MC3430 3-Axis Accelerometer
GENERAL DESCRIPTION
FEATURES
Preliminary Datasheet
The MC3430 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.
The sample rate of the MC3430 can be
programmed from 1 to 128 samples /
second. Even greater power savings can be
achieved by taking advantage of event
detection while the device is in a low power
mode. Specific orientation and gesture
conditions can trigger an interrupt to a
remote MCU, allowing the processor to
remain in a standby state until an event
occurs. Alternatively, the device supports
the reading of sample and event status via
polling.
