Introduction
The PCA-6157 industrial grade CPU card uses Intel's highly
acclaimed Pentium P54C type 75/90/100/120/133/150/166 MHz CPUs
and 82437FX "Triton" chipset. The card works with standard ISA
and/or ISA/PCI bus passive backplanes.
In addition to the Pentium's 16 KB on-chip cache memory, the card
has an extra 256 KB 2nd-level write-back cache. The PCA-6157 also
supports 8 to 128 MB of on-board DRAM. It has two PCI EIDE
interfaces (for up to four devices), a PCI SCSI-II interface, and an
FDD interface (for up to two devices). Other features include two
RS-232 serial ports (16C550 UARTs with 16-byte FIFO or compati-
ble) and one enhanced parallel port (supports EPP/ECP). The card's
high speed PCI EIDE controller supports mode 4 operation, which
provides data transfer rates of over 16 MB/sec. and allows drive
capacities of up to 8.4 GB for connecting tape drives, CD-ROMs,
optical devices, etc.
In addition, the EBM3x-JA has a temperature sensor for the
Pentium CPU. It automatically turns on the CPU cooling fan and
outputs a CPU overheat alarm digital signal when the CPU tempera-
ture exceeds the upper-limit value set by BIOS. This ensures CPU
card reliability and lengthens CPU life.
The PCA-6157's 32-bit passive PCI interface provides burst transfer
speeds of up to 132 MB per second. The interface eliminates data
transfer congestion and improves performance of high bandwidth
applications such as graphics, video and LANs. The card also
provides a standard ISA bus interface for non-PCI adapter cards,
so you can still take advantage of the card's powerful on-board
PCI-EIDE and PCI SCSI-II controller when the card is plugged into
an ISA bus passive backplane. You can also plug the PCA-6157
into a PCI/ISA passive backplane for use with high performance
PCI-bus I/O cards.
The PCA-6157L does not have SCSI chip and temperature sensor.
