描述
The Liquid Tolerant Capacitive Touch Keypad Design (TIDM-1021) is a reference design for implementing liquid tolerant capacitive touch human-machine interfaces (HMIs). It integrates TI's MSP430FR2633 microcontroller (MCU) featuring high performance CapTIvate™ touch technology with an optimized sensor layout design and software. This reference design demonstrates how to design capacitive touch hardware and software that can work reliably under liquid influence and pass challenging tests for conductive noise immunity.
特性- MSP430™ CapTIvate MCU for Liquid-Tolerant Capacitive-Touch Sensing
- Advanced Human Machine Interface Design with 12-Button Keypad
- 12 LEDs Driven by MSP430 CapTIvate MCU for Backlighting
- Passes IEC 61000-4-6 Conducted Noise Immunity Test at 3 Vrms Stress Level
- No False Touch Detection and Accurately Detect Touched Button under IPX5 Rating Test with AC Power
