The Intersil X28256DI-25 is a 256K (32K x 8) Electrically Erasable PROM (EEPROM). This memory device provides a larger storage capacity than its 16K counterpart, offering more space for data logging, firmware storage, and configuration settings in embedded applications. The '-25' indicates the access time, in this case, 250ns.

Applications

• Advanced microcontroller-based systems requiring substantial non-volatile memory.
• Data logging applications with extensive data storage requirements.
• Industrial control systems storing complex calibration data and program instructions.
• Embedded systems necessitating large firmware images and configuration parameters.
• High-end PLCs with extensive program storage needs.

Features

• Larger Storage Capacity: 256K bit (32K x 8) organization provides ample storage space.
• Electrically Erasable: Enables in-system reprogramming and data updates.
• Non-Volatile: Retains data even when power is removed.
• TTL Compatibility: Interfaces seamlessly with standard TTL logic.
• Single 5V Supply: Operates with a single 5V power supply.
• Automatic Page Write: Simplifies write operations.
• Data Polling for End-of-Write Detection: Facilitates efficient write cycle management.
• Access Time: 250ns access time for relatively quick data retrieval.
