3.5 UICC/SIM/USIM Interface
PLS8-X/PLS8-V has two UICC/SIM/USIM interfaces compatible with the 3GPP 31.102 and
ETSI 102 221. These are wired to the host interface in order to be connected to an external
SIM card holder. Five pads on the SMT application interface are reserved for each of the two
SIM interfaces.
The UICC/SIM/USIM interfaces support 3V and 1.8V SIM cards.
The CCINx signal serves to detect whether a tray (with SIM card) is present in the card holder.
Using the CCINx signal is mandatory for compliance with the GSM 11.11 recommendation if
the mechanical design of the host application allows the user to remove the SIM card during
operation. To take advantage of this feature, an appropriate SIM card detect switch is required
on the card holder. For example, this is true for the model supplied by Molex, which has been
tested to operate with PLS8-X/PLS8-V and is part of the Gemalto M2M reference equipment
submitted for type approval. See Chapter 9 for Molex ordering numbers.
Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered after
removing the SIM card during operation. Also, no guarantee can be given for properly initializ-
ing any SIM card that the user inserts after having removed the SIM card during operation. In
this case, the application must restart PLS8-X/PLS8-V.

GND Ground connection for SIM interfaces. Optionally a separate SIM ground line using e.g.,
pad N11 may be used to improve EMC.

CCIN1
CCIN2
Input on the baseband processor for detecting a SIM card tray in the holder. If the SIM is
removed during operation the SIM interface is shut down immediately to prevent destruc-
tion of the SIM. The CCINx signal is active low.
The CCINx signal is mandatory for applications that allow the user to remove the SIM card
during operation.
The CCINx signal is solely intended for use with a SIM card. It must not be used for any
other purposes. Failure to comply with this requirement may invalidate the type approval of
PLS8-X/PLS8-V.
