DS8007A 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 GSM1111 requirements. Through its 8-bit parallel bus and dedicated address selects (AD3 AD0), the DS8007A can easily and directly connect to the nonmultiplexed bytewide bus of a Maxim secure microcontroller. Optionally, the parallel bus can be multiplexed to allow...
