The X28C64DI-25 is a 64K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. (later acquired by Intersil and then Renesas). This memory device is designed for non-volatile data storage, meaning it retains its data even when power is removed. The '-25' indicates an access time of 250ns, making it suitable for a variety of applications where relatively fast read/write speeds are required.

Applications

• Embedded Systems: Used for storing configuration data, calibration parameters, and firmware in embedded systems.
• Industrial Control Systems: Employed for storing program code and data in programmable logic controllers (PLCs) and other industrial automation equipment.
• Data Logging: Utilized in data loggers for storing sensor data and other information over extended periods.
• Instrumentation: Found in test and measurement equipment for storing calibration data and instrument settings.
• BIOS Storage: Used in older computer systems for storing the Basic Input/Output System (BIOS) firmware.
