Request datasheet for pcf7947at chip

Hi. I have a Renault key kard that uses pcf7947at chip as complete solution for immobilizer and RFID, now I have problem for just unlocking the door, the rest buttons and functions work perfectly.
I have tested all traces and components because I do repairs for many years. Can anyone provide me complete datasheet for that chip?
Description goes long sorry.

now classified as obsolete on many part providers, since it deals with some car security, finding the datasheet may prove difficult, tried on many sites no avail
many dumb links, many redirections for the pdf ...
