I'm looking for the datasheet for what appears to be a serial EEPROM, part number "481K", probably made by S-MOS, now Seiko Epson.
See location IC501 at the top RHS of this photo:
It is the main PCB in an LG GDR-8163B DVD ROM drive.
The EEPROM (?) appears to have been manufactured during week 22 of
2004.-- Franc Zabkar
