Kionix Announces Breakthrough Micro-Amp Magnetic Gyro
Solution for Consumer Electronics Applications
KMX61G with integrated sensor fusion software offers an 80% to 90%
reduction in power compared to traditional consumer gyros
Ithaca, NY—Kionix, Inc., a leading supplier of MEMS inertial sensors and
software solutions, today announced the KMX61G – a high performance
accelerometer-magnetometer sensor with industry-leading sensor fusion
software that delivers the world’s first highly accurate gyro emulation using
just 550µA of power. This represents dramatic savings in power compared to
traditional gyros, providing new options for consumer electronics product
designers.
Now a single 6-axis device can provide 9-axis accelerometer, magnetometer
(e-compass) and gyro outputs with a power profile that enables applications
previously unreachable using traditional 9-axis solutions.
“We see many applications in mobile devices that can benefit from gyroscope
functionality but do not require the extreme performance of a traditional
gyro.” said Jeremie Bouchaud, Director & Sr. Principal Analyst, iHS iSuppli.
“The magnetic gyroscope can meet these needs well while offering power,
cost and size benefits that are very attractive.”
In addition to Kionix’s proprietary calibration and sensor fusion algorithms,
the KMX61G includes a range of capabilities to enable precise control of the
sensor including 512-byte FIFO buffer with watermarking, embedded
temperature sensor and a low-power, embedded motion wake-up function.

With applicability to the large and rapidly growing smartphone, tablet, and
health and fitness devices market, the KMX61G is well-suited to help design
engineers achieve new levels of product performance.
“Customers have told us they would like to include gyro capabilities in their
product designs, but in many cases are unable to due to power, size or cost
constraints.” said Scott Miller, Vice President of Engineering, Kionix. “We are
excited that through the combination of high-performance hardware and
innovative software the KMX61G delivers breakthroughs in all of these areas,
providing our customers with a range of new design possibilities.”
For customers only requiring high performance e-compass capabilities
without a gyro output, Kionix is also introducing the KMX61, a 6-axis e-
compass device with auto-calibration software. The KMX61 delivers high
sensitivity (0.05 µT/count) with stability over temperature (± 0.05 %/ºC)
and is well-suited for a range of smartphone, tablet and health and fitness
applications.
