Figure 24 SIM interface
The EM ASIC AVILMA 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 interface.
The SIM 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 AVILMA)
The card removal is detected by a push detect switch.
