 Bigger Bigger  Smaller Smaller  Reset Reset

guys, I bought the starter kit and am checking it out. One thing which seems odd is that the schematcs (as published at http://arduino.cc/en/uploads/Main/Arduino_Uno_Rev3-schematic.pdf) show two processors - ATMEGA16U2 and ATMEGA328P.

The actual hardware as arrived (and as shown on the site: http://arduino.cc/en/uploads/Main/ArduinoUno_R3_Front.jpg ) has just one chip - the 328P.

Does any one know what's the deal here, where can one get the actual schematics?

TIA,
rr

See that square chip just north of the 16 MHz crystal can?  Read the part number on that.
