XR17L152
3.3V PCI BUS DUAL UART
REV. 1.1.0
GENERAL DESCRIPTION
The XR17L1521 (L152) 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 requirements in communication systems. The global interrupt source register provides a complete interrupt status indication for both channels to speed up interrupt parsing.
