2. Serial Clock (CLK): Provides the clock signal for data transfer.
3. Serial Data Input (DI): Receives data from the external device.
4. Serial Data Output (DO): Transmits data to the external device.
5. Write Protect (/WP): Used to protect the chip from accidental writes.
6. Hold (/HOLD): Pauses ongoing operations without resetting the chip.
7. Ground (GND): Connected to the ground reference of the system.
8. Power Supply (VCC): Connected to the power source (2.7V - 3.6V).

Functional Features

• Sector Erase and Program: Allows for selective erasure and programming of memory sectors.
• Block Erase and Program: Enables erasure and programming of larger memory blocks.
• Chip Erase: Clears the entire memory content in one operation.
