Chapter 1 General Information
1.1 Introduction
The PCI-6870 all-in-one industrial grade PCI-bus CPU card uses
Intel’s highly acclaimed Celeron
®
processor or Pentium
®
III
processor, together with the Intel 815E PCI chipset.
The CPU provides 128/256 KB (or 256/512 KB for Pentium III) on-
CPU L2 cache, eliminating the need for external SRAM chips. It
has two PCI EIDE interfaces for up to four devices and a floppy
disk drive interface for up to two devices. Other features include
two serial ports (16C550 UARTs with 16-byte FIFO or compatible),
one enhanced parallel port (supports SPP/EPP/ECP) and two USB
(Universal Serial Bus) ports. The PCI enhanced IDE controller
supports Ultra DMA100, Ultra DMA33 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, USB devices, 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-6870 offers several impressive industrial features such as
VGA (AGP) controller, one DIMM slot for up to 512 MB RAM
memory and a 10/100Base-T Ethernet controller. In addition, the
PCI-6870 series supports a solid state disk (SSD) using a
CompactFlash
TM
. Type II 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.
