PCA-6154/6154L User's Manual
1.1
Introduction
The PCA-6154/6154L 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-6154/6154L
offers all the functions of an industrial computer on a single board,
half-size CPU card. This card uses an Intel Pentium, Pentium MMX,
AMD K5, AMD K6, AMD K6-2, Cyrix M1 or Cyrix M2 processor. The
card accepts up to 128 MB DRAM. It is also equipped with 512 KB
PB-SRAM 2
nd
level cache.
The PCA-6154/6154L uses a single-chip solution, allowing on-board
DRAM to be shared with the built-in VGA controller. In this configura-
tion, 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
nd
level cache memory,
100/10 Mbps fast Ethernet interface (PCA-6154 only), 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 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-6154/6154L also supports two USB ports and one
fast infrared port.
The PCA-6154/6154L 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 automatical-
ly reset the system or generate an interrupt should the system stop
due to a program bug or EMI.
