Description
TIDM-CAPTIVATE-64-BUTTON is a TI Designs 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 only 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 pith CAPTIVATE-FR2633 target MCU module
- CapTIvate Design Center supports real-time sensor tuning with a host PC
