Description
Motorola MVME2604-4441
Technical Specifications
- Processor: 400 MHz MPC604.
- Memory Capacity: 0–512 MB ECC DRAM.
- Non-Volatile Storage: 9 MB Flash.
- Bus Interface: VME64 / PCI Local Bus.
Functional Features
- Scalable Memory Architecture: Supports up to 512 MB of ECC RAM for large data buffering.
- Comprehensive I/O: Integrated Ethernet, SCSI, and multiple serial ports.
- System Controller Capable: Can act as the VME system controller managing bus arbitration.
- Watchdog Timer: Hardware watchdog ensures system recovery from software lockups.
Application Scenarios
Used in semiconductor manufacturing equipment, medical imaging systems, and distributed control systems (DCS).
Performance Parameters
- Operating Temperature: 0°C to 55°C with forced-air cooling.
- Storage Temperature: -40°C to +85°C.
- Humidity Tolerance: 5% to 90% non-condensing.
Material Composition
Industrial-grade FR4 PCB with gold-plated VME connector pins for enhanced corrosion resistance and signal integrity.
Structural Characteristics
Double-high VME form factor. Base board dimensions are 9.2 inches in height and 6.3 inches in depth, expanding to 10.3 inches height with the front panel.
Working Principle
Upon power-up, the board executes its firmware to perform POST (Power-On Self-Test), initializes the MPC604 CPU and PCI bridge, and loads the real-time OS from Flash or network.
Installation Requirements
Align the board carefully with the VME backplane connectors before applying insertion force. Secure the board using the chassis ejector handles.
Usage Precautions
Do not obstruct the front panel ventilation holes. Verify backplane power sequencing before inserting the board.
