Motorola MVME6100 high-performance PowerPC VME single board computer with MPC7457 processor, supports 2eSST VMEbus, widely used for industrial control, aerospace and legacy automation system upgrade spare part.

Product Overview

• Part No: MVME6100
• Brand: MOTOROLA (Motorola Computer Group, later Emerson)

• Category: 6U VMEbus Single Board Computer (SBC) MVME6100 is a single-slot 6U VME single-board computer built around MPC7457 PowerPC processor and Marvell MV64360 system controller, equipped with Tundra Tsi148 VME bridge chip. It is the first generation VME SBC supporting 2eSST high-speed VME transmission, delivering significantly improved VMEbus throughput compared with traditional VME boards. The platform provides abundant onboard interfaces and dual PMC expansion slots, supporting VxWorks, Linux and other real-time operating systems. Widely deployed in industrial automation, power control, aerospace, particle accelerator control and legacy VME system renovation projects, and serves as critical maintenance spare for existing VME rack control systems.
