The AT83C24B is a smart card reader interface IC for smart card reader/writer applications 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 guarantees timely and controlled shutdown upon error conditions.

The AT83C24NDS is a dedicated version approved by NDS for use with NDS VideoGuard conditional access software in set-top boxes. All AT83C24B datasheet is applicable to AT83C24BNDS. The main differences between AT83C24B and AT83C24NDS are listed below:
1/ CLASS A card supplied with CVCC = to 5.25V for AT83C24NDS,

CLASS A card supplied with CVCC = to 5.25V for AT83C24B
2/ 18MHz minimum on input clock for AT83C24NDS
3/ Up to 10µF for capacitor connected on CVCC pin for AT83C24B,
3.3µF mandatory for AT83C24NDS
