**.  
- It is designed for applications requiring **high-speed read operations** and **non-volatile storage**.  
- The device supports **byte-level read and write operations**, making it suitable for firmware storage and parameter settings.  

### **Features:**  
- **Fast Read Access Time:** 70ns  
- **Low Power Consumption:**  
  - Active Current: 30mA (max)  
  - Standby Current: 100μA (max)  
- **Byte-Write and Page-Write Capability**  
- **Automatic Write Cycle Timing** with internal control  
- **Hardware and Software Data Protection**  
- **TTL-Compatible Inputs/Outputs**  
- **JEDEC Standard Pinout** for easy replacement  

This EEPROM is commonly used in embedded systems, industrial controls, and computing applications requiring reliable non-volatile memory.  

*(Note: INTESIL was later acquired by Renesas Electronics.)*
