Hello

no, unfortunately, the bonding lands are different.

About half of the supply pins are at the same location, the others are 
shifted or mixed ....
Concerning the clock, there are 3 clocks instead of 2 in the 8700. Also 
the pins of the clocks have all moved a lot.

8700 : 32kHz XTAL (system clock after 2 PLLs) + 24 MHz XTAL (USB clock)
8701 : 32kHz input (probably an XTAL connection possibility also) + 24 
MHz XTAL + 1.something MHz XTAL

my conclusion : the device architecture has been changed.
I suppose the wakeup time of the PLL was probaly too low with a 32kHz 
quartz, or something similar...
