Grats! Seems like it's customized version. I cannot find ATMEL UC128L5-U anywhere.
UC128L3-U is 64 pin and UC128L4-U is 48 pin UC3L part, so maybe the "5" means a new package (smaller?).
is that the touch controller IC?
Although they do have AVR internally, The touch screen controller would have an mXT... number, surely ?
