Instructions for Use

1. Power Supply:

   • Connect VCC to the positive power supply (2.5V to 5.5V).
   • Connect GND to the ground.

2. SPI Interface:

   • SI (Serial In): Data input from the master device.
   • SO (Serial Out): Data output to the master device.
   • SCK (Clock): Clock signal from the master device.
   • CS (Chip Select): Active low signal to select the device.
   • WP (Write Protect): Active low signal to prevent writing to the device. Connect to VCC to disable write protection.
   • NC (No Connect): Leave unconnected.

3. Initialization:

   • Ensure CS is high (inactive) before starting any communication.
   • Bring CS low to initiate communication.

4. Reading Data:

   • Send the read command (0x03) followed by the address (2 bytes) of the data to be read.
   • The device will start sending data on the SO line.

5. Writing Data:

   • Send the write enable command (0x06) to allow writing.
   • Send the write command (0x02) followed by the address (2 bytes) and the data to be written.
   • Wait for the write cycle to complete (typically 5ms).

6. Status Check:

   • Send the read status register command (0x05) to check the status of the device.
   • The status register will indicate if the device is busy or if there are any errors.

7. Sector Erase:

   • Send the write enable command (0x06).
   • Send the sector erase command (0xD8) followed by the address of the sector to be erased.
   • Wait for the erase cycle to complete (typically 300ms).

8. Write Protection:

   • To enable write protection, bring the WP pin low.
   • To disable write protection, connect the WP pin to VCC.

9. Power Down:

   • Before powering down, ensure all operations are completed and the device is not busy.
   • Disconnect VCC and GND when the device is no longer needed.

Notes:

• Ensure proper decoupling capacitors are used near the VCC and GND pins to filter out noise.
• Avoid exceeding the maximum operating voltage and temperature ranges to prevent damage to the device.
