DS8007 Description
The DS8007 multiprotocol dual smart card interface is a low-cost, dual smart card reader interface supporting all ISO 7816, EMV, and GSM11-11 requirements. Through its 8-bit parallel bus and dedicated address selects (AD3 AD0), the DS8007 can easily and directly connect to the nonmultiplexed byte-wide bus of a Maxim/Dallas secure microcontroller. Optionally, the parallel bus can be multiplexed to allow direct access...
