Atmel Automotive Solutions for Infotainment, HMI, Connectivity Applications

With their combination of different communication interfaces, Atmel MCUs are ideally suited for interfacing between a telematics module and an audio/video network such as Ethernet, and a control network like CAN or LIN. On the vehicle side, Atmel MCUs are available with both the audio/video network interface (Ethernet MAC) and with vehicle control interfaces (CAN and LIN), while you can support the telematics module connection through an integrated USB controller, including an integrated PHY. You can use Atmel System Basis Chips (SBC) to provide the needed vehicle control network transceiver and voltage regulator.

  • “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.
