Avago Technologies, the world's largest privately held semiconductor company, today expanded its line of smart dot-matrix 5 by 7 LED alphanumeric displays to include the industry's first smart displays with 'eye catching' blue characters in a thin rectangular 8-character package. Avago's HCMS-2919 and HCMS-2976 LED displays are about the width of a AAA battery and ideal for those designers looking to enhance the appearance of their products with blue display characters that are easy to see in all lighting conditions.

The HCMS-2919 and HCMS-2976 displays are driven by on-board low-power complementary metal oxide silicon (CMOS) ICs, and can be directly interfaced with a microprocessor, thus eliminating the need for cumbersome interface components. These displays, which help to reduce design costs and are easy to use, can be used in a wide variety of consumer, industrial and communications applications. Some of these applications include remote battery-powered instruments, copy machines, printers, gaming machines, routers, audio/video applications, and test and measurement equipment.

"This latest addition to our family of smart dot-matrix LED products is available in eight character packages which can be stacked vertically and horizontally for displays requiring higher character counts," said Cheng Kai Chong, worldwide marketing manager for Avago Technologies' Optoelectronic Products Division. "Since we are the first supplier of blue smart displays, we can leverage our expertise in this area by providing our customers with customized the application support."

Features

· Gallium nitride (GaN) blue (460 nm dominant wavelength) smart displays

· Transistor-transistor logic (TTL)-compatible serial interface allows higher character count information displays with a minimum of data lines

· 5 by 7 pixel format can display upper and lower case Roman letters, Katakana, and a wide range of user-defined characters

· Daylight viewable

· Typical brightness: 170 microcandela (ucd) per character (all pixels illuminated)

· Easy-to-implement brightness control and operation over the extended -40 C to +85 C temperature range

· Eight character packages are sturdy and wave-solderable for low-cost automated assembly

In addition to the new GaN blue smart displays, Avago also offers HCMS-29xx displays in the following configurations:

· 1 by 4, 0.15-inch character

· 1 by 8, 0.15-inch character

· 2 by 8, 0.15-inch character

· 1 by 4, 0.20-inch character

· 1 by 8, 0.20-inch character versions in AlGaAs red (637 nm), high-efficiency red (627 nm), orange (602 nm), yellow (585 nm) and green (574 nm)

All versions use the same ASIC and have the same package dimensions and pin configurations, making it simple to upgrade to a blue display.
