BU-6186X

The Enhanced Miniature Advanced Communications Engine (Enhanced Mini-ACE) and -ACE (Micro-ACE) family of MIL-STD-1553 terminals provide complete interfaces between a host processor and a 1553 bus, and integrate dual transceiver, protocol logic, and 4K or 64K words of RAM.At 0.815" square, the -ACE (BGA package) option provides the smallest footprint in the industry.

The terminals are powered by a choice of 5V or 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 message sequence control engine, with a set of 20 instructions.

This feature 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/-ACE incorporates a fully autonomous built-in self-test, providing 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.

The 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. Most software features are compatible with the previous generations of the Mini-ACE (Plus) and ACE series.
