Re: Summary of Power numbers in active mode

Will these numbers find their way into the data sheets?  Other
manufacturers publish the data so that it is easier to estimate power
consumption for various modes of operation.  If it is in the data
sheets, we don't have to bug you in the message groups.   

<R> It is a little difficult to get typical numbers into data sheet
because they are not tested for each device. 

I am more interested in the 22xx, 144 pin parts since I would like to
use the external data bus.  
<R> Power numbers are pretty much identical (less than 1 mA
difference) because the only additional "logic" are port pins and
control pins for the bus. Otherwise same peripherals, same CPU.
  
So far I have not been able to get much dependable info on the
schedule.  My local sales contact is not forthcoming with much info. 
Is there a planned delivery date other than just second half of the
year?  Would it be at all practical for me to plan production in July
or August?  
<R> Well, can't really comment too much on this one. I do know that we
have multiple lots in production flow but I don't know how many orders
are already in the system. By July / August we will have delivered >>
100k pieces, nevertheless, I can't tell you where they go to. There is
one promise though, they will be spread widely.

The other issue I have with these parts is the size.  A 144 QFP is
just too large for this app.  Are any smaller packages planned for the
higher pin count parts?  BGA perhaps?

<R> Plans exist but it is going to be midterm, not within the next 4-6
months.

Regards, Robert
