Product Details:

MOTOROLA MVME147SA-1 belongs to MVME147S series 6U VMEbus single board computer, it is the special SA hardware variant of MVME147 platform. Equipped with MC68030 25MHz 32-bit processor and MC68888 floating-point coprocessor, configured with 8MB parity DRAM, onboard Ethernet transceiver, four EIA-232-D serial ports, one Centronics parallel printer port and DMA SCSI interface. It integrates 2K×8 battery-backed SRAM, real-time clock, watchdog timer and VME system controller function. This legacy SBC is discontinued, available stock are refurbished spare units for legacy VME control racks, semiconductor manufacturing equipment and vintage CNC systems.

This CPU board acts as the main master controller inside VME chassis. It supports A32/D32, A24/D16 VMEbus protocol, works as bus master or slave and processes 7-level VME interrupts. The onboard VMEbug firmware supports serial debugging, memory operation and system boot configuration. Shielded backplane wiring reduces electromagnetic interference generated by servo power units and harsh workshop environment. It is widely compatible with classic real-time operating systems such as VxWorks.

It adopts standard 6U double eurocard form factor, powered by +5V, ±12V from VME backplane. Front panel is equipped with SCON, RUN, FAIL, STATUS LED indicators, plus RESET and ABORT push buttons for on-site diagnosis. P2 rear connector expands SCSI and extra peripheral 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 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 multi-shift industrial production.

It is widely used on semiconductor manufacturing 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 MVME147SA-1 for its special SA revision, 25MHz 8MB parity configuration and built-in Ethernet plus SCSI peripheral resources.
