Human Interfaces Designing by Adding a modern, intuitive user interface improves its ease-of-use, functionality and aesthetics. Graphics displays, touch interactivity and audio prompts add a modern, updated look and feel to any design. Creating human interfaces for new or legacy designs need solutions that create a high-impact user interface incorporating the latest in touch sensing and graphical display technologies.These solutions must be easy to integrate and lower total system cost. Touch sensing interfaces such as keys/sliders and touch screens are fast becoming an alternative to traditional push-button switch user interfaces owing to their many benefits − elegant and stylish designs, lower manufacturing costs achieved by lowering costs of molds, tooling and assembly, and increased reliability via fewer moving components. Application designers migrating to touch sensing interfaces require robust, low-cost and power-efficient solutions that are easy to integrate. Digital displays improve the user interface of just about any application. Segmented LCDs have historically been a popular choice of display technology and continue to grow in a variety of medical and industrial applications. Also, a significant rise in the use of graphical displays such as TFT, OLED and CSTN in consumer, appliance and automotive applications. Users prefer intuitive menus, vivid graphics, touch panel interaction and in some case the ability to interact remotely with a system. Designers migrating toward graphical displays face several challenges such as cost of components associated with driving the display, complexity of software needed for updating graphics, battery life and remote connectivity. Touch Sensing Solutions Keys & Sliders Longer battery life with extremely Low Power MCUs Sensing through metal, plastic or glass High noise immunity and low emissions Lower system cost with broad MCU portfolio Turnkey analog resistive controllers for lowest system cost Highly flexible projected capacitive solution with low cost MCU implementation Fully processed and reliable touch coordinates Multi-touch and gesture capable Low power solutions with wide operating voltag Capacitive Touch Sense Capacitive sensing is becoming more prevalent and in demand for consumer applications. Touch sensing has become an alternative to traditional push button switch user interfaces, because it requires no mechanical movement, and it enables a completely sealed and modern-looking design.

Graphical Displays
We offer varying levels of solutions to drive everything from simple monochrome LCDs-16x2, 16x4, 20x4, 64x128 GLCD to full color WVGA user interfaces. Up to WVGA (800x480) resolution Up to 16 bit per pixel (65,536 colors) Integrated graphics acceleration units and display controller High performance with integrated Ethernet and CAN for remote interfaces Integrated USB OTG and Touch sensing
Audio Processing Solutions Adding audio capability in the form of music playback or voice guidance, greatly improves the user experience of a product. Audio is useful in product language localization and providing assistance to the visually impaired. Audio prompts are very useful in applications requiring the end users visual attention elsewhere, such as automotive.
Our platforms allow the designer to include speech or audio interfaces, enabling functions such as: Generation of tones, alarms and musical notes Recording and playback of audio information Graphic equalizer GPS driven Audio for Locomotives
