恩智浦具(jù)有(yǒu)广泛的小(xiǎo)型全功能(néng)实时时钟产(chǎn)品组合，為(wèi)各种终端应用(yòng)实现更高的精(jīng)度和更低的功耗。恩智浦的RTC為(wèi)您的系统提供了广泛的功能(néng)，从電(diàn)池管理(lǐ)和报警到时间戳和篡改检测功能(néng)。也提供了符合汽車(chē)AEC-Q100的器件。
高精(jīng)度RTC
NXP RTCs可(kě)以将精(jīng)度做到 +/- 3ppm 以内，且具(jù)有(yǒu)实时日历时钟；集成RAM；温度补偿；集成晶體(tǐ)振荡器；電(diàn)源管理(lǐ)等特色功能(néng)。
低功耗RTC
具(jù)有(yǒu)低功耗，可(kě)在提供实时时钟功能(néng)的同时实现较長(cháng)電(diàn)池寿命。提供高能(néng)效设备的同时也提供I2C或SPI总線(xiàn)接口。工(gōng)业级的NXP RTCs可(kě)以将功耗做到 100nA（PCF2123）以内。
汽車(chē)级RTC
设计用(yòng)于最高可(kě)靠性和最低功耗的设备，并与I2C或SPI总線(xiàn)接口一起提供。其工(gōng)作(zuò)温度范围扩展至125ºC，同时符合AEC-Q100汽車(chē)规范。
