Which crystals did the Silicon Labs MCU boss choose when doing the original design?

MCU (MicrocontrollerUnit), also known as microcontroller or microcontroller, appropriately reduces the frequency and specifications of the CPU, and integrates peripherals such as memory (Memory), counter (Timer), USB, A/D conversion, UART, PLC, DMA, etc. The interface and even the LCD driver circuit are integrated on a single chip to form a chip-scale computer. Thereby realizing the function of terminal control, it has the advantages of high performance, low power consumption, programmability, and high flexibility.

EPSON Epson RTC + Panasonic battery combination

IoT (Internet of things), the Internet of Things has opened up a large number of new applications and created more desires for monitoring or control functions, but power consumption also increases with the increase in functions. If a device is always working and requires ultra-low power consumption. You can consider using RTC, because the RTC real-time clock is always working.
