Introducing the new Atmel | SMART SAM C family


Atmel unveils an innovative 5V Cortex-M0+ MCU series with integrated peripheral touch controller.


Say hello to the Atmel | SMART SAM C family, the world’s first full 5V ARM Cortex-M0+-based MCU series with an integrated peripheral touch controller (PTC). The newest batch of MCUs innovatively combines 5V, DMA performance and a PTC with excellent moisture tolerance. Beyond that, the devices integrate advanced analog capability and offer EMI and ESD protection, making them ideal for the rapidly expanding smart appliance and industrial markets.

Atmel | SMART microcontrollers with PTC are currently in mass production at leading appliance manufacturers worldwide. By adding full 5V functionality on an ARM Cortex M0+ based core, along with upcoming support for the IEC 60730 Class B Safety Library, the SAM C lineup — including the SAM C20 and CAM C21 — is the perfect solution for partnering with industrial and white goods companies to power next-generation applications for the burgeoning Internet of Things.

Leveraging over two decades of MCU success, the latest series incorporates Atmel’s proprietary smart peripherals and Event System, not to mention are also pin and code-compatible to the SAM D and SAM L families. The SAM C is fully supported by Atmel’s free integrated development environment Atmel Studio and program examples and drivers for all peripherals are available through the Atmel Software Framework.

“Atmel leverages its leadership position in both MCU and touch with the new SAM C series,” explained Reza Kazerounian, Atmel SVP and GM, Microcontroller Business Unit. “The SAM C series uniquely combines support for 5V on a Cortex-M0+ based MCU with an integrated PTC, bringing an industry-first product to market for next-generation industrial and appliance applications.”

Among the notable features of the SAM C:

  • Expands the ARM Cortex-M0+ based MCU with hardware divide and square root accelerator at 48MHz
  • Large memories with SRAM up to 32KB and embedded Flash up to 256KB
  • Supports 2.7V to 5.5V operating voltage
  • Integrates the Atmel QTouch Peripheral Touch Controller
  • Incorporates Atmel’s proprietary DMA with SleepWalking, Event System and SERCOM
  • Dual 12-bit ADCs and a 16-bit Sigma Delta ADC
  • Dual CAN 2.0 with FD support

To help accelerate a designer’s development, the SAM C21 Xplained Pro is now selling for just $39. These boards include an embedded debugger and programmer and have a wide range of compatible extensions units. Standalone programmer debugger solutions supporting the SAM C family are also available from both Atmel and third parties.
