Description
Motorola MVME162-223
Technical Specifications:
- Brand: Motorola
- Model: MVME162-223
- Processor: 25MHz MC68LC040 (no FPU) or MC68040 (with FPU)
- Memory: 1MB, 4MB, or 8MB Parity-Protected DRAM; 512KB Battery-Backed SRAM
Functional Features:
- Powerful Computing Core: Features a 32-bit enhanced microprocessor with an 8KB cache and Memory Management Unit (MMU) for efficient real-time data processing.
- Non-Volatile Storage: Equipped with 1MB Flash memory and 8K x 8 NVRAM to ensure firmware and critical configurations are safely retained during power loss.
- Rich I/O Expansion: Supports up to four MVIP IndustryPack interfaces, accommodating up to four single-width or two double-width modules while occupying only a single VME slot.
- Multiple Timers: Incorporates six 32-bit timers and a programmable watchdog timer to guarantee real-time response and system self-recovery.
Application Scenarios:
Widely utilized in semiconductor manufacturing equipment, industrial automation production lines, Distributed Control Systems (DCS), data acquisition systems, and high-reliability real-time control networks.
Performance Parameters:
- Serial Communication: Two serial ports (EIA-232-D and EIA-232-D/EIA-530) driven by a Zilog Z85230 controller.
- Optional Interfaces: Supports optional DMA-enabled SCSI bus interface and 10Base-T LAN Ethernet transceiver interface.
- Bus Support: Functions as a VMEbus system controller, supporting A24/A32 addressing and D8/D16/D32 data transfers.
Material Composition:
Constructed using industrial-grade, high flame-retardant PCB materials. Key electronic components undergo strict derating design, and the board is coated with a three-proof conformal coating to effectively resist moisture, salt spray, and dust.
Structural Characteristics:
Standard 6U Eurocard dimensions (approximately 233mm x 160mm x 17mm) with standard VME P1/P2 backplane connectors. The front panel features status indicator LEDs and physical RESET/ABORT buttons for convenient field diagnostics.
Working Principle:
Centered on the MC68040 microprocessor, it utilizes a VMEbus interface ASIC to manage Global Control and Status Registers (GCSR). Combined with hardware-level DMA and interrupt controllers, it achieves microsecond-level real-time interrupt responses and executes complex control algorithms.
Installation Requirements:
Must be installed in a standard 6U VME chassis using card guides. A forced air cooling system is mandatory, ensuring 30-50 LFM of airflow per slot to maintain the operating temperature between 0°C and 70°C.
Usage Precautions:
Always wear an anti-static wrist strap before handling. Inserting or removing the module while the system is powered on is strictly prohibited. When replacing the on-board SRAM backup battery, configure the power jumpers correctly to prevent data loss.
