2 PCI Comm Card Series User's Manual
Description
The PCI Local Bus is a high-performance bus that provides a proces-
sor-independent data path between the CPU and high-speed peripher-
als. PCI is a robust interconnect mechanism designed specifically to
accommodate multiple high performance peripherals for series
communication, SCSI, LAN, etc.
Advantech serial communication cards leverages the " Plug and Play
" capability defined in the PCI 2.1 bus specification. The board
requires only one PCI slot within the personal computer and provides
independent serial channels. All channels are addressed in a continu-
ous 32 byte I/O block for simplified software access. And, all channels
may also share one PCI interrupt. An interrupt status register is
available for determining the interrupt source.
The Advantech PCI communication card comes standard with
16PCI954 UARTs containing 128 byte FIFOs which are available as
an option. These upgraded FIFOs greatly reduce CPU overhead and
are an ideal choice for heavy multitasking environments.
16PCI954
The 16PCI954 is a high performance Quad UART with an on-chip PCI
interface. Targeted at PCI-based serial and parallel expansion cards,
PCI-architecture computer systems and embedded applications, the
16PCI954 integrates a PCI bus interface together with four of 16C950
high performance UARTs, a bi-directional parallel port and a local
bus bridge function. This single-chip solution replaces five or more
integrated circuits used in today products, giving performance, cost
and size advantages for new designs.
