Instructions for Use:

1. Power Supply:

   • Connect Vcc to a stable power supply between 2.7V and 3.6V.
   • Connect Vss to ground.

2. Chip Select (/CS):

   • Low active signal to select the device.
   • Must be held low during all operations.

3. Serial Clock (SCK):

   • Provides the clock signal for data transfer.
   • Maximum frequency is 50 MHz.

4. Serial Input (SI):

   • Data input pin for commands and data.

5. Serial Output (SO):

   • Data output pin for read operations.

6. Write Protect (/WP):

   • High to disable write operations.
   • Low to enable write operations.

7. Hold (/HOLD):

   • High to allow normal operation.
   • Low to pause ongoing operations.

8. Initialization:

   • Ensure /CS is high before sending any commands.
   • Bring /CS low to start communication.

9. Command Sequence:

   • Send the appropriate command code followed by any required address or data bytes.
   • Refer to the device datasheet for specific command codes and sequences.

10. Read Operation:

    • Send the read command followed by the starting address.
    • Data will be available on the SO pin after the access time.

11. Write Operation:

    • Send the write enable command.
    • Send the page program command followed by the starting address and data bytes.
    • Wait for the write cycle to complete.

12. Erase Operation:

    • Send the write enable command.
    • Send the sector or bulk erase command.
    • Wait for the erase cycle to complete.

13. Power Down:

    • Ensure all operations are completed before powering down.
    • Disconnect Vcc from the power supply.

14. Storage:

    • Store in a dry, cool place when not in use.
    • Avoid exposure to extreme temperatures and humidity.
