Microchip Technology Périphériques indépendants du cœur Microchip Technology
Les microcontrôleurs PIC Microchip Technology dotés de périphériques indépendants du cœur permettent aux concepteurs d'atteindre un nouveau niveau de performance pour les MCU 8 bits. Les produits offerts comprennent plusieurs modules sur carte conçus pour augmenter les capacités de tout système de commande et fournir aux conceptions intégrées un rendement exceptionnel. Les périphériques indépendants du cœur gèrent leurs tâches sans avoir besoin de code ni de supervision de la part du CPU pour assurer leur fonctionnement. En conséquence, ils simplifient la mise en place des systèmes de commande complexes et donnent aux concepteurs une souplesse leur permettant d'innover.
