Arduino Due Board provides clock pulses of 3.579 Mhz frequency. Because these are very common and inexpensive they are used in many other applications, for example, DTMF generators. It is a common clock for the HT9170B DTMF decoder. It uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time to provide a stable clock signal for digital integrated circuits and to stabilize frequencies for radio transmitters and receivers. The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins, 12 analog inputs, 4 UARTs, A 84 MHz clock, An USB OTG capable connection, 2 DAC, 2 TWI, A power jack, An SPI header, A JTAG header, A reset button and an erase button. onboard CAN controller for realizing CAN Protocol. The board contains everything needed to support the microcontroller, simply connect it to a computer with a micro-USB cable or power it with an AC-to-DC adapter or battery to get started. The Due is compatible with all Arduino shields that work at 3.3v and are compliant with the 1.0 Arduino pinout. The Arduino Due can be powered via the USB connector or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery.
