Industry's thinnest full-functional tri-axis accelerometers

13-03-2015 | ROHM Semiconductor | Design & Manufacture

Rohm's Kionix group has announced the industry's first ultra-thin
full-functional tri-axis accelerometers, the KX112 (2mm x 2mm x 0.6mm) and
KXCJB (3mm x 3mm x 0.45mm), which are especially suitable for mobile,
wearable, health / medical and light-industrial applications.

"Among the many innovations and numerous firsts in the company's history,
Kionix was first to develop the tri-axis accelerometer in 2004, followed by
introduction of the first 'thin' 0.7mm tri-axis accelerometer in 2013," said
Nader Sadrzadeh, President and CEO, Kionix. "We're constantly pushing
physical and technological barriers. Our proprietary technology has allowed
us to break boundaries once again to introduce a new lineup of full-featured
'ultra-thin' low-power accelerometers. While these initial products (the
KX112 and KXCJB) are suited primarily for mobile, PC/tablet and wearable
applications, we continue to expand the portfolio to include automotive and
heavy-duty industrial applications."

The KX112 is part of Kionix's flagship family of tri-axis accelerometers. It
is the thinnest 2x2 accelerometer available, making it particularly
well-suited for the compact designs required in the health, medical and
wearable markets. Remarkably, in addition to its ultra-thin compact design,
it is one of the most full-featured accelerometers available. With 16-bits
of resolution and excellent stability, it features built-in digital
algorithms for detecting motion for power management, free fall for device
protection or warranty monitoring, an orientation engine for
portrait/landscape detection, and tap/double-tap for user interface
functionality. It also incorporates Kionix'sFlexSet technology, allowing
fine granularity for balancing power and performance. Most notably, the
KX112 has the largest FIFO/FILO buffer available on a mass-produced
accelerometer. With 2048 bytes available, the rest of the system can sleep
while it's recording more data than any other accelerometer on the market,
enabling superior power-savings and event context.

The KXCJB is the thinnest accelerometer available in any footprint,
measuring just 3mm x 3mm x 0.45mm thick. It supports the drive for thinner
smartphones, tablets, PCs and hard disk drives as well as compact wearables
such as activity monitors and smartwatches. The unique form-factor is half
the thickness of most accelerometers on the market. This brings the ability
to embed motion detection and motion sensing capabilities into a host of new
devices such as badges, access cards, and payment/smart cards, while also
opening up possibilities of maintaining low profiles when mounting on or in
glass, plastic and other thin structures, says the company.
