Intelligence and Control for Demanding Environments

Whether you are designing large, complex electronic systems or smaller, independent applications, we offer a wide range of cost-effective, top quality products with fully functional design kits for in-vehicle networking, infotainment connectivity and body electronics.

Focus Applications

  • 8bit Microcontrollers for Body, Safety and High-Temperature
    Atmel AVR microcontrollers deliver the power, performance, and flexibility you need to support a wide range of automotive applications. Small yet powerful, our wide range of advanced 8-bit AVR microcontrollers deliver the technical features, advanced architecture, and dependable design that's right for your application. Many Automotive AVR Microcontrollers are also offered in a grade 0, High-Temperature rating (-40C / 150C).
  • Capacitive Touch Sensing – Button Sliders and Wheels
    Most of the Automotive AVRs offer support for capacitive touch sensing functionality through the Qtouch library in combination with the powerful core and rich peripheral set.
  • In-Vehicle Infotainment, Ethernet-AVB and Audio processing
    Atmel ǀ SMART ARM-based Microcontrollers focus on in-vehicle infotainment connectivity for Audio Amplifiers, Telematic Control Units or Head Units. The SAM V Microcontroller series provides the best combination of connectivity interfaces including Ethernet AVB, MediaLB, USB and CAN-FD along with the highest performance ARM Cortex-M core delivering up to 1500 CoreMarks.

Key Features

Atmel ǀ SMART ARM Cortex-M7 based Flash Microcontrollers
  • Highest Performance – Up to 1500 CoreMarks thanks to the Cortex-M7 clocked at up to 300MHz coupled with unprecedented DSP performance.
  • Infotainment and Ethernet-AVB Connectivity – The SAM V71 embeds an Ethernet MAC with specific hardware support for Audio Video Bridging (AVB). Credit-based traffic shaping implemented in hardware within the MAC to avoid involving the CPU.
  • CAN-FD – Latest CAN 2.0 and CAN Flexible Datarate (FD) controller for higher bandwidth.
  • Low Power Backup
Atmel Automotive AVR Microcontrollers
  • High performance — Executing powerful instructions in a single clock cycle, Atmel's 8-bit Automotive AVR microcontrollers achieve throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
  • Code protection — Available on AVR32 Microcontrollers, Atmel FlashVault lets you partially program and lock flash memory for secure on-chip storage. Code stored in FlashVault will execute as normal, but cannot be read, copied or debugged. It can carry software such as math libraries or encryption algorithms to potentially untrustworthy environments where the rest of the source code can be developed and debugged.
  • Built-in voltage protection — The on-chip voltage regulator with short-circuit monitoring interface featured in several 8-bit microcontrollers ensures reliable operation and extends the useful life of the device and the product it controls.
  • Impressive power efficiency — Thanks to more than a decade of research, Atmel picoPower technology reduces microcontroller power usage in both sleep and active mode to achieve the industry's lowest power consumption numbers.
