These MCUs combine 5V, DMA performance and a PTC with excellent moisture tolerance. They also integrate advanced analogue capability and offer EMI and ESD protection, suiting them for the smart appliance and industrial markets. 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 new SAM C MCUs target industrial and white goods companies.
The series incorporates the company’s proprietary smart peripherals and Event System, and are pin and code-compatible to the SAM D and SAM L series. The SAM C is 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.
The SAM C Series; expands the ARM Cortex-M0+ based MCU with hardware divide and square root accelerator at 48 MHz; it offers large memories: SRAM up to 32 kB, and embedded Flash up to 256 kB; and supports 2.7V to 5.5V operating voltage. As well as the peripheral touch controller, the series incorporates company’s proprietary DMA with SleepWalking, Event System and SERCOM; dual 12-bit ADCs and a 16-bit Sigma Delta ADC; and dual CAN 2.0 with FD support.
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.
