Data Device Corporation (DDC) has expanded its Enhanced Mini-Ace series of products with the world's first 3.3V fully integrated MIL-STD-1553 BC/RT/MT terminal.

Data Device Corporation (DDC) has expanded its Enhanced Mini-Ace series of products with the world's first 3.3V fully integrated MIL-STD-1553 BC/RT/MT terminal.

Referred to as the "Mini-Ace Mark3" series, this new design requires only a 3.3V power supply, and at the same time is the smallest 1553 terminal packaged in a ceramic quad flat package (CQFP).

"With the predominant trend to 3.3V logic, the Mini-Ace Mark3 terminal eliminates the need for a 5V power supply, providing a significant advantage for military and avionic systems", noted Mike Glass, Data Bus Technical Marketing Manager at DDC.

"Designers can now take advantage of an all 3.3V system, saving the cost, weight, and space of a 5V power supply while also saving precious board real-estate with Mini-Ace Mark3's smaller package.

Furthermore, the 3.3V Mini-Ace Mark3 uses less power than the 5V only Enhanced Mini-Ace" he added.

At 0.77in2, the Mini-Ace Mark3 uses 23% less board space than present ceramic package designs and has a low profile of 0.13in height.

Furthermore, the Mini-Ace Mark3 CQFP is a robust hermetic design ready to support applications at military or industrial temperature ranges, and is available with numerous environmental screening options.

Mini-Ace Mark3 1553 terminals are available in various configurations.

Designers can choose from RT-only or full BC/RT/MT functionality, 4K x 16 or 64K x 17bit memory compliment, and either a PCI or generic processor back-end interface.

The Mini-Ace Mark3 can work with 8, 16, or 32bit processors with little or no glue logic, while the PCI Mini-Ace Mark3 series provides a 32bit, 33MHz, 3.3V signalling PCI target interface.

The PCI version offers a distinct improvement over multicomponent implementations, because it uses less real estate and it simplifies the engineer's logic design by eliminating the need for a custom-programmed FPGA to connect to embedded PCIbuses.

Mini-Ace Mark3 devices are 100% compatible with the architectural features found in DDC's Enhanced Mini-Ace and PCI Enhanced Mini-Ace products, including a highly autonomous intelligent BC, a choice of RT buffering modes, a selective message monitor; an autonomous built-in protocol and RAM self-test; and a choice of 10, 12, 16 or 20MHz clock frequencies.

Moreover, the devices are fully compatible with DDC's suite of drivers, library and GUI software.

All Mini-Ace Mark3 products are compliant with MIL-STD-1553A/B, STANAG 3838 and MIL-STD-1760.
