4.6. (U)SIM Interface
(U)SIM interface of UG96/UG95 and M95 R2.0 supports 1.8V or 3.0V USIM/SIM cards by default. The pin
assignment of UG96/
UG95’s (U)SIM interface is compatible with that of the M95 R2.0’s (U)SIM1 interface,
except
that UG96/UG95’s pin SIM1_PRESENCE is not compatible with M95 R2.0’s USIM_PRESENCE.
A reference design of 6-pin (U)SIM interface is shown in the figure below:
