Military databus shrinks into BGA
A new option offers the smallest footprint of any MIL-STD-1553 integrated terminal in the industry and is the first of its kind offered in a BGA package.
Data Device Corporation (DDC) has expanded its Enhanced Mini-ACE MIL-STD-1553 component offering with the introduction of a ball grid array (BGA) package referred to as the Micro-ACE (u-ACE) This new package has the smallest footprint of any 1553 integrated terminal in the industry and is the first of its kind offered in a BGA package

Programmable option for avionics interfacing
DDC's new DD-42916I3 PCI mezzanine card analyses and simulates ARINC 429 data to and from electronic equipment and systems in commercial airlines and military avionics.
MIL-STD-1553 is the standard two-wire databus system used by the majority of the Western world's military aircraft as well as defence and space equipment.
"When you're designing components for military and avionics systems, keeping it small has many advantages", noted Todd Decker, Data Bus Marketing Manager at DDC.
"Designers have only so many square inches to work with and going from a one-inch-square gull lead package to a 0.8-inch-square BGA requires 35% less real estate on the card, opening up possibilities for multiple 1553 channels and other high density applications.

Military databus option joins PC/104 format
Data Device Corporation (DDC) is now offering single-function MIL-STD-1553 databus interface cards for the PC/104 format.
As you'd expect, this small component is also lighter weight".
The new BGA product is a plastic moulded device built on FR4 material that matches the temperature coefficient of all PC boards.
"This means our product will expand and contract at the same rate as the PC board to which it's attached, resulting in a mechanically reliable assembly", said Len Marro, Vice President of Engineering at DDC.
"These Micro-ACE models are the industry's smallest MIL-STD-1553 terminals; rated to operate over industrial temperatures (-40 to +85C) and are impervious to moisture", he added.
The BGA packaging is available in three u-ACE configurations, including remote terminal-only (RT) with 4K x 16bit RAM (BU-61740B3-202), and two bus controller/remote terminal/monitor (BC/RT/MT) versions with 4K x 16bit RAM (BU-61840B3-202) and with 64K x 17bit RAM (BU-61860B3-202).
All three devices feature the full range of architectural advancements found in Enhanced Mini-ACE products, including a highly autonomous BC; a choice of RT buffering modes; a selective message monitor; a highly autonomous built-in protocol and RAM self-test; and a choice of 10, 12, 16 or 20MHz clock frequencies.
Furthermore, Micro-ACE products are compliant with MIL-STD-1553A/B; STANAG 3838 and MIL-STD-1760.
Amir Massumi, Director of Marketing at DDC stated, "DDC has designed the Micro-ACE product line to be competitively priced for all applications, and is especially economical when purchased in large quantities".
