DESCRIPTION

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.
