Multiprotocol Dual Smart Card Interface
Reset Output. This active-high output is provided for resetting external devices. The RSTOUT pin is driven
high until the DELAY pin reaches V
so it can externally be pulled down. The SUPL bit is set for each RSTOUT pulse.
Auxiliary I/O. This I/O pin allows connection to an auxiliary smart card interface.
Smart Card A I/O Data Line. This is the I/O data line associated with smart card A. This is also referred to
as the ISO C7 contact.
Smart Card A Auxiliary I/O. This is an auxiliary I/O associated with smart card A. This is also referred to
as the ISO C8 contact. This can be associated with synchronous cards.
Smart Card A Presence Contact. This is the active-high presence contact associated with smart card A.
Smart Card A Auxiliary I/O. This is an auxiliary I/O associated with smart card A. This is also referred to
as the ISO C4 contact. This can be associated with synchronous cards.
Smart Card A Ground. This must be connected to GND.
Smart Card A Clock Output. This is the clock output associated with smart card A. This is also referred to
as the ISO C3 contact.
Smart Card A Supply Voltage. This is the supply voltage output associated with smart card A. This is also
referred to as the ISO C1 contact.
Smart Card A Reset. This is the reset output associated with smart card A. This is also referred to as the
ISO C2 contact.
Smart Card B I/O Data Line. This is the I/O data line associated with smart card B. This is also referred to
as the ISO C7 contact.
Smart Card B Auxiliary I/O. This is an auxiliary I/O associated with smart card B. This is also referred to
as the ISO C8 contact. This can be associated with synchronous cards.
Smart Card B Presence Contact. This is the active-high presence contact associated with smart card B.
Smart Card B Auxiliary I/O. This is an auxiliary I/O associated with smart card B. This is also referred to
as the ISO C4 contact. This can be associated with synchronous cards.
Smart Card B Ground. This must be connected to GND.
Smart Card B Clock Output. This is the clock output associated with smart card B. This is also referred to
as the ISO C3 contact.
Smart Card B Supply Voltage. This is the supply voltage output associated with smart card B. This is also
referred to as the ISO C1 contact.
Smart Card B Reset. This is the reset output associated with smart card B. This is also referred to as the
ISO C2 contact.
Ground
Step-Up Converter Connection. Connect a low-ESR capacitor of 220nF between this pin and ground.
