Kionix Introduces Low Power, Full-Featured

2x2x0.9mm Accelerometer with FIFO/FILO Buffer

The KX022 offers low current consumption and a full range of high-

performance embedded algorithms optimized for mobile applications

Ithaca, New York—Kionix, Inc. today announced the release of the KX022,

a 2x2x0.9mm tri-axis, robust accelerometer with integrated FIFO/FILO

buffer that maintains low power while offering a wide variety of embedded

algorithms for maximum functionality. Embedded features include tap

detection, orientation detection, activity monitoring, and motion wake-up

algorithms, as well as an internal voltage regulator and self-test function.

With an ultra-small package, high-performance embedded functionality, and

current consumption as low as 2µA, the KX022 is ideally suited for

smartphones, tablets, and health and fitness applications.

The KX022 also features a user-configurable, low-power, embedded motion

wake-up function, allowing the user to conserve battery life by powering

down other systems until needed. Combined with Kionix’s XAC sensor,

which provides outstanding stability with a market-leading combination of

improved shock, reflow, and thermal performance, as well as a decreased

need for production-line calibration, the KX022 provides customers with

substantial reductions in power, noise, and cost.

“Kionix continues to aggressively address customer requirements for a

small sensor footprint and for greater product functionality,” said Scott Miller,

Vice President of Engineering, Kionix. “As a result, we have successfully

enhanced our previous 2x2 offering by adding in a full range of embedded

algorithms and functionality and an integrated FIFO/FILO buffer, dropping

current consumption, and reducing noise, thereby making this part perfect

for mobile applications.”

KX022 features include:

 Low current consumption in all modes: 2 µA in standby, 10 µA at

normal resolution (25Hz ODR), and 130 µA for high resolution;

 User-selectable resolution and acceleration ranges at +/-2g, +/-4g or

+/-8g, as well as user-selectable Output Data Rate (ODR);

 Embedded FIFO/FILO buffer;

 Two interrupt registers;

 Digital high-pass filter outputs;

 Low noise for better resolution;

 I

C and SPI digital output;

 An internal voltage regulator that maintains constant internal

operating voltages over its 1.8 – 3.6V range of input supply;

 Up to 14-bit resolution for greater precision;

 Self-test function; and

 Embedded functionality, including tap detection, orientation, activity,

and motion wake-up algorithms.

Availability

Available in a 12-pin, LGA, plastic package, the KX022 will be sampling to

qualified customers during Q1 2013. For more information, please email:
