Description

The AT83C24 is a smart card reader interface IC for smart card reader/writer applica-

tions such as EFT/POS terminals and set top boxes. It enables the management of

any type of smart card from any kind of host. Up to 8 AT83C24 can be connected in

parallel using the programmable TWI address.

Its high efficiency DC/DC converter, low quiescent current in standby mode makes it

particularly suited to low power and portable applications. The reduced bill of material

allows reducing significantly the system cost. A sophisticated protection system guar-

antees timely and controlled shutdown upon error conditions.

The AT83C24NDS is a dedicated version approved by NDS for use with NDS Video-

Guard conditional access software in set-top boxes. All AT83C24 datasheet is

app licab le to AT83 C24N DS. The main difference s b etween AT83C2 4 and

AT83C24NDS are listed below:

1/ CLASS A card supplied with CVCC = 4.75 to 5.25V for AT83C24NDS,

CLASS A card supplied with CVCC = 4.6 to 5.25V for AT83C24

2/ 18MHz minimum on input clock for AT83C24NDS

3/ Up to 10µF for capacitor connected on CVCC pin for AT83C24,

3.3µF mandatory for AT83C24NDS
