Touch Remote Control with CapTivate Technology
Created: May 25, 2018
The touch remote control enabled with CapTIvate™ technology demonstrates a capacitive-touch solution based on a single MSP430™ microcontroller (MCU) with CapTIvate technology. This design uses self- and mutual-capacitance technology to enable a multifunctional, capacitive-touch panel (buttons, slider, gesture pad, grip sensor and proximity sensor) for smart TV, set top box, and sound system remote applications for future application extensions with various communication interfaces available. The design allows operators to extend the battery life by the low-power active and standby modes.
The MSP430FR2633 is an ultra-low-power, FRAM-based MSP430 MCU equipped with CapTIvate technology. The device includes 15.5KB of FRAM and 4KB of RAM making it capable of supporting complex, capacitive-touch applications. The integration of CapTIvate technology with the MSP430 peripheral set and a large memory footprint makes the MSP430FR2633 optimized for low-power user interface (UI) development.
