The MPR121’s most distinctive product advantage over competing solutions is its low power consumption. This enables designers to add a touch interface to their system without compromising the system power requirements. Secondly, it is easy to implement with no software required, few layout constraints, and added flexibility. Auto-configuration makes setting and configuring the electrodes easier than competing solutions. Also, because the 12 channels can be set and controlled independently, the electrodes can be arranged with different shapes and ranges.
