Motorola MVME025 System Controller Module

Product manual:

Motorola MVME025 System Controller Module
Product Overview

Motorola MVME025 is a system controller module based on the VMEbus architecture, belonging to Motorola's early MVME series. Its main function is to serve as the main control unit of the VME bus, responsible for system startup, bus arbitration, clock allocation, and interrupt management. MVME025 is often used in conjunction with MVME CPU modules and I/O boards to provide reliable system level management and bus control functions for embedded real-time systems.
