Description
Motorola MVME166-11A
Technical Specifications:
- Brand: Motorola
- Model: MVME166-11A / MVME16611A
- Architecture: M68000 (68K) CISC architecture
- Firmware System: Equipped with MVME166Bug (166Bug) debugging and diagnostic firmware
Functional Features:
- Powerful Debugging Tools: Built-in 166Bug firmware provides memory display and modification, breakpoint tracing, assembly/disassembly, and Power-On Self-Test (POST) functions.
- System Call Support: Provides low-level services for I/O handling, data conversion, and string operations to user programs via TRAP #15 system calls.
- High Portability: The firmware family features high universality, emphasizing cross-platform portability and ease of maintenance.
Application Scenarios:
Real-time control systems, SCADA, telecommunications network equipment, and system-level evaluation and testing platforms.
Performance Parameters:
Features fast instruction execution cycles and deterministic interrupt response times, meeting hard real-time control requirements.
Material Composition:
Industrial-grade high-density PCB with carefully selected long-life capacitors and resistors, adapting to harsh electromagnetic environments.
Structural Characteristics:
Standard VME single-board computer dimensions, featuring a serial console interface and status indicator lights on the front panel.
Working Principle:
Upon system power-up, the 166Bug firmware first performs hardware integrity self-tests. Subsequently, it receives user commands via the console terminal, loads and executes user programs, and conducts system evaluation or real-time control in a fully controlled environment.
Installation Requirements:
Onboard VME address and interrupt jumpers must be set correctly to prevent resource conflicts with other backplane modules.
Precautions for Use:
Performing low-level firmware debugging or memory modification requires professional M68000 assembly language knowledge. Modifying critical system registers in debug mode is strictly prohibited to prevent system lockups.
