Description
Introduction to MSA311:
The *MSA311* is a compact, low-power 3-axis accelerometer designed for motion sensing in consumer electronics, wearables, and IoT devices. It measures acceleration along X, Y, and Z axes with high resolution (up to ±16g) and features digital output via I²C/SPI interfaces. Key specifications include:
- Resolution: 12/14-bit selectable
- Operating Voltage: 1.62V–3.6V
- Low Power: 6μA in low-power mode
- Built-in Features: Tap detection, free-fall detection, and motion interrupts
Applications include screen rotation, step counting, and gesture recognition. Its small form factor (2mm × 2mm) and robust performance make it ideal for space-constrained designs.
For setup, configure registers via I²C/SPI, then read data from output registers. Refer to the datasheet for detailed register maps and timing diagrams.
