General Description
The DS8007A multiprotocol dual smart card interface is
an automotive grade, low-cost, dual smart card reader
interface supporting all ISO 7816, EMV, and GSM11-
11 requirements. Through its 8-bit parallel bus and dedi-
cated address selects (AD3–AD0), the DS8007A can
easily and directly connect to the nonmultiplexed byte-
wide bus of a Maxim secure microcontroller. Optionally,
the parallel bus can be multiplexed to allow direct
access to the multiplexed bus of an 80C51-compatible
microcontroller through MOVX memory addressing.
One integrated UART is multiplexed among the inter-
faces to allow high-speed automatic smart card pro-
cessing with each card-possessing, independent,
variable, baud-rate capability. The card interface is con-
trolled by internal sequencers that support automatic
activation and deactivation sequencing, handling all
actions required for T = 0, T = 1, and synchronous pro-
tocols. Emergency deactivation is also supported in
case of supply dropout. A third card is supported
through the auxiliary I/O. The same set of I/O can option-
ally be used as additional serial interface for the UART.
The DS8007A provides all electrical signals necessary
to interface with two smart cards. The integrated volt-
age converter ensures full cross-compatibility between
1.8V/3V/5V cards and a 1.8V/3V/5V environment, and
allows operation within a 2.7V to 6V supply voltage
range. The standard DS8007 revision is available for
nonautomotive applications.
