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. T he m ain difference s b etween AT 83C2 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 Smart Card Reader Interface with Power Management AT83C24 AT83C24NDS |
