The X28C64D-25 is a 64K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. This non-volatile memory device is designed for applications requiring in-system programmability and long-term data storage. It is frequently used in embedded systems, data logging, and configuration storage applications.

Applications:

• Embedded systems
• Data logging
• Configuration storage
• Firmware storage
• Programmable logic controllers (PLCs)

Features:

• 64K (8K x 8) memory organization
• Fast access time: 250ns
• In-system programmability
• Automatic page write operation
• Data polling for end-of-write detection
• Low power consumption

Benefits:

• Flexible Data Storage: The EEPROM technology allows for easy updating and modification of stored data in-system.
• Non-Volatile Memory: Data is retained even when power is removed, ensuring long-term storage of critical information.
• Simplified Programming: Automatic page write operation simplifies the programming process and reduces write times.
• Reliable Operation: Data polling provides a reliable method for detecting the completion of write operations.

Specifications:

The X28C64D-25 operates from a single 5V power supply. It features a typical write cycle time of 10ms and offers a data retention capability of greater than 10 years. The device is available in a 28-pin DIP or SOIC package. The operating temperature range is typically from 0°C to 70°C. This EEPROM is designed for high endurance and reliability, making it suitable for critical data storage applications.
