From http://www.mcumall.com/forum/topic.asp?TOPIC_ID=3024 - Identifying old ATML prefixed chips: ATMLxxxx's are ATMEL EEPROMs. The second line, 3 character code, is the truncated part number.

As etched on IC:

ATMLHyww
02B 1
nnnnnnnn

y = Year
ww = Week
02B = Device
1 = Voltage Indicator
nnnnnnnn Lot number

Add the Atmel prefix “AT24C” (EEPROM Part Prefix) to the Device code (02B) to get the complete part number.
