Product Description
   The PI7C8954 is a PCI® Quad UART (Universal Asynchronous Receiver-Transmitters) I/O Bridge. It is specifically designed to meet various system requirements of high performance and lead (Pb) -free. The bridge can be used in a wide range of applications such as Remote Access Servers, Automation, Process Control, Instrumentation, POS, ATM and Multi-port RS232/RS422/RS485 Cards.
