Instructions for Use

1. Power Supply:

   • Ensure the operating voltage (Vcc) is within the range of 4.5V to 5.5V.
   • The programming voltage (Vpp) should be set to 12.5V ± 0.5V.

2. Programming:

   • Apply the programming voltage (Vpp) to the appropriate pin.
   • Write data to the desired address using the standard write cycle.
   • The typical programming time is 2 ms.

3. Erase:

   • Expose the device to UV light for approximately 10 seconds to erase the contents.
   • Ensure the device is not exposed to UV light when not being erased to prevent accidental data loss.

4. Read Operation:

   • Apply the operating voltage (Vcc).
   • Select the desired address and read the data from the output pins.
   • The typical access time is 120 ns.

5. Handling:

   • Handle the device with care to avoid static discharge.
   • Store the device in a dry environment to prevent moisture damage.

6. Environmental Considerations:

   • Operate the device within the specified temperature range (-40°C to +85°C).
   • Store the device within the storage temperature range (-65°C to +150°C).

7. Data Retention:

   • The device retains data for up to 10 years under normal operating conditions.

8. Endurance:

   • The device can withstand up to 1,000 write/erase cycles.
