Description
Motorola MVME2604-4461
Technical Specifications
- Processor: 400 MHz MPC604.
- Memory: 0–512 MB ECC DRAM.
- Storage: 9 MB Flash.
- Architecture: PowerPC with VME64 interface.
Functional Features
- Advanced Memory Protection: ECC circuitry detects and corrects single-bit memory errors.
- Flexible Boot Options: Supports booting from Flash, network, or VME backplane.
- Integrated Peripherals: On-board Ethernet controller and SCSI interface.
- Global Control Status Register (GCSR): Enables inter-processor communication and status monitoring.
Application Scenarios
Deployed in nuclear power plant instrumentation, railway signaling systems, and automated test equipment (ATE).
Performance Parameters
- Thermal Limits: 0°C to 55°C inlet air temperature.
- Power Supply Tolerance: ±5% on all DC voltage rails.
Material Composition
Multi-layer PCB with controlled impedance routing for high-speed PCI and VME signals.
Structural Characteristics
Base board depth is 6.3 in. (160 mm). Front panel depth extends to 7.4 in. (188 mm) to accommodate standard I/O connectors.
Working Principle
The MPC604 executes instructions fetched from cache or memory, utilizing DMA engines to transfer data between VME bus, PCI devices, and local DRAM without CPU intervention.
Installation Requirements
Verify the backplane slot is rated for 6U VME64. Ensure adequate clearance behind the board for rear transition modules if applicable.
Usage Precautions
Do not modify board jumpers unless specified in the hardware manual. Replace the CMOS battery if the system fails to retain time/date settings.
