The PSoC 4 can also be used for user interfaces that includes CapSense buttons that just work because of Cypress’ rigorous engineering and testing. The CapSense component configuration tool and SmartSense auto-tuning simplify designs and eliminate manual tuning. PSoC 4 can drive and control LEDs, segment LCDs, and integrate light sensor AFEs for auto dimming. Again the PSoC 4 low-power mode saves power consumption. The PSoC 4 is a one-chip, reliable, easy-to-use low power solution for user interfaces.
