The Noise Tolerant Capacitive Touch HMI design (TIDM-CAPTOUCHEMCREF) is a reference design for implementing noise tolerant capacitive touch human-machine interfaces (HMIs). It integrates TI's MSP430FR2633 microcontroller (MCU) featuring high performance CapTIvate™ touch technology with the TPS7A4533 linear regulator and UCC28910 flyback switcher. This reference design demonstrates how to design hardware and software that can pass challenging system level tests for conducted RF immunity, electrical fast transient/burst immunity, and electrostatic discharge immunity by applying a three-sided design approach consisting of hardware design techniques, CapTIvate technology peripheral features and software signal processing.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
