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.
Here are a few examples, which quotes fit for which ICs. More information is available with the link to the manufacturer page.
