Hello all Is there anyone who can suggest where to get some info on the IC. I can not find it on

The joystick is a Logitech extreme 3d, with plenty of buttons. Did have it to pieces, because the reaction time of the X and Y axis are very slow. The plug is for a normal joystick port, have also a adapter for use on a USB port. The IC inside is made by ST, did forget to count the amount of pins, might be around 20 DIL. The markings are:

It's probably a mask programmed microcontroller, possibly 8-bit.

Thank you very much for the few answers I did get. As far as I remember when the joystick was open there was no crystal on the board. Did download the ST72632 CPU but it is the wrong one. Could not answer faster, because of problems with my W98se C-drive, only my W XP on the D-drive was working. Seems I am getting old for not getting the answers in Google. Thanks again Bert.
