TOKYO, December 12, 2011 /PRNewswire/ --

- La mémoire la plus performante de l'industrie avec 300 000 écritures de données et une conservation de celles-ci sur 50 ans à 125 C  -

Seiko Instruments (SII) a annoncé le 12 décembre la disponibilité des EEPROM série SPI de la gamme S-25AxxxB, conçues spécialement pour une utilisation dans le très exigeant marché automobile. L'EEPROM S-25AxxxB permet 300 000 écritures de données et une conservation de celles-ci sur 50 ans à 125 C. La capacité mémoire va de 8 à 256 kilobits.

Les architectures automobiles actuelles nécessitent des EEPROM à plus haute performance sur les systèmes embarqués qui contrôlent le fonctionnement des voitures et leur consommation de carburant, tout en garantissant le confort et la sécurité des passagers. En plus du besoin d'EEPROM avec des capacités de plus en plus importantes, les applications automobiles exigent également une très haute fiabilité et sécurité. La gamme SII S-25AxxxB a été développée pour répondre spécialement aux besoins exigeants du marché automobile.

Alors que les EEPROM traditionnelles connaissent généralement des performances en écriture dégradées à haute température, la gamme S-25AxxxB offre des performances de 300 000 écritures de données à  125 C ainsi qu'une conservation des données de l'EEPROM pouvant atteindre 50 ans.

Utilisant le savoir-faire propriétaire de SII, les nouvelles EEPROM sont triées afin d'éliminer les erreurs sur les bits dues à des fuites électroniques ; elles offrent en outre un large éventail de capacités mémoire allant de 8 à 256 kilobits et utilisent des circuits spéciaux de faible puissance et de détection des fluctuations de tension afin d'empêcher les erreurs causées par le bruit ou les variations électriques. La gamme S-25AxxxB est disponible sous forme d'offres SOP-8, TSSOP-8 et TMSOP-8.

Les applications automobiles typiques incluent la motorisation, la transmission et les systèmes de contrôle EPS ; le système de freins antiblocage (ABS), le contrôle de stabilité électronique (ESC) et les airbags ; le système d'ouverture sans clé, la climatisation, les affichages du tableau de bord et le module BCM (Body Control Module). SII prévoit de vendre 5 millions d'unités chaque année.
