MSP430FR2633 Microcontroller CapTIvate Electronic Lock and Keypad Reference Design

TIDM-CAPTIVATE-E-LOCK

Overview

This reference design demonstrates an ultra-low power capacitive touch panel solution powered by a single MSP430™ microcontroller (MCU) with CapTIvate™ technology. The use of self- and mutual-capacitance technology enables multifunctional capacitive touch panels (buttons and proximity sensors) to be used in electronic locks and other applications with various human-machine interfaces. This TI reference design also shows how to extend battery life by cyclically running the MSP430 CPU and switch between low-power and run modes.

characteristic

● 12 touch buttons with a proximity sensor for system wake and guard keys
● 12 LEDs for indicating touch operations
● Provide touch feedback and lock status through haptics and beeps
● Ultra-low standby power consumption
● Moisture-proof performance
