Product Details:

MOTOROLA MVME148 belongs to MVME68k series 6U VMEbus single board computer, upgraded platform after MVME147 series, equipped with MC68040 32-bit integrated processor with built-in floating-point unit. It supports configurable onboard DRAM, integrated Ethernet controller, multiple EIA-232-D serial ports, parallel printer port and SCSI interface. It carries battery-backed CMOS RAM, real-time clock, watchdog timer and VME system arbitration logic, supports VMEbus A32/D32 master and slave mode. This legacy SBC is discontinued, available stock are refurbished spare units for semiconductor manufacturing equipment, industrial test racks and vintage VME control systems.

This CPU board works as the main computing master inside standard VME chassis. It executes real-time control programs, collects signals from VME I/O modules and communicates with host system. The onboard VMEbug monitor firmware supports serial debugging, memory access and boot configuration. Shielded backplane wiring reduces electromagnetic interference generated by servo power units and harsh workshop environment. It supports VxWorks and other mature 68k real-time operating systems.

It adopts standard 6U double eurocard form factor, powered by +5V, ±12V DC supplied from VME backplane. Front panel carries SCON, RUN, FAIL, STATUS LED indicators, plus RESET and ABORT push buttons for convenient on-site diagnosis. P2 rear connector expands SCSI and extended peripheral signals. Hot swap is not supported, power must be cut off before removal and replacement. Industrial PCB and anti-vibration soldering process adapt to continuous factory multi-shift operation.

All units pass power-on self-test, memory inspection, VME bus handshake test, Ethernet, serial and SCSI communication test and long-time aging test before shipment to guarantee stable real-time operation under industrial production.

It is widely used on semiconductor processing equipment, metallurgy data acquisition cabinets, industrial measurement platforms and old CNC control systems. Typical application scenarios include VME rack main CPU replacement, legacy automation system maintenance and equipment retrofit. Automation integrators select this Motorola MVME148 for its MC68040 integrated FPU architecture and upgraded performance compared with MVME147 series.
