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 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 direct access to the multiplexed bus of an 80C51-compatible microcontroller through MOVX memory addressing.
