DESCRIPTION
The Enhanced Mini-ACE family of
MIL-STD-1553 terminals provide
complete interfaces between a
host processor and a 1553 bus.
These terminals integrate dual
transceiver, protocol logic, and
4K words or 64K words of RAM.
With a 1.0 inch square package,
the Enhanced Mini-ACE is nearly
100% footprint and software com-
patibile with the previous genera-
tion Mini-ACE (Plus) terminals,
and is software compatibile with
the older ACE series.
The Enhanced Mini-ACE is pow-
ered by a choice 5V, or 5V/3.3V
(3.3V logic). Multiprotocol support
of
MIL-STD-1553A/B
and
STANAG 3838, including versions
incorporating McAir compatible
transmitters, is provided. There is a
choice of 10, 12, 16, or 20 Mhz
clocks. The BC/RT/MT versions
with 64K words of RAM include
built-in RAM parity checking.
BC features include a built-in mes-
sage sequence control engine,
with a set of 20 instructions. This
provides an autonomous means of
implementing multi-frame mes-
sage scheduling, message retry
schemes, data double buffering,
asynchronous message insertion,
and reporting to the host CPU. The
Enhanced Mini-ACE incorporates
a fully autonomous built-in self-
test, which provides comprehen-
sive testing of the internal protocol
logic and/or RAM.
The Enhanced Mini-ACE RT offers
the same choices of subaddress
buffering as the ACE and Mini-
ACE (Plus), along with a global cir-
cular buffering option, 50% rollover
interrupt for circular buffers, an
interrupt status queue, and an
"Auto-boot" option to support MIL-
STD-1760.
The Enhanced Mini-ACE termi-
nals provide the same flexibility in
host interface configurations as
the ACE/Mini-ACE, along with a
reduction in the host processor's
worst case holdoff time.
