A question to @form:

Data sheet of A3255Q48 does not show pin-assignments (DVDDx...)  See picture on page 12 (of 15) in the mentioned pdf-file above.

However, data sheet of A3256Q48 (the 110nm-chip) shows the pin-assignments clearly (DVDD1... 40 etc.)

Is there a possibility to find out a data sheet (or any proper drawing) showing the complete assignment-list?

thanks, fly

Pin assigment is on pages 10, 11 and 12. Are you blind? :)
