Austria microsystems has introduced the AS3665, a new
funlight LED driver that features better lighting effects
in mobile phones and other consumer applications. The AS3665
delivers sharp color, smooth color effects and high brightness,
and suitable for the applications such as mobile phones,
MP3 players, mobile computers, portable game stations, speaker
boxes, toys and any audio equipment into a true eyecatcher.
The AS3665 offers nine LED channels with up to 25mA per
channel. A 12bit PWM for each of the nine channels delivers
smooth color effects allowing linear, logarithmic and ratiometric
fading effects. The PWM generators have three sequencers
and a 1.5kbit memory that allows storing and processing
astonishing and complex light patterns without the need
for external processors or interaction. The AS3665 allows
easy command based programming of all light patterns. To
ensure true colors during operation the AS3665 implements
several color correction features like automatic RGB color
correction by temperature.
AS3665 audio synchronization feature enables colorful programmable
light patterns. With this feature, the color LEDs blink,
fade and change color smoothly in time with the device's
audio input like music or ring tones. The AS3665 synchronizes
the LEDs based on the music input. The audio synchronization
of the light patterns can be freely adjusted giving a freedom
to differentiate and define unique color response fitting
to any type of music from heavy beats of hard rock to soft
lyrics.
"The mobile phone market is fast moving and customers
expect products that stand out. They want to put their own
personal touch onto the phone," the product planning
team of Samsung Mobile Communication division commented.
"Austria microsystems' AS3665 LED Driver IC enables
us to be faster to market by reducing development time and
easily create light effects never seen before."
To optimize battery lifetime the AS3665 design includes
various power save features. Each channel operates with
less the 50mV dropout voltage at 10mA powered by a high
efficiency 150mA charge pump with automatic switching between
1:1, 1:1.5 and 1:2 mode. To optimize power consumption driving
RGB LEDs, three of the nine channels offer programmable
rail switching to choose between battery and CP voltage
for high efficiency allowing independent supply of red and
blue/green LEDs.
To accelerate system implementation, the AS3665 offers
easy design-in capability with minimal software programming.
Additionally a software tool allows fast command based development
of light patterns which is as easy as drawing lines on paper.
The software output is a compiled file which can be used
immediately with the AS3665.
"Austria microsystems has always been a leap ahead
in bringing exciting new functionality to market for mobile
phone manufacturers and other consumer electronics. Our
AS3665 funlight driver enables systems designers to offer
users more fun and functionality than ever before. This
new product truly brings light into the sound of portable
devices," said Bruce Ulrich Marketing Director of Consumer
and Communication BU. "The AS3665 joins Austria microsystems'
broad portfolio of lighting products of flashlight, backlight,
funlight, and dot matrix drivers, as well as powerful Lighting
Management Units."
