Agilent Technologies Inc. has announced the release of what it claims to be the industry's first 3.3V LED dot-matrix, alphanumeric "smart" device for use in medical and test equipment, printers, scanners, copy machines and routers, line cards, and other networking equipment.

The HCMS-39XX displays operate directly from a 3.3V supply making them compatible with standard 3.3V microprocessors and logic circuits. The displays are also claimed to provide the intelligence needed to interface directly with the microprocessor or microcontroller without the need for extra interface components or voltage converters.

"With the delivery of the first 3.3V LED smart displays, we have made the designing of new systems easier by eliminating the need for a separate 5V supply," said Soo-Ghee Lee, VP and GM of Agilent's Optoelectronic Product Division.

The serial interface devices feature a 5-by-7 pixel format that displays the full range of uppercase and lowercase ASCII characters, Katakana, and custom user-defined characters that are dot-addressable. The displays are stackable in both x- and y-directions, making them suitable for creating compact, high-density information displays.

The HCMS-39XX displays are supplied in four and eight character versions, each with a choice of 0.15-inch or 0.20-inch character height and red, orange, and green LEDs. AlInGaP versions are available for applications that require extra high brightness.

Each display module incorporates a CMOS IC complete with refresh and constant current LED drive circuitry. The display is dot-addressable, and programmable features include blanking, multilevel dimming, and sleep mode.
