Freescale Semiconductor (NYSE: FSL) today introduced a new
micro-electromechanical system (MEMS) accelerometer featuring ultra-low
power consumption and a simple plug-and-play approach to tilt threshold
detection for use in physical tamper protection for smart meter
applications. Freescale's Xtrinsic MMA8491Q energy-efficient
accelerometer expands the portfolio to industrial markets requiring wide
pin pitch, visually inspectable leads and long product life cycles.
"Smart meters are proliferating with the emergence of the connected home
and smart grid, and protection from physical tampering is a critical
requirement," said Seyed Paransun, vice president and general manager of
Freescale's Sensor & Actuator Solutions Division. "Freescale is
addressing this need with a simple to use, cost-effective and extremely
low-power 3-axis accelerometer with specific embedded functionality."
Designed for applications requiring reduced complexity and advanced
system integration, the Xtrinsic MMA8491Q accelerometer for tilt
threshold sensing plays an integral role in Freescale's system-level
smart meter reference designs that detect physical tampering (introduced
Expo 2012 and Metering
Europe 2012). Movement of the meter is detected through the change
in tilt angle and communicated to the utility company as a tampering
The Xtrinsic MMA8491Q accelerometer was designed to be very flexible and
useful for a wide variety of applications beyond smart metering in which
orientation needs to be accurately measured - motion detection in gaming
consoles and home appliances, for example. The accelerometer also is
ideal for tracking asset handling in business and industrial settings
and can be employed in eHealth and portable health monitoring systems.

Xtrinsic MMA8491Q 3-axis accelerometer features
The Xtrinsic MMA8491Q accelerometer for tilt sensing features X-, Y- and
Z-axis tilt threshold detect outputs and operates with reduced power
capabilities that intelligently determine when a device should operate
in a low-power mode or shut off, helping prolong battery life.
