Add USB connectivity to apps with legacy serial connections

Posted: 14 Feb 2011     Print Version  Bookmark and Share

Keywords:Universal serial bus  RS-232  plug-and-play 

Universal serial bus (USB) has become an enormous success in industrial and commercial applications as it continues to replace many legacy serial connections (i.e. RS-232, 485). USB is becoming the interface of choice for enabling connectivity to new applications with its ease of use, plug-and-play functionality and increased robustness.

However, for embedded solution designers, a USB implementation requires expert knowledge of the USB protocol, exhaustive software development and significant design time. In addition, USB-based microcontrollers may not offer the right peripheral set required for an application, resulting in time-to-market delays, increased design complexity and added cost.
