　　賽普拉斯F-RAM的車載信息娛樂

　　對新功能的需求正在推動快速汽車信息娛樂增長。九百萬汽車信息娛樂系統(tǒng)在201生產(chǎn)，預(yù)計年產(chǎn)量將迅速增長到6000萬由2019。汽車信息娛樂系統(tǒng)（如圖1所示）提供了新的功能，如實時本地交通和零售信息，基于雷達的泊車輔助和安全系統(tǒng)，獨立的后方乘客音頻/視頻，無線互聯(lián)網(wǎng)和自適應(yīng)語音控制。這些新功能需要額外的高性能，高可靠性的非易失性存儲器。EEPROM不能滿足這些要求而不增加設(shè)計成本。汽車信息娛樂系統(tǒng)需要高性能、高可靠性、低成本的非易失性存儲器。

　　Common design problems engineers face include：

　　Automotive infotainment systems must store settings， status， and navigation data on power loss.

　　The Soak Time for EEPROMs requires 5 ms of active power per Page Write.

　　The Soak Time requires additional capacitors or batteries to perform a Page Write on power loss， increasing system cost.

　　Automotive infotainment systems exceed the 1-million-cycle Write Endurance limitation of EEPROMs.

　　Wear leveling is required to improve EEPROM Write Endurance to support a 20-year automotive lifetime requirement.

　　Wear leveling requires up to 8x the memory capacity and additional software， thus， increasing system cost.

　　Automotive manufacturers require AEC-Q100-qualified non-volatile memories.

　　Cypress‘s F-RAM solves these problems. F-RAM requires no Soak Time， eliminating the need for additional capacitors or batteries to complete a Page Write on power loss. It also provides 100 trillion write cycles， eliminating the need for Wear Leveling. Cypress now offers AEC-Q100-qualified memories in volume. Therefore， Cypress F-RAM is a high-performance， high-reliability， low-cost replacement for EEPROMs in a fast-growing market.
