4-level requester, 7-level interrupter, and

7-level interrupt handler for VMEbus

Low-power, high-performance microprocessor suitable for a variety of

applications

The MVME2400 series of VME boards provides the performance of Motor

ola’s PowerPlus II Architecture and the ability to be fully customized to satisfy

your application needs with two PCI Mezzanine Cards (PMCs). The flexibility

of the MVME2400 provides an excellent base platform that can be quickly

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

Utilizing Motorola’s low-power, high-performance PowerPC 750 microproces

sors, the Peripheral Component Interconnect (PCI) bus for the on-board

peripherals, processor/memory bus to PCI bus bridge, and a VME interface,

the MVME2400 processor modules pack optimum levels of flexibility and per

formance into a single VME slot.

IEEE P1386.1 Compliant PMC Slots

The MVME2400 features dual PMC ports with support for

both front-panel and P2 I/O. P2 I/O-based PMCs which follow

the PMC committee recommendation for PCI I/O when using

the VME64 extension connector will be pin-out compatible

with the MVME2400.

In addition to providing high-performance expansion I/O, the

IEEE P1386.1 compliant PMC ports form a common architec

ture for future generations of products. Changing I/O require

ments can be satisfied by simply replacing PMCs while

reusing the same base platform, reducing the long-term cost

VME64 Extension Connector

To maximize the capabilities of the MVME2400. 5-row 160

pin DIN connectors replace the 3-row 96-pin connectors his

torically used on VME for P1 and P2. Two rows, Z and D,

have been added to the VME P1/J1 and P2/J2 connectors

providing a user with additional I/O. The VME64 extension

connector is 100% backward compatible with existing VME

card systems.

PowerPlus Architecture

A second-generation architecture, PowerPlus II Architecture

is a processor and bus architecture fully optimized to get the

maximum performance from the PowerPC microprocessor

family, the PCI bus, and the VMEbus. Features added to the

original PowerPlus Architecture include support for 100 MHz

local bus operation, and utilization of synchronous DRAM

(SDRAM) technology. The outstanding performance of VME

processor boards based on the PowerPlus II Architecture is

not due to a single factor. A number of elements in the design

of the PowerPlus II Architecture contribute to its outstanding

performance including the Processor/Memory subsystem,

high-speed local bus, optimally decoupled architecture,

decoupling the processor from PCI, and the advanced VME

interface which reduces PCI delays.
