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.
MicroSD card interface
Figure 71 MicroSD card interface
The MicroSD card is connected to the engine by an external level shifter with an ESD protection filter. Supplied
voltages:
•
VSD: 2.85 V (from level shifter)
•
VIO: 1.8 V (from VIO SMPS)
Hot swap is supported, which means that the card may be plugged in/out at any time, without removing the
battery.
