Description
Motorola MVME162-012
Technical Specifications:
- Brand: Motorola
- Model: MVME162-012
- Processor: MC68040 Enhanced 32-bit Microprocessor
- Bus Architecture: VMEbus (ANSI/IEEE 1014-1987), supporting A32/D64
Functional Features:
- Excellent VME Compatibility: Strictly compliant with VMEbus standards, supporting block transfers for seamless integration into existing VME systems.
- High-Speed DMA Support: Provides high-performance Direct Memory Access for VMEbus D64 and local bus memory burst cycles.
- Rich I/O Expansion: Supports up to four single-width or two double-width IndustryPack modules, maximizing slot utilization.
- Non-Volatile Resources: On-board NVRAM and Real-Time Clock (RTC) ensure critical configurations and fault logs are retained during power loss.
Application Scenarios:
Primarily utilized in semiconductor manufacturing equipment, metallurgical rolling mill control, chemical reactor management, railway transportation subsystems, and defense/aerospace ground test systems.
Performance Parameters:
- Operating Temperature: 0°C to +55°C (Requires forced air cooling)
- Storage Temperature: -40°C to +85°C
- Power Requirements: +5V DC (3.5A typical), +12V DC, -12V DC from VME backplane
- Interrupt Response: Hardware-level real-time interrupt controller with response times ≤20μs
Material Composition:
Manufactured with high-purity copper conductors and premium insulating materials. The enclosure offers superior electromagnetic shielding, and the PCB is coated with a strict three-proof conformal coating to resist moisture, salt spray, and dust.
Structural Characteristics:
Standard 6U Eurocard dimensions (approx. 160mm x 233mm). Features P1/P2 backplane connectors, front-panel status LEDs, and physical RESET/ABORT pushbuttons for convenient diagnostics.
Working Principle:
Centered on the MC68040 processor, it utilizes a VMEbus interface ASIC for global control and status register management. Combined with a hardware-level interrupt controller, it achieves microsecond-level real-time responses and precise logic control.
Installation Requirements:
Must be installed in a standard 6U VME chassis using card guides. Requires forced air cooling with a 100 CFM axial fan to ensure unobstructed airflow across the heat sinks.
Usage Precautions:
When replacing the SRAM backup battery (RAYOVAC FB1225), configure the J20 power select jumpers correctly to prevent data loss. Never place a circuit board with an installed battery on a conductive surface.
