General Description

The XR17C1521 (152) is a monolithic dual PCI Bus Universal Asynchronous Receiver and Transmitter (UART) in Exar’s PCI Bus UART family.

The device is designed to meet today’s 32-bit PCI Bus and high bandwidth requirement in communication systems.

The global interrupt source register provides a complete interrupt status indication for both channels to speed up interrupt parsing.
