The DS8007 is a multiprotocol, low-cost, dual, smart card interface that supports all ISO 7816, EMV™, and GSM11-11 requirements. This one mixed-signal peripheral manages all the details of the interface between a microcontroller and two, independent smart cards.

 
The DS8007 provides all electrical signals necessary to physically interface a microcontroller with two separate smart cards. The device contains a dedicated internal sequencer that controls automatic card activation and deactivation, and an ISO UART for data communication. Charge pumps and voltage regulators allow the device to operate from a 2.7V to 6.0V supply voltage, and to produce two independent smart card supply voltages, either of which can be 1.8V, 3.0V, or 5V. Communication with the microcontroller is provided by a standard, parallel 8-bit bus that carries either data in a non multiplexed configuration or data and address in multiplexed configuration.

An evaluation kit (DS8007-KIT) is available, this is a proven platform to conveniently evaluate the capabilities of the DS8007 smart card interface chip. It includes a DS5002FP secure microcontroller to control the smart card interface. Two card sockets are included (one full size, one SIM size) to communicate with any 1.8V, 3V, or 5V IC card. An LCD screen can provide detailed feedback on program operation and aids in debugging applications.
The DS8007 EV kit passed EMV™ 4.0 Level 1 Interface Module Certification by an EMV accredited certification laboratory for Type 1 approval testing. All Level 1 tests have passed using DS8007 EV kit platform.

Sample Kit (DS8007-SKT) including three DS8007-ENG Samples, documentation for DS8007 and Evaluation Kit, one ACOS3 Microprocessor Smart Card & resource software CD is also available.
