Description

Motorola MVME1603-053

Technical Specifications

  • Microprocessor: PowerPC 603 RISC microprocessor.
  • Base Board Architecture: MVME1600-011, optimized for enhanced I/O handling and system control.
  • VMEbus Interface: Supports A24/A32 addressing and D8/D16/D32/D64 block transfers.
  • Memory: Onboard shared DRAM with a software-selectable base address, plus optional 256KB L2 cache memory.
  • Graphics: Super VGA high-resolution color graphics utilizing the CL-GD5434 graphics accelerator.
  • Storage Interfaces: Integrated floppy disk controller via PC87303 SIO and SCSI support.

Functional Features

  • VME System Controller: Functions as a VMEbus system controller, managing bus arbitration and interrupt handling.
  • PCI/PMC Expansion: Features a PCI bus supporting the IEEE P1386.1 PMC (PCI Mezzanine Card) standard for versatile I/O expansion (e.g., FDDI, ATM, Ethernet).
  • Dual-Bus Bridging: Acts as both a VMEbus-to-local-bus and local-bus-to-VMEbus interface.
  • Direct Memory Access: High-speed DMA for fast local memory to VMEbus transfers.
  • Interprocessor Communication: Includes a Global Control and Status Register (CSR) for multi-processor communication.

Application Scenarios
Ideal for complex multiprocessor systems, advanced laboratory test equipment, industrial automation, and OEM systems requiring high-speed graphics and flexible PMC expansion.

Performance Parameters

  • Power Draw: Sourced directly from the VMEbus backplane P1 and P2 connectors.
  • Data Path: Native 32-bit address and 32-bit data (A32/D32) operation, with software handling for D8/D16 devices.
  • Interrupt Handling: Integrated VMEbus interrupter and interrupt handler.

Material Composition
Constructed with multi-layer industrial-grade PCBs, populated with the PowerPC 603 processor, CL-GD5434 graphics accelerator, PC87303 Super I/O chip, and high-density DRAM modules.

Structural Characteristics

  • Form Factor: Standard 6U Double-High VME module.
  • Connectors: Standard VME P1 and P2 backplane connectors.
  • I/O Routing: Front panel I/O for PMC modules and optional keyboard/mouse/graphics support specific to the MVME1600-011 base board.

Working Principle
The PowerPC 603 processor executes instructions on the local bus. The MVME1600-011 base board bridges the local bus to the VME backplane, translating protocols and managing DMA transfers. The PCI bus routes signals to the PMC slot, allowing modular expansion without altering the base board logic.
