Instructions for Use:

1. Power Supply:

   • Connect Vcc to the positive power supply (2.7V to 5.5V).
   • Connect GND to the ground.

2. Programming:

   • Apply Vpp (Vcc + 12.5V max) to the programming pin (pin 28) during write operations.
   • Use the appropriate programming algorithm to write data to the memory. Each write cycle takes a maximum of 9 ms.

3. Reading Data:

   • Apply the address to the address lines (A0-A15).
   • Assert the chip enable (CE#) and output enable (OE#) pins low to read data from the memory.
   • The data will be available on the data lines (D0-D7) after the access time (150 ns).

4. Erasing:

   • Expose the device to UV light for at least 20 minutes to erase the entire memory array.

5. Handling:

   • Handle the device with care to avoid static damage.
   • Store the device in a protective bag when not in use to prevent exposure to moisture.

6. Storage:

   • Store the device in a dry environment to ensure long-term reliability.

7. Temperature Considerations:

   • Ensure that the operating temperature remains within the specified range (-40°C to +85°C) to maintain optimal performance and data integrity.

8. Endurance and Data Retention:

   • The device is rated for 100,000 write/erase cycles and can retain data for up to 10 years at room temperature.
