Kionix's KXR94 Makes Navigation a "Walk in the Park"

Ithaca, New York - Wednesday, June 11, 2007 - Kionix, Inc., a global leader in
the design and manufacture of MEMS inertial sensors, announced today the availability
of its highest-performing accelerometer product, the KXR94.

Eric Eisenhut, Vice President for Sales and Marketing, indicates, "This new sensor
surpasses the excellent specifications of our high-performing KXM52 series. The
KXR94 has appreciably less drift over temperature, which minimizes application errors.

Additionally, it can be programmed to a ±1g range on all three axes, providing the best resolution for electronic compass tilt correction. It also features very low noise density at on all three axes, which reduces double integration errors for customers who are using the part for dead reckoning. The performance of the KXR94 over temperature makes it the best tri-axis choice on the market for navigation applications."

The KXR94 series of parts is delivered in an industry-standard, DFN, plastic package
measuring 5x5x1.2mm. The part is distinguished further by its multiplexed analog or
digital SPI interface, current consumption typically less than 1mA at 3.3V, and an
internal low pass filter on all three outputs to reduce any high-frequency vibrational

The KXR94 is completely pin compatible with Kionix's KXM52, making it a simple, dropin
replacement part. At the same time, customers will benefit from the reduction in
package height from 1.8mm to 1.2mm.

This RoHS compliant sensor may be factory programmed to accept supply voltages from
2.5 to 5.25V and sensitivity from ±1 to 5g. It is fabricated utilizing Kionix's highperformance, capacitance-based technology and proprietary plasma-micromachining
process. This deep-silicon, reactive ion etching (DRIE) technology has enabled Kionix
to create a high-performance accelerometer that meets the novel requirements of both
advanced consumer electronics and automotive applications.
