STMicroelectronics' Award-Winning eCompass Modules Being Used in Xiaomi Mi1S

Honored devices raise the bar in power consumption, performance and physical
size

GENEVA, Dec. 16, 2013 (GLOBE NEWSWIRE) -- STMicroelectronics (NYSE:STM), a
global semiconductor leader serving customers across the spectrum of
electronics applications, the world's top MEMS (Micro-Electro-Mechanical
Systems) manufacturer, and the leading supplier of MEMS devices for consumer
and mobile applications^1 has been an early bird in introducing its LSM303D
accelerometer and magnetometer combo module to Xiaomi (Mi1S) and other
emerging mobile phone makers in China.

ST's LSM303 eCompass family combines a 3-axis magnetic-field sensor and a
3-axis accelerometer in a single tiny 2x2x1mm module -- one of these, the
LSM303C was recently selected as "Device of the Year" by the MEMS Industry
Group. These devices accurately measure the direction and magnitude of
external magnetic fields while the module's accelerometer compensates for
tilt, ensuring a very accurate compass heading even when portable devices are
inclined. This capability provides the orientation function that is an
essential part of all of today's mobile devices.

"In smartphones and other mobile devices, every milliwatt matters," said
Benedetto Vigna, Executive Vice President and General Manager Analog, MEMS and
Sensors Group, STMicroelectronics. "The ST device meets minimal size
constraints and allows significant reductions in power consumption without
compromising performance in other areas. These advantages help manufacturers
to provide mobile devices that meet customer expectations while minimizing the
drain on the world's resources."

The low power consumption of the LSM303 Device of the Year is due to the use
of a phenomenon called Magneto Resistance (MR). MR is inherently more
power-efficient than alternative technologies, such as Hall Effect or Fluxgate
that are used in competitive eCompasses. ST engineers were able to design
devices that exploit this inherent power efficiency while still matching or
exceeding the performance of competitive devices in module size, full-scale
resolution and noise.

"Our MEMS technology continues to raise the bar in every quarter: power
consumption, performance, price, and physical size," said Vigna. "This, in
turn, allows dynamic new companies such as Xiaomi to raise the bar in their
own markets."

In addition to being the world's leading supplier of MEMS sensors, ST has
underpinned its continued strong leadership with over 900 MEMS-related patents
granted or pending worldwide.
