Les microcontrôleurs PIC16F145X à 14 et 20 broches constituent à ce jour les microcontrôleurs USB de Microchip les plus économiques et les plus petits. Disponibles en boîtiers miniatures de 4 x 4 mm et dotés d’un vaste éventail de périphériques intégrés, ces circuits sont parfaits pour des applications embarquées requérant la connectivité USB en plus du tactile capacitif, tel que les oxymètres de pouls, les accessoires pour PC et les clés électroniques de protection.
\nLes PIC18F2X\/4XK50, disponibles en boîtiers à 28 et 40\/44 broches, constituent une solution de migration rentable compatible en termes de brochage, pour les clients utilisant des microcontrôleurs USB PIC18 plus anciens. Les trois membres de cette famille possèdent une tension de fonctionnement comprise entre 1,8 V et 5 V et intègrent une unité périphérique CTMU de mesure de temps de charge (Charge Time Measurement Unit) pour des claviers capacitifs  et des fonctions de mesure plus performantes dans des applications telles que les stations audio et enregistreurs de données.     
\nLa famille des PIC18F97J94 est la première de Microchip à intégrer sur un seul microcontrôleur PIC 8 bits le contrôleur d’écrans LCD, un module horloge temps-réel calendrier doté d’une broche Vbat et la connectivité USB. Disponible en boîtiers de 64, 80 et 100 broches, cette famille de 9 membres est dotée d’un contrôleur d’écrans LCD 60 x 8, pour un total de 480 segments, ce qui permet de se passer d’un contrôleur externe pour les applications à grand afficheur à segments. La famille intègre également une horloge\/calendrier temps réel (RTCC) dotée d’une batterie de secours idéale pour les applications du type domotique ou panneaux de sécurité, scanners portatifs et compteurs d’énergie monophasés.
\nAfin de réduire les phases de développement, la pile de protocole USB, téléchargeable depuis la bibliothèque d’applications gratuite de Microchip (MLA), inclut des drivers de classe pour de nombreuses classes USB courantes , y compris HID, CDC, stockage de masse, Win-USB et Audio-MIDI. Ces drivers sont compatibles avec les 15 nouveaux microcontrôleurs PIC de Microchip.<\/p>\n
