对于物联网（IoT）应用，需要兼顾高速和低速时钟下运行的MCU。诸如被蓝牙智能，蓝牙低功耗（BLE），WiFi，ZigBee和sub-GHz RF的无线通信广泛使用的16.0 / 24.0 / 32.0 / 40.0MHz和32.768KHz的典型频率。HKC提供针对物联网应用适配的全系列可靠频率产品。
对于可穿戴设备，低功耗是一个主要要求。配备低ESR晶振的振荡电路是首选，HKC为可穿戴应用提供了一个选择低ESR晶振的可能。
HKC的IoT晶振可用于不同的工作温度范围，从-20至+ 70°C（对于消费产品），-40至+ 85°C（工业应用）和-40至+ 125°C（嚴苛环境）。
外形小也并不总是趋势！有许多物联网产品，其中小外形不是一个问题，但成本是最关键的。 HKC仍然生产传统的封装尺寸，用于成本敏感的IoT应用。
