Atmel ARM processor with internal oscillator and optional external oscillator (pads provided but not populated).

Key features include:

  • USB OTG (implemented on processor board)
  • USARTS – Four channels for implementation of SCI, SPI, and other popular communications protocols (TTL level signals, associated peripheral cards required for implementation on some protocols)
  • I2C / TWI – Two channels
  • Timer / Counters – Nine channel / 32 bit timer
  • PWM – Eight channel; 16 bit PWMs, including complementary pairs (PWMH / PWML) – also includes motion fault outputs
  • RTC – Real time clock with time / date capabilities
  • ATD – Sixteen channel, 12-bit ATD with on-board or external ATD reference
  • DAC – One 2-channel digital to analog converter
  • CAN – Two CAN channels
  • Ethernet – One Ethernet channel
  • SD Card and NAND Flash interface (via DPIP headers)
  • General Purpose I/O – 103 total I/O lines; can be configured for edge or level interrupt
  • Vsupply (processor and peripherals) – 3.3Volts only (as implemented on E3 Embedded PIEP)

Many signal pins can be remapped for alternate functions. For additional details refer to the SAM3X summary; Atmel document number: doc11057s.
