La nouvelle solution de Renesas r\u00e9pond aux exigences \u00e9lev\u00e9es de l’industrie automobile en mati\u00e8re de hautes performances, de mise en r\u00e9seau \u00e0 grande vitesse, de haute s\u00e9curit\u00e9 et de niveaux de s\u00fbret\u00e9 fonctionnelle \u00e9lev\u00e9s qui sont requis \u00e0 mesure que les architectures E\/E \u00e9voluent vers des domaines et des zones. La solution am\u00e9liore \u00e9galement consid\u00e9rablement l’efficacit\u00e9 du d\u00e9veloppement en permettant la r\u00e9utilisation du logiciel et en incluant les nouveaux PMIC de pointe con\u00e7us pour fonctionner de mani\u00e8re transparente avec les R-Car S4. <\/p>\n

\u00ab \u00c0 mesure que les architectures des v\u00e9hicules \u00e9voluent, une connexion s\u00e9curis\u00e9e aux services cloud et une gestion s\u00e9curis\u00e9e avec des syst\u00e8mes de contr\u00f4le embarqu\u00e9s dans le v\u00e9hicule sont des d\u00e9fis majeurs \u00bb, a d\u00e9clar\u00e9 Takeshi Kataoka, vice-pr\u00e9sident principal et directeur g\u00e9n\u00e9ral de la division commerciale Automotive Solution chez Renesas. \u00ab En tant que leader du march\u00e9 automobile, nous avons relev\u00e9 ces d\u00e9fis avec notre nouvelle solution R-Car S4, et les \u00e9quipementiers mondiaux ont d\u00e9j\u00e0 commenc\u00e9 \u00e0 concevoir des syst\u00e8mes de nouvelle g\u00e9n\u00e9ration avec cette solution. \u00bb<\/p>\n

Le R-Car S4 comprend plusieurs Arm Cortex A55, Cortex R52 et est le premier \u00e0 impl\u00e9menter un MCU RH850 pour la gestion des domaines de contr\u00f4le. Les SoC R-Car S4 offrent un grand nombre d’interfaces automobiles telles que 16x CAN FD, 16x LIN, 8x SENT, 1x FlexRay, 4x PCIe V4.0 et \u00e9galement un commutateur Ethernet 3 x 2,5Gbit \u00e0 large bande passante pour permettre des options de communication et de connectivit\u00e9 riches \u00e0 l’int\u00e9rieur et \u00e0 l’ext\u00e9rieur du v\u00e9hicule.<\/p>\n

La solution R-Car S4 permet aux concepteurs de r\u00e9utiliser jusqu’\u00e0 88 % du code logiciel d\u00e9velopp\u00e9 pour les R-Car de 3e g\u00e9n\u00e9ration et pour les applications des MCU RH850. L\u2019ensemble logiciel supporte le d\u00e9veloppement d\u2019applications pour R-Car S4 y compris les c\u0153urs temps r\u00e9el avec divers pilotes et logiciels de base tels que Linux BSP et des hyperviseurs. En outre, une plate-forme virtuelle (VPF) est disponible aupr\u00e8s d’une entreprise partenaire, permettant un d\u00e9veloppement et une \u00e9valuation pr\u00e9coces du logiciel afin de r\u00e9duire le temps et les co\u00fbts de conception.<\/p>\n

Les nouveaux PMIC pour R-Car offrent des modes de puissance avanc\u00e9s qui prennent en charge un fonctionnement \u00e0 tr\u00e8s faible puissance. Le PMIC RAA271041 accepte l’alimentation 12V du v\u00e9hicule et prend en charge un fonctionnement \u00e9tendu pour le d\u00e9chargement de la charge et des impulsions de d\u00e9marrage \u00e0 froid tout en fournissant la r\u00e9gulation de premi\u00e8re \u00e9tape. Le RAA271005 est un PMIC s\u00e9curis\u00e9 \u00e0 11 canaux qui prend la sortie du RAA271041 et la r\u00e9duit davantage aux diff\u00e9rentes tensions d’alimentation n\u00e9cessaires au R-Car S4 et \u00e0 ses p\u00e9riph\u00e9riques tels que la m\u00e9moire LPDDR4x. Les PMIC RAA271041 et RAA271005 offrent une solution d’alimentation compl\u00e8te, de la batterie du v\u00e9hicule \u00e0 la tension du syst\u00e8me.<\/p>\n

Des \u00e9chantillons des SoC R-Car S4 et des cartes d’\u00e9valuation sont disponibles d\u00e8s maintenant. www.renesas.com\/products\/automotive-products\/automotive-system-chips-socs\/r-car-s4-automotive-system-chip-soc-car-servercommunication-gateway<\/a>.<\/p>\n
