Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.7 V to 3.6 V).

2. Initialization:

   • Before performing any read/write operations, initialize the device according to the datasheet specifications.

3. Read Operation:

   • Apply a low signal to the Chip Select (CS) pin.
   • Provide the address on the address lines.
   • Read data from the data output pins.

4. Write Operation:

   • To write data, ensure that the Write Enable (WE) pin is activated.
   • Follow the page write procedure as specified in the datasheet.
   • Do not exceed the maximum number of write/erase cycles (1,000,000).

5. Erase Operation:

   • Perform sector or bulk erase commands as per the datasheet guidelines.
   • Verify the status register to ensure the operation is complete before proceeding with new commands.

6. Temperature Considerations:

   • Operate within the temperature range (-40°C to +85°C) to avoid damage and ensure reliable performance.

7. Handling Precautions:

   • Handle the device with care to prevent electrostatic discharge (ESD) damage.
   • Store in an ESD-safe environment when not in use.

8. Software Write Protect:

   • Utilize the software write protect feature to prevent accidental writes or erases.
