Silicon labs controller solutions fall into two main classes: fixed function and fully-
programmable mixed-signal MCUs with integrated USB controller.
Fixed function CP210x USB to UART bridge devices with royalty-free VCP drivers
are the easiest and fastest way to add USB communication to your design – with no
changes to the controller firmware or PC application.
Mixed-signal MCUs are fully-programmable, featuring ISP FLASH (great for USB
bootloaders), a wide array of memory sizes, port I/O, and analog data converters.
All of these feature a calibrated oscillator, and so do not require an external crystal!
