The ADuC7061 is a smaller package (32-lead LFCSP (5 mm × 5 mm)) compared to
48-lead LQFP and 48-lead LFCSP (ADUC7060). Both part numbers have the same
performance as outlined in their common
datasheet. The are differences in the pinout as ADUC7061 has more multifunction
pins in order that the total number of pins can be reduced from 48 to 32 pins.
This is explained in the pin function description section of the datasheet.
