These smart diagnostic features support the Automotive Safety Integrity Level (ASIL) classification index as defined by the ISO 26262 Functional Safety Specification for Passenger Vehicles.<\/p>\n<p>The new devices feature technology that enables adaptive touch utilising self-capacitance and mutual-capacitance measurements, so all touches are recognised and false-touch detections are avoided.<\/p>\n<p>They also feature Microchip\u2019s proprietary new signal-shaping technology that significantly lowers emissions to help large touchscreens using maXTouch controllers meet CISPR-25 Level 5 requirements for electromagnetic interference in automobiles.<\/p>\n<p>The new touch controllers also meet automotive temperature grade 3 (-40 to +85\u00b0C) and grade 2 (-40 to +105\u00b0C) operating ranges and are AEC-Q100 qualified.<\/p>\n<p>With the addition of the new maXTouch touchscreen controllers, Microchip provides full scalability to customers, offering the industry\u2019s only complete and growing portfolio of automotive-qualified touchscreen controllers for the use of various screen sizes.<\/p>\n<p>Developers can design multiple platforms from small touchpads to large displays in the same development environment with the same host software interface and quality user experience.
