Notes:
1. Permanent device damage may occur if the above 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 Si4702/03-D30 device is a high-performance RF integrated circuit with an ESD rating of < 2 kV HBM. Handling
and assembly of this device should only be done at ESD-protected workstations.
3. For input pins SCLK, SEN
, SDIO, RST, RCLK, GPIO1, GPIO2, and GPIO3.
4. At RF input pins.

Notes:
1. When selecting 2-wire Mode, the user must ensure that a 2-wire start condition (falling edge of SDIO while SCLK is
high) does not occur within 300 ns before the rising edge of RST
.
2. When selecting 3-wire Mode, the user must ensure that a rising edge of SCLK does not occur within 300 ns before the
rising edge of RST
.
3. When selecting 2-wire mode, the user must ensure that SCLK is high during the rising edge of RST
, and stays high
until after the 1st start condition.
4. If GPIO3 is driven low by the user, then minimum t
GSRST1
is only 30 ns. If GPIO3 is hi-Z, then minimum t
GSRST1
is
100 µs, to provide time for an on-chip 1 M pulldown device (active while RST is low) to discharge the pin.
