Hi,
‘67023561’ does not seem to be a valid part number from the current NXP portfolio, I wasn’t able to find it in the internal system. It is possible an archived device from the Philips portfolio which does not seem to be manufactured by NXP any more.
I did find any documents in the internal database regarding this part number.
I apologize for the problems this may cause.
Regards,
Jose
