A tiny 3 x 3 x 1 mm package provides the home for a 3-axis accelerometer and a 32-bit microcontroller (MCU). Part of an approach that Freescale Semiconductor calls its Xtrinsic sensing solutions, the MMA9550L addresses both the sensing and computing needs of the rapidly proliferating touch sensing applications. As if this wasn’t enough, the package also holds a power management capability as well as I2C and SPI connectivity.
Since the MCU is the company’s well-established ColdFire MCU, software can be easily developed for Xtrinsic products using CodeWarrior tools. Internal algorithms simplify implementing freefall detection, tilt and 3D orientation detection, tap and double tap detection, dead reckoning, shock, vibration and sudden motion detection. Specific capabilities for targeted consumer applications include 14-bit resolution, low-noise and low-power consumption.
