The X28C64DI-15 is a 64K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. (later acquired by Intersil, then Renesas). EEPROMs are non-volatile memory devices that can be electrically erased and reprogrammed, offering a flexible storage solution for applications requiring occasional updates to stored data.

Applications:

• Embedded systems
• Industrial control equipment
• Data logging
• Configuration storage
• Calibration data storage

Features:

• 64K (8K x 8) memory organization
• Non-volatile storage
• Electrically erasable and programmable
• Fast access time
• Low power consumption

Benefits:

• Data retention without power
• In-system reprogrammability
• Simplified system design
• Reduced power requirements
• Long-term reliability

Additional Details:

The X28C64DI-15 features an access time of 150ns. The device is typically packaged in a DIP (Dual In-line Package) for easy integration into through-hole circuit boards. EEPROMs are often used to store configuration parameters, calibration data, or other types of data that need to be retained even when power is removed. They offer a convenient way to update firmware or change settings without requiring physical replacement of memory chips. The DI in the part number usually signifies the package type, typically DIP. The 64K capacity allows for storing a significant amount of data in a relatively small footprint.
