实时时钟(RTC) IC在电子电路中用于记录时间。多数应用对于维持高精度计时有很高要求,特别是在特殊时期或设备主电源关断时。在此期间,RTC IC利用辅助电池或超级电容供电,必须保持可靠的性能。正如预期的那样,除了精度、耐用性和小封装尺寸之外,功耗也是大多数实时时钟设计的关键因素。大多数现代RTC通过支持串口来减少引脚数量。Maxim提供各种高精度、低功耗、小型封装和基于MEMS(微机电系统)的实时时钟,以满足用户的应用需求。

  • 使用包含自动增益控制(AGC)电路的IC可降低功耗。
  • 基于MEM的RTC可提高冲击和振动容限。
  • 专有的SYNC功能支持RTC与外部时钟同步。
  • 集成晶振或MEMS振荡器的RTC提供多种途径减小电路板空间。
