BU-61689 Datasheet, PDF (1/12 Pages) List of Unclassifed Manufacturers – MINIATURE ADVANCED COMMUNICATION ENGINE (MINI-ACE) AND MINI-ACE PLUS

BU-65178/65179*/61588/61688*/61689*
MINIATURE ADVANCED
COMMUNICATION ENGINE
(MINI-ACE) AND MINI-ACE PLUS*
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.
