Motorola MVME3100 VMEbus Single Board Computer (SBC)

Motorola MVME3100 is a 6U single-slot VME bus industrial mainboard originally developed by Motorola (later acquired by Emerson Embedded Systems), 

belonging to the classic MVME series embedded controller family. It adopts Freescale MPC8540 PowerQUICC III SoC processor (PowerPC e500 core), 

serves as the central processing master controller for legacy VME rack systems, responsible for system logic operation, field I/O data acquisition, bus scheduling, 

network communication and real-time task computing.

It supports high-speed 2eSST VME bus transmission, dual PMC expansion slots for function module expansion, matched with rear transition module MVME721 to 

realize rear-panel wiring I/O. Widely deployed in power plant DCS, nuclear safety systems, oil & gas ESD protection, aerospace test equipment, military embedded control cabinets; 

it is a mainstream maintenance spare part for upgrading and overhauling old VME architecture critical control systems.
