Instructions:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 2.7V to 3.6V.
   • Connect the Vcc pin to the power supply and the GND pin to ground.

2. Communication:

   • Use the SPI interface to communicate with the device.
   • Connect the following pins:
     • CS (Chip Select): Active low.
     • SCK (Serial Clock): Input clock signal.
     • SI (Serial Input): Data input.
     • SO (Serial Output): Data output.

3. Initialization:

   • Before performing any read or write operations, ensure the device is properly initialized by setting the CS pin low.
   • After initialization, set the CS pin high to end the command sequence.

4. Read Operations:

   • To read data, send the Read command (0x03) followed by the address of the memory location.
   • The device will then output the data from the specified address.

5. Write Operations:

   • To write data, first send the Write Enable command (0x06).
   • Then, send the Write command (0x02) followed by the address and the data to be written.
   • Wait for the Write In Progress (WIP) bit in the Status Register to clear before initiating another write operation.

6. Erase Operations:

   • To erase a sector, first send the Write Enable command (0x06).
   • Then, send the Sector Erase command (0xD8) followed by the address of the sector to be erased.
   • Wait for the WIP bit to clear before performing any other operations.

7. Status Register:

   • The status register can be read using the Read Status Register command (0x05).
   • The WIP bit indicates whether a write or erase operation is in progress.

8. Data Retention and Endurance:

   • Ensure that the device is stored and operated within the specified temperature ranges to maintain data retention and endurance.

9. Handling:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
