Description

The LSM320HAY30 is a low-power system-in-

package featuring a 3D digital linear acceleration

sensor and a 2D analog angular rate pitch and

yaw sensor. It provides excellent temperature

stability and high resolution over an extended

operating temperature range (-40°C to +85°C).

ST’s family of sensor modules leverages the

robust and mature manufacturing process already

used for the production of micromachined

accelerometers. The LSM320HAY30 has a

dynamically user-selectable full-scale

acceleration range of ±2

g/±4 g/±8 g, and an

angular rate of ±300 dps capable of detecting

rates with a -3 dB bandwidth up to 140 Hz along

pitch and yaw axes. The LSM320HAY30 is

capable of measuring linear accelerations with

output data rates from 0.5 Hz up to 1 kHz. The

embedded self-test capability allows the user to

check the functioning of each sensor in the final

application. The device can be configured to

generate an interrupt signal by inertial

wakeup/free-fall events as well as by the position

of the device itself. Several years ago ST

successfully pioneered the use of this package for

accelerometers. Today, ST has the widest

manufacturing capability and strongest expertise

in the world for production of sensors in plastic

LGA packages.
