Motorola MVME162-213 Double-High 6U VMEbus Single Board Computer (SBC)

Motorola MVME162-213 is a classic double-height VME single-board computer originally developed by Motorola Embedded Division, later inherited by Emerson Embedded Systems. 

It serves as the master CPU controller for legacy VME rack-based industrial control systems, executing real-time logic calculation, field I/O data acquisition, VME bus arbitration, 

peripheral communication scheduling and closed-loop control algorithm operation.

This board adopts Motorola MC68040 / MC68LC040 32-bit microprocessor architecture, equipped with parity-protected DRAM, battery-backed SRAM and TOD real-time clock to 

prevent configuration data loss after power failure. Integrated abundant serial, Ethernet and SCSI peripheral interfaces, it supports IndustryPack expansion modules for flexible function 

expansion. Widely deployed on early-generation gas/steam turbine control systems, power plant DCS, offshore platform control cabinets and aerospace test equipment, it is a core maintenance 

replacement spare part for overhaul and troubleshooting of aging VME architecture control systems worldwide.
