Description

Motorola MVME162P-242SE

Technical Specifications

  • Microprocessor: 25 MHz MC68040 enhanced 32-bit microprocessor, featuring an 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 for maximum data integrity.
  • Non-Volatile Storage: 1MB Flash memory for onboard monitor/debugger firmware or user-installed code.
  • Battery-Backed Memory: 512KB SRAM and 8K x 8 NVRAM with battery backup for program, data, and Time-of-Day clock retention.
  • VMEbus Interface: A32/D64 VMEbus master/slave interface with full system controller functionality.

Functional Features

  • Second-Generation Petra ASIC: Integrates the functions of previous MC2, IP2, and MCECC chips into a single ASIC, 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, supporting baud rates from 110b/s to 38.4Kb/s.
  • IndustryPack Expansion: Accommodates up to two IndustryPack (IP) modules (or four single-width 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
This controller is 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 requiring high computational power and fault-tolerant memory.

Performance Parameters

  • Power Requirements: Draws power directly from the VMEbus backplane via P1 and P2 connectors. Requires +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
The board is constructed using high-Tg, multi-layer industrial-grade printed circuit boards (PCBs). It is 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.
