The sensor comes in a land-grid array (LGA) type
package with a footprint of 3mm x 3mm and a height
of merely 0.9mm.

to provide more information.
The BMA150 provides a digital 10bit output signal in
SPI or I²C format. Via serial interface command the
full measurement range can be chosen to ±2g, ±4g
or ±8g. A second-order filter with a pole-frequency
of 1500Hz is included to provide preconditioning
of the measured acceleration signal. The maximum
data conversion rate is 3KHz.
Additional digital filtering is possible to improve S/N
ratio (down to 25Hz bandwidth). Typical noise level
and quantization lead to a resolution of 4mg.
The current consumption is typically 200µA at a
supply voltage of 2.5V. In addition there are several
features implemented to support the host system in
reducing power consumption.
Parallel to normal operation where acceleration
values are provided to the output registers the
BMA150 is capable to perform internal compu-
tations of the results. The customer is enabled
to define specific criteria, e.g. high-g or low-g
thresholds but also criteria for the recognition of
smooth motion profiles. The sensor can inform the
host system about the violation of one of these
criteria via an interrupt pin. This feature can be used
for many purposes, e.g. to wake-up the host system
from a global sleep mode, to signalise a shock
situation or to indicate free fall.
The BMA150 also features self-test capability. Thus,
it allows for testing of the complete signal evaluation
path including the micromachined sensor structure
and the evaluation ASIC.
