Product Details:

MOTOROLA MVME162-403 belongs to MVME162FX 400 series 6U VMEbus single board computer, equipped with MC68040 32MHz 32-bit processor with integrated hardware FPU and 8KB on-chip cache. This variant is configured with 8MB parity DRAM, 512KB battery-backed SRAM, four EIA-232-D serial ports, onboard narrow SCSI controller and 10Mbps Ethernet transceiver, paired with four IndustryPack expansion slots. It integrates 2MB flash memory for firmware storage, battery-backed real-time clock, multi-channel programmable timers and hardware watchdog circuit. The built-in MVME162Bug monitor supports serial console debugging, memory verification, SCSI boot and network boot configuration. This legacy embedded board is end-of-life, available stock are refurbished replacement spares for vintage VME automation and test systems.

This SBC can act as VMEbus master or slave and supports A16/A24/A32 addressing and D8/D16/D32 data transfer with interrupt management. It carries four independent serial channels for connecting multiple serial instruments and field sensors, and SCSI interface supports local mass storage for process data archiving. Ethernet enables real-time data upload to upper host systems. Users can install up to four IndustryPack mezzanine modules to add analog, digital and special signal interfaces according to project requirements. Optimized multi-layer PCB routing suppresses electromagnetic noise interference from servo drives and heavy industrial cabinet environments. It maintains stable compatibility with VxWorks and other classic real-time operating systems.

It adopts standard 6U eurocard mechanical specification and draws +5V, ±12V power supply from the VME backplane. Front panel provides serial connectors and status LED indicators, and the P2 rear connector routes Ethernet, SCSI and mezzanine signals to transition boards. Hot swap operation is not supported; power supply must be shut down before installation or removal. The PCB and soldering assembly meet industrial shock and vibration specifications for cabinet mounting.

It is widely deployed in multi-channel data acquisition racks and semiconductor auxiliary control subsystems requiring abundant expansion resources. Typical application scenarios include VME rack main CPU replacement, multi-instrument serial network upgrade and high-channel-count test bench maintenance. Automation integrators select this Motorola MVME162-403 for its MC68040 FPU, 32MHz 8MB parity DRAM configuration, four EIA-232-D serial ports, SCSI, Ethernet and four IndustryPack slots.
