Description
Motorola MVME162-531
Technical Specifications
- Processor: High-speed MC680x0 CPU.
- Memory: Up to 8MB interleaved DRAM with parity.
- Controllers: VMEchip2, MCchip, IPIC, Z85230, 82596CA, 53C710.
- Non-Volatile Storage: MK48T08 BBRAM/TOD.
Functional Features
- Maximum Performance: 8MB interleaved memory provides optimal throughput.
- Comprehensive I/O: Combines Ethernet, SCSI, and multiple serial ports on one board.
- Advanced Timing: IPIC and MCchip provide precise interrupt and timer management.
Application Scenarios
Used in radar systems, medical imaging, and high-speed network switches.
Performance Parameters
- Read/Write Operations: Reads to LCSR and GCSR can be 8, 16, or 32 bits; byte reads should be used for interrupt vectors.
- Timeout Handling: Accesses to unmapped areas terminate with a TEA signal if the local bus timer is enabled.
Material Composition
Ruggedized industrial PCB with high-temperature components.
Structural Characteristics
6U VME board with extensive front panel LED diagnostics.
Working Principle
The MC680x0 processor coordinates all system activities, utilizing the MCchip for memory refresh and the VMEchip2 for backplane communication. Software must ensure proper initialization cycles.
Installation Requirements
Verify VME chassis compatibility and power supply ratings before installation.
Usage Precautions
Always observe lithium battery safety precautions. Do not mix new and old batteries or use different models.
