Isn't "AT91SAM4L-EK" the part number of the evaluation klt? Do you know how the controller is actually labelled?

Yeah, that's just the designation to use for SAM-BA, the chip is actually a ATSAM4LC2CA

looking at the back of the calculator:

1 - reset button (connect to ground)
2 - ground
3 - erase button (connect to pin 4)
4 - erase button (connect to pin 3)
5 - USB green wire (data -)
6 - USB white wire (data +)

note that +5 volt from USB is not connected.

I don't know if the MPN has changed. The version with the SAM4L chip was likely released sometime earlier this year, maybe in the March/April time frame. Firmware has changed, of course, to support the new chip.
