Description
Motorola MVME165-02
Technical Specifications
- Processor: Motorola MC68040 or MC68060 microprocessor.
- Memory: Onboard DRAM with parity protection, expandable via memory mezzanine modules.
- I/O Controllers: Integrated VMEchip2, MCchip, and standard serial/LAN controllers.
- Timekeeping: Battery-backed RAM and Time-of-Day (TOD) clock.
Functional Features
- System Controller: Full VMEbus system controller with arbitration and interrupt handling.
- Memory Protection: Hardware parity checking with bus exception generation.
- Boot Flexibility: Supports booting from EPROM, Flash, or network TFTP.
- Debug Support: Onboard firmware monitor for hardware diagnostics.
Application Scenarios
Widely deployed in legacy industrial automation, telecommunications switching, and aerospace test equipment.
Performance Parameters
- Data Width: Supports 8, 16, and 32-bit VMEbus data transfers.
- Clock Speed: Operates at high frequencies for the 680×0 architecture (typically 25MHz to 50MHz).
Material Composition
Industrial-grade multi-layer PCB with gold-plated VME edge connectors and high-reliability through-hole and SMT components.
Structural Characteristics
Standard 6U Eurocard VME dimensions. Features front panel status LEDs, ABORT, and RESET switches.
Working Principle
The MC680x0 processor executes code from local memory, utilizing the MCchip for local bus control and DRAM refresh, and the VMEchip2 for VMEbus arbitration and address translation.
Installation Requirements
Insert into a 6U VME backplane. Ensure proper alignment of P1 and P2 connectors before applying insertion force.
Usage Precautions
Observe strict ESD precautions. Verify that the onboard lithium battery is not depleted before first use. Do not operate without adequate chassis airflow.
