The following figure illustrates a reference design of (U)SIM interface with an 8-pin (U)SIM card
connector.
Figure 16: Reference Circuit of (U)SIM Interface with an 8-Pin (U)SIM Card Connector
If (U)SIM card detection function is not needed, keep USIM_DET unconnected. A reference circuit for
(U)SIM interface with a 6-pin (U)SIM card connector is illustrated in the following figure.
