DESCRIPTION

The BU-61588 Mini-ACE and BU-61688 Mini-ACE Plus* integrates two

5-volt-only transceivers, protocol, memory management, processor interface

logic, and 4K x 16, or 64K x 16* words of RAM in a choice of pin grid array

(PGA), quad flat pack or gull lead packages. The Mini-ACE is packaged in a

1.0 square inch, low profile, cofired ceramic multi-chip-module (MCM) pack-

age making it the smallest integrated MIL-STD-1553 BC/RT/MT in the indus-

try.

The Mini-ACE provides full compatibility to DDC’s BU-61580 and BU-65170

Advanced Communication Engine (ACE). As such, the Mini-ACE includes all

the hardware and software architectural features of the ACE.

The Mini-ACE contains internal address latches and bidirectional data buffers

to provide a direct interface to a host processor bus. The memory manage-

ment scheme for RT mode provides three data structures for buffering data.

These structures, combined with the Mini-ACE’s extensive interrupt capabili-

ty, serve to ensure data consistency while off-loading the host processor.

The Mini-ACE Plus* can optionally boot-up as a RT with the Busy bit set for

1760 applications. The Mini-ACE BC mode implements several features

aimed at providing an efficient real-time software interface to the host proces-

sor including automatic retries, programmable intermessage gap times, auto-

matic frame repetition, and flexible interrupt generation.

The advanced architectural features of the Mini-ACE, combined with its small size

and high reliability, make it an ideal choice for demanding military and industrial

processor-to-1553 applications.
