ARM Cortex M3

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.

Internal 256KB Flash, 48KB SRAM 240x320 TFT LCD Source code of example program You can use the Cortex-M3 based AT91SAM3U 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 AT91SAM3U Evaluation Board ships with the AT91SAM3U device that is a superset of several other device variants of the ATMEL SAM3U microcontroller series. The AT91SAM3U Board contains all the hardware components required in a single-chip AT91SAM3U4E system.   Hardware Specifications: 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 ATSAM3U device.   Block Diagram: The hardware block diagram displays the input, configuration, power system, and User I/O on the board. This visual presentation helps you to understand the AT91SAM3U board components.   Technical Data: Parameter Description Supply Voltage 5 Volts DC (provided by power adapter) Supply Current 210mA typical, 320mA maximum XTAL Frequency 12 MHz Microcontroller AT91SAM3U4E LQFP 144 Pins Peripherals 2 × RS232 Interface, 1 × USB Device Interface (High-speed), 1 × 2.4” Color graphic display (240x320), 1 × MicroSD Memory Card connector, 1 × JTAG Interface, 5 × Push Buttons (Reset, Wake Up, Tampering, User), 2 × BNC Interface, 1 x RTC Unit with Battery, 1 × Analog Input (connected to potentiometer), 1 × Analog Output (connected to speaker by default) Board Size 135mm x 90mm (5.3" x 3.5") Weight 320g   Development Environment To compile, link and run applications on the AT91SAM3U Evaluation Board, you must install these products: The 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 accompanied with CDROM, developed by Embest.   Software and Examples Embest 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 AT91SAM3U Board. All examples are configured for two µVision targets at least: 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. Each example program is stored in a separate folder and can be copied to use under \Keil\ARM\BOARDS\Embest\AT91SAM3U\ 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.
