re: Atmel announces new SAM D20 series of ARM Cortex-M0+ MCUs

The question for me who is better? Full comparison need to be run, and see where each of them have better and not performance. Everyone try to sell but without highlight the pros comparing to the available product on the market is not mean to much for me. It is mean spending of time to compare one new thing. While if the company want to really attract me fast they should directly point where are 100% better there there and there.

Energy Micro has had those features on Cortex-M devices for years..

Until Atmel embrace the idea of overlapping the AVR family, smaller and probably more useful/popular Cortex-M0 will be slow to appear. Atmel - please prove me wrong!

I really like the way that Atmel have merged the best features from the AVR and ARM families to generate this new offering. Of course they already have MCUs based on Cortex-M3 and -M4 processors (and higher), but these new Cortex-M0+ parts fill a real need with regard to miniscule power consumption required by the Internet of Things. I particularly like their Event system, which allows peripheral to do things autonomously without waking the MCU unless it's necessary -- such as an A/D converter that periodically takes a reading but only wakes the MCU if the value falls inside (or outside) specified bounds...

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
