Description

MOTOROLA MVME215-1 is a single-height VME memory and I/O carrier board, designed to expand memory capacity and I/O connectivity for MVME162-series single-board controllers (SBCs) in industrial automation and embedded real-time systems. MOTOROLA MVME215-1 integrates 8MB DRAM (expandable to 32MB), 512KB battery-backed SRAM, and dual IndustryPack (IP) slots, enabling seamless I/O expansion for analog/digital control and communication modules. MOTOROLA MVME215-1 supports A32/D32 VMEbus slave operation, with a VMEbus interface that auto-configures to match the host SBC, ensuring plug-and-play integration with MOTOROLA MVME162-014 and MOTOROLA MVME162-262. Its battery-backed SRAM preserves critical process data during power outages, while its industrial-grade design withstands harsh factory and utility environments. Whether adding memory to legacy VME systems or expanding I/O for custom control loops, MOTOROLA MVME215-1 delivers reliable performance and backward compatibility.

Advantages and Features MOTOROLA MVME215-1

  1. VMEbus Compatibility: MOTOROLA MVME215-1 auto-configures to A32/D32 VMEbus slave mode, ensuring seamless integration with MVME162-series SBCs and legacy VME backplanes.
  2. Memory Scalability: 8MB base DRAM (expandable to 32MB) supports larger application code and data sets for complex control loops.
  3. I/O Expansion: Dual IndustryPack slots allow flexible addition of motion control, I/O, or communication modules, ideal for custom automation setups.
  4. Data Retention: Battery-backed SRAM and TOD clock preserve critical process data during power outages, minimizing downtime and data loss.
  5. Compact Design: Single-height form factor saves VMEbus backplane space, enabling more modules in a single chassis.

Application Cases

  1. Power Plant DCS Memory Upgrade: A 600MW gas-fired plant added MOTOROLA MVME215-1 to its MOTOROLA MVME162-262-based DCS. The upgrade expanded memory to 32MB, supporting larger control algorithms and reducing data bottlenecks by 40%.
  2. Semiconductor Wafer Test Equipment: A fab used MOTOROLA MVME215-1 to add two IP-based analog I/O modules to its MOTOROLA MVME162-014 SBC. The expansion enabled precise voltage/current monitoring, boosting test yield by 12%.
  3. Oil Refinery Compressor Control: A refinery deployed MOTOROLA MVME215-1 to expand I/O for a MOTOROLA MVME162-262-based anti-surge system. Dual IP slots added vibration sensors and valve control modules, cutting unplanned shutdowns by 18%.

Selection Suggestions

  1. Choose MOTOROLA MVME215-1 for MVME162-series SBC upgrades needing 8MB–32MB memory expansion and dual IP slots.
  2. Opt for MOTOROLA MVME215-1 in applications requiring battery-backed data retention and seamless VMEbus slave integration.
  3. Select MOTOROLA MVME215-1 if you need a cost-effective, compact solution to add memory and I/O to legacy VME systems.
  4. Use MOTOROLA MVME215-1 to expand I/O for custom control loops while preserving existing VME backplanes and SBCs.

Precautions

  1. Ensure VMEbus backplane compatibility (A32/D32) to enable full slave mode operation of MOTOROLA MVME215-1.
  2. Replace SRAM backup battery every 2–3 years to avoid data loss during power cycles.
  3. Use a regulated +5V/±12V power supply (5A max for +5V) to prevent voltage spikes from damaging memory and IP slot connectors.
  4. Follow ESD protocols when handling MOTOROLA MVME215-1 to protect sensitive ICs and VMEbus interface.
  5. Verify IndustryPack module compatibility (16/32-bit, DMA-capable) for optimal performance in the two IP slots.
