Instructions for FM25V05-GTR:

1. Power Supply Requirements:

   • Ensure the operating voltage is within the specified range (1.8V to 3.6V).

2. Initialization:

   • Before performing any read or write operations, initialize the device using the appropriate SPI commands.

3. Reading Data:

   • Use the SPI protocol to send a read command followed by the address from which data should be read.
   • Clock out the necessary number of bits to receive the data.

4. Writing Data:

   • Send a write enable command before initiating a write operation.
   • Follow with the write command and the address where data should be written.
   • Finally, send the data to be written.

5. Data Integrity:

   • To ensure data integrity, use the status register to check if the device is ready for new commands after each operation.

6. Handling Power Loss:

   • Implement proper power management techniques to prevent data corruption during unexpected power loss.

7. Temperature Considerations:

   • Operate the device within the specified temperature range (-40°C to +85°C) to ensure reliable performance.

8. Endurance Monitoring:

   • Monitor the number of write cycles to avoid exceeding the endurance limit of 1,000,000 cycles.

9. Storage Conditions:

   • When not in use, store the device in a dry, cool place to maintain its long-term reliability.
