The Intersil X28C256D-25 is a 256K (32K x 8) Electrically Erasable PROM (EEPROM). The '-25' indicates a 250ns access time, and the 'D' likely denotes a specific package type or temperature range.

Applications

• Embedded systems requiring significant non-volatile memory for code and data storage.
• Industrial control systems for storing calibration parameters and program settings.
• Data logging applications where large amounts of data need to be retained.
• Communication equipment for storing configuration information.
• Applications requiring frequent reprogramming and reliable data retention.

Features

• 256K Bit Storage: Organized as 32K x 8 bits.
• Electrically Erasable: Supports in-system programming and reprogramming.
• Non-Volatile: Retains data even without power.
• 250ns Access Time: Provides reasonable data access speed.
• TTL Compatibility: Interfaces easily with TTL logic.
• Single 5V Supply: Operates with a single 5V power source.
• Automatic Page Write: Simplifies write operations.
• Data Polling: Allows verification of write cycle completion.

Benefits

• Large Storage Capacity: Suitable for applications with significant memory needs.
• In-System Programmability: Simplifies updates and modifications to stored data.
• Reliable Data Storage: Ensures data retention during power outages.
• Easy Integration: TTL compatibility streamlines system integration.
• Simplified Programming: Automatic page write reduces programming complexity.

Additional Details

The X28C256D-25's package type is likely indicated by the 'D' suffix.
