Simply add USB to your design with bridge devices from Silicon Labs

Silicon Labs’ CP21xx USB bridge ICs eliminate software complexity and driver compatibility issues, providing a cost-effective, small-footprint turnkey solution for adding USB and human interface device (HID) - USB connectivity to applications such as personal medical devices, cellular and cordless phones, smart card and flash card readers, personal digital assistants, MP3 players, bar code readers, wireless modems and industrial control systems.

With the rapid proliferation of USB and HID-USB in the embedded world, developers are looking for painless, economical ways to embed USB connectivity in their designs. Silicon Labs developed the CP21xx bridge family so that designers can add USB to microcontroller-based applications without the cost and complexity of developing sophisticated USB software. The CP21xx ICs require no USB expertise to deploy, enabling developers to focus time and resources on end applications.
