Application Scenarios
Designed to meet the stringent demands of military, aerospace, industrial automation, and medical equipment applications.
Performance Parameters
- Network Interface: Ethernet transceiver interface with 32-bit PCI local bus DMA.
- Storage Interface: 8-bit or 16-bit fast SCSI-2 bus interface.
- Timers: Four 32-bit timers and one watchdog timer.
Material Composition
Constructed with industrial-grade, high-Tg printed circuit boards (PCBs) utilizing high-reliability BGA and PLCC packaging for critical components.
Structural Characteristics
Standard 6U VME form factor with a dedicated VME slot that remains available even when configured with a PMC module.
Working Principle
The PowerPC 750 processor manages local PCI peripherals and communicates with the VME backplane through bridge controllers, executing real-time operating system instructions upon boot.
Installation Requirements
Must be securely inserted into a compatible 6U VME chassis backplane, ensuring proper alignment of P1 and P2 connectors.
Usage Precautions
Strictly observe electrostatic discharge (ESD) protocols during handling. Never hot-swap the module while the system is powered on.
