Description
Motorola MVME162-312
Technical Specifications
- Processor: High-performance MC680x0 series microprocessor.
- Memory: Supports onboard DRAM options (1MB, 4MB, 8MB) with parity protection.
- I/O Controllers: Integrated VMEchip2, MCchip, Zilog Z85230 serial controller, Intel 82596CA LAN controller, and NCR 53C710 SCSI controller.
- Timekeeping: MK48T08 BBRAM/TOD Clock.
Functional Features
- Comprehensive Integration: Combines CPU, memory, Ethernet, SCSI, and serial I/O on a single board.
- VME System Control: Acts as a full VMEbus system controller with arbitration and interrupt management.
- Battery-Backed RAM: MK48T08 provides non-volatile storage for system configuration and real-time clock.
Application Scenarios
Widely used in telecommunications, industrial automation, and aerospace test equipment.
Performance Parameters
- Data Width: Supports 8, 16, and 32-bit data transfers on the VMEbus.
- LAN Performance: Intel 82596CA supports 10Base-T Ethernet with DMA capabilities.
Material Composition
Heavy-duty 6U VME PCB with gold-plated backplane connectors and industrial-grade semiconductors.
Structural Characteristics
Standard 6U Eurocard VME form factor with front panel I/O ports and status LEDs.
Working Principle
The MC680x0 processor boots from EPROM/Flash, initializes the MCchip and VMEchip2, and loads the operating system. It manages local I/O via the PCI/local bus and communicates with the VME backplane via the VMEchip2.
Installation Requirements
Insert into a 6U VME chassis. Ensure P1 and P2 connectors are fully seated and locked.
Usage Precautions
Follow strict lithium battery precautions for the MK48T08. Do not short-circuit, disassemble, or expose to excessive heat.
