What's this please? (Component Advice)

Also... stereo or mono?

Hello I Hope you all will be fine.
S i have an EEPROM for which i cant find the right datasheet. i do know that it is microchip eeprom and is atleast 7 or 8 years old.(Plz See Pic). The Marking is ATMLH150

Main problem is i want to read the chip but until i know the right name for it i cannot be shure that i am reading the right chip or not..
So please help..

mariush:
Well, it's an eeprom chip.  It was made by Atmel which is now part of Microchip

The ## part tells the truncation code (a sort of unique ID)

Example from AT24MAC402 (2 kbit eprom with i2c) datasheet

ATMLHYWW
## M @
AAAAAAAA

AT24MAC402 Truncation Code ##: P4
AT24MAC602 Truncation Code ##: P6

Date Codes
Y = Year 
2: 2012 6: 2016
3: 2013 7: 2017
4: 2014 8: 2018
5: 2015 9: 2019

M = Month
A: January
B: February

L: December

WW = Work Week of Assembly
01: Week 1
02: Week 2

52: Week 52

##  truncated part code

M: 1.7V min

@ : country where it's made

AAAA  =

and so on .....


So yours is ATMLH , maybe from 2011, week 50

2F or 2FB would be the truncation code

later edit:

In this post here : https://www.eevblog.com/forum/programming/atmlu-eeproms-marked-atmlu-identification/

There's 2FB listed as AT24C512B (512K as 65,536 x 8) : http://ww1.microchip.com/downloads/en/devicedoc/doc5297.pdf

It's obsolete, replaced by AT24C512C

fkfaraz:
Thank You @Mariush for the great response. Honestly i did not thought someone will reply here. so thanks for that

the complete no is
ATMLH150
2FB 2
@1H0064a

A local shop is quoting 24c02 for its replacement. is it right part for this???

mariush:
Well, it would probably be pin compatible, but the amount of bytes of eeprom memory would be different. 

If the original has 512 Kbit of data ( AT24C512B, 65536 x 8 bits )  you could replace with a 24C02 with only 2 Kbit of memory but if something tries to read or write data from above that 2 Kbit threshold, everything's gonna go bad, because there's no memory there.

Ideally you would get a programmer to read the chip contents and see how much data actually is stored in the chip, then get an eeprom with suitable size and same pinout.
