Reminders: 1) Due board runs at 3.3 V. The maximum voltage that the I/O pins can tolerate is 3.3 V. Providing higher voltages, like 5V to an I/O pin could damage the board. 2) ARM core strengths: The use of 32-bit ARM core is more powerful than th previous use of the other Iduino core 8 AVR. The main differences are: • 32 bits at a clock can process 32 bits of data. • CPU clock frequency of 84 MHz • 96 SRAM KBytes • 512 Flash KBytes • A DMA controller, can reduce the pressure on the CPU to do a lot of computing Specifications: • Microcontroller: AT91SAM3X8E • Operating voltage: 3.3 V • Input voltage (recommended): 7 – 12 V • Input voltage (limits): 6 – 16 V • Digital I/O pins: 54 (of which 12 provide PWM output) • Analog input pins: 12 • Analog outputs pins: 2 (DAC) • Total DC output current on all I/O lines: 130 mA • DC current for 3.3 V pin: 800 mA • DC current for 5 V pin: 800 mA • Flash memory: 512 KB all available for the user applications • SRAM: 96 KB (two banks: 64 KB and 32 KB) • Clock speed: 84 MHz
