The world’s first full 5V ARM Cortex-M0+-based MCU family with integrated Peripheral Touch Controller (PTC) has been introduced by Atmel. The SAM C family innovatively combines 5V, DMA performance and a PTC with outstanding moisture tolerance. The devices also integrate advanced analogue capability and offer EMI and ESD protection, making them suitable for the rapidly expanding smart appliance and industrial markets.

Featuring 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 MCUs are a suitable solution for partnering with industrial and white goods companies to power next-gen applications.

The devices incorporate the company’s proprietary smart peripherals and Event System, and are pin and code-compatible with the SAM D and SAM L series. The MCUs are fully supported by Atmel’s free integrated development environment, Atmel Studio, and can utilise program examples and drivers within the Atmel Software Framework.

“Atmel leverages its leadership position in both MCU and touch with the SAM C series,” said Reza Kazerounian, Senior Vice President and General Manager, MCU Business Unit, Atmel. “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-gen industrial and appliance applications.”

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

Engineering samples for the Atmel SAM C series is available now. The IEC 60730 Class B Compliance Safety Library will be available when the devices are in production.
