Description
The LSM303DLHC is a system-in-package
featuring a 3D digital linear acceleration sensor
and a 3D digital magnetic sensor.
LSM303DLHC has linear acceleration full-scales
of ±2g / ±4g / ±8g / ±16g and a magnetic field full-
scale of ±1.3 / ±1.9 / ±2.5 / ±4.0 / ±4.7 / ±5.6 /
±8.1 gauss. All full-scales available are fully
selectable by the user.
LSM303DLHC includes an I²C serial bus interface
that supports standard and fast mode 100 kHz
and 400kHz. The system can be configured to
generate interrupt signals by inertial wake-
up/free-fall events as well as by the position of the
device itself. Thresholds and timing of interrupt
generators are programmable by the end user on
the fly. Magnetic and accelerometer parts can be
enabled or put into power-down mode separately.
The LSM303DLHC is available in a plastic land
grid array package (LGA) and is guaranteed to
operate over an extended temperature range from
-40 °C to +85 °C.
