Cypress Semiconductor introduced the CapSense Express capacitive touch sensing device for button and slider replacement. The device enables designers to implement up to 10 buttons and/or sliders in as little as five minutes with no coding. The PSoC Express visual embedded system design tool and CapSense Express configuration tool allow designers to monitor and tune the performance of the buttons and sliders in real time using a graphical user interface. The CY8C201X0 and CY8C201X2 CapSense Express devices offer up to ten capacitive and/or general purpose I/Os (GPIOs), allowing design flexibility to implement combinations of buttons, sliders, and general purpose functions like LED control and interrupt outputs. For battery powered applications, the devices offer low power consumption of 1 mA active current and 2.6 µA in sleep mode. The new devices offer a wide operating voltage of 2.40 V to 5.25 V and an industrial temperature range of -40°C to 85°C. In addition, 2 Kb of Flash memory and an I²C communication interface are provided so designers can choose whether to store tuning values in Flash or load them over I²C at power-up.
