GENERAL DESCRIPTION 

The MC3419 is a small form factor, 
integrated digital output 3-axis 
accelerometer with a feature set optimized 
for cell phones and IoT 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.  

 

The MC3419 features a dedicated motion 
block which implements embedded 
algorithms to support “any motion” and 
shake detection, tilt/flip and tilt 35 position 
detection.  

 

The EV3419A is a prebuilt circuit board with 
MC3419 LGA-12 3-axes sensor. The 
MC3419 has internal sample rate from 

0.5 

to 1000 

samples / second and measures 

acceleration with a wide usage range, from 
+/-2g up to +/-16g, and 16-bit high precision 
ADC output, which is easy to fit on top of 
the microcontroller, such as an Arduino. 
The accelerometer communicates via 
I2C/SPI and gives out motion detection or 
sample acquisition conditions to trigger an 
interrupt toward an MCU.  

 

The sensor data is easily readable by 
connecting DVDD to 3.3V, GND to ground, 
and SCL/SDA pins to your Arduino I2C 
clock and data pin respectively. Download 
the MC3419 library from GitHub onto the 
board, run the example sketch, and then  

 

 

sensor data shortly comes out in raw data 
count and SI unit accelerometer 
measurements. An easy-to-use 
demonstration on EV3419A using the 
Arduino platform is depicted in this 
document.
