DY-4 SVME-163-144 Single Board Computer w/ MAX-220 SCSI/Ethernet Board

The Curtiss-Wright / DY-4 SVME/DMV-163 Single Board Computer, (SBC), built with state-of-the-art technology, combines a high-performance 33 MHz 68040 processor and up to 64M bytes of DRAM on one circuit card. The card is equipped with DY 4's MAXPack interface, a standard mezzanine module approach to achieve additional expansion capability. System designers can increase the SBC's functionality by incorporating one of several standard MAXPack modules, or by developing their own custom module. MAXPack modules provide a single-slot solution for customers whose systems require specialized I/O. Traditionally, using multiple boards has been the only way to fulfill such system requirements.

The SVME/DMV-163's design features address mission-critical demands of military and aerospace systems integrators with increased computing performance, self-test coverage and functional density.

The card supports DY 4 Systems' standard features including an AVICS-based VMEbus interface, Built-In-Test (BIT), Bus Isolation mode (BI-mode), location monitor, and Auto-ID. These features bring benefits in performance, logistics and maintenance.

DY 4's custom-designed SCV64 chip implements all VMEbus interface functions with software-programmable features. It combines low-latency access to the VMEbus with high sustained throughputs. BIT hardware features verify all operational circuits on the module. BI-mode increases ease of testing and system fault location. The location monitor supports efficient inter-processor messaging, to minimize overhead in real-time software. Auto-ID allows boards to be self-configuring, based on slot location.
