(Note 3)
Note 3:
The write cycle time (t
WR
) is the time from a valid stop condition of a write sequence to the end of the internal erase/program cycle. During the write cycle, the
NM24C04U/05U bus interface circuits are disabled, SDA is allowed to remain high per the bus-level pull-up resistor, and the device does not respond to its slave address.
语音作为自然的人机接口，可以使车载导航系统实现更安全、更人性化的操作。通过国内外车载导航系统的功能对比可知，支持语音交互是车载导航系统的一个发展趋势。另外，市场信息服务公司J.D Power and Associates的调研数据也表明，56％的消费者更倾向于选择声控的导航系统。因此，开发车载语音导航系统是很有意义的。目前，国内已经具备开发车载语音导航系统的技术基础，特别是文语转换TTS技术...[详细]
