Figure 1-3 Mini PCI Express identification
− USIM interface: The USIM interface provides the interface for a USIM card.
The USIM card can be inserted into the PC.
− USB interface: The USB interface supports three modes of USB 2.0 (low
speed, full speed, and high speed). Because there is not a separate USB-
controlled voltage bus, USB functions implemented on EM770 which are
expected to report as self-powered devices.
− Auxiliary signals: The auxiliary signals provide some other functions.
− Power sources and grounds: The PCI Express Mini Card provides two power
sources, including the one at 3.3 Vaux (3.3Vaux) and the one at 1.5 V(+1.5 V).
The EM770 uses the 3.3 voltage as the power supply.
