Instructions for Use:

1. Power Supply: Ensure the power supply voltage is within the specified range of 3.0V to 3.6V.
2. Installation: Carefully insert the component into the socket or solder it onto the PCB ensuring correct orientation as indicated by the pin 1 marker.
3. Signal Integrity: Keep signal traces short and direct to minimize noise and ensure reliable operation.
4. Power Down: Utilize the power-down mode to reduce power consumption when not in active use.
5. Handling: Handle with care to avoid damage to the pins; follow ESD (Electrostatic Discharge) precautions.
6. Testing: After installation, perform a thorough test to ensure all parameters meet the specifications.
7. Storage: Store in an environment that does not exceed the temperature limits to preserve data retention properties.
