The CY8CMBR2016 supports industry standard "keypad scan" and "truth table" host interface protocols, enabling customers to leverage their existing host processor firmware. The device also features multi-touch, perfect for matrix applications that require simultaneous button presses to enter various user interface modes. The CY8CMBR2016 operates over a 1.71 to 5.5 V range making it suitable for a wide range of regulated and unregulated battery applications, and a supply current in run mode as low as 15µA/button. It is aimed at applications such as security panels, card reader keypads, biometric scanner keypads, fire alarm control panels, thermostats, home appliances as well as any system requiring up to 16 individual CapSense buttons.
