Hi all, I'm trying to identify some of the components in an older mp3 player ... doing a bit of hardware hacking. I'm having real trouble with a couple ICs. I'm wondering if there is a general guide to identifying ICs anywhere. I apologize if this has been answered before, but searched the group and couldn't find anything other than people identifying specific components.
Generally it seems like most ICs have a 2-3 line label such as (actual example from 64 Mb DRAM):
SAMSUNG 543 K45641632H-TC7556416 ZHI115DCC
My naive approach is to go to alldatasheet.com and simply plug in anything that looks to be a model number until I find a datasheet that matches or is plausibly similar. However I know that there are some "discontiguous" model number correlations, e.g. the 74x components, a74LVC04 has the same basic function as a 74HC04.
Can anyone give me any advice for reading and understanding IC model numbers? I'll post the specific IC info if anyone wants to give me hints, but I was hoping for some general info as well. Thanks in advance!
