The Emerson/Motorola MVME6100 is a VME single-board computer built on the PowerPC MPC7457 processor running at 1.267 GHz, designed for industrial, defense, and aerospace applications requiring real-time control, data acquisition, and communication. It delivers a practical VMEbus bandwidth of 320 MB/s via the Tundra Tsi148 interface chip and supports migration from legacy MVME systems while providing contemporary processing and I/O capabilities.

## Key Features
• Jumper-configurable P2 I/O modes: PMC (backward compatible with MVME2300/2400 and MVME5100/5500) and IPMC (legacy MVME761/MVME712M module support)
• 133 MHz DDR memory bus
• Flexible serial port configuration via SIMs
## Typical Applications
Real-time embedded systems, industrial control platforms, aerospace data processing, defense communications infrastructure, and legacy VME system upgrades.
## Compatibility & Integration
The MVME6100 maintains backward compatibility with existing VMEbus architectures while supporting modern PMC-X expansion and dual Gigabit Ethernet for network-centric deployments. IPMC mode enables integration of legacy I/O modules for systems requiring UW-SCSI, parallel, and extended serial connectivity.
