Product Details:

MOTOROLA 01-W3781B03C is the PCB revision part number of MVME147S-1, belongs to MVME147 series 6U double-high VMEbus embedded single board computer, equipped with MC68030 25MHz 32-bit processor paired with MC68882 floating-point coprocessor. This variant is configured with 4MB parity DRAM, 512KB EPROM for firmware storage, 8KB battery-backed NVRAM integrated with real-time clock, two EIA-232-D serial ports, AUI 10Mbps Ethernet interface and SCSI storage controller, also equipped with Centronics compatible parallel printer port. It supports VMEbus A16/A24/A32 addressing and D8/D16/D32 BLT DMA transfer, can act as VME system controller, integrates programmable timers and hardware watchdog circuit. The built-in debug monitor supports serial console debugging, self-test diagnostics and network boot configuration. This legacy embedded board is end-of-life, available stock are refurbished replacement spares for vintage industrial and test automation systems.

This SBC can act as VMEbus master or slave and provides reliable 32-bit data transmission on the VME backplane. The MC68030+MC68882 combination delivers floating-point computing capability for real-time control and data acquisition tasks. It provides dual serial channels for console setup and peripheral communication, SCSI interface for legacy storage connection and AUI Ethernet port for host communication. Users can match it with other VMEbus I/O and acquisition modules to build stable embedded control systems. Optimized PCB layout suppresses electromagnetic interference, and it maintains stable compatibility with VxWorks, OS-9 and other classic real-time operating systems for MC68K platform.

It adopts standard double-high 6U eurocard mechanical specification and draws +5V, ±12V power supply from the VME backplane. Front panel provides serial connectors, AUI Ethernet port, SCSI port, parallel port and status LED indicators. 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 semiconductor test equipment, industrial control subsystems and long-cycle industrial data logging racks requiring MC68030 floating-point operation, parity memory protection, 25MHz CPU, SCSI storage, Ethernet communication and parallel port expansion capability. Typical application scenarios include VME rack main CPU replacement, low-cost multi-task data acquisition system maintenance and legacy automation platform retrofit. Automation integrators select this Motorola 01-W3781B03C for its MC68030 25MHz,4MB parity DRAM configuration, serial ports,SCSI,Ethernet,parallel port.
