IC identification (2130MBX A)hall effect sensor eeprom

Hello I am trying to find out how to read the eeprom data from a Hall effect sensor inside a Ferrari Getrag transmission.
They don’t make them anymore and it’s not like a Ford you can just find a used transmission from and harvest parts from.

I am an automotive locksmith in Northern California and I get asked to do some interesting things but cloning a Hall effect sensor takes the cake. I have a few different eeprom readers but until I know how/ what to identify as the manufacturer and chip type I cannot just copy the data. I need a datasheet to help identify my target.
Doing a lot of research on here and the interwebs has yielded no results.
I do know I might need a more specialized reader if the target isn’t what I call a normal eeprom, seems like some of these might send out a different voltage signal for the data output and not a binary file like the other eeproms i work with. That won’t be an issue IF I can figure out what the heck to read this as.
Thank you!

Hello,

I could not verify this part number.

I am not aware of any way to read this.

Hi thomas_redwoodlock,

Unfortunately, that’s most likely a microcontroller rather than just an EEPROM, with proprietary markings to obscure it’s identity. Assuming so, they probably set the read-protect bits while programming, making it all but impossible to read out its embedded code without very specialized expertise and equipment.

Hi @thomas_redwoodlock ,
There’s thin chance that this is a TI’s MPS430FR21xx series MCU.

You could try to hook it to a MPS430 programmer to see if the chip is recognized via JTAG or SBW.

As anticipated by @David_1528 above, most likely the chip’s firmware is protected, thus you won’t be able to copy it.

As a Ferrari part, the chip is probably overclocked for maximum performance.

Cheers, heke

Hi, thomas_redwoodlock!
I assume that you can’t do anything with this chip.
And I agree with David_1528.
This is a custom chip and you won’t find any information on the Internet. Unfortunately.
Unless you buy it in an online store.

I appreciate all the feedback and ideas y’all. I will do a little more research and see if the customer is okay with me going deeper and buying a reader i will never use for “normal” locksmith work lol.
If i get anywhere i will be sure to let you know!
