1. CS (Chip Select): Enables or disables device operation.
2. SCK (Serial Clock): Provides the clock signal for data transfers.
3. SI (Serial Input)/MOSI (Master Out Slave In): Receives data from the host controller.
4. SO (Serial Output)/MISO (Master In Slave Out): Sends data to the host controller.
5. WP (Write Protect): Provides hardware write protection for the status register.
6. VCC: Power supply pin.
7. GND: Ground reference.
8. HOLD: Pauses serial communication without deselecting the device.
These pins collectively facilitate read, write, and erase operations as per the SPI (Serial Peripheral Interface) protocol.
