Notes:
1. Permanent device damage may occur if the absolute maximum ratings are exceeded. Functional operation should be
restricted to the conditions as specified in the operational sections of this data sheet. Exposure beyond recommended
operating conditions for extended periods may affect device reliability.
2. The Si4720/21 devices are high-performance RF integrated circuits with certain pins having an ESD rating of < 2 kV
HBM. Handling and assembly of these devices should only be done at ESD-protected workstations.
3. For input pins SCLK, SEN, SDIO, RST, RCLK, GPO1, GPO2/INT, and GPO3.
4. At RF input pin FMI.
