Introduction
®
The PCA-6155V is a cost-effective, all-in-one single board Pentium
processor-based CPU card which can release the Pentium processor's
full potential and provide unprecedented performance compared to
current 64-bit processor board. The PCA-6155V offers all the func-
tions of an industrial computer on a single board, full-size CPU card.
This card uses an Intel Pentium, Pentium MMX, AMD K5, AMD K6,
Cyrix M1 or Cyrix MX processor. The card accepts up to 256 MB
nd
DRAM. It also supports on-board 512 KB PB-SRAM 2
level cache.
The PCA-6155V uses a single-chip solution, allowing on-board
DRAM to be shared with the built-in VGA controller. In this
configuration, the chipset always acts as the arbiter between memory
bus masters. This system ensures efficient memory allocation while
substantially reducing the overall system cost.

On-board features include 512 KB 2
level cache memory, one RS-232
port, one RS-232/422/485 port, one multi-mode parallel (ECP/EPP/SPP)
port, a floppy drive controller and a keyboard and PS/2 mouse inter-
face. The built-in high speed PCI IDE controller supports both PIO and
DMA bus master modes, enabling data transfer rates in excess of 33
MB/second. Up to four IDE devices can be connected, including large
hard disks (up to 8 GB), CD-ROM drives (CD-ROM bootable), tape
backup drives and other IDE devices. The PCA-6155V also supports
two USB ports and one infrared port.
The PCA-6155V also features power management to minimize power
consumption. It complies with the "Green Function" standard and
supports three types of power saving features: Doze mode, Standby
mode and Suspend mode. A watchdog timer can automatically reset
the system or generate an interrupt should the system stop due to a
program bug or EMI.
