Introduction

The PCA-6151 is a cost-effective, all-in-one single board Pentium
CPU card which can release Pentium's full potential and provide
unprecedented performance compared to current 64-bit processor
board. The PCA-6151 offers all the functions of an industrial
computer on a single board, half-size CPU card. This card uses a
Pentium, AMD K5 CPU or Cyrix M1 and can have up to 64 MB
nd
DRAM. It also supports PB-SRAM 2 level cache size from 256KB
to 512KB through an on board COAST module.
The PCA-6151 utilizes a two-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 insures efficient memory allocation while substantially
reducing the overall system cost.
On-board features include one RS-232 port, one RS-232/422/485 port,
one multi-mode parallel (ECP/EPP/SPP) port, a floppy drive control-
ler and a keyboard & PS/2 mouse interface. The built-in high speed
PCI IDE controller supports both PIO and bus master modes. Up to
two IDE devices can be connected, including large hard disks,
CD-ROM drives, tape backup drives and other IDE devices.
The PCA-6151 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.
