ST Micro launches MEMS Gyroscopes
STMicroelectronics is sampling a new family of single-
and multi-axis MEMS (Micro-Electro-Mechanical Systems) gyroscopes.
Silicon material's mechanical properties and semiconductor
properties are well utilized to make this single device
MEMS with both electronics and micrometer sized machines.
These devices are suggested for detecting angular-motion
in human-machine interface applications such as personal
and car navigation systems, and image stabilization for
digital still and video cameras.
Gyroscopes are said to be complementing devices for acceleration
sensors used in above said applications.
These MEMS gyroscopes offer full-scale range, from 30 to
6,000 dps (degrees per second). The sensors can provide
two separate outputs for each axis at the same time - an
un-amplified output value for general detection of angular
motion and a 4x amplification for high-resolution measurements.
ST's new gyroscopes boast excellent stability over a wide
temperature range and time, with variation typically lower
than 0.05dps/°C for zero-rate level, eliminating the
need for further temperature compensation in the application.
Measurement precision is ensured with the negligible level
of noise that affects the output signal (0.014dps/sqrt(Hz)
at 30dps full-scale).
These mechanical stress-resistant MEMS gyroscopes can operate
in supply voltage range of 2.7 to 3.6 V.
Examples include LPR503AL, a two-axis pitch-and-roll gyroscope
with 30dps and 120dps full scales, and LPY550AL, a two-axis
pitch-and-yaw gyroscope with 500dps and 2,000dps full scales.
Package: 5x5 mm LGA package.
Availability: Mass volumes in Q3 2009
Price: Each $2.5 for 10K pieces
