Atmel AT91SAM3U4E (ARM-CM3) Board: 2x RS232, CAN, USB, SD Card US$149.00

Atmel AT91SAM3U4E (ARM-CM3) Board: 2x RS232, CAN, USB, SD Card

The Atmel AT91SAM3U4E Cortex-M3 core-based processor operates at 96 MHz clock frequency. The board features USB, I2C, MCI and USART interfaces, TFT-LCD, 96 I/O ports, EBI support SRAM, NOR and NAND Flash memory, etc. Plenty of software examples, which can be used in Keil MDK environment, are included on the CD-ROM.

  • Internal 256KB Flash, 48KB SRAM
  • 240x320 TFT LCD
  • Source code of example programs

Atmel AT91SAM3U ARM-CM3 Board Features

The connectors on the AT91SAM3U evaluation board provide easy access to many of the AT91SAM3U's on-chip peripherals.
  • Serial Port
  • A standard DB9 connector is on the AT91SAM3U board for the AT91SAM3U'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 AT91SAM3U 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 AT91SAM3U.
  • External Memory
  • The AT91SAM3U 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.

Development Environment

To compile, link and run applications on the AT91SAM3U Evaluation Board, you must install these products:

  • The Keil RealView MDK-ARM which includes the µVision Debugger and provides several example programs for the AT91SAM3U 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 included on CDROM.

The CD-ROM includes several example programs that are configured for the Embest AT91SAM3U Board.

All examples are configured for two µVision targets:

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

All examples use the same file structure:

  • Abstract.txt contains a short description of the example.
  • ATMEL SAM3U Series.s contains the startup code for the microcontroller.
  • STM32_Init.[c,h] contain the initialization of the microcontroller's peripherals.
  • Example dependent source code.
