Simultaneous Scans
– Support for High-Resolution Sliders With
>1024 Points
– 30-cm Proximity Sensing
– Reliability
– Increased Immunity to Power Line, RF, and
Other Environmental Noise
– Built-in Spread Spectrum, Automatic Tuning,
Noise Filtering, and Debouncing Algorithms
– Enables Reliable Touch Solutions With 10-V
RMS Common-Mode Noise, 4-kV Electrical
Fast Transients, and 15-kV Electrostatic
Discharge, Allowing for IEC‑61000-4-6, IEC-
61000-4-4, and IEC‑61000-4-2 Compliance
– Reduced RF Emissions to Simplify Electrical
Designs
– Support for Metal Touch and Water Rejection
Designs
– Flexibility
– Up to 16 Self-Capacitance and 64 Mutual-
Capacitance Electrodes
– Mix and Match Self- and Mutual-Capacitive
Electrodes in the Same Design
– Supports Multitouch Functionality
– Wide Range of Capacitance Detection, Wide
Electrode Range of 0 to 300 pF
– Low Power
– <0.9 µA/Button in Wake-on-Touch Mode,
Where Capacitive Measurement and Touch
Detection is Done by Hardware State
Machine While CPU is Asleep
– Wake-on-Touch State Machine Allows
Electrode Scanning While CPU is Asleep
– Hardware Acceleration for Environmental
Compensation, Filtering, and Threshold
Detection
– Ease of Use
– CapTIvate Design Center, PC GUI Lets
Engineers Design and Tune Capacitive
Buttons in Real Time Without Having to Write
Code
– CapTIvate Software Library in ROM Provides
Ample FRAM for Customer Application
