對於物聯網（IoT）應用，需要兼顧高速和低速時鐘下運行的MCU。諸如被藍牙智慧，藍牙低功耗（BLE），WiFi，ZigBee和sub-GHz RF的無線通訊廣泛使用的16.0 / 24.0 / 32.0 / 40.0MHz和32.768KHz的典型頻率。HKC提供針對物聯網應用適配的全系列可靠頻率產品。
對於可穿戴設備，低功耗是一個主要要求。配備低ESR晶振的振盪電路是首選，HKC為可穿戴應用提供了一個選擇低ESR晶振的可能。
HKC的IoT晶振可用於不同的工作溫度範圍，從-20至+ 70°C（對於消費產品），-40至+ 85°C（工業應用）和-40至+ 125°C（嚴苛環境）。
外形小也並不總是趨勢！有許多物聯網產品，其中小外形不是一個問題，但成本是最關鍵的。 HKC仍然生產傳統的封裝尺寸，用於成本敏感的IoT應用。
