xmega project

The new AVR XMEGA family from Atmel 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

All XMEGA A devices run from 1.6 to 3.6 volt and up to 32 MHz and include:
- 32 MIPS at 32 MHz
- 4 DMA channels
- 8 Event System channels
- Crypto engine for AES and DES
- Real-Time Clock
- Brown-out Detector
- Watch-dog Timer
- Internal RC

I want to start using XMEGA series
which one of e-books will suggest me
 

Ignore xmega and start with new LPC1100 and LPC1300 series from NXP.I think 32 bit cortex M3 and M0 is better.
 

Cortex 3, I think so it's 32bit core
SAM7,SAM9 and AVR32 are more powerful

but I need ultra low power consumption micro controller for portable uses

I can just find SAM7L series as 32bit low power consumption MCUs
SAM7L consuming more energy and haven't any benefit of ARM series
 

new LPC1000 series of philips liks as LPC1100 are very low power ,under 200uA/MHz!!!!

Click to expand...

200uA! Nice
In Active mode or Idle mode ?
I think XMEGA at least use 350uA in 1MHz in 1.8v and 135uA in same condition in Idle mode

AT91SAML7 use double

Could Help me to find power consumption of LPC1100 series I cantn't find it's power consumption details.
SPI in this series transmit also in 16bit mode?

http://www.electronicsweekly.com/Ar...s-multicore-arm-cortex-m0-microcontroller.htm

in article :
LPC1100 is an MCU with a power/performance of under 150µA/MHz.

In comparison the Cortex-M3 based LPC1300 consumes approximately 200µA per MHz.

“We are working on getting M0 under 150µA/MHz, the target in the short term is 100µA/MHz and I believe 50µA/MHz is achievable in the longer term.
