A small, low power member has been added to Silicon Labs’ family of USBXpress bridge devices. It is said to provide a simpler, faster way to add USB connectivity to new and legacy embedded designs.

According to Silicon Labs, the CP2102N USB controller eliminates complex, time consuming firmware development and provides advanced functionality in QFN packages as small as 3 x 3 mm. The CP2102N simplifies USB-to-UART connectivity and speeds time to market for a range of portable, power sensitive and space constrained applications such as USB dongles, point-of-sale terminals, data loggers, gaming controllers and personal medical devices.

The device can add USB functionality to new designs and update existing RS232 designs to USB using minimal components and PCB space.

With a USB 2.0 Full Speed controller and UART interface, the CP2102N has an operating current of less than 10mA and extends battery life for power sensitive applications. Integrated features, such as a remote wake-up capability and USB battery charger detection, allow the device to wake-up a suspended host and to detect the type of charger connected to the system, reducing cost.

The device is pin and software compatible with Silicon Labs’ existing CP210x USB devices.
