Advantages of XMega processor

• Runs at 32mhz with INTERNAL clock - no crystal/resonator needed
• Separate 'boot' section (more memory for application)
• Lower cost - ATXMega32E5 costs less than ATMega328 (TQFP-32)
• At least 2 serial ports available
• Additional I/O pins with more pin 'modes'
  'Totem pole', open drain/source, pull up/down, edge/level
• 12-bit A:D with differential A:D conversion and adjustable gain
• Advanced interrupt support (3 levels), any pin can be an interrupt
• More pins can be set up as PWM outputs
