Le MLX81113 int\u00e8gre un micro-contr\u00f4leur int\u00e9gr\u00e9 RISC 16 bits MLX16 FX dot\u00e9 de 2 ko de RAM et 32 ko de m\u00e9moire Flash utilisable pour les applications, ainsi que d\u2019une m\u00e9moire ROM pour des performances d\u2019application accrues. L’EEPROM embarqu\u00e9e est port\u00e9e \u00e0 576 octets pour stocker des donn\u00e9es utilisateur, comme les coefficients d’\u00e9talonnage des LED, afin d\u2019assurer une luminosit\u00e9 et une couleur uniforme, point crucial pour les applications automobiles.
\nLes quatre sorties de courant sont programmables par logiciel et fournissent jusqu’\u00e0 60 mA, ce qui permet d\u2019utiliser une large gamme de LED RGB provenant de diff\u00e9rents fournisseurs. Une commande PWM (Pulse Width Modulation, ou modulation de largeur d’impulsion) ind\u00e9pendante, configurable jusqu’\u00e0 16 bits de r\u00e9solution, permet d’obtenir n’importe quelle nuance de couleur et d\u2019ajuster le niveau de luminosit\u00e9 de la LED RGB connect\u00e9e. La surveillance de temp\u00e9rature int\u00e9gr\u00e9e assure une stabilit\u00e9 de couleur sur toute la plage de temp\u00e9rature, de -40\u00b0C \u00e0 +125\u00b0C, et permet de compenser les variations de temp\u00e9rature sur tous les canaux. Toute d\u00e9rive de temp\u00e9rature de la couleur rouge, verte ou bleue peut \u00eatre int\u00e9gralement compens\u00e9e. Pour un d\u00e9veloppement d’application rapide, une suite d’outils compl\u00e8te est disponible, comprenant un circuit imprim\u00e9 d’\u00e9valuation, ainsi qu’un \u00e9mulateur in-situ et un compilateur C. Pour faciliter le d\u00e9veloppement de logiciel par les utilisateurs, tous les composants logiciels essentiels tels que le driver LIN, le mixage de couleurs et la biblioth\u00e8que math\u00e9matique, ainsi que les routines d’initialisation du CI, sont \u00e9galement fournies.
\n\u00ab A l\u2019avenir, l’\u00e9clairage sera l’une des caract\u00e9ristiques cl\u00e9s de la personnalisation et de la diff\u00e9renciation des habitacles automobiles. Avec ce nouveau produit, nous \u00e9largissons encore notre gamme de produits d’\u00e9clairage pour soutenir cette tendance, \u00bb d\u00e9clare Michael Bender, Responsable de la ligne de produits LIN chez Melexis. \u00ab Nos drivers de LED RGB(W) compatibles LIN permettent d\u2019obtenir un \u00e9clairage d’ambiance sophistiqu\u00e9 et \u00e9conomique, pour les v\u00e9hicules d’entr\u00e9e et de milieu de gamme, comme pour les v\u00e9hicules de luxe. Le MLX81113 rel\u00e8ve le niveau des performances et r\u00e9duit le nombre de composants externes, gr\u00e2ce \u00e0 sa tr\u00e8s grande robustesse CEM issue de la technologie SOI (Silicon On Insulator, ou silicium sur isolant). En outre, il est con\u00e7u selon la norme ISO 26262 pour faciliter la certification de s\u00e9curit\u00e9 fonctionnelle du syst\u00e8me. \u00bb<\/p>\n
