Maxim Integrated DS8005

The DS8005 dual smart card interface is a low-cost, dual analog front-end for an IC card reader interface that needs to communicate with two smart cards in a mutually exclusive fashion. The analog interface is designed for use in ISO 7816, EMV®, and B-CAS applications. The device is functionally similar to two DS8024s with external multiplexing to select the active interface, but also includes low power and 1.8V card support.

GENERAL DESCRIPTION

Additionally, the device is designed for applications where the C4/C8 (AUX1/AUX2) contacts are not required on either card interface. The device is provided in a 28-pin SO package. The pinout is backwards compatible with the DS8313, allowing applications to use the same footprint and PCB for applications that communicate with either one or two smart cards. The device is designed to be used with microcontrollers that contain an ISO 7816 UART, or have the bandwidth to run this protocol in software by bit-banging IO ports. If the microcontroller does not have the capability of running the ISO 7816 UART, the DS8007 is the more appropriate product selection.
