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 predict-
able with XMEGA. AVR XMEGA features a CPU independent Event System, DMA controller, and Mul-
tilevel 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.

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.

Event System
Like a reflex in the human body, the innovative
XMEGA Event System enables inter-peripheral
communication without CPU or DMA usage. This

ensures 100% predictable and short response
time. Up to 8 simultaneous events or interrupt
conditions in the peripherals can automatically

Real 12-bit ADC and DAC
For high analog accuracy the XMEGA features high-speed 12-bit analog peripherals. Capable of up to 2
Msps, XMEGA’s ADCs deliver the fastest sample rate and most accurate result compared to conventional
MCUs. Since XMEGA also features two 12-bit digital-to-analog converters (DAC) with up to 1 Msps and
four advanced analog comparators, XMEGA microcontrollers have leading analog integration.
DMA Controller
A 4-channel DMA Controller enables fast, CPU

independent data transfer that significantly boosts
performance. The DMA Controller in XMEGA
with DM A
handles transfers between all combinations of
data memories and peripherals. The AVR CPU
register file and multiple bus layers ensures that

the data bus is always accessible for the XMEGA DMA Controller.
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
• several 16-bit Timer/Counters with 8 unique
time bases
• multiple USARTs, TWIs and SPIs

• IrDA
• Fast AES and DES crypto engine.

be the industry leader in low power designs.
With the 2nd generation picoPower technology,
XMEGA MCUs run a Real-Time Counter, Watch-

Durab ility
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.
