Introduction

The PCA-6175 industrial grade CPU card uses Intel's highly
®
acclaimed Pentium II processor and Intel 440LX PCI chipset. The
card works with standard ISA or PCI/ISA-bus passive backplanes.
The CPU provides 512 KB on-chip L2 cache, eliminating the need
for external SRAM chips. It has two PCI EIDE interfaces (for up to
four devices), and an FDD 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
EPP/ECP), and support for two USB (Universal Serial Bus) ports.
The PCI BUS Master IDE controller supports Ultra DMA/33
operation. This provides data transfer rates of over 33 MB/sec, and
allows drive capacities up to 8.4 GB. System BIOS supports boot-up
from an IDE CD-ROM.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 63-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.
