Product Details:

MOTOROLA MVME162-520A belongs to MVME162FX 500 series 6U VMEbus single board computer, equipped with MC68040 33MHz 32-bit processor with integrated hardware FPU and 8KB on-chip cache and MMU. This variant is configured with 8MB parity DRAM, 512KB battery-backed SRAM, dual configurable EIA-232-D/EIA-530 serial ports and four IndustryPack expansion slots, it does not integrate SCSI controller and Ethernet transceiver. 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 and boot parameter setup. 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 carries MC68040 floating-point processor for motion control and complex numerical calculation tasks. It provides configurable serial communication ports for connecting serial field instruments and sensors. Users can install up to four IndustryPack mezzanine modules to add analog, digital and special signal interfaces to build multi-channel acquisition systems 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 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 legacy motion control subsystems and laboratory multi-channel test systems requiring floating-point operation and abundant IndustryPack expansion resources, without SCSI storage and Ethernet demands. Typical application scenarios include VME rack main CPU replacement, multi-sensor analog acquisition system maintenance and automation platform retrofit. Automation integrators select this Motorola MVME162-520A for its MC68040 FPU, 33MHz 8MB parity DRAM configuration, configurable serial ports and four IndustryPack slots, no SCSI and Ethernet.
