The CPX750HA offers many standard features desirable in a CompactPCI
computer system, such as:
❏ PCI Bridge and Interrupt Controller
❏ ECC Memory Controller chipset
❏ 5MB to 9MB of linear FLASH memory
❏ IDE CompactFlash memory
❏ 16MB to 256MB of ECC-protected DRAM
❏ Interface to a CompactPCI bus
❏ Several I/O peripherals
The I/O peripheral interfaces present on the onboard PCI bus include:
❏ One 10/100-BASE-T Ethernet interface
❏ One USB host controller
❏ One SA master/slave interface
❏ One Fast EIDE interface
❏ One PMC Slot
Functions provided from the ISA bus are two asynchronous and two
synchronous/asynchronous serial ports, keyboard, mouse, a floppy disk
controller, printer port, a real time clock, and NVRAM.
The CPX750HA interfaces to a CompactPCI bus using a DEC 21154 PCI-
to-PCI bridge device. This device provides a 64-bit primary and a 64-bit
secondary interface allowing full 64-bit data access between CompactPCI
bus devices and the host/PCI bridge. This bus is capable of driving seven
CompactPCI slots.
Another key feature of the CPX750HA is the PCI (Peripheral Component
Interconnect) bus. In addition to the onboard local bus peripherals, the PCI
bus supports an industry-standard mezzanine interface, IEEE P1386.1
PMC (PCI Mezzanine Card). PMC modules offer a variety of possibilities
for I/O expansion.
