The E28F400B5T60 is a 4-Mbit (512K x 8) Flash Memory device manufactured by Intel. This NOR Flash memory provides fast read access times and in-system programmability, making it suitable for embedded systems requiring non-volatile storage for code and data. Being an end-of-life (EOL) product, it is primarily used in legacy systems or for maintaining existing designs where a direct replacement is needed.

Applications:

• Embedded Systems: Used to store firmware, boot code, and application data in embedded systems.
• Industrial Control Systems: Retains critical operational parameters and control algorithms.
• Networking Equipment: Stores configuration settings and boot loaders in older networking devices.
• Aerospace and Defense: Used in specific legacy systems for program storage.

Features:

• NOR Flash Technology: Provides fast random read access times, ideal for executing code directly from memory.
• 4-Mbit Capacity: Offers 4 Megabits (512 Kilobytes) of non-volatile storage.
• Top Boot Block: Features a boot block at the top of the memory map, simplifying system startup.
• In-System Programmability: Supports programming and erasing while the device is in the system, allowing for easy firmware updates.

Benefits:

• Fast Code Execution: Enables rapid execution of code directly from flash memory.
• Flexible Programming: Allows for convenient firmware updates without removing the device from the system.
• Non-Volatile Storage: Retains data even when power is removed, ensuring data integrity.

Additional Details:

The E28F400B5T60 has a typical access time of 60ns. It operates on a single 5V power supply. It supports various programming algorithms for writing and erasing data. Due to its end-of-life status, consider alternative flash memory solutions for new designs.
