XR21B1421 Description

General .
The XR21B1421 is an enhanced Universal Asynchronous Receiver and Transmitter (UART) bridge to HID class USB interface.

XR21B1421 Features

* ±15kV ESD on USBD+/USBD
* USB 2.0 Compliant, Full-Speed (12Mbps)
* Unique pre-programmed USB serial number
* Internally generated 48MHz core clock
* Enhanced UART features
* Baud rates up to 12 Mbps
* Fractional Baud Rate Generator
* 5

XR21B1421 Applications

* The XR21B1421 uses the native OS HID driver using HID reports. The HID reports perform a variety of functions, including device configuration, transmitting and receiving UART data, and programming of the on-chip OTP. Exar provides a . dll as an easy to use programming interface to the HID reports. T
