美芯DS8007智能卡接口评估方案

美芯(Maxim)公司的DS8007是低成本多协议双智能卡接口器件,支持所有的ISO 7816, EMV™和GSM11-11规范.广泛用在银行终端入POS,ATM,PIN卡,通信,付费电视和接入控制等.本文介绍了DS8007的主要特性,方框图,典型应用电路以及DS8007开发评估板的材料清单(BOM)和详细电路图.

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 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.
