DUE R3 Development Board SAM3X8E32-bit ARM Learning Master …, Newcastle

Description 1 Since the board operates at 3 3 V the maximum voltage that can be applied to the I O pins is 3 3 V Supplying higher voltages e g 5 V to the I O pins may damage the board 2 Advantages of the ARM core Using a 32 bit ARM core is more powerful than the other Iduino cores previously used with the 8 AVR The main differences are One clock of 32 bits can process 32 bits of data CPU clock frequency is 84 MHz 96 KB SRAM 512 KB of flash memory A DMA controller to relieve the CPU of a large number of calculations Specifications Microcontroller SAM3X8E Operating voltage 3 3 V Input voltage recommended 7 12 V 7 12 V Input Voltage Limit 6 16 V 6 16 V 54 digital I O pins 12 of which provide PWM outputs Analogue input pin 12 Analogue output pin 2 DAC Total DC output current for all I O lines 130 mA DC current at 3 3 V pin 800 mA DC current at 5 V pin 800 mA Flash memory 512 KB all for user applications SRAM 96 KB two banks 64 KB and 32 KB Clock speed 84 MHzPackage includes 1 x DUE R3 Development Board
