Description and Introduction

5 Volt, Byte Alterable E2PROM The **X28HC64JI-90** is a high-speed CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **Xicor** (now part of Intersil). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 64 Kbit (8 K x 8 bits)  
- **Access Time:** 90 ns  
- **Operating Voltage:** 5V ±10%  
- **Technology:** High-speed CMOS  
- **Endurance:** 100,000 write cycles (minimum)  
- **Data Retention:** 100 years (minimum)  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:**  
  - Industrial: -40°C to +85°C  

### **Descriptions:**
- The **X28HC64JI-90** is a high-performance EEPROM designed for fast read and write operations.  
- It features a **byte-alterable** architecture, allowing individual bytes to be erased and reprogrammed without requiring a full chip erase.  
- The device is compatible with standard microprocessor interfaces and operates with a single 5V power supply.  

### **Features:**
- **High-Speed Performance:** 90 ns access time for fast read operations.  
- **Low Power Consumption:** CMOS technology ensures low standby and active power.  
- **Hardware & Software Protection:** Includes write protection features to prevent accidental data corruption.  
- **Self-Timed Write Cycle:** Internal circuitry controls programming timing, eliminating the need for external timing components.  
- **JEDEC Standard Pinout:** Ensures compatibility with industry-standard memory sockets.  
- **Reliable Data Retention:** Guaranteed data retention for 100 years.  

This EEPROM is commonly used in embedded systems, industrial controls, telecommunications, and other applications requiring non-volatile memory storage.  

(Note: Xicor was acquired by Intersil, which was later acquired by Renesas Electronics.)
