TOKYO, December 12, 2011 /PRNewswire/ --

- Se consigue el primer rendimiento industrial con 300.000 escrituras de datos de la industria y una retención de datos de 50 años a 125 grados C -

Seiko Instruments (SII) ha anunciado la disponibilidad el 12 de diciembre de la serie S-25AxxxB de EEPROM SPI, diseñada específicamente para su uso en el extremadamente exigente mercado del automóvil. Las revolucionarias memorias EEPROM S-25AxxxB establecen un record de rendimiento industrial de 300.000 escrituras de datos a 125 grados C, además de una retención de datos de 50 años. La capacidad de la memoria es de 8 k a 256 k bits.

Los diseños actuales de los automóviles precisan memorias EEPROM cada vez más avanzadas para los sistemas de a bordo para controlar el funcionamiento del coche, consumo de combustible, y asegurar el confort y la seguridad de los pasajeros. Además de requerir memorias EEPROM de más capacidad, las aplicaciones de automoción también precisan una seguridad y fiabilidad extremas. La gama SII S-25AxxxB se ha desarrollado para responder específicamente a las necesidades del mercado del automóvil.

A pesar de que el rendimiento de los ciclos de borrado y escritura de una EEPROM convencional suele descender a elevadas temperaturas, la serie S-25AxxxB asegura un rendimiento de hasta 300.000 escrituras a 125 grados C, además de la retención de los datos en la EEPROM durante un periodo de hasta 50 años.

Gracias al saber hacer propio de SII, las nuevas EEPROM van protegidas para eliminar la pérdida electrónica de bits; consiguiendo un tiempo de escritura de 8 k a 256 k bits, y la utilización de circuitos especiales de detección de baja potencia y fluctuación de tensión para la prevención de errores causados por los ruidos eléctricos o variaciones de corriente. La gama S-25AxxxB está disponible en los paquetes SOP-8, TSSOP-8 y TMSOP-8.

Las aplicaciones de automoción típicas incluyen motor, transmisión y sistemas de control EPS; ABS, ESC (Electronic Stability Control), y airbags; entrada sin llave, aire acondicionado, pantallas de tablero, y BCM (Body Control Module). SII prevé unas ventas de 5 millones de piezas anualmente.
