STMicroelectronics (NYSE: STM),
the leading supplier of MEMS for consumer and portable applications(1), has
expanded its motion-sensor portfolio with a broad range of thirteen new single-
and two-axis gyroscopes. With more than a 50% shrink in volume over previous
ST devices, reduced power consumption, and an aggressive price, ST's new high-performance
angular-motion sensors open the way to a wide range of innovative consumer applications,
including gesture-controlled gaming and pointing devices, image stabilization
in digital video or still cameras, and assisted GPS navigation.
ST's newest single-axis (yaw) and two-axis (pitch-and-roll, pitch-and-yaw)(2)
MEMS gyroscopes fit in miniature packages of 3x5x1 and 4x5x1 mm3, respectively,
addressing the size constraints of today's and tomorrow's consumer applications.
Power consumption is another key factor, especially in battery-operated devices.
Therefore, ST's gyroscopes include a power-down mode (when the entire device
is switched off) and a sleep mode, in which part of the circuitry is turned
off to significantly reduce power consumption while allowing very fast turn-on
time and smart power cycling.
ST's new gyroscopes boast excellent stability over time and a wide temperature
range (down to 0.02 dps(3)/degrees C) eliminating the need for additional temperature
compensation in the application. Measurement precision is ensured with a negligible
level of output noise (down to 0.01 dps/sqrt(Hz), and wide bandwidth up to 560Hz,
ensuring high accuracy and repeatability.
ST's MEMS gyroscope family offers the industry's widest full-scale range, from
30 to 6,000 dps, covering a broad spectrum of applications that require high
resolution and stability over time and temperature.
The robust manufacturing process of ST's 8" fab and packaging technology
has already successfully built and delivered more than 600 million ST accelerometers
in applications ranging from gaming systems to cellular handsets. Like these
accelerometers, ST's high-performance MEMS gyroscopes are resistant to mechanical
stress and come with improved built-in self-test capability that allows the
customer to verify the functioning of the sensor after it has been assembled,
without the need to move the board during testing.
"Today, the gyroscope market for consumer applications is around $200
million(4) and it is dominated by non-MEMS companies," said Benedetto Vigna,
General Manager of STMicroelectronics' MEMS and Healthcare division. "ST's
third-generation gyroscopes benefit from the same winning attributes that have
helped us conquer the accelerometer market: proven manufacturing technology
and robust design. These features will help us trigger the 'consumerization
wave' for gyroscopes, and our in-house supply-chain management will enable ST
to meet the customer demand."
ST's new single- (yaw) and two-axis (pitch-and-roll, and pitch-and-yaw) MEMS
gyroscopes are now in high-volume production with unit pricing of $2.1 for the
2-axis gyro and $1.8 for the single-axis gyro, in quantities greater than fifty
