Description
Motorola MVME177-002
Technical Specifications
- Processor: MC68060 32-bit microprocessor.
- Memory: 4/8/16/32/64/128/256 MB of ECC-protected DRAM.
- Storage: 4 MB of Flash memory, two EPROM sockets, and 8KB of static RAM with a time-of-day clock and battery backup.
- Interfaces: Ethernet transceiver, four EIA-232-D serial ports, and a SCSI bus interface with DMA.
Functional Features
- Data Integrity: ECC-protected DRAM ensures reliable operation in high-noise industrial environments.
- Flexible Boot Options: Supports mixed EPROM/Flash modes or an all-Flash mode configured via the FLASHJP jumper (J8).
- Advanced Bus Control: Integrates the VMEchip2 ASIC for programmable map decoders, DMA control, and tick timers.
Application Scenarios
Ideal for aerospace testing, defense radar systems, telecommunications switching, and high-end industrial automation.
Performance Parameters
- Bus Interface: 16/A24/A32/D8/D16/D32/D64 VMEbus master/slave interface.
- Timers: Four tick timers, a watchdog timer, and additional timers provided by the VMEchip2 ASIC.
- Memory Map: Flash/EPROM appears at address $00000000 following a local bus reset.
Material Composition
Constructed with multi-layer industrial-grade PCBs. Critical components are rigorously screened for high electromagnetic interference (EMI) immunity.
Structural Characteristics
Double-high VME form factor (9.2 in. height, 0.8 in. width, 6.3 in. depth). Features a conductive front panel bonded to connectors for optimal grounding and shielding.
Working Principle
Upon power-up, hardware automatically maps the EPROM or Flash to address $0. The MC68060 processor executes boot code, initializes the VMEchip2 ASIC, and loads the real-time operating system.
Installation Requirements
Must be installed in a compliant VME chassis. Front panel screws must be properly tightened, and conductive chassis rails must be connected to earth ground to ensure FCC Class A compliance.
Usage Precautions
Shielded cables are mandatory on all external I/O ports, with shields connected to earth ground via the metal shell. Always observe strict ESD protocols during handling.
