Support for the ATSAM4C16 within Atmel Studio 6.1 requires a device support package: DOWNLOAD

The Atmel SAM4C16 microcontroller is a system-on-chip solution for smart energy applications built around two high performance 32-bit ARM®Cortex®-M4 RISC processors. These devices operate at a maximum speed of 120 MHz and features 1Mbyte of embedded Flash, 152 Kbytes of SRAM and on-chip cache for each core. The dual ARM®Cortex®-M4 architecture allows for integration of application layer, communications layers and security functions in a single device, with the ability to extend program and data memory via a 16 bit external bus interface.
