Description
Motorola MVME2604-761
Technical Specifications
- Processor: 333 MHz MPC604 microprocessor with on-chip cache and MMU.
- Communication Ports: Multiple EIA-232-D serial ports and a Centronics printer port.
- Storage: Large-capacity on-board shared RAM supporting programmable parity checking.
- Timers: Two 16-bit timers and a watchdog timer.
Functional Features
- Efficient Processing: The combination of on-chip cache and MMU significantly improves multitasking efficiency and memory security.
- Comprehensive Diagnostics: On-board debugger/monitor firmware simplifies system startup and troubleshooting processes.
- Cost Optimization: Achieves peripheral control without additional backplane modules, saving bus slots.
Application Scenarios
Widely used in large PLC systems, robot controllers, production line main control computers, and early telecommunications switching equipment.
Performance Parameters
- Interrupt Levels: 7-level interrupt handling ensuring real-time response for critical tasks.
- Clock System: Battery-backed real-time clock/calendar ensuring continuous time reference.
Material Composition
Industrial-grade multi-layer PCB using high-conductivity copper foil and premium solder mask.
Structural Characteristics
Standard VME 6U module size. Features debug interfaces and status indicator lights on the front panel.
Operating Principle
The MPC604 processor obtains instructions and data via the VME bus, managing serial, parallel, and SCSI devices using on-board peripheral controllers.
Installation Requirements
Ensure P1 and P2 connectors on the VME chassis backplane are free from oxidation or damage. Verify the module is fully seated after installation.
Usage Precautions
Use identical specification lithium coin cell batteries when replacing on-board batteries. In high-interference environments, it is recommended to use shielded I/O transition modules.
