Description
Motorola MVME2700-1251A
Technical Specifications
- CPU: 233 MHz MPC750 PowerPC.
- DRAM: 16 MB – 256 MB ECC.
- Flash: 8 MB onboard + 1 MB socketed.
- L2 Cache: 1 MB backside.
Functional Features
- VMEbus Interface: Full system controller with local-VME bidirectional interface.
- Serial Ports: 2-3 async, 1-2 sync/async.
- Legacy I/O: PC87308 SIO for keyboard/mouse, floppy, parallel.
- Data Protection: 8KB NVRAM with battery backup.
Application Scenarios
Process control, robotics, traffic management, power grid monitoring, test & measurement.
Performance Parameters
- PCI Bus: 32/64-bit local bus with PMC support.
- Timers: 4x 32-bit programmable + 1x watchdog.
- DMA: A16/A24/A32, D16/D32/D64 fast DMA.
Material Composition
High-Tg multi-layer PCB with industrial-grade screened components and high-standard soldering.
Structural Characteristics
Front panel: ABORT/RESET buttons, J1 for speaker/remote reset. High-density VME edge connectors.
Working Principle
MPC750 superscalar architecture enables instruction-level parallelism. Falcon chipset manages registers; PC87308 handles low-speed I/O.
Installation Requirements
Ensure chassis grounding. Use transition modules for external connections.
Usage Precautions
Use only certified replacement parts. Exercise caution near CRT/high-voltage circuits. Do not block ventilation during operation.
