Description
Motorola MVME187-032B
Technical Specifications
- Core Architecture: M88000 RISC family with advanced cache coherency managed by dual CMMUs.
- Memory Subsystem: Configurable ECC DRAM subsystem for maximum data protection.
- I/O Interfaces: Comprehensive serial, parallel, and Ethernet connectivity mapped via the PCCchip2 ASIC.
Functional Features
- System Diagnostics: Extensive built-in hardware diagnostics accessible via the 187Bug System Mode service menu.
- Flexible Booting: Supports disk bootstrap load commands and network booting for flexible deployment.
- High-Speed Networking: Auto-strobe feature on the PCCchip2 optimizes parallel port and peripheral timing.
Application Scenarios
Deployed in semiconductor manufacturing, medical imaging systems, and particle accelerator control where data corruption is unacceptable.
Performance Parameters
- Processing Speed: High-frequency RISC execution with hardware-managed cache for minimal memory latency.
- Reliability: Extremely high Mean Time Between Failures (MTBF) suitable for 24/7 continuous operation.
Material Composition
Utilizes high-Tg flame-retardant PCB substrates and gold-plated VME bus connectors for long-term contact reliability.
Structural Characteristics
Double-high VME module with a conductive front panel that provides EMI shielding and thermal grounding when mated to the chassis.
Working Principle
The MC88100 MPU executes instructions out-of-order where possible, while the CMMUs handle virtual-to-physical memory translation and cache snooping to maintain data coherency across the VME bus.
Installation Requirements
Ensure the VME backplane provides clean power rails. Verify that the board’s VME address jumpers do not conflict with other modules in the chassis.
Usage Precautions
Do not remove the board while the system is powered on unless the chassis explicitly supports hot-swapping. Keep the board away from strong magnetic fields.
