Avoid touching the component pins or any other metallic element on the board. Battery The ATSAM4C-EK ships with a 3V coin battery. This battery is not required for the board to start up as long as Jumper JP8 is closed.
After boot up, designers can run sample code or their own application, on the development kit. Users can download sample code and get technical support from the Atmel website. The ATSAM4C-EK is supported by the Atmel Software Framework (ASF) (http://www.atmel.com/tools/AVRSOFTWAREFRAMEWORK.aspx).
Evaluation Kit Hardware Overview This section introduces the Atmel SAM4C Evaluation Kit design. It introduces system-level concepts, such as power distribution, memory, and interface assignments. The Atmel SAM4C16C and SAM4C8C microcontrollers are system-on-chip solutions 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 feature up to 1 Mbyte of embedded Flash, 152 Kbytes of SRAM and on-chip cache for each core.
