DESCRIPTION
The Mini-ACE Mark3 is the world's first MIL-STD-1553 terminal pow-
ered entirely by 3.3 volts, thus eliminating the need for a 5 volt power
supply. With a package body of 0.88 inches square and a gull wing
"toe-to-toe" dimension of 1.13 inches max, the Mark3 is the industry's
smallest ceramic gull-lead 1553 terminal, enabling its use in applica-
tions where PC board space is at a premium.
The Mark3 integrates dual transceiver, protocol logic, and either 4K or
64K words of internal RAM. The Mark3's architecture is identical to
that of the Enhanced Mini-ACE, and most features are functionally
and software compatible with the previous Mini-ACE (Plus) and ACE
generations.
A salient feature of the Mark3 is its advanced bus controller architec-
ture. This provides methods to control message scheduling, the
means to minimize host overhead for asynchronous message inser-
tion, facilitate bulk data transfers and double buffering, and support
various message retry and bus switching strategies.
The Mark3's remote terminal architecture provides flexibility in meet-
ing all common MIL-STD-1553 protocols. The choice of RT data
buffering and interrupt options provides robust support for synchro-
nous and asynchronous messaging, while ensuring data sample
consistency and supporting bulk data transfers. The Mark3's monitor
mode provides true message monitoring, and supports filtering on an
RT address/T-R bit/subaddress basis.
The Mark3 incorporates fully autonomous built-in self-tests of its
internal protocol logic and RAM. The Mark3 terminals 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.
