Instructions for Use

1. Power Supply:

   • Connect Vcc to the positive supply voltage (2.5V to 5.5V).
   • Connect Vss to ground.

2. Communication:

   • Use the SPI interface for communication.
   • Ensure the SCK, MOSI, and MISO pins are connected to the corresponding pins on the master device.
   • The CS pin must be pulled low to select the device for communication.
   • The HOLD pin can be used to pause ongoing operations by pulling it low.
   • The WP pin can be used to enable write protection by pulling it high.

3. Initialization:

   • Before performing any read or write operations, ensure the device is selected by pulling the CS pin low.
   • Initialize the SPI communication with the appropriate clock speed (up to 10 MHz).

4. Read Operation:

   • Send the READ command (0x03) followed by the address of the data to be read.
   • The device will then output the data on the MISO line.

5. Write Operation:

   • Send the WRITE ENABLE command (0x06) to allow writing.
   • Send the WRITE command (0x02) followed by the address and the data to be written.
   • Wait for the write cycle to complete (up to 5 ms).

6. Status Register:

   • Use the READ STATUS REGISTER command (0x05) to read the status register.
   • Use the WRITE STATUS REGISTER command (0x01) to modify the status register.

7. Write Protection:

   • Set the WP pin high to prevent any write operations.
   • Clear the WP bit in the status register to enable writing.

8. Power Management:

   • To reduce power consumption, place the device in standby mode by ensuring the CS pin is high.
   • The device automatically enters standby mode when not selected.

9. Handling:

   • Handle the device with care to avoid static damage.
   • Store the device within the specified storage temperature range to ensure long-term reliability.
