Multiprotocol Dual Smart Card Interface DS8007 The DS8007 multiprotocol dual smart card interface is a low-cost, dual smart card reader interface supporting all ISO 7816, and GSM11-11 requirements. Through its 8-bit parallel bus and dedicated address selects the DS8007 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 ISO 7816 UART is multiplexed among the interfaces to allow high-speed automatic smart card processing with each card-possessing, independent, variable, baud-rate capability. The card interface is controlled by internal sequencers that support automatic activation and deactivation sequencing, handling all actions required for T = 0, T = 1, and synchronous protocols. 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 optionally be used as additional serial interface for the UART. The DS8007 provides all electrical signals necessary to interface with two smart cards. The integrated voltage 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.
