Emerson / Motorola MVME2301 VME Processor Module

The Emerson/Motorola MVME2301 is a VME64-compliant processor module designed for real-time control, data acquisition, and communication in industrial and embedded systems. Built on Motorola's PowerPlus Architecture, it combines a 32-bit MPC60x microprocessor (200 MHz MPC603 example) with a 64-bit PCI bus for efficient data throughput. The module features 16 MB ECC DRAM and 5 MB on-board Flash memory, with two 32/64-bit PMC expansion slots supporting both front-panel and P2 I/O connectivity. Integrated 10/100 Mb/s Ethernet and asynchronous serial debug port provide network and diagnostic interfaces. Five timer resources - four 32-bit timers, one 16-bit timer, and one watchdog timer - enable precise timing and system protection. Single VME slot form factor (233.4 mm H × 160.0 mm D × 19.8 mm W) with VME64-optimized interface design minimizes PCI latency. The module integrates into systems requiring deterministic performance across demanding operating environments.
