The maXTouch™ mXT768E mutual capacitance touchscreen controller represents a significant milestone in the tablet revolution. While the first generation of tablets utilized multiple chips to scan the touchscreen, the mXT768E offers a true single-chip 32-bit solution for tablets up to 12-inches in a 6mm x 6mm package. This remarkable innovation enables an 80% reduction in power consumption compared to competing solutions, as well as space savings that enable sleeker industrial design.Despite its small size, the mXT768E packs a powerful punch. It features the new maXTouch E Series capacitive touch engine, which supports higher fidelity touch sensing, faster responsiveness, lower power consumption, and a broader choice of displays and touch sensor configurations. Advanced touch processing - enabled by its powerful 32-bit AVR core - allows the mXT768E to ignore unintentional touches caused by a gripping hand or resting palm, while correctly interpreting up to sixteen concurrent touches. For high-precision operation, the device also includes algorithms to identify and track a narrow stylus input.
