1.1 Introduction
The PCA-6176 series all-in-one industrial grade CPU card uses
Intel's highly acclaimed Pentium
®
II/III processor, together with the
Intel 440BX 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.
System BIOS supports boot-up from an IDE CD-ROM, SCSI
CD-ROM, ZIP 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 63-level
watchdog timer, which resets the CPU or generates an interrupt if a
program cannot be executed normally. This enables reliable opera-
tion in unattended environments.
The PCA-6176 series offers several impressive industrial features
such as a VGA (AGP) controller, a PCI Ultra2 SCSI controller, a
10/100Base-T networking controller, and an ISA High Drive. All
these make it an ideal choice for applications that require both high
performance and full functionality.
