Instructions for Use:

1. Power Supply Connection:

   • Connect the Vcc pin to a power supply within the specified range (1.6V to 3.6V).
   • Ensure the GND pin is connected to ground.

2. Communication Setup:

   • The device uses SPI protocol for data transfer.
   • Connect the following pins to your microcontroller or SPI master device:
     • MOSI (Master Out Slave In)
     • MISO (Master In Slave Out)
     • SCK (Serial Clock)
     • CS (Chip Select)

3. Initialization:

   • Before performing any read/write operations, ensure the device is properly initialized by setting the CS pin low to select the device.

4. Read/Write Operations:

   • For write operations, send the appropriate command followed by the address and data bytes.
   • For read operations, send the read command and address, then clock out the data from the MISO line.

5. Standby Mode:

   • To enter standby mode, set the CS pin high, which minimizes current consumption.

6. Handling Precautions:

   • Avoid exceeding the maximum operating temperature to ensure data retention.
   • Ensure stable power supply and proper grounding to prevent data corruption.

7. Storage:

   • Store in a dry environment away from direct sunlight and extreme temperatures to maintain reliability.
