Instructions for Use

1. Power Supply Connection: Connect the VCC pin to a power supply within the operating voltage range (1.7V to 3.6V). Ensure the GND pin is connected to ground.

2. Serial Communication Setup:

   • Connect the SI (Serial Input), SCK (Serial Clock), and CS (Chip Select) pins to your microcontroller or host system.
   • The SO (Serial Output) pin should be connected to receive data from the device.

3. Initialization:

   • Before any command execution, ensure that the CS pin is set high. To start communication, bring the CS pin low.

4. Command Execution:

   • Send commands and addresses through the SI pin while toggling the SCK pin.
   • Data can be read from the SO pin after sending the appropriate read commands.

5. Programming and Erasing:

   • For writing data, use the Page Program command. Ensure that the write enable latch (WEL) is set before programming.
   • For erasing, use the Sector Erase, Bulk Erase, or Chip Erase commands as needed.

6. Status Check:

   • After issuing write or erase commands, check the status register to confirm completion by polling the Write In Progress (WIP) bit.

7. Power Down Mode:

   • To enter low-power mode, keep the CS pin high when not performing any operations.

8. Handling Precautions:

   • Avoid exceeding the maximum ratings specified in the datasheet.
   • Ensure proper handling to prevent electrostatic discharge (ESD) damage.
