picoPower Technology
Reducing power consumption—maintaining performance
picoPower — Best MCU power budget
Atmel’s picoPower technology reduces power
consumption in both sleep and active mode. With
picoPower technology the embedded designer
can reduce the applications power consumption
while maintaining performance.
True 1.6 Volt Operation
AVR XMEGA offers true 1.6 Volt operation. All functions including ADC, DAC, Flash- and EEPROM
memories are all operating down to 1.6V. This allows safe operation directly from a 1.8V ±10% power
supply. It also enables deeper battery discharge to increase battery life.
Minimized Leakage Current
AVR XMEGA leakage current is only 100 nA while still maintaining
full RAM and register retention. This reduces power consumption
for applications spending most time in sleep mode.
Ultra Low Power 32 kHz Crystal Oscillator
AVR XMEGA’s Real Time Counter consumes only 500 nA while
running from a 32.768 kHz Crystal Oscillator.
Sleep modes
XMEGA has five different sleep modes to turn off unused modules
and reduce the power consumption in the application. Many
sleep modes makes it easy to find the perfect fit for the applica-
tion. The granularity is further enhanced by the innovative Power Reduction Register technology.
In idle sleep mode all peripherals operate while the CPU is sleeping
to reduce the power consumption. with
up to 50%, while event handling, communication and data input/output still run.
In power-save mode, XMEGA uses 650nA to run the Real Time Counter and have full SRAM and register
retention offering industry leading low power numbers. Enabling Watchdog and Brown Out adds only 1uA.
In power-down mode, XMEGA uses only 100nA with SRAM and register retetion, and 5us wake-up time
from pin change on any I/O pin and TWI address match.
Standby and extended standby sleep modes are identical to power-down and power-save, except the
external oscillator is kept running to reduce wake-up time.

System Performance
For Embedded systems, system performance is much more than a good MIPS number. It is important to
have powerful peripherals and features that allow the application to run smoothly with minimum power
consumption.
AVR CPU and Instruction Set
Auto increment /Decreme nt example
The AVR XMEGA uses the AVR RISC CPU which is
created for high level C code development. The instruc
tion set and CPU design are tuned for minimum code size
and maximum execution speed. Due to the true single
cycle execution of arithmetic and logic operations, AVR
microcontrollers perform close to 1 MIPS per MHz.
-
Central in the AVR architecture is the fast-access register file with 32 x 8-bit
general purpose working registers directly connected to the Arithmetic Logic
Unit. Within a single clock cycle the ALU can be fed two arbitrary registers, do a
requested operation, and write back the result.
The AVR XMEGA instruction set also support atomic 16-bit register access,
32-bit arithmetics, and have three 24-bit memory pointers.
Event System
The innovative AVR XMEGA Event System allow peripherals to send signals (events) directly to other peripherals
without involving the CPU. This ensures short and 100% predictable response time and at the same time
offloads the CPU.
Without Event System all Peripheral Requests need to be handled
by the CPU.
With Event System peripherals can send signals (events) to other
peripherals.

AES encryption and decryption.
There are no export limitations for the AVR XMEGA with crypto
engine, so using XMEGA for crypto function do not limit where you
can sell your product.
Analog and Digital Conversion
AVR XMEGA is highly integrated
with high performance 12-bit
ADC and DAC. The ADC sup-
port up to 2 million samples
per second. The DAC has con-
version rates up to 1 msps and
comes with built-in offset and
gain compensation. XMEGA

comparators with window func-
tion and flexible input selection.

Clock System
AVR XMEGA’s clock system allow flexible change of frequency. Dynamic Clock Switching allows the Embedded
Designer to tune performance and power consumption to fit the application. The internal PLL and prescaler
can be used to scale the clock sources dynamically up or down to further match application requirements.
With a built-in External Oscillator failure detection and internal RC oscillator with ± 1% accuracy over tempera-
ture and voltage, XMEGA offers the most safe, reliable and flexible clock system.
Input and Output
AVR XMEGA offers flexible I/O pin configuration with various sensing,
wake-up, synchronous/asynchronous, and driver settings. I/O pin’s
direction, value and logic state are read through separate registers.
The optional Slew-Rate limitation reduces EMI. Virtual ports regis
ters allow single cycle pin manipulation. This makes software for
bit-banging smaller and faster.
Interrupt Controller
AVR XMEGA include a multi level interrupt controller. Three priority
levels are supported, where higher level interrupts are prioritized and
executed before low level interrupts. All peripherals can be assigned
any interrupt level.
-
A higher level inte rrupt will halt execution of a lower level interrupt
routine. The lower level interr upt routine wil l continue and finish
after the highe r level interrupt routine finishes.
A second interrupt at an interrupt level already being ser vice d, will
pend until the first interrupt routine finishes.

Ease of use
AVR XMEGA microcontrollers benefit from the already existing AVR tools- and software chain. With a large
ecosystem including hardware, software, documentation, and partners available, embedded developers
will find it easy to succeed with the XMEGA!
AVR Tools — quality and low cost
Debugging and Programming
All XMEGA devices include a non-intrusive On-Chip Debug system that requires no device resources.
This gives real time access to all peripheral registers, data and program memories, and support unlimited
number of break points. XMEGA has a fast, serial programming interface for production line- or in system
programming. Using a bootloader XMEGA can receive flash upgrades in the field through any interface
without reset or halt of critical program execution. The crypto engine and a serial number in each device
ease implementation of safe crypto bootloaders, networking applications, authentication and life cycle
product tracking.
