IC Card Interface ICs with Built-in DC / DC Converter

This interface is the optimum IC's to use for a TV set and a video recorder with CAS card 'B-CAS card etc.' and a Smart Card readers. And very helpful for a flexible set designs such as a two voltage source set of 3.3V / 5.0V supply, a one voltage source set of 3.3V only and so on, as power source range is wide 'Controller side supply : 2.7V to 5.5V, Card source side supply : 3.0V to 5.5V' and DC / DC converter built-in.
This IC operated at -40ºC is ideal for reader of B-CAS card for auto motive application or smart card.
