Product Details:

MOTOROLA MVME162-003 belongs to MVME162 series 6U VMEbus single board computer, equipped with MC68LC040 25MHz 32-bit processor without built-in FPU. This variant is configured with 1MB DRAM, 512KB battery-backed SRAM and two EIA-232-D serial ports, it does not integrate VMEbus interface, SCSI controller and Ethernet transceiver. It integrates battery-backed NVRAM, real-time clock and watchdog timer function. The onboard VME162Bug monitor firmware supports serial debug, memory operation and system boot configuration. This legacy SBC is discontinued, available stock are refurbished spare units for standalone embedded control, industrial test racks and vintage automation systems.

This CPU board works as local computing controller without VME bus connection, it executes standalone real-time control programs and communicates with peripheral devices via serial ports. Shielded wiring reduces electromagnetic interference generated by servo power units and harsh workshop environment. It has good compatibility with classic real-time operating systems such as VxWorks and RTEMS.

It follows standard 6U double eurocard form factor, powered by +5V, ±12V DC supplied from backplane. Front panel carries STATUS LED indicators, plus RESET push button for convenient on-site diagnosis. P2 rear connector expands serial and IndustryPack I/O signals. Hot swap is not supported, power supply must be cut off before removal and replacement. Industrial PCB and vibration-resistant soldering process adapt to continuous factory multi-shift operation.

All units pass power-on self-test, memory detection, serial communication test and long-time aging test before shipment to guarantee stable real-time operation.

It is widely used on industrial test equipment, simple data acquisition cabinets and old standalone CNC control systems. Typical application scenarios include standalone embedded controller replacement, legacy automation system maintenance and equipment retrofit. Automation integrators select this Motorola MVME162-003 for its 25MHz 1MB DRAM configuration and no VMEbus design.
