DESCRIPTION

The Enhanced Miniature Advanced Communications Engine

(Enhanced Mini-ACE) family of MIL-STD-1553 terminals provide com-

plete interfaces between a host processor and a 1553 bus, and integrate

dual transceiver, protocol logic, and 4K words or 64K words of RAM.

These terminals are nearly 100% footprint and software compatible

with the previous generation Mini-ACE (Plus) terminals, and are soft-

ware compatible with the older ACE series.

They are powered by a choice of 5V or 3.3V logic. Multiprotocol sup-

port 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 message sequence control engine, with

a set of 20 instructions. This provides an autonomous means of

implementing multi-frame message 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 comprehensive

testing of the internal protocol logic and/or RAM.

The RT offers the same choices of subaddress buffering as the ACE

and Mini-ACE (Plus), along with a global circular buffering option,

50% rollover interrupt for circular buffers, an interrupt status queue,

and an "Auto-boot" option to support MIL-STD-1760.

These terminals provide the same flexibility in host interface configu-

rations as the ACE/Mini-ACE, along with a reduction in the host

processor's worst case holdoff time.
