Introduction

The PCA-6276 all-in-one industrial grade CPU card uses two of
Intel's highly acclaimed Celeron™ processors, together with the Intel
440BX PCI chipset. The card works with standard ISA or
PCI/ISA-bus passive backplanes.
The CPU provides 128 KB on-CPU L2 cache, eliminating the need
for external SRAM chips. It has two PCI EIDE interfaces (for up to
four devices) and a floppy disk drive 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
SPP/EPP/ECP) and one USB (Universal Serial Bus) port. The PCI
enhanced IDE controller supports Ultra DMA/33 and PIO Mode 4
operation. This provides data transfer rates of over 33 MB/sec.
System BIOS supports boot-up from an IDE CD-ROM, SCSI
CD-ROM 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 operation
in unattended environments.
The PCA-6276 offers several impressive industrial features such as a
VGA (AGP) controller, a 10/100Base-T networking controller, four
DIMM slots for a total of 1 GB RAM memory, and an ISA High
Drive. All these make it an ideal choice for applications that require
both high performance and full functionality.
