The MC3479 Evaluation Board Quick Start Guide and Demo GENERAL DESCRIPTION sensor data shortly comes out in raw data count and SI unit accelerometer The MC3479 is a small form factor, measurements. An easy-to-use integrated digital output 3-axis demonstration on EV3479A using the accelerometer with a feature set optimized Arduino platform is depicted in this for cell phones and IoT product motion document. sensing. Applications include user interface control, gaming motion input, electronic compass tilt compensation for cell phones, MC3479 FEATURES game controllers, remote controls and Range, Sampling & Power portable media products. 2,4,8,12 or 16g range 16-bit single sample resolution The MC3479 features a dedicated motion 16-bit resolution with FIFO block which implements embedded 0.5 to 1000 Hz Output Data Rate algorithms to support any motion and 4 A typical Standby current shake detection, tilt/flip and tilt 35 position Low typical active current detection. Simple System Integration The EV3479A is a prebuilt circuit board with I2C interface, up to 1 MHz MC3479 LGA-12 3-axes sensor. The SPI Interface, up to 10 MHz MC3479 has internal sample rate from 0.5 220.92 mm 12-pin LGA package to 1000 samples / second and measures Single-chip 3D silicon MEMS acceleration with a wide usage range, from RoHS compliant +/-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.
