The Intersil X2864AP-25 is a 64K (8K x 8) Electrically Erasable PROM (EEPROM) designed for non-volatile memory applications. The 'AP' likely denotes a specific package type (e.g., DIP) and possibly a standard temperature range. The '-25' signifies an access time of 250ns.

Applications

• Microcontroller-based systems for storing program code and configuration parameters.
• Data logging applications where non-volatile storage is required.
• Industrial control systems for storing calibration data and machine settings.
• Embedded systems requiring non-volatile memory for firmware and application data.
• Instrumentation and measurement equipment for storing calibration coefficients.

Features

• 64K Bit Storage: Organized as 8K x 8 bits.
• Electrically Erasable: Allows for in-system programming and reprogramming.
• Non-Volatile: Retains data even when power is removed.
• 250ns Access Time: Provides a moderate speed for data access.
• TTL Compatibility: Interfaces easily with TTL logic.
• Single 5V Supply: Operates with a single 5V power supply.
• Automatic Page Write: Simplifies the write process.
• Data Polling: Allows for checking the completion of write operations.

Benefits

• Reliable Data Storage: Ensures data retention in the absence of power.
• In-System Programmability: Facilitates easy updates and modifications.
• Easy Integration: TTL compatibility simplifies integration with existing systems.
• Cost-Effective: Provides a reliable non-volatile memory solution at a reasonable cost.
• Simplified Write Operations: Automatic page write eases programming efforts.

Additional Details

The X2864AP-25 is typically available in a DIP (Dual In-line Package), making it suitable for breadboarding and prototyping. It is crucial to consult the datasheet for the precise operating temperature range, write/erase cycle endurance, and other critical specifications. The datasheet will also confirm the exact meaning of the 'AP' designation regarding package type and any specific operating characteristics.
