PowerMIDAS M5000 VME PowerPC Single Board Computer with onboard Fibre Channel

The PowerMIDAS M5000 Single Board Computers and I/O Controllers are PMC carrier cards optimized for high-performance I/O and designed for engineers wishing to maximize their systems potential for future performance and functionality upgrades.

The PowerMIDAS M5000 provides 2 PMC sites, 3 independent PCI-X buses and options for up to two ports consisting of 2 Gb/s Fibre Channel and/or Gigabit Ethernet without having to sacrifice a PMC slot. These capabilities in conjunction with Processor PMC (PrPMC) and/or I/O devices, allow the PowerMIDAS M5000 to scale and evolve in a wide variety of applications, far beyond what is possible with more traditional carrier boards, I/O boards or single board computers.

The PowerMIDAS M5000 series offers a number of features unique to the VME implementation. The PowerMIDAS M5000 for VME utilizes the AMCC PPC440GX PowerPC CPU core running at 667MHz, 256MB local DDR-SDRAM memory, 32 MB FLASH memory, two 10/100/1000 Mbps Ethernet connections, 10/100 Mbps Ethernet connection and two serial connections (RS-232 or RS-422).

In addition to the standard PCI-X buses, the PMC sites include the following connections:

• PMC to VME P2: The P4 connector of the PMC site #1 is connected to the VME P2 connector as described in the VITA 44S standard proposal (Host PMC Pn4 Signal Routing for Differential I/O, document issued by the Study Group) and the ANSI/VITA 35-2000 standard (PMC-P4 pin out mapping to VME P0 and VME64x-P2).
• PMC to VME P0: The P4 connector of the PMC site #2 is connected to the VME P0 connector as described in the ANSI/VITA 35-2000 standard (PMC-P4 pin out mapping to VME P0 and VME64x-P2).

The extension subsystem is composed of VME, RACE++ and mezzanine interfaces. All the devices are located on a private 64-bit 33MHz 5V signaling PCI only segment. This PCI segment is called the quaternary PCI segment. A PCI6540 universal PCI-X to PCI-X bridge connects the quaternary PCI segment with the tertiary PCI-X segment. The Tundra Universe IID PCI-to-VME bridge is a PCI only component which provides VME accesses. The Mercury PXB++ PCI-to-RACE++ bridge is a device that enables operation in RACE++ systems. The mezzanine connector provides access to a mezzanine board compatible with the previous family of PowerMIDAS boards (via a spacer). A set of two connectors provides accesses to one PCI bus (64-bit, 33MHz, 5V signaling) and control signals.
