Figure 59 SIM interface
The EM ASIC handles the detection of the SIM card. The detection method is based in the BSI line. Because of
the location of the SIM card, removing the battery causes a quick power down of the SIM IF.
The EM ASIC SIM1 interface supports both 1.8 V and 3.0 V SIM cards. The SIM interface voltage is first 1.8 V
when the SIM card is inserted, and if the card does not response to the ATR a 3 V interface voltage is used.
µSD card interface
The µSD card is connected to the engine by an external level shifter and ESD protection filter. Supplied
voltages:
• VMMC: 2.85 V (from level shifter)
• VIO: 1.8 V (from Retu)
The card removal is detected by a push detect switch.
