This is my post link u gave in renesas
I searched Google upside down day and night and been searching for 2 years.I am not new in this work and I have experience of over 12 years and I want to find a tool that can read and write in this mcu and make changes and I also want to know what family this mcu is from.
This is an 48pins ic and I don't know what company this ic belongs to
If anyone here knows anything about this ic please tell me.
Yes I am sure this is 12850 mcu with 48 pin's.
Yes I have made posts in renesas and couple of other forums too but nothing came in hand.
I would love your help guys
Thank you!

If you have 12 years experience why are you asking for our help?
So you want to reprogram 10 Toyota corolla immobilisers
Maybe you should ask Toyota? perhaps they have a reason to protect the device!
