Design files

Overview

TIDM-CAPTIVATE-64-BUTTON is a reference design for an ultra-low-power touch panel with 64 buttons that can be controlled by a single MSP microcontroller (MCU) with CapTIvate™ technology. The design uses mutual capacitance technology to enable all 64 buttons to be tightly packed and controlled with only 16 MCU pins. The touch panel is designed to easily interface with the CAPTIVATE-FR2633 MCU target module included in the MSP-CAPT-FR2633 MCU development kit.

Features
  • Single-touch and multitouch detection
  • Mutual capacitance technology enables 64 buttons with 16 microcontroller pins
  • More than 100 samples-per-second and 15-ms typical response time with code size/response time optimization
  • 1.75-µA-per-button average current with low-power optimization and 0.23-µA-per-button average current with wake-on-touch mode
  • Easy plug-and-play with CAPTIVATE-FR2633 target MCU module 
  • CapTIvate design center supports real-time sensor tuning with a host PC
