Abstract

Le microprocesseur 1 est alimenté entre la masse 9 et la borne 7 par une tension régulée provenant de l'extérieur. La mémoire morte programmable électriquement 2 type PR diamétre M est alimentée entre la masse 9 et la borne 8. La borne 5 permet de synchroniser les différentes actions internes du dispositif vis-à-vis de l'extérieur. La borne 6 constitue le seul accès au dispositif pour les informations entrantes et sortantes. Application : cartes de crédit.
