Smart Card Interface  
DS805  
General Description  
Features  
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  
♦ Analog Interface and Level Shifting for IC Card  
Communication  
♦ ±±8k ꢀminꢁ ꢂSꢃ ꢀ(HBꢁ ꢄrotection on Card Interfaceꢅ  
®
designed for use in ISO 7816, EMV , and B-CAS appli-  
♦ Ultra-Low Stop-Bode Current, Leꢅꢅ than 10nA  
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.  
Typical  
♦ Internal IC Card Supply-koltage Generation  
5.0k ±5ꢆ, ±0mA ꢀmaꢇꢁ  
3.0k ±±ꢆ, ꢈ5mA ꢀmaꢇꢁ  
1.±k ±10ꢆ, 30mA ꢀmaꢇꢁ  
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.  
♦ Automatic Card Activation and ꢃeactivation  
Controlled by ꢃedicated Internal Sequencer  
♦ I/O Lineꢅ from (oꢅt ꢃirectly Level Shifted for  
Smart Card Communication  
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.  
♦ Fleꢇible Card Cloc8 Generation, Supporting  
ꢂꢇternal Cryꢅtal Frequency ꢃivided by 1, 2, 4, or ±  
♦ (igh-Current, Short-Circuit and (igh-Temperature
