Product Details:

MOTOROLA MVME162-431 belongs to MVME162FX series 6U VMEbus single board computer, equipped with MC68LC040 32MHz 32-bit processor, 8KB on-chip cache and MMU, without integrated hardware FPU. This variant is configured with 16MB parity DRAM, 512KB battery-backed SRAM, four EIA-232-D serial ports, onboard 10Mbps Ethernet transceiver and four IndustryPack expansion slots, it does not integrate SCSI controller. It integrates 2MB flash memory for firmware storage, battery-backed real-time clock, programmable tick timers and hardware watchdog circuit. The built-in MVME162Bug monitor supports serial console debugging, memory verification and network boot configuration. This legacy embedded board is end-of-life, available stock are refurbished replacement spares for vintage VME automation racks.

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 adopts 16MB large parity memory and four IndustryPack mezzanine slots, paired with multi-channel serial ports and Ethernet upload function. It is suitable for multi-sensor field collection systems that send acquired field data to upper control host through Ethernet. Users can install IndustryPack mezzanine modules to add analog and digital signal channels 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 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 distributed data acquisition racks and factory monitoring subsystems requiring large parity memory, serial connection and Ethernet transmission. Typical application scenarios include VME rack auxiliary CPU replacement, multi-channel sensor network maintenance and automation platform retrofit. Automation integrators select this Motorola MVME162-431 for its MC68LC040, 32MHz 16MB parity DRAM configuration, four EIA-232-D serial ports, Ethernet and four IndustryPack slots, no SCSI.
