Product Description
The PI7C8952 is
a
PCI® Dual 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. The
PI7C8952 provides standard PCI® connection, and it is fully
compliant with 32-bit PCI Bus 2.3 specifications. The bridge
supports two 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 level, I/O mapping and memory mapping,
IrDA (Infrared Data Association) encoder/decoder, 8 general
purpose I/O and 16-bit timer counter. The PI7C8952 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.
