The DS8007-ENG+ is a multiprotocol dual smart card interface in 48 pin LQFP package. This low cost card reader interface supports all ISO 7816, EMV and GSM11-11 requirements. Through its 8bit parallel bus & dedicated address selects (AD3-AD0) the DS8007 can easily and directly connect to nonmultiplexed byte wide bus of a Maxim secure microcontroller. Optionally, parallel bus can be multiplexed to allow direct access to multiplexed bus of an 80C51-compatible microcontroller through MOVX memory addressing. One integrated ISO 7816 UART is multiplexed among 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.
Supply voltage range is 2.7V to 6V
Operating temperature range from -40°C to 85°C
Integrated ISO 7816 UART provides complete interface/control for two separate smart card devices
