Product:
PCI Express
Octal UART I/O Bridge
Part Numbers: PI7C9X7958
Product Description
The PI7C9X7958 is a PCI Express
Octal 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 PI7C9X7958 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 eight
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 PI7C9X7958 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.
