Most USB microcontrollers on the market have limited or no high precision analog capabilities; this forces customers to add external components, thereby increasing BOM cost and design complexity. A typical application also requires more than just USB connectivity. For example, a data logging system may require reading an external sensor and computing some data to provide some results that can be sent to a computer via USB. In this case, if the microcontroller provides limited CPU performance, the system will experience performance bottlenecks which compromises the application. Silicon Labs’ USB solutions are fully integrated mixed-signal MCUs that provide full system-on-a-chip integration. They eliminate unnecessary cost and complexity associated with adding external components, yet still provide high computing power capabilities.
