BU-61580 Datasheet | DDC

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 munication Engine (ACE) terminals prise a plete 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 Multi Chip 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 patibility 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 data sample consistency, and supports bulk data transfers. The ACE hybrids may be operated at either 12 or 16 MHz. Wire bond options allow for programmable RT address (hardwired is standard) and external transmitter inhibit inputs. http://..net/ FEATURES - Fully Integrated MIL-STD-1553 Interface Terminal Interface - Flexible Processor/Memory - Standard 4K x 16 RAM and - Optional RAM Parity Optional 12K x 16 or 8K x 17 RAM Available Generation/Checking - Automatic BC Retries - Programmable BC Gap Times - BC Frame Auto-Repeat - Flexible RT Data Buffering - Programmable Illegalization - Selective Message Monitor - Simultaneous RT/Monitor...
