ST8004 Smartcard Interface for Class A-B Cards; NDS Compliance
The ST8004 is a complete low cost analog interface for asynchronous 3V and 5V smart cards. It can be placed between the card and the microcontroller with few external components to perform all supply protection and control functions. Main applications are: smartcard readers for Set Top Box, IC card readers for banking, identification.
