| Current
ATLab products are
mainly focused on
human input devices
for PC, portable
multimedia devices,
home appliances
and cellular phones.
In addition, ATLab
has other emerging
devices such as
audio input/output
device and high-speed
digital video transceiver.

|
| Optical
mouse sensors, which
were originally
developed as Shared
R&D with SEMCO,
cover whole range
of wired and wireless,
PS2 and USB, and
400 CPI and 800
CPI. ATLab has product
leadership in simpler
(MCU function included
1-package chip from
2003), faster (800
CPI in 2004, 1600
CPI in 2005), and
smarter (10mA total
current in 2004,
minimized external
parts).
In addition to pre-matured
optical mouse market,
ATLab participates
in early market
with the optical
joystick sensor.
ATLab extends the
optical navigation
technology to input
devices for cellular
phones and portable
electronics. Gradual
evolution of cellular
phone and digital
media player cause
advent of graphical
user-interface.
Current navigation
buttons and micro-joystick
will be replaced
with optical joystick.
ATLab and his partners
have been preparing
to enable this market.
From late 2006,
slim mouse sets
and finger navigation
module were announced.
Rich intellectual
properties of over
50 registered patents
have protected to
defend ATLab optical
pointing devices
in market. From
2005, the patent
protection activities
were successfully
conducted in Korea.
And, ATLab will
extend to repeal
copy devices in
China. |

Digital
Contact Controller
(DCC)
|
| This
technology was named
DCC because of the
initial target to
replace a conventional
touch sensor. Now,
the DCC technology
is applied to touch
sensor and pressure
sensor (Digital
touch sensor - DigiSensor™).
Advantages of fully
digital circuit
enables to expand
various application
areas such as analog-to-digital
converter, integrated
MEMS, etc.
DigiSensor™ measures
impedance unbalancing
caused by finger
touch. Compared
with current keypads
in cellular phones,
DigiSensor™ makes
portable electronics
thinner and lighter.
After iPod adapted
touch sensor technology,
ATLab DigiSensor™
was also shipped
out since June 2005.
The unique architecture
of differential-signal
handling and logic
circuit only, which
differentiates in
10x less power and
10x faster speed,
makes longer battery
lifetime and immune
for external noises.
For examples of
taking time of cellular
phone, a strong
RF signal does not
affect to operation
of DigiSensor™,
but makes a mal-function
to a conventional
capacitive sensor.
Low current consumption
(5uA per sensing
channel) makes wake-up
by touch in touch
screen applications.
In addition to ASSP
approach, DigiSensor™
technology is available
for IP license.
Through IP license
and collaboration,
ATLab will add licensee’s
product that includes
DigiSensor™ IP.
SmartSensor™, which
includes DigiSensor™
and an 8-bit MCU,
is a good example.
SmartSensor™ is
very different from
MCU with capacitive
sensing peripherals
from competitors,
where MCU is fully
used to process
the capacitive function.
Since ATLab’s fully
digital architecture
DPI7 can provide
entire touch function,
embedded MCU in
SmartSensor™ is
used to assign other
system-control functions. |

Emerging
Devices
|
| ATLab
has a few audio/video
interface devices,
too. Integrated
audio processor
and GMDX™ (Giga-bit
Multimedia Data
eXpress) are examples.
Integrated audio
processor inputs
digital audio, digital
audio conditioning,
and analog audio
driver. And, GMDX™
includes SERDES
for digital audio/video/data
delivery, which
will be used for
home network, digital
multimedia data
delivery, and remote
PC, mega-pixel CCTV
applications. |
