ATMEL SAM3U ARM Cortex-M3 Evaluation board The ATSAM3U ARM-CM3 Board is an ARM embedded evaluation board produced by Embest, integrate the ATMEL Cortex-M3 core-based processor ATSAM3U4E, operating at 96 MHz frequency. The board features USB, I2C, MCI interface, TFT-LCD, USART interface, 96 I/O port, EBI support SRAM/NOR/NAND memory, etc. Plenty of software examples, which can be used in Keil MDK environment, are accompanied in CDROM.


Hardware Specifications:
The connectors on the ATSAM3U evaluation board provide easy access to many of the ATSAM3U's on-chip peripherals.
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 ATMEL SAM3U device.

Technical Data


Development Environment
To compile, link and run applications on the ATSAM3U Evaluation Board, you must install these products:
The RealView MDK-ARM which includes the μVision 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.
Software and Examples
mbest Provides plenty of software examples for this evaluation board, all in source code. These software examples can be debugged under the popular Keil MDK (Microcontroller Development Kit) environments, making practical use of the board's peripherals.

The CDROM includes several example programs that are configured for the Embest ATSAM3U Board.

All examples are configured for two μVision targets at least:
o Simulator - where the program runs in the software simulator.
o FLASH - where the program runs from internal Flash located on the microcontroller.


All examples use the same file attribution and/or structure:
o Text file (.txt) contains a short description of the example.
o Assemble Code (.s) contains the startup code and the initialization of the microcontroller's peripherals.   
o Example dependent source code and Keil uVision project file.
o 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.
