My Technical specifications of the Arduino Doue board are..........
Microcontroller AT91SAM3X8E'n
Operating Voltage : 3.3V'n
Input Voltage (recommended) : 7-12V'n
Input Voltage (limits) : 6-20V'n
Digital I/O Pins : 54 (of which 12 provide PWM output)'n
Analog Input Pins : 12'n
Analog Outputs Pins : 2 (DAC)'n
Total DC Output Current on all I/O lines : 130 mA'n
DC Current for 3.3V Pin : 800 mA'n
DC Current for 5V Pin : 800 mA'n
Flash Memory : 512 KB all available for the user applications'n
SRAM : 96 KB (two banks: 64KB and 32KB)'n
Clock Speed : 84 MHz'n
ADVANTAGES OF THE ARM CORTEX-M3 MICROCONTROLLER'n
The Cortex-M3 offers more performance than the usual 8bits microntrollers found on other Arduino boards. In particular, the ARM Cortex-M3 allows'n:
A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock'n. (for more information look int type page'n).
CPU Clock at 84Mhz'n.
96 KBytes of SRAM'n.
512 KBytes of Flash memory for code'n.
a DMA controller, that can relieve the CPU from doing memory intensive tasks'n.
