Instructions for Use:

1. Power Supply Requirements:

   • Ensure the device is powered within the specified voltage range of 4.5V to 5.5V for reliable operation.

2. Programming Voltage:

   • Apply a programming voltage (VPP) between 12.0V and 13.5V during write operations.

3. Timing Considerations:

   • The access time is 200ns; ensure that all read/write operations are synchronized accordingly to prevent data corruption.

4. Temperature Range:

   • The device is designed to operate within an industrial temperature range of -55°C to +125°C. Avoid operating outside these limits to maintain performance and reliability.

5. Handling Precautions:

   • This device is sensitive to electrostatic discharge (ESD). Handle with care using appropriate ESD protection measures.

6. UV Erasure:

   • For erasing the contents, expose the device to ultraviolet light through the transparent window on the package. Ensure adequate exposure time as specified in the datasheet.

7. Installation:

   • Insert the device into a 28-pin socket or solder it onto the PCB ensuring correct orientation and pin alignment.

8. Testing:

   • After installation, verify the functionality by performing read/write tests to ensure proper operation.
