The Motorola MVME147-013 is a VMEbus single-board computer (SBC) featuring the MC68030 enhanced 32-bit microprocessor. It was among the first general-purpose microprocessors with on-chip instruction and data cache memory, significantly boosting processing performance by 20 to 40 percent over previous generations. Operating at clock speeds of 16, 25, or 33.33 MHz, the MVME147-013 supports various configurations including 16MB of shared DRAM with programmable parity for error checking, and up to 4MB of EPROM storage through multiple sockets.
This single-board computer integrates numerous peripheral controllers on board, eliminating the need for many additional backplane modules and saving crucial VMEbus slots for other functions. It includes four serial communication ports (EIA-232-D), a Centronics parallel printer port, and Ethernet networking through the AM7990 controller. The design also features two 16-bit timers, a watchdog timer for system health monitoring, and a SCSI bus interface with DMA capabilities, making it suitable for high-performance embedded computing tasks in industrial automation, telecommunications, or military applications.
