NET+40
Le NET+40 est un microprocesseur 32 bits hautes performances et haute intégration conçu pour une utilisation dans les périphériques intelligents en réseau et les équipements Internet. Il inclut un cœur ARM7TDMI, la technologie MAC 10/100BaseT Ethernet intégral avec interface MII, un contrôleur DMA 10 canaux breveté et un contrôleur de mémoire sophistiqué supportant tous les périphériques mémoire couramment utilisés aujourd'hui.
Le NET+40 fait partie de la famille NET+ARM de microprocesseurs réseau primés. Cette famille fournit l'évolutivité et la compatibilité broche pour broche dans une grande variété de performances. Les microprocesseurs NET+ARM constituent le cœur matériel de la plate-forme NET+Works® de solutions hautement intégrées et testées permettant l'ajout d'intelligence et de connectivité aux appareils électroniques.
