Creating a capacitive matrix keypad has never been simpler.
Complete a matrix keypad design (up to 4x4) with Infineon's CY8CMBR2016, a member of the CAPSENSE™ Express family. This complete approach, combining SmartSense auto-tuning with hardware configurable settings that eliminate the need for software tools, firmware, and device programming, dramatically reduces the design cycle.
The CY8CMBR2016 supports industry standard Keypad Scan and Truth Table host interface protocols, enabling customers to leverage their existing host processor firmware.
The CY8CMBR2016 is enabled with Infineons SmartSense Auto-tuning, the only in production tuning algorithm which automatically compensates for variance in temperature, noise, and overlay thickness.
The CY8CMBR2016 CAPSENSE™ Design Guide (AN73034), provides step-by-step guidance for the sensor design and layout process, which saves valuable engineering resources, test time, improves yield, and speeds time-to-volume.
