Introducing the SAM DA1 series of Atmel | SMART MCUs

Atmel launches automotive grade ARM Cortex-M0+-based MCUs with capacitive touch hardware support for HMI and LIN applications.

Just in time for Embedded World 2015, Atmel has officially launched its next-generation family of automotive-qualified ARM Cortex-M0+-based MCUs with an integrated peripheral touch controller (PTC) for capacitive touch applications.


The SAM DA1 is the first series in this Atmel | SMART MCU automotive-qualified product family, operating at a maximum frequency of 48MHz and reaching a 2.14 Coremark/MHz. Atmel’s SAM DA1 series is ideal for capacitive touch button, slider, wheel or proximity sensing applications and offers high analog performance for greater front-end flexibility. The new devices are available down to a very compact QFN 5x5mm package with wettable flanks for automated optical inspection.

Eliminating external components and offering more robust features, devices in the SAM DA1 series come with 32 to 64 pins, up to 64KB of Flash, 8KB of SRAM and 2KB read-while-write Flash and are qualified according to the AEC Q-100 Grade 2 (-40 to +105°C).


“As a leader in both automotive touch and LIN solutions, we are committed to bringing innovative, cost-effective solutions to next-generation vehicles,” explained Atmel’s VP of Automotive Matthias Kaestner. “With a comprehensive peripheral set for connectivity and state-of-the-art touch support, the SAM DA1 series allows system designers to perfect the human-machine interface in the automobile with capacitive touch. We are committed to offering a wide range of cost-optimized auto-qualified products for in-vehicle networking, infotainment connectivity and body electronics.”

Key features of the SAM DA1 series include:

  • Atmel | SMART ARM Cortex-M0+-based processor
  • 45 DMIPS
  • Vcc 2.7 to 3.63V
  • 16kB to 64kB Flash; 32 to 64 pins
  • Up to six SERCOM (Serial Communication Interface), USB, I2S
  • Peripheral Touch Controller
  • Complex PWM
  • AEC Q100 Grade 2 Qualified

To accelerate the design development, the ATSAMDA1-XPRO development kit is available to support the new devices. Furthermore, the new SAM DA1 series is also supported by Atmel Studio, Atmel Software Framework and debuggers.


Interested? The company is currently working on the SAM DA1 series with lead customers, with general sampling slated to begin at the end of April 2015. In the meantime, you can head over to the MCU family’s page here.
