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 pack-
aged in a 1.0 square inch, low profile,
cofired
ceramic
multi-chip-module
(MCM) package making it the smallest
integrated MIL-STD-1553 BC/RT/MT
in the industry.
The Mini-ACE provides full compatibil-
ity to DDC’s BU-61580 and BU-65170
Advanced
Communication
Engine
(ACE). As such, the Mini-ACE includes
all the hardware and software archi-
tectural 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 management scheme for
RT mode provides three data struc-
tures for buffering data. These struc-
tures, combined with the Mini-ACE’s
extensive interrupt capability, 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 processor including automatic
retries, programmable intermessage
gap times, automatic 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 indus-
trial processor-to-1553 applications.
