## Key Features

Flexible processor selection enables performance/power trade-offs. Scalable SDRAM architecture supports configurations from 64 MB to 384 MB. Full VME-64 compliance with multiple address and data space support ensures compatibility with existing systems. Integrated SCSI controllers provide direct storage connectivity without PMC dependencies. Dual USB ports and comprehensive serial/parallel I/O reduce external interface card requirements.

## Typical Applications

Industrial automation, real-time data acquisition, avionics, medical instrumentation, scientific research systems, and telecommunications infrastructure.

## Compatibility & Integration

PMC expansion architecture enables custom I/O and processing functions. Standard PS/2, USB, and RS232 interfaces support legacy and modern peripherals. VME-64 backplane integration positions this module within larger distributed computing architectures.
