The Xicor X2864BD25 is a 64K (8K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory). It's designed for applications requiring non-volatile storage and in-system reprogrammability.

Applications:

• Data Logging Systems
• Industrial Control Equipment
• Embedded Systems for storing configuration data
• Robotics
• Instrumentation
• Medical Devices

Features:

• Fast Access Time: 250ns
• Low Power CMOS Technology
• Automatic Page Write Operation
• Data Polling for End of Write Detection
• TTL Compatible Inputs and Outputs
• Self-Timed Write Cycle
• Endurance: Minimum 10,000 Write Cycles
• Data Retention: 10 Years

Benefits:

• Reliable Non-Volatile Data Storage: Ensures data is retained even when power is removed, critical for system reliability.
• In-System Reprogrammability: Allows for easy updates and modifications to stored data without removing the device from the system.
• Fast Write Times: Reduces write cycle times, improving system performance.
• Low Power Consumption: Minimizes power consumption, making it suitable for battery-powered applications.
• Easy Integration: TTL compatible inputs and outputs simplify interfacing with other system components.

Additional Details:

The X2864BD25 utilizes a CMOS process for low power consumption and high performance. The automatic page write feature allows for efficient writing of data blocks. Data polling provides a simple method to determine the end of the write cycle, allowing the system to proceed with other tasks. The device is typically available in a 28-pin DIP (Dual In-line Package).

This EEPROM is often employed in applications where firmware updates or configuration settings need to be stored persistently and updated occasionally. Its ease of use and reliable performance make it a popular choice for embedded systems developers.
