The MVME2400 series VME boards offer the performance of Motor ola’s PowerPlus II architecture and can be fully customised to meet the needs of

your applications requiring two PCI mezzanine cards (PMCs). Flexibility

The MVME2400 provides an excellent base platform that can be quickly

and easily customised for a variety of industry-specific applications.

Utilising Motorola’s low-power, high-performance PowerPC750 microprocessor, www.abb-drive.com the Peripheral Component Interconnect (PCI) bus for onboard

peripherals, processor/memory bus to PCI bus bridges and VME interfaces, the

The MVME2400 processor module packages optimal levels of flexibility and performance into a single VME slot

IEEE P1386.1-compliant PMC slot The MVME2400 features dual PMC ports supporting

front panel and P2 I/O. The following are P2 I/O based PMCs

VME64 expansion connector will be compatible with pin-outs

MVME2400 in addition to providing high performance expansion I/Os

IEEE P1386.1 compliant PMC ports form a common architecture for future generations.

Simply replacing the PMC meets changing I/O needs while reusing the same base platform, reducing long-term cost ownership.

VME64 Expansion Connector To maximise the functionality of the MVME2400. a 5-row 160-pin DIN connector replaces its 3-row 96-pin connector on the VME for P1 and P2.

Two rows of Z and D have been added to the VME P1/J1 and P2/J2 connectors to provide additional I/O for the user.

The VME64 expansion connector is 100% backwards compatible with existing VME card systems.

PowerPlus Architecture Second Generation Architecture, PowerPlus II Architecture

is a processor and bus architecture fully optimised for maximum performance on PowerPC microprocessors.

family, PCI bus and VMEbus.

Features added to the original PowerPlus architecture include support for 100 MHz

local bus operation and synchronous DRAM utilisation (SDRAM) technology.

VME’s superior performance on processor boards based on the PowerPlus II architecture is

not due to a single factor. Several elements of the PowerPlus II architecture in the design contribute to the

performance, including the processor/memory subsystem, the

high-speed local bus, an optimal decoupling architecture that

decoupling the processor from PCI, and advanced VME interfaces to reduce PCI latency.
