DESCRIPTION
DDC’s BU-61582 Space Advanced Communication Engine (SP’ACE) is a radiation hardened version of the BU-61580 ACE terminal. DDC supplies the BU-61582 with enhanced screening for space and other high reliability applications. The BU-61582 provides a complete integrated BC/RT/MT interface between a host processor and a MIL-STD-1553 bus. The BU-61582 maintains functional and software compatibility with the standard BU61580 product and is packaged in the same 1.9 square-inch package footprint.

As an option, DDC can supply the BU-61582 with space level screening. This entails enhancements in the areas of element evaluation and screening procedures for active and passive elements, as well as the manufacturing and screening processes used in producing the terminals. The BU-61582 integrates dual transceiver, protocol, memory management and processor interface logic, and 16K words of RAM in the choice of 70-pin DIP or flat pack packages. Transceiverless versions may be used with an external electrical or fiber optic transceiver. To minimize board space and ‘glue’ logic, the SP’ACE terminals provide ultimate flexibility in interfacing to a host processor and internal/external RAM.
