HW Module for Capacitive Touch Sensing
• Buttons, Sliders, and Wheels
• Mutual- and self-capacitive touch
• Can run both at the same time
• Self-(re)calibrating, no tuning needed
• No external components needed
• Excellent conducted immunity (CI)
• Built-in hardware filtering
• Passes 10V CI*
• Low standby power consumption
• 4µ stand with wake-up touch
• Low CPU utilization
• Autonomous operation
• Non blocking interrupt behavior
• High channel count
• Up to 256 mutual cap channels
• Up to 32 self cap channels
* 100K series resistor might be needed in some designs
