Traditional serial communications ports remain the primary means of interconnectivity for a host of different computer and peripheral equipment, from ATMs to industrial control and building automation. While there are standards, all serial ports / UARTs are not created equal. Oxford's serial connectivity solutions are standards compliant, tested, high-performance solutions with certified device drivers for a wide range of operating systems that eliminate design risk and speed time-to-market.

Every device has flexible customization and advanced performance feature capabilities. And, save on BOM costs with exactly the right peripherals and general purpose I/Os for the required task, all without a lot of external components.

Oxford's design tool, called Oxide, enables engineers to customize serial connectivity devices in minutes. No more complex, time consuming, error prone manual editing of programming files and driver source code. Everything needed to help accelerate new product introductions.
