The Curtiss-Wright/Synergy Microsystems V452-B is a VMEbus Single Board Computer engineered for embedded applications requiring high-performance 68K processing. This single-board solution supports Motorola 68040 or 68060 processors at speeds up to 33 MHz (68040) or 66 MHz (68060), paired with configurable memory up to 128 MB DRAM and 16 MB Flash. The V452-B integrates 10Base-T Ethernet and an EZ-Bus mezzanine interface for high-bandwidth expansion, enabling integration of specialized I/O and peripheral modules. The board delivers approximately 50% power reduction versus comparable 68K platforms and accommodates ruggedization, EMI filtering, and conformal coating for harsh operational environments.
