La famille LAN8670\/1\/2 de PHY Ethernet simplifie l\u2019architecture pour connecter des composants \u00e0 faible vitesse \u00e0 un r\u00e9seau Ethernet standard<\/span><\/h3>\n

Les constructeurs automobiles cherchent \u00e0 remplacer les sous-syst\u00e8mes de passerelle traditionnels par une technologie permettant de migrer les applications vers un r\u00e9seau Ethernet et ainsi acc\u00e9der facilement aux informations en p\u00e9riph\u00e9rie du Cloud. Afin d\u2019offrir aux \u00e9quipementiers automobiles des solutions Ethernet qualifi\u00e9es pour ce march\u00e9, Microchip Technology annonce le lancement de ses premiers PHY Ethernet qualifi\u00e9s pour l\u2019automobile. Cette famille de composants 10BASE-T1S, certifi\u00e9e AEC-Q100 de grade 1, comprend le LAN8670, le LAN8671 et le LAN8672<\/a>.<\/p>\n

Des circuits pr\u00eats \u00e0 l\u2019emploi\u00a0<\/strong><\/p>\n

Les PHY Ethernet 10BASE-T1S LAN8670\/1\/2 sont pr\u00eats \u00e0 l\u2019emploi en mati\u00e8re de s\u00e9curit\u00e9 fonctionnelle et sont con\u00e7us pour \u00eatre utilis\u00e9s sur des applications ISO 26262. Gr\u00e2ce \u00e0 ces composants, il est d\u00e9sormais possible de connecter des p\u00e9riph\u00e9riques \u00e0 faible vitesse, qui jusque-l\u00e0 n\u00e9cessitaient leurs propres syst\u00e8mes de communication, \u00e0 un syst\u00e8me Ethernet standard sur des applications automobiles.
\n\u00ab\u00a0Microchip continue de privil\u00e9gier les solutions de connectivit\u00e9 pour l\u2019industrie automobile en compl\u00e9tant sa ligne de produits 10BASE-T1S\u00a0\u00bb, souligne Matthias Kaestner, vice-pr\u00e9sident du d\u00e9partement des produits automobiles chez Microchip. \u00ab\u00a0Avec cette nouvelle technologie, les capteurs et actionneurs utilis\u00e9s dans le monde r\u00e9el seront connect\u00e9s sur tout le chemin menant au Cloud, permettant d\u2019utiliser une architecture Ethernet fluide d\u2019un bout \u00e0 l’autre du r\u00e9seau.\u00a0\u00bb
\nLa possibilit\u00e9 de connecter plusieurs PHY Ethernet \u00e0 une ligne de bus commune simplifie la mise en \u0153uvre des applications automobiles sur une architecture unique bien connue, et permet de r\u00e9aliser des \u00e9conomies sur les co\u00fbts de mise en \u0153uvre en r\u00e9duisant le c\u00e2blage et le nombre de ports de commutation. Les LAN8670\/1\/2 permettent aux p\u00e9riph\u00e9riques du r\u00e9seau d\u2019utiliser l\u2019Ethernet ainsi que le protocole Internet (IP) pour communiquer facilement avec le reste de l\u2019infrastructure du r\u00e9seau. Ces composants int\u00e8grent des fonctions de diagnostic PHY avanc\u00e9es pour offrir \u00e0 l\u2019utilisateur des capacit\u00e9s de r\u00e9solution des probl\u00e8mes. De plus, la fonctionnalit\u00e9 veille\/r\u00e9veil permet des modes faible consommation.<\/p>\n

Des performances EMC\/EMI am\u00e9lior\u00e9es<\/strong><\/p>\n

Les sp\u00e9cifications 10BASE-T1S incluent le d\u00e9bit 10\u00a0Mbit\/s, le mode half-duplex, une topologie flexible avec une architecture de bus Multi-Drop et point \u00e0 point, ainsi que l\u2019utilisation d\u2019une paire de conducteurs sym\u00e9triques. Ces composants int\u00e8grent \u00e9galement des performances EMC\/EMI am\u00e9lior\u00e9es (respectivement de compatibilit\u00e9 \u00e9lectromagn\u00e9tique et de protection contre les interf\u00e9rences). Gr\u00e2ce \u00e0 la compatibilit\u00e9 TSN avec les r\u00e9seaux sensibles au temps (Time-Sensitive Networking), on obtient une meilleure synchronisation temporelle sur les r\u00e9seaux Ethernet tr\u00e8s \u00e9tendus. La synchronisation temporelle est critique pour de nombreuses applications au sein des architectures zonales automobiles.
\nMicrochip a \u00e9t\u00e9 un contributeur essentiel du d\u00e9veloppement de ces normes en collaboration avec le groupe IEEE pour la technologie 10BASE-T1S qualifi\u00e9e pour l\u2019automobile. Cette technologie simplifie la conception de syst\u00e8mes en \u00e9tendant la port\u00e9e de l’Ethernet aux p\u00e9riph\u00e9riques qui se trouvent habituellement en p\u00e9riph\u00e9rie du r\u00e9seau.<\/p>\n
