Description

Motorola MVME162PA-252FP

Technical Specifications

  • Microprocessor: 25 MHz MC68040 enhanced 32-bit microprocessor (includes 8KB cache, MMU, and FPU).
  • Main Memory: 16MB SDRAM with parity protection.
  • Non-Volatile Storage: 512KB battery-backed SRAM, 1MB Flash memory, and 8K x 8 NVRAM with a battery-backed real-time clock.
  • Bus Interface: A32/D64 VMEbus master/slave interface with full system controller functionality.

Functional Features

  • Floating-Point Unit: Integrated FPU enables complex mathematical computations and advanced motion control algorithms.
  • Petra ASIC Integration: Optimizes local bus memory burst cycles and VMEbus D64 block transfers.
  • IndustryPack Expansion: Supports up to four 16-bit or two 32-bit IndustryPack (IP) ports.
  • Serial Communications: Features two serial ports (one EIA-232-D DCE console port and one user-configurable EIA-232-D/EIA-422 port).

Application Scenarios
Ideal for advanced motion control, radar signal processing, precision instrumentation, and applications requiring heavy floating-point math.

Performance Parameters

  • Timers: Includes six 32-bit programmable tick timers and one hardware watchdog timer.
  • Power Requirements: +5Vdc (±5%) at 3.5A typical, 4.5A max; +12Vdc and -12Vdc at 100mA max.
  • Thermal Specifications: Operating temperature 0°C to 70°C exit air with forced-air cooling; storage temperature -40°C to +85°C.

Material Composition
Constructed using high-Tg, multi-layer industrial-grade PCBs with conformal coating, populated with high-reliability MC68040 processors, SDRAM modules, and the custom Petra ASIC.

Structural Characteristics
Standard 6U Double-High VME module. Features standard VME P1/P2 backplane connectors, front-panel status LEDs, and physical ABORT/RESET pushbutton switches.

Working Principle
The MC68040 processor manages the local bus and communicates with the Petra ASIC. The ASIC handles memory management, VMEbus arbitration, and DMA transfers, while the FPU handles complex math operations in parallel with the CPU’s integer operations.

Installation Requirements

  • Must be inserted into a compatible 6U VME card cage slot and secured with front-panel screws.
  • Hardware switches on the board must be configured to match the installed SDRAM capacity and boot behavior.
  • Forced-air cooling is mandatory to maintain the exit air temperature below 70°C.
