If the content of the internal Flash has been erased, it can ® be reprogrammed recovered to the state as it was when shipped by Atmel using Atmel SAM-BA In-system Programmer available on the Atmel website (www.atmel.com). The binary file of the demo software is also available on the Atmel website.
Page 5 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 SAM4C32-EK is supported by the Atmel Software Framework (ASF) which is also available on the Atmel website.
Page 6 This section introduces the SAM4C32-EK design. It introduces system-level concepts, such as power distribution, memory, and interface assignments. The Atmel SAM4C32 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 feature up to 2 Mbyte of embedded Flash, 256 Kbytes of SRAM and on-chip cache for each core.

Page 21 3.9.3 Temperature Sensor The Atmel AT30TS75 temperature sensor converts temperatures from -40°C to +125°C to a digital word and provides a typical accuracy of ±0.5°C over the operating temperature range of 0°C to +85°C. The device is factory calibrated and requires no external components to help provide a cost effective solution. To reduce current consumption and save power, the AT30TS75 features a shutdown mode that turns off all internal circuitry except for the internal power-on reset and serial interface circuits.
