The X28C64PI-25 is a 64K CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Intersil (now Renesas). It is a non-volatile memory device that can be electrically erased and reprogrammed, making it suitable for applications where data needs to be updated frequently without requiring physical removal of the chip.

Applications:

• Data Logging: Used in systems that require recording data over time, such as environmental monitoring or industrial control.
• Programmable Logic Controllers (PLCs): Stores configuration data and control programs.
• Embedded Systems: Stores firmware and configuration settings in devices like industrial controllers, medical devices, and consumer electronics.
• Robotics: Used for storing robot control programs and parameters.
• Automotive Electronics: Stores calibration data and system parameters in engine control units (ECUs) and other automotive systems.

Features:

• 64Kbit (8K x 8) Organization: Provides a storage capacity of 64 kilobits, organized as 8192 bytes of 8 bits each.
• Fast Access Time: Offers a typical access time of 250ns, enabling quick read operations.
• Low Power Consumption: CMOS technology ensures low power dissipation, making it suitable for battery-powered applications.
• Electrically Erasable and Programmable: Can be erased and reprogrammed electrically, allowing for in-system updates.
• Page Mode Write: Supports page mode write operations, allowing for faster programming of multiple bytes.
• Data Retention: Retains data for extended periods even when power is removed.
• JEDEC Standard Pinout: Adheres to the JEDEC standard pinout for easy integration into existing systems.
• Endurance: Offers a specified number of erase/write cycles, ensuring reliability over the product's lifespan.
