\u00ab Le composant SuperFlash SST38LF6401RT renforce notre approche \u00e9volutive visant \u00e0 d\u00e9velopper des solutions int\u00e9grales de syst\u00e8mes spatiaux en utilisant nos microprocesseurs et FPGA tol\u00e9rants aux radiations ou durcis aux radiations \u00bb, explique Bob Vampola, vice-pr\u00e9sident du d\u00e9partement A\u00e9rospatiale et D\u00e9fense de Microchip. \u00ab Il offre la protection vitale dont ont besoin ces syst\u00e8mes spatiaux pour un traitement num\u00e9rique ultra fiable, qui n\u00e9cessitent une m\u00e9moire Flash d\u00e9di\u00e9e pour y stocker le code logiciel critique ou le flux binaire qui pilotent le syst\u00e8me complet \u00bb.<\/p>\n

Supportant une dose absorb\u00e9e totale accumul\u00e9e (TID, Total Ionizing Dose) allant jusqu\u2019\u00e0 50 krad, y compris lorsque la m\u00e9moire Flash est toujours polaris\u00e9e et en fonctionnement, le composant SST38LF6401RT <\/a>permet aux syst\u00e8mes de fonctionner sur un large \u00e9ventail d\u2019applications qui ne peuvent tol\u00e9rer une perte d’ex\u00e9cution du code, qui pourrait entra\u00eener de graves d\u00e9fauts et des pertes syst\u00e8me. C\u2019est le compl\u00e9ment id\u00e9al pour le processeur SoC durci aux radiations SAMRH71<\/a> bas\u00e9 sur un noyau Arm Cortex-M7 de Microchip. Il peut \u00e9galement \u00eatre utilis\u00e9 avec les FPGA RT PolarFire <\/a>de la soci\u00e9t\u00e9 pour permettre la reconfiguration des syst\u00e8mes en vol. Le composant est dot\u00e9 d\u2019une distribution de broches compatible avec la version industrielle \u00e9quivalente pour une transition ais\u00e9e vers les versions en plastique ou en c\u00e9ramique \u00e0 usage spatial au niveau de la carte \u00e9lectronique. La tension de fonctionnement du SST38LF6401RT varie de 3,0 \u00e0 3,6 V.<\/p>\n

Outils de d\u00e9veloppement et disponibilit\u00e9<\/u><\/strong><\/p>\n

Les \u00e9chantillons du composant SuperFlash SST38LF6401RT sont disponibles d\u00e8s \u00e0 pr\u00e9sent en version c\u00e9ramique et sont compatibles avec une carte d’\u00e9valuation et un logiciel de d\u00e9monstration disponibles sur simple demande. Un syst\u00e8me de r\u00e9f\u00e9rence de FPGA programmable en vol est \u00e9galement disponible sur demande, afin d\u2019associer le composant SuperFlash, un FPGA et un processeur SAMRH71 \u00e9quip\u00e9 d\u2019un logiciel compatible.<\/p>\n
