The X2864BP25 is a 64K EEPROM (Electrically Erasable Programmable Read-Only Memory) chip manufactured by Xicor Inc. This EEPROM chip is designed for non-volatile storage, allowing data to be retained even when power is removed. The "P25" likely refers to a speed grade, such as 250ns access time, though this is unconfirmed.

Applications

• Embedded Systems: Used for storing configuration data, firmware, and calibration parameters.
• Industrial Control Systems: Employed in PLCs (Programmable Logic Controllers) and other industrial equipment for storing program code and data.
• Instrumentation: Integrated into test and measurement equipment for storing calibration data and settings.
• Automotive Electronics: Used in engine control units (ECUs) and other automotive systems for storing configuration data and parameters.
• Consumer Electronics: Utilized in appliances, remote controls, and other consumer devices for storing settings and preferences.

Features

• 64K Memory Capacity: Provides 65,536 bits of non-volatile storage.
• Electrically Erasable: Can be erased and reprogrammed electrically, allowing for in-system updates.
• Non-Volatile: Retains data even when power is removed.
• Fast Access Time: Offers a fast access time for quick data retrieval.
• Page Write Mode: Supports page write mode for faster programming.
• Low Power Consumption: Designed for low power operation to minimize energy usage.

Benefits

• Non-Volatile Storage: Retains data even when power is off, ensuring data integrity.
• In-System Reprogrammability: Allows for easy updates and modifications without removing the chip from the system.
• Fast Access Time: Enables quick data retrieval, improving system performance.
