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
applicable to AT83C24NDS. The main differences between AT83C24 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
