General Description
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 appli-
cations. 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. Additionally, the device is designed for appli-
cations 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 microcon-
trollers that contain an ISO 7816 UART, or have the
bandwidth to run this protocol in software by bit-bang-
ing IO ports. If the microcontroller does not have the
capability of running the ISO 7816 UART, the DS8007 is
the more appropriate product selection.
