UC3B0256 QFN-64 package thermal pad size !!!
i got reply from ATMEL that the thermal pad is 6*6mm: Here is the right size of thermal pad : D2 min = E2 min = 5.9 mm D2 typ = E2 typ = 6.0 mm D2 max = E2 max = 6.1 mm

is external pull-up ready needed for push button?
i got this from ATMEL for UC3B: the pull-up value : Typ: 19k Max: 25k Min: 13k

is external pull-up ready needed for push button?
yes, i understand this, my main consideration is the extra power consumption these resistors introduced in my low power design.

what's the current sink capability of UC3B pins?
yes, i got reply from ATMEL that the sink capability is the same as sourcing. And they pointed out some errors at datasheet Rev.G http://support.atmel.no/bin/cust...

UC3B0256 QFN-64 package thermal pad size !!!
if it's the same for everyone, then why the variance on UC3B's datasheet can be this big?

UC3B0256 QFN-64 package thermal pad size !!!
but i don't think all the QFN packages got the same pad size.

urgent question about Main OSC of UC3B and crystal !!!!
I got reply from ATMEL that I can skip external capacitors, and the crystal can be started by internal ones.

the best unipolar single ended to differential circuit
that ADC is true differential, so it's +input plus -input / 2 should always be Vref/2.

the best unipolar single ended to differential circuit
yes, i think i will change a ADC to single ended. Thanks.

the best unipolar single ended to differential circuit
hi, The reason that I need to convert is is that my ADC is full differential input, and it's a really good low power ADC. so I have to convert single ended to differential. My...

does RCAUSE reset itself after read?
ok, thanks.
