ENHANCED MINIATURE ADVANCED

COMMUNICATIONS ENGINE

[ENHANCED MINI-ACE/µ-ACE (MICRO-ACE)]

FEATURES

• Fully Integrated 1553A/B Notice 2,

McAir, STANAG 3838 Interface Terminal

• Compatible with Mini-ACE (Plus)

and ACE Generations

• Choice of :

RT or BC/RT/MT In Same Footprint

- RT or BC/RT/MT with 4K RAM

- BC/RT/MT with 64K RAM, and RAM

parity

• Choice of 5V or 3.3V Logic

• Package Options:

- 1" Square Ceramic Flat Pack or

Gull Wing

- 0.815" Square BGA (µ-ACE)

DESCRIPTION

• 5V Transceiver with 1760 and McAir

Compatible Options

The Enhanced Miniature Advanced Communications Engine (Enhanced

Mini-ACE) and µ-ACE (Micro-ACE) family of MIL-STD-1553 terminals pro-

vide complete interfaces between a host processor and a 1553 bus, and

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

• Comprehensive Built-In Self-Test

• Flexible Processor/Memory Interface,

with Reduced Host Wait Time

At 0.815" square, the µ-ACE (BGA package) option provides the

smallest footprint in the industry.

• Choice of 10, 12, 16, or 20 MHz Clock

• Highly Autonomous BC with

Built-In Message Sequence Control:

- Frame Scheduling

The terminals are powered by a choice of 5V or 3.3V logic.

Multiprotocol support of MIL-STD-1553A/B and STANAG 3838, includ-

ing versions incorporating McAir compatible transmitters, is provided.

There is a choice of 10, 12, 16, or 20 MHz clocks. The BC/RT/MT ver-

sions with 64K words of RAM include built-in RAM parity checking.

- Branching

- Asynchronous Message Insertion

- General Purpose Queue

- User-defined Interrupts

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/µ-ACE incor-

porates a fully autonomous built-in self-test, providing comprehensive

testing of the internal protocol logic and/or RAM.

• Advanced RT Functions

- Global Circular Buffering

- Interrupt Status Queue

- 50% Circular Buffer Rollover

Interrupts

• Selective Message Monitor

- Selection by Address, T/R Bit,

Subaddress

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.

- Command and Data Stacks

- 50% and 100% Stack Rollover

Interrupts

The terminals provide the same flexibility in host interface configura-

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

sor's worst case holdoff time. Most software features are compatible

with the previous generations of the Mini-ACE (Plus) and ACE series.
