USB designs are complex. Despite USB’s benefits as a robust, compact and easy to use communication interface, its initial development requires significant time, design effort and cost. USB expertise is required to overcome implementation issues that can vary from compatibility to poor performance. USB firmware is a time consuming task which may impact time to market and requires complex USB debug tools and techniques. Some competitors require complex implementations of external crystals and discrete components, further increasing the cost and design effort. Additionally, to further complicate the design, new versions of operating systems can create compatibility issues which can require a product update. Testing and maintaining drivers for various operating systems and versions of each operating system is extremely difficult and requires a great amount of resources. Silicon Labs provides driver updates for new operating systems as needed. Silicon Labs’ USB bridge solutions are aimed at making USB easy by enabling developers to drop in a bridge device and begin communications. This approach reduces development time, eliminates firmware complexity and maintenance, and reduces time to market.
