Description

Motorola MVME162PA-252SE

Technical Specifications

  • Microprocessor: 25 MHz MC68040 enhanced 32-bit microprocessor with integrated 8KB cache, Memory Management Unit (MMU), and Floating-Point Unit (FPU).
  • Main Memory: 16MB Synchronous Dynamic Random Access Memory (SDRAM) with hardware ECC protection.
  • Storage Resources: 512KB battery-backed SRAM, 1MB Flash memory, and 8K x 8 NVRAM with battery-backed Time-of-Day (TOD) clock.
  • Bus Interface: A32/D64 VMEbus master/slave interface with full system controller functionality.

Functional Features

  • Second-Generation Petra ASIC: Integrates memory management, VME interface, and timing functions into a single chip, significantly enhancing memory subsystem performance and reducing latency.
  • High-Performance DMA: Supports Direct Memory Access for VMEbus D64 block transfers and local bus memory burst cycles, offloading data transfers from the CPU.
  • Integrated Network & Storage: Features onboard 10/100Mbps Ethernet and SCSI interfaces, both utilizing DMA for high-speed throughput.
  • Serial Communications: Provides four asynchronous serial ports (EIA-232-D DTE) routed to RJ45 connectors.
  • IndustryPack Expansion: Accommodates up to two IndustryPack (IP) modules via a 32-bit data path, with dedicated DMA channels for each IP slot.
  • System Timers: Includes six 32-bit tick timers and a hardware watchdog timer to prevent system lockups.

Application Scenarios
Extensively utilized in semiconductor manufacturing tools, advanced motion control systems, radar signal processing, aerospace ground systems, automated test equipment (ATE), and distributed industrial control systems.

Performance Parameters

  • Power Requirements: +5Vdc (±5%) at 3.5A typical and 4.5A maximum; +12Vdc and -12Vdc at 100mA maximum each.
  • Thermal Specifications: Operating temperature ranges from 0°C to 70°C exit air with forced-air cooling. Storage temperature ranges from -40°C to +85°C.
  • Environmental Tolerance: Operates reliably in 5% to 90% relative humidity (non-condensing).
  • Interrupt Handling: Supports a 7-level VMEbus interrupter and interrupt handler for real-time event processing.

Material Composition
Constructed using high-Tg, multi-layer industrial-grade printed circuit boards (PCBs). Populated with commercial or industrial-grade integrated circuits, including the MC68040 processor, SDRAM modules, and the custom Petra ASIC. Critical components are often coated with conformal coating to protect against moisture, dust, and chemical exposure.

Structural Characteristics

  • Form Factor: Standard 6U Double-High VME module.
  • Dimensions: PC board height is 9.187 inches (233.35 mm), depth is 6.299 inches (160.00 mm), and thickness is 0.662 inch (16.77 mm). With connectors and front panel, height is 10.309 inches (261.85 mm), depth is 7.4 inches (188 mm), and thickness is 0.80 inch (20.32 mm).
  • Front Panel I/O: Features four RJ45 serial port connectors, status LEDs (RUN, FAIL, STAT, SCON, LAN, FUSE, SCSI, VME), and two pushbutton switches (RESET and ABORT).
  • Backplane Connectors: Utilizes standard 6U VME P1 and P2 connectors for power, data, and address lines.
