2. Core Specifications

• Processor: Motorola MC68LC040, 25 MHz, without Floating Point Unit (FPU), with MMU and 8KB internal cache

• Main DRAM: 4 MB parity-checked DRAM

• Battery-Backed SRAM: 512 KB

• Flash Memory: 1 MB (for firmware/boot monitor storage)

• NVRAM & RTC: 8 KB NVRAM integrated with Real-Time Clock, battery backup supported

• VMEbus Interface: Compliant with VMEbus standard, supports A32/D32, system controller capability

3. Onboard Interfaces

• SCSI-2 Interface: Onboard narrow SCSI-2 port for connecting SCSI hard disk, optical drive and storage devices

• Serial Ports:

  • 1 × Console serial port (EIA-232-D)

  • 1 × Configurable serial port (EIA-232/422 selectable)

• Front Panel: LED status indicators, reset switch, abort switch

• Others: No onboard Ethernet, no IndustryPack (IP) module slots

4. Mechanical & Environmental

• Form Factor: 6U VMEbus single slot board

• Operating Temperature: 0°C ~ +55°C (standard industrial grade)

• Storage Temperature: -40°C ~ +85°C

• Humidity: 5% ~ 95% non-condensing

5. Firmware & Software Support

• Boot Monitor: 162BUG firmware (Motorola proprietary monitor)

• Supported OS: VxWorks, LynxOS, other real-time operating systems, traditional Unix-like embedded systems

• Functions: System boot, hardware self-test, memory configuration, VMEbus resource mapping, serial console debugging

6. Model Difference (MVME162 Series)

• MVME162-011A: SCSI-2 + 512KB battery SRAM, no Ethernet, no IP slots

• MVME162-010A: IP slots + dual serial ports, no SCSI

• MVME162-012A: IP slots + Ethernet, no SCSI

• MVME162-013A: SCSI + Ethernet, no IP slots

7. Typical Applications

• Industrial automation DCS and large machinery control systems

• VMEbus-based automatic test equipment

• Military, aerospace and transportation embedded control

• Legacy industrial equipment spare part replacement

8. Maintenance Notes

• Onboard backup battery needs periodic replacement to avoid RTC/NVRAM data loss

• Support VMEbus master/slave mode configuration via onboard jumpers

• Before power-on, check jumper setting, SCSI terminal resistance and serial port wiring
