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.
