Product Description  
The PI7C9X7954 is a PCI Express® Quad UART (Universal  
Asynchronous Receiver-Transmitters) I/O Bridge. It is  
specifically designed to meet the latest system requirements  
of high performance, lead (Pb) -free and reduced package  
sizes. 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. The PI7C9X7954 provides one  
x1 PCIe® (dual simplex 2.5 Gbps) uplink port, and it is fully  
compliant with PCI express 1.1 and PCI® power  
management 1.2 specifications. The bridge supports four  
high performance UARTs, each of which supports Baud rate  
up to 15 Mbps in asynchronous mode. The UARTs support  
in-band and out-band auto flow control, arbitrary trigger I/O  
mapping and memory mapping. The PI7C9X7954 is fully  
software compatible with 16C550-type device drivers and  
can be configured to fit the requirements of RS232, RS422  
and RS485 applications. The EEPROM interface is provided  
for system implementation convenience. Some registers can  
be pre-programmed via hardware pin settings to facilitate  
system initialization. For programming flexibility, all of the  
default configuration registers can be overwritten by  
EEPROM data, such as sub-vendor and sub-system ID.
