Description
Motorola MVME162-520
Technical Specifications
- Processor: Advanced MC680x0 microprocessor.
- Memory Architecture: Supports interleaved DRAM for 4MB and 8MB options.
- Peripheral Integration: Zilog Z85230 SCC, Intel 82596CA Ethernet, NCR 53C710 SCSI.
- System Timing: MK48T08 BBRAM/TOD Clock.
Functional Features
- High-Speed Memory: Interleaved DRAM architecture maximizes CPU data throughput.
- Robust Networking: Integrated 10Base-T Ethernet for seamless network integration.
- Mass Storage: Onboard SCSI controller supports high-speed disk and tape drives.
Application Scenarios
Deployed in network routers, data acquisition systems, and process control servers.
Performance Parameters
- Bus Access: Writes to the Local Control and Status Register (LCSR) must be 32 bits.
- Serial Communications: Port commands to the 82596CA must be written as two 16-bit writes (upper word first).
Material Composition
Industrial-grade multi-layer PCB with high-reliability BGA and QFP components.
Structural Characteristics
6U VME single-board computer with comprehensive front panel connectivity.
Working Principle
The processor utilizes the MCchip for local memory and peripheral control, and the VMEchip2 for VMEbus arbitration. The system relies on onboard refresh circuitry for DRAM maintenance.
Installation Requirements
Ensure proper backplane termination and stable power supply (+5V, +12V, -12V).
Usage Precautions
Do not apply solder directly to the MK48T08 battery. Always check proper polarity when replacing components.
