AVR® MICROCONTROLLERS

AVR XMEGA
8/16-bit High Performance Low Power Flash Microcontrollers

Atmel® introduces the XMEGA™ – a brand new AVR® microcontroller. With the same acclaimed
characteristics as the established AVR devices, the XMEGA operates from just 1.6 volt with up to
32 MIPS at 32 MHz.
Time critical real-time and interrupt driven applications become safer, more responsive, and predictable with XMEGA. AVR XMEGA features a CPU independent Event System, DMA controller, and Multilevel Interrupt Controller. With multiple time bases, extreme communication bandwidth and special
features like Cryptography support, XMEGA is number one for demanding 8- and 16-bit embedded
applications. At the same time XMEGA’s 2nd generation picoPower™ technology with only 100 nA
sleep current is the best choice for battery operated and energy critical applications.
XMEGA features
 Innovative Event System for fast, CPU independent inter-peripheral communication
 4-channel DMA Controller boosts MCU performance
 100% predictable timing
 High-speed 12-bit ADC and DAC
 Fast AES and DES crypto engine
 2nd generation of picoPower technology
AVR XMEGA microcontrollers are the perfect solution for a wide range of applications:
• Industrial control

• ZigBee®

• HVAC

• Optical transceivers

• Climate control

• Power tools

• Wireless encryption

• Medical applications

• Hand-held battery

• Sensors

• Networking

• Alarm systems

• Factory automation

• Motor control

• Metering

• White goods

AVR XMEGA Microcontroller

The Complete Microcontroller - XMEGA
Atmel’s AVR has grown to become the preferred MCU for demanding embedded projects [1]. With the
brand new XMEGA operating from only 1.6 volts with speeds up to 32 MHz, designers now get even more
performance and low power capabilities. With an impressive list of features and a drastically increased
peripheral throughput, the CPU can spend less time handling peripherals and even more time in sleep
mode.

Programmable Multilevel Interrupt Controller
All peripherals have software selectable interrupt levels and different interrupt vectors. Important interrupts
are executed immediately and tasks are prioritized with minimum latency.
Performance Peripherals
XMEGA is packed with new, improved peripherals including:
• multiple analog comparators

• multiple USARTs, TWIs and SPIs

• several 16-bit Timer/Counters with 8 unique

2 μA current consumption. The XMEGA also

incorporates true 1.6 volt operation and elements like dynamic clock switching, and frequency scaling for
optimal power management.

XMEGA – Extreme Compatibility
XMEGA uses the same instruction set as existing
AVR products, and code can easily be reused.
Compilers and development tools platforms are
the same for all AVR microcontrollers.
All XMEGA family members are pin and 100%
code compatible. Designers can easily reuse
both source and binary code in all projects
when different XMEGA devices are used. This
significantly reduces development effort and
time to market.

The XMEGA Product Range
All XMEGA devices operate from 1.6 to 3.6 volts and up to 32 MHz. The first XMEGA devices range from
44 to 100 pins and from 16 to 384 KB of Flash memory.
