# AVR XMEGA devices include:  2nd generation of picoPower technology
# Innovative Event System for fast, CPU independent inter-peripheral communication
# 4-channel DMA Controller boosts MCU performance
# 100% predictable timing
# Fast 12-bit ADC and DAC
# Fast Cryptography support for AES and DES

AVR XMEGA microcontrollers have the same acclaimed characteristics as the established AVR devices, and operates from just 1.6 volt with up to 32 MIPS at 32 MHz. Memory size range from 16 to 384 KB of Flash and they come in 44- to 100-pin packages. The XMEGA devices are general purpose microcontrollers well suited for a variety of applications including audio systems, ZigBee®, power tools, medical , board controllers, networking, metering, optical transceivers, motor control, white goods and any battery powered product.

  Is there any C or Basic compiler that support the new AVR XMEGA family ?

They aren't in a market yet. Look here:

WinAVR is a suite of executable, open source software development tools for the Atmel AVR series of RISC microprocessors hosted on the Windows platform. It includes the GNU GCC compiler for C and C++.

1.0 What's New
Below is just a sample of what's new.

Added support for these devices: 

ATxmega128A1 

ATxmega64A1 

ATmega32M1 

ATmega32C1 

ATmega32U4 

ATtiny167 

GCC 4.3.0 

New version.There are two new Makefile Templates added. One template will generate a library instead of an application (Makefile.lib) and the other template will enable whole program optimization (Makefile.wpo). 

SRecord 1.38 

New version.SimulAVR 0.1.2.5 

New version.AVR-Ada is temporarily removed from this installation.

Support for Atmel AVR XMEGA
IAR Embedded Workbench V5.1 for AVR now supports the new AVR XMEGA device family from Atmel.

Hi,

  Xmega64A1, Xmega128A1, Xmega256A1

are supported in ICCV7.16 from ImageCraft.

Can some1 upload IAR Embedded Workbench V5.1 (EW-AVR V5.10 full kit)?

thanks,

how can i find which xmega is 8 bit or 16 bit

[Mega32]

how can i find which xmega is 8 bit or 16 bit

How about reading the datasheet , for the desired Xmega MCU ?

But afaik all Xmegas are 8bit , like the "normal" megas.

Which programmer do I need to program XMEGA and UC3 AVR's ?

I didn't find any information on the homepage of ATMEL. If a JTAG ICE-mkII can
handle any of them, that would be very good.

However, the programmer should be cheap, not like the ATMEL products.

Many thanks in advance!

Mega32

in datasheet wrote "High-performance, Low-power 8/16-bit Atmel
® AVR® XMEGA™ Microcontroller "

is there any idea ?

@DarkClover
i use AVRISP mkII to flash XMEGA128A1

@alberto110
"Low-power 8/16-bit AVR"
this is just marketing

like all AVRs (90S, MEGA):
XMEGA has 16bit program bus
XMEGA has 8bit data bus
XMEGA has the same 32 8bit registers

also note - unlike other AVRs :
Instructions in the program memory are executed with a single level pipeline
Write to SRAM takes one cycle and read from SRAM takes two cycles.

XMEGA has powerfull peripherals DMA, EventSystem, QudratureDecoder, InterruptController

[DarkClover]

@xaralampis
OK therefore I can use XMEGA controllers so far. That's very good.

But do you know whether the UC3 controller family can be pogrammed through
the AVRJTAG mkII too?
I found some programmer on the internet but they seem very uncomfortable or
don't have JTAG on board. Do you know some good programmers for the UC3, if
the AVRJTAG mkII doesn't work ?

Thanks...
