Exar Corporation XR17C152
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.| Part No. | XR17C152 |
