New Kionix Low-Power Digital Accelerometer Offers Industry-Leading Stability and Performance

LAS VEGAS — Kionix, Inc. today announced the KXCJ9, a new low-power, low-cost, low-noise micro-electromechanical systems (MEMS) accelerometer with a novel tri-axis sense element. Pin-to-pin compatible with Kionix’s popular KXTI9 and KXTF9, the KXCJ9 offers customers unmatched quality and functionality at an affordable price. Combining high performance, reduced active and passive power consumption, and unmatched stability, the KXCJ9 promises to be the “go-to” part for consumer electronics manufacturers in high-volume markets.

“Our customers face intense pressures to pack more functionality into products that are more power-efficient and cost less,” said Kenneth Salky, executive vice president of sales and marketing, Kionix, Inc. “We designed the KXCJ9 to hit these performance-power-price benchmarks—without sacrificing features.”

The KXCJ9, though low cost, is a feature-rich product. It offers:

  • Low current consumption in all modes: 2 µA in standby, 10 µA at low resolution, and 135 µA at high resolution;
  • A user-configurable wake-up function, which lets customers conserve battery power;
  • A new sense element representing an evolution of Kionix’s leading MEMS technology. Designed and produced in Kionix’s newly expanded fab, the sense element provides excellent performance over temperature, in shock tests and in reflow. These attributes combine to produce a new level of device stability for today’s high-volume consumer electronics markets;
  • User-selectable g ranges of ±2, ±4 or ±8g, as well as user-selectable Output Data Rate (ODR);
  • Communication on the I2C digital serial interface bus for easy system integration, both eliminating analog-to-digital converter requirements and providing direct communication with system microcontrollers;
  • An internal voltage regulator that maintains constant internal operating voltages over its 1.8 – 3.6V range of input supply. This results in stable operating characteristics and virtually undetectable ratiometric error; and
  • Accelerometer outputs with up to 14-bit resolution for greater precision.

Availability

The KXCJ9 is now sampling to qualified customers. It is available in a 3 x 3 x 0.9mm, 10-pin, LGA plastic package. For more information, please email: salesna@kionix.com or contact the Kionix sales office nearest you.
