MICROCHIP MGC3140T-I/MV

Microchip's MGC3140 is a 3D gesture and motion tracking controller based on its patented GestIC technology, designed for consumer, industrial, and automotive applications. It leverages electric field near-field sensing to enable robust user interfaces through natural hand and finger movements. As a low-power mixed-signal configurable controller, it offers a range of powerful intelligent features — such as gesture recognition with adaptive operating frequency in noisy environments — to ensure robust performance. The on-chip Colibri gesture suite eliminates the need for host-side post-processing, reducing system power consumption and software development effort to facilitate faster time-to-market. The MGC3140 is a unique, high-performance single-chip gesture solution focused on automotive applications, delivering proximity sensing, gesture detection, and driver recognition capabilities to enable modern and compelling user interfaces.
