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.
