MC3410 3-Axis Accelerometer
GENERAL DESCRIPTION
FEATURES
Datasheet
The MC3410 is a low-noise, integrated
digital output 3-axis accelerometer with a
feature set optimized for cell phones and
consumer product motion sensing.
Applications include user interface control,
gaming motion input, electronic compass tilt
compensation for cell phones, game
controllers, remote controls and portable
media products.
Accurate event detection is enabled with a
low noise architecture that minimizes false
triggering found in competing devices. Low
noise and low power are inherent in the
monolithic fabrication approach, where the
MEMS accelerometer is integrated in a
single-chip with the electronics integrated
circuit.
In the MC3410 the internal sample rate is
fixed at 1024 samples / second. Specific
orientation and gesture conditions can
trigger an interrupt to a remote MCU.
Alternatively, the device supports the
reading of sample and event status via
polling.
