Am I the only one who was pleased by the June Atmel Product ENews, introducing Atmega644 ? :D

Quote:
ATmega644 is device pin and functionally compatible to ATmega32, with higher memory density and the capability of low operating range down to 1.8V and up to 5V for maximum 20 MHz performance. It is available in 40-pin PDIP and 44-pin/pad TQFP and QFN/MLF packages.

It is on the roadmap presented at the recent seminars--part of the 164/324/644 family. My note on the page indicates that they will be automotive temperature range; AFAIK this is the first extended-temperature range AVR?

Don't hold your breath waiting for samples. The '644 is indicated to sample Q405, with the others in Q106.

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

Any idea when avr-gcc will support this device? For now, it seems that only assembly language is supported.

When a volunteer has time to add it in....

So anyone seen that AVR yet ? I was browsing the table looking for something as cool as the m168, but bigger :D
"Just the step up" and the 644 seems to be just the same new generation device.. All the new power saving features, pin interupts, and a tiny package....

Hi buserror, I've built a few projects with the 644. They're widely available on digikey.com

Hi Kevin; yeah I realized that afterward I was replying to message from July.... 05 (!)

Are you happy with the 644 ? I must say I'm quite fond of the 168, I just wish it had more sram :D
Since I'm new at AVRs, I'm just ignoring the 'older' generation and picking only the most recent parts...

Yeah, I thought the dates were a bit unusual :wink: I like the 168, too. I've been very pleased with the 644 (and 324), especially compared to the older Mega16 and Mega32. I do a lot of battery designs, so I extensively use the picopower and pin change interrupts with these newer MCUs.

check out the picopower series, the mega328P, seems to be pin compatible with the 168, 2K RAM, 1K EEPROM, and 32K flash. Prices might be reasonable, and might be available now or real soon now....

It'll answer several potential problems I have with an SD card reader using the Mega168.

Thanks for the tip, Nightsky. I found the press release ( http://www.atmel.com/dyn/corpora... ). Sounds like they'll be useful MCUs when they hit the street.
