Like the classic controller, the joystick potentiometers appear to be wired in parallel. The accelerometer chip is in the LIS3L02 series from [http://www.st.com STMicroelectronics]. The AE variant is not on their web site; their closest public product is their [http://www.st.com/stonline/stappl/productcatalog/app?path=/comp/stcom/PcStComOPNTableView.onTheClickOfOPNLink&code=88227&producttype=product LIS3L02AT], in the same LGA-8 package, but possibly with a different pinout.

+The microcontroller chip appears to be a relabeled NEC (now [http://www2.renesas.com/micro/en/product/index.html Renesas]) uDP78F05 microcontroller, or a pin-compatible equivalent.
