STMicroelectronics (NYSE: STM),
the leading supplier of MEMS for consumer and portable applications(1), has
integrated a 3-axis digital accelerometer with a 2-axis analog gyroscope in
a single module. The package-level integration of linear and angular motion
sensors improves performance, boosts reliability, reduces size and shrinks cost,
uncovering new possibilities for high-precision gesture and motion recognition
in mobile phones, remote controllers, personal navigation systems and other
MEMS motion sensors add an intuitive man-machine interface to mobile phones,
portable multimedia players, game controllers, personal navigation systems and
remote input devices, creating interaction by linking the user's wrist, arm,
and hand movements to applications, navigation within and between menus, the
movement of characters in a game and much more.
Robust and resistant to mechanical stress, the module leverages the same micromachining
technology process that ST has already successfully applied to more than 600
million motion sensors sold in the market. The device boasts excellent stability
over a wide operating temperature range (from -40 degrees C to 85 degrees C)
and a negligible level of output noise.
ST's low-power motion-sensing module combines a user-selectable full-scale
acceleration range of plus or minus 2g/plus or minus 4g/plus or minus 8g with
the industry's widest angular-rate detection from 30 to 6000 dps(2) along the
pitch and yaw axes(3). The gyroscope element provides two separate outputs for
each axis at the same time: an unamplified output value for high accuracy of
slow motion and a 4x amplification to detect and measure very fast gestures
Addressing power constraints in battery-operated portable devices, ST's new
MEMS module includes power-down and sleep modes and it can operate with any
supply voltage in the range of 2.7 to 3.6V. The device comes with built-in self-test
capability that allows the customer to verify the functioning of both sensors
after the assembly, without the need to move the board during testing.
"ST meets the market demand for cost-effective integration of multiple
motion sensors in a single module," said Sam Guilaume, CEO, Movea, the
industry leader in motion-sensing controllers. "With ST's new MEMS modules,
and our complementary SmartMotion(TM) technology, we will provide unequalled
motion-based solutions for user interfaces in remote controls, game pads, smartphones
and other consumer devices."
"The only company with high-volume production of gyroscopes and accelerometers
for consumer applications, ST now makes another significant step in MEMS consumerization
by introducing the market's first multiple-axis sensing device in a single package,"
said Benedetto Vigna, General Manager of STMicroelectronics' MEMS, Sensors and
High Performance Analog division. "Our customers will benefit from the
industry-unique combination of superior performance, compelling price points,
and large-scale production capacity at ST's dedicated 8-inch MEMS fab."
Samples of ST's LSM320HAY30 multi-axis motion sensor module are available now,
with mass production scheduled for Q1 2010. Unit pricing is $3.3 for quantities
over 50,000 pieces.
