Cypress Semiconductor has announced a new line of CapSense capacitive touch-sensing devices with low-power 1,8 V operation. The CY8C20xx6A devices replace mechanical buttons and sliders, offering attractive, functional interface options for designers.
The new family also offers fast response time with the most precise scanning of any CapSense devices.
With high immunity to conducted and radiated noise, as well as robust waterproofing, the new devices enable reliable touch-sensing operation in applications such as white goods, home appliances, printers, computers and TVs/monitors. The CY8C20xx6A family offers the new patent-pending SmartSense solution, which automatically calibrates capacitive-sensing parameters during the design process, cutting development time.
The new devices have up to 36 general-purpose I/Os (GPIOs) to implement multiple CapSense interfaces. Leveraging the PSoC programmable system-on-chip architecture, a single new CapSense device can also manage functions such as motor control, intelligent sensing, LED control and more – a capability called CapSense Plus. Additionally, the new devices include a full-speed USB interface. The CY8C20xx6A device line is available in multiple configurations and packages, including a small form factor 3 x 3 x 0,6 mm 16-pin QFN.
The new CY8C20xx6A CapSense devices are supported by the CY3280-20X66 CapSense development kit, which includes a development board with ports for linear slider, radial slider, trackpad, simple button, matrixed button and breadboard plug-in modules. Each package option of the devices is also supported by a CY3250-20xx6 ICE pod kit that includes emulator pods and feet, enabling a designer to perform system-level debugging.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
