AT83C24NDS - Smart Card Reader Interface

Download the AT83C24NDS datasheet PDF. This datasheet also covers the AT83C24B variant, as both devices belong to the same smart card reader interface family and are provided as variant models within a single manufacturer datasheet.

General Description

The AT83C24 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.
