Instructions for Use:

1. Power Supply Connection: Connect VCC to the power supply within the specified voltage range (2.5V to 5.5V). Ensure GND is connected to ground.
2. SPI Interface Setup: The device uses an SPI interface for communication. Connect the pins as follows:
   • MOSI (Master Out Slave In)
   • MISO (Master In Slave Out)
   • SCK (Serial Clock)
   • CS (Chip Select)
3. Initialization: Before any read or write operations, ensure the chip select (CS) pin is low to activate the device.
4. Writing Data: To write data, send a WRITE command followed by the address and data bytes. Wait for the write cycle to complete (up to 5ms).
5. Reading Data: Send a READ command followed by the address. The data will be output on the MISO line.
6. Standby Mode: To reduce power consumption, place the device in standby mode by setting CS high when not in use.
7. Handling: Handle with care to avoid damage from electrostatic discharge (ESD). Follow standard ESD precautions.
