USB to serial bridges
8 October 2014, Telecoms, Datacoms, Wireless, IoT

The XR21B142x family of USB to serial bridge devices for industrial applications, made by Exar, provides a convenient and straightforward way to interface with RS-232 or RS-485 serial networks through USB using a minimum of components and PCB space. The four devices in the range provide 1, 2 or 4 UART channels, or a single-channel UART with native HID driver, respectively. Compliant to the USB 2.0 specification with 12 Mbps data transfer rate, their 512 Byte transmit and receive FIFOs enable a maximum data throughput of 9 Mbps across up to four UART channels. With ratings suited to rugged applications, the ICs feature an internal oscillator, can be powered directly by the USB host, and integrate an LDO.
