Trying to find details about this chip. New to this and trying to follow tips to fix a car. This chip i was told was going to be a 93xxx series eeprom but as you can see its not. I cant find anything on it looking up the part number unless im missing something. I need to read the code and change a serial number on it. I understand the process for the 93xxx eeproms to read and write on it but without any info on this one I'm not sure if its even a eeprom or if I'm wasting my time. Any tips would be appreciated.

You're focusing on the wrong half of the number. Parts look to available, so focus on how the circuit connects to the various pins and what it does and the context.

Why do you think this part needs replacing? 

It's perhaps a custom part for a specific application?

Trying to bypass security system on my car. Chip is out of ecm and I can’t find diagram for it and the whole board is covered with an inch of silicone that’s brown. From the very little I found I need to wipe this eeprom or install a new one with only the vin on a specific line. Was told 95xxx series eeprom that I know how to write but with no details of one in picture I can’t set program correctly to do it. Guessing best bet is to find compatible one and write and install it instead.

@karl2 I am quite sure that you will not get a satisfactory answer to your question, because such moulded systems are usually customised components in the automotive industry. Only the car manufacturer in question will be able to answer this, but it is more likely that you will have a lawsuit on your hands.
