DESCRIPTION
The PCI Enhanced Mini-ACE family of MIL-STD-1553 terminals provides a
complete interface between a 32-Bit / 33Mhz PCI Bus and a MIL-STD-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 PCI Enhanced Mini-ACE is nearly 100%
footprint and software compatible with the Enhanced Mini-ACE, previous
generation Mini-Ace (Plus) terminals, and is software compatible with the older
ACE series.
The PCI Enhanced Mini-ACE is powered by 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 1553 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 PCI Enhanced Mini-ACE RT offers the same choices of subaddress
buffering as the ACE, Mini-ACE (Plus) and Enhanced Mini-ACE, 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.
