Emerson / Motorola MVME2434 VME Processor Module

The Emerson/Motorola MVME2434 is a VME processor module built on Motorola’s PowerPlus II Architecture, delivering real-time control and data acquisition in a single VME64 slot. It combines a PowerPC 750 microprocessor with dual PCI Mezzanine Card (PMC) expansion slots, on-board memory, and integrated I/O interfaces—all designed for demanding industrial and embedded applications requiring flexible, high-performance computing within constrained form factors.

## Key Features

Dual PMC slots enable modular I/O expansion without redesign. ECC SDRAM protects against single-bit errors in mission-critical applications. Configurable VMEbus master/slave operation and DMA support high-throughput data transfers. Multiple clock speeds accommodate performance-to-power tradeoffs. Battery-backed NVRAM preserves real-time data across power cycles.

## Typical Applications

Real-time control systems, distributed data acquisition networks, industrial process automation, embedded military and aerospace platforms, and legacy VME system upgrades.

## Compatibility & Integration

Backward compatible with existing VME64 card cages. PMC expansion supports IEEE P1386.1 standard interfaces. Integrates with systems requiring PowerPC processors and PCI-based peripheral expansion.
