Internet of Things (IoT)

Internet of Things (IoT)

For Internet of Things (IoT) applications there are needs of running the MCU at both high speed and low speed clocks. Typical frequencies like 16.0 / 24.0 / 32.0 / 40.0 MHz and 32.768 KHz are widely used by wireless communications such as Bluetooth Smart, Bluetooth Low Energy (BLE), WiFi, ZigBee and sub-GHz RF. HKC offers a full series of reliable frequency products that are optimized for IoT applications.

For wearable devices, low power consumption is a major requirement. Oscillation circuit with low ESR crystal is preferred and hence HKC offers a low ESR option for wearable applications.

HKC’s IoT crystals are available in different operating temperature ranges, from -20 to +70°C for consumer products, -40 to +85°C for industrial applications, and -40 to +125°C for harsh environments.

Small is not always the trend! There are many IoT products where small form factor is not a concern but cost is most critical. HKC is still producing traditional package size for cost sensitive IoT applications.
