Atmel Automotive Solutions for Infotainment, HMI, Connectivity Applications

Atmel’s broad automotive portfolio includes many solutions for the modern automotive centerstack display. A key differentiating element of the centerstack display is the touchscreen. It acts as the human-machine interface to many vehicle functions and features, and Atmel’s MaxTouch products provide for a responsive and robust interface experience. You can perform common post-processing of touch interactions, such as gesture calculations and filter algorithms that meet current automotive design requirements, within the MaxTouch controller. You can also perform more advanced post processing, such as character recognition, with the addition of a separate host processor from Atmel’s MCU line-up connected to the MaxTouch controller through a serial interface. When you require dedicated capacitive-touch buttons, sliders, and wheels, an Atmel MCU in combination with QTouch Library firmware can be used, with the added benefit of also providing connectivity to the vehicle communication network, if needed.

Features and Benefits

Touchscreen

  • Automotive qualified products — All touchscreen controllers are AEC-Q100 qualified, some parts are qualified up to +105°C (Auto grade 2).
  • Broad touchscreen controller portfolio — Products range from 143 up to 3432 channels, addressing everything from small touchpads up to 20-inch (50.8-cm) touchscreens.
  • Embedded DSP based touch engine — Touch acquisition in less than 10msec enables character recognition on the host processor.
  • Embedded CPU for post processing — Advanced noise filtering to support single layer, shield-less sensors, embeded single and dual-touch gestures, and the rejection of unintended touches.
  • Unlimited, unambiguous touch identification — Multi-touch support of 16 simultaneous touches.
  • High voltage mode for the highest SNR — Support gloved finger touch, finger tip, and back of finger touches.

Touch for BSW (buttons, sliders, and wheels) and proximity detection:

  • Developer's choice — QTouch Library can be used to develop single-chip solutions for many control applications, or to reduce chip count in more complex applications.
  • Multitude of combinations — Developers have the latitude to implement buttons, sliders, and wheels (BSW) in a variety of combinations on a single interface.
  • Broad controller support — QTouch Library supports Atmel | SMART™ ARM-based MCUs as well as tinyAVR®, megaAVR®, XMEGA™, and the UC3C 32-bit AVR.
  • Numerous channels — The chip supports up to 64 sense channels for maximum interface sensitivity. 256-level sliders and wheels require only three channels.
  • Three acquisition methods — The QTouch Library supports three patented capacitive touch acquisition methods: QTouchQTouchADC and QMatrix®.
  • Precise operation — Atmel Adjacent Key Suppression® (AKS®) technology enables unambiguous detection of button touches for maximum precision.
  • Prevent bounce — Full debouncing reports for touch buttons helps ensure single, clean contacts.
  • Common API — A common API across all library versions simplifies development.

Microcontrollers:

  • Automotive Qualified — Atmel® automotive microcontrollers are fully automotive-qualified (AEC Q100) and available in different temperature ranges, with some devices operating up to +150°C ambient temperature (AECQ100 Grade0).
  • “Zero Defect” Qualify — Atmel microcontrollers are fully-engineered to fulfill OEMs’ quality requirements towards zero defects.
  • Broad Portfolio — From 8-bit AVR microcontrollers up through 32-bit devices, our wide range of microcontrollers deliver the technical features, advanced architecture, and dependable design that’s right for your application.  LIN and CAN communications are both supported within the portfolio, as well as support for the emerging use of USB and Ethernet within the automobile.  This portfolio also includes complete System-in-Package (SiP) solutions which integrate a microcontroller along with a voltage regulator, a network interface, and other differentiated functions into a single cost-effective and space-saving package.
  • Impressive Performance / Power Efficiency — Leverages a long history in both real-time systems and in low-power technology. Atmel uses architectural features such as Direct Memory Access (DMA) and Event Support, and complex peripherals, such as the Peripheral Touch Controller, across the microcontroller portfolio to provide products that meet demanding performance requirements while operating within tight power budgets.
  • Complete Development Eco-System – All microcontrollers are supported by a complete set of development tools, including a low-cost option based on Atmel Studio that provides a common environment across the entire portfolio.  In addition, production-quality software is available from 3rd parties, where needed, to complete the development ecosystem.

LIN:

  • Broad portfolio — The Atmel portfolio starts with simple LIN Transceivers and progresses up to highly integrated System in Packages (SiPs) ensure that you can select the correct IC for your application.
  • Superior performance — All parts are based on the Atmel LIN IP, that delivers excellent electromagnetic interference (EMI) and electrostatic discharge (ESD) performance.
  • Maximum integration — The Atmel innovative mixed-signal BCD-on-SOI (bipolar, CMOS, DMOS on silicon-on-insulator) technology, called SMART-I.S™, is used for many body electronics and powertrain devices. It enables high integration, extended EMC performance, and high-temperature capability.
