You can use the Cortex-M3 based ATSAM3U Evaluation Board to generate and test application programs for the ATMEL SAM3U Series microcontroller family. With this hands-on process, you can determine the hardware and software requirements for current and future product development.
The ATSAM3U Evaluation Board ships with the ATSAM3U device that is a superset of several other device variants of the ATMEL SAM3U microcontroller series. The ATSAM3U Board contains all the hardware components required in a single-chip ATSAM3U4E system.

• Serial Port
  A standard DB9 connector is on the ATSAM3U board for the ATSAM3U's built-in UART interfaces. This is a full duplex, serial port.
  
• CAN Port
  A standard DB9 connector for applications requiring CAN communications.
  
• USB Port
  A standard USB Type B connector for applications requiring USB communications.
• LCD Display
  A detachable, 240x320 TFT, color LCD display. You may use this graphic display device to show real-time debug and program status messages.
  On-board Battery
  A removable, lithium battery is included on the ATSAM3U to maintain power to the real-time clock when the board disconnects from the main power supply.
  Analog Voltage Control for ADC Input
  An adjustable analog voltage source for testing the Analog to Digital converter built into the ATSAM3U.
  
• External Memory
  The ATSAM3U board includes 1 Mbyte of external static RAM and 8 Mbytes of external SPI Flash memory.
  
• MicroSD Card Connector
  A MicroSD Card connector for developing applications requiring access to MicroSD Cards.
  
• ETM Trace Debug
  An ETM connector for on-chip debugging via the Embedded Trace Macrocell capabilities of the STM32F103 device.
  
• JTAG Download and Debug
  A JTAG on-chip debug interface, coupled with the ULINK USB-JTAG adapter, provides flash programming and real-time in-circuit emulation of the STM32F103 device.

• The RealView MDK-ARM which includes the ?Vision Debugger and provides several example programs for the ATSAM3U Board.
• The ATMEL SAM3U Series Software Library which provides a software foundation for the ATMEL SAM3U Series peripherals, it can be copied from CDROM we have tested.
• The example programs and project files for the board are accompanied with CDROM, developed by Embest.

• Simulator - where the program runs in the software simulator.
• FLASH - where the program runs from internal Flash located on the microcontroller.

• Text file (.txt) contains a short description of the example.
• Assemble Code (.s) contains the startup code and the initialization of the microcontroller's peripherals.  
• Example dependent source code and Keil uVision project file.
• Each example program is stored in a separate folder and can be copied to use under \Keil\ARM\BOARDS\Embest\ATSAM3U\ along with project files that help you quickly build the project and run the program.
• All example projects and programs are available in accompanied CDROM.
