BU-65170/61580 and BU-61585 MIL-STD-1553A/B NOTICE 2 RT and BC/RT/MT, ADVANCED COMMUNICATION ENGINE (ACE) ACE User’s Guide Also Available DESCRIPTION DDC's BU-65170, BU-61580 and BU-61585 Bus Controller / Remote Terminal / Monitor Terminal (BC/RT/MT) A d v a n c e d Communication Engine (ACE) terminals comprise a complete integrated interface between a host processor and a MIL-STD-1553 A and B or STANAG 3838 bus. The ACE series is packaged in a 1.9 square-inch, 70-pin, low-profile, cofired MultiChip Module (MCM) ceramic package that is well suited for applications with stringent height requirements. The BU-61585 ACE integrates dual transceiver, protocol, memory management, processor interface logic, and a total of 12K words of RAM in a choice of DIP or flat pack packages. The BU-61585 requires +5 V power and either -15 V or -12 V power. The BU-61585 internal RAM can be configured as 12K x 16 or 8K x 17. The 8K x 17 RAM feature provides capability for memory integrity checking by implementing RAM parity generation and verification on all accesses. To minimize board space and “glue” logic, the ACE provides ultimate flexibility in interfacing to a host processor and internal/external RAM. The advanced functional architecture of the ACE terminals provides software compatibility to DDC's Advanced Integrated Multiplexer (AIM) series hybrids, while incorporating a multiplicity of architectural enhancements. It allows flexible operation while off-loading the host processor, ensuring ...
