The versatile device can be used to power a wide range of applications, including utility metering, home automation, climate control, industrial control, sports equipment, toys, eToken, medical, power tools and fire alarm systems.

To accelerate development with the ATxmega128B1, Atmel offers the XMEGA-B1 Xplained, a hardware-based platform that allows engineers to more easily evaluate the device.

Aside from the ATxmega128B1 microcontroller (MCU), key XMEGA-B1 Xplained specs include:

  • 4×40 transflective LCD module with backlight
  • Transfer data over the USB full/low speed device interface
  • Read a light sensor with the ADC
  • Read a temperature sensor with the ADC
  • Measure external voltage input with ADC
  • Measure potentiometer voltage with ADC
  • Read status of the 4 Atmel QTouch buttons from AT42QT1040 QTouch device
  • 4 LEDs to show status information
  • Read/write data to the 64Mbit Atmel DataFlash
  • Program the kit via USB bootloader or an Atmel programmer
  • Expand the board with Xplained top modules
