**Form Factor**
• Double-high VME module

## Key Features

• Battery-backed static RAM and real-time clock preserve critical data and timing during power transitions
• Four serial ports enable multi-device connectivity and legacy system integration
• DMA-capable SCSI interface supports high-speed data transfer without processor overhead
• Configurable boot ROM sizes (128 KB or 256 KB) accommodate various firmware images
• Six independent tick timers support concurrent timing operations and interval-based events

## Typical Applications

• Industrial process control and supervisory systems
• Data acquisition platforms in embedded environments
• VMEbus-based test and measurement systems
• Real-time computing and system controllers

## Compatibility & Integration

Designed as a VMEbus module, the MVME197SP integrates into VME architectures supporting the full address and data width spectrum (A16/A24/A32 with D8/D16/D32). Its standardized interface and system controller capability enable both master and slave operation within existing VME backplanes.
