Emerson / Motorola MVME7100-0171 VMEbus Single-Board Computer

The Emerson/Motorola MVME7100-0171 is a VMEbus single-board computer built on the Freescale MPC864xD System-on-Chip architecture, delivering dual PowerPC® e600 cores operating at up to 1.3 GHz. This SBC integrates 2eSST VMEbus protocol support with 320 MB/s transfer rates - up to 8x faster than VME64 - while maintaining full backward compatibility with legacy VME64 and VME32 systems. The platform combines substantial on-board memory, multi-port Gigabit Ethernet, and extensive I/O expansion via PMC-X and XMC slots, making it well-suited for industrial automation, defense, aerospace, and telecommunications deployments where long-term reliability and protected system investment matter.
