SIM interface

The SIM interface is programmed to support 3V and 1.8V SIMs. SIM supply voltage is selected by with register

in the UEMCLite. It is only allowed to change the SIM supply voltage when the SIM IF is powered down. The SIM

power up/down sequence is generated in the UEMCLite.

The SIM interface is powered up when the SIMCardDet signal indicates ”card in”. This signal is derived from the

BSI signal.

SIM interface is implemented in two ASICs, UPP and UEMCLite. The SIM interface is the electrical interface between

the Subscriber Identity Module Card (SIM Card) and mobile phone (via UEMCLite device).
