1.1 Introduction
The PCI-6771 all-in-one industrial grade PCI-bus CPU card uses
Intel’s highly acclaimed Celeron® processor or Pentium
®
III
processor, together with the Intel 440BX PCI chipset.
The CPU provides 128 KB (or 256 KB for Pentium III) on-CPU
L2 cache, eliminating the need for external SRAM chips. It has
one PCI EIDE interface for up to two devices and a floppy disk
drive interface for up to two devices. Other features include two
RS-232 serial ports (16C550 UARTs with 16-byte FIFO or
compatible), one enhanced parallel port (supports SPP/EPP/ECP)
and one USB (Universal Serial Bus) port. The PCI enhanced IDE
controller supports Ultra DMA/33 and PIO Mode 4 operation.
This provides data transfer rates of over 33 MB/sec. System Bios
supports boot-up from an IDE CD-ROM, SCSI CD-ROM and LS-
120.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 62-
level Watchdog timer which resets the CPU or generates an
interrupt if a program cannot be executed normally. This enables
reliable operation in unattended environments.
The PCI-6771 offers several impressive industrial features such as
VGA (AGP) controller, two SODIMM slots for a total of 256 MB
RAM memory and a 10/100Base-T networking controller. In
addition, the PCI-6771 series supports a solid state disk (SSD)
using a CompactFlash™ disk that is not as vulnerable to the
hazards of an industrial computing environment. These features
make it an ideal choice for applications that require both high
performance and full functionality.
