Description :<\/span><\/span><\/strong><\/p>\n

SD6830 est un \u00e9metteur de t\u00e9l\u00e9commande, compos\u00e9 d’un processeur 4 bits optimis\u00e9 avec ROM et
\nRAM. Il contient une r\u00e9initialisation \u00e0 la mise sous tension, une minuterie de surveillance et un g\u00e9n\u00e9rateur de fr\u00e9quence porteuse. Le
\nLe SD6830 fournit diverses fr\u00e9quences porteuses pour coder la sortie de la matrice cl\u00e9 et poss\u00e8de
\ntransistor int\u00e9gr\u00e9 pour piloter la LED infrarouge. Le SD6830 est pris en charge avec un logiciel
\noutil de d\u00e9veloppement, qui permet le d\u00e9veloppement de code dans un environnement PC. Il permet \u00e0 l’utilisateur
\npour simuler le SD6830 au niveau instruction.<\/p>\n
