Thanks Brian, This one is for a Fujifilm camera, one shutter button, just that, i know which code is using... also have the code for Pentax that should have replaced it, so that part is taken care of... This one i might replace it, all the looking around on the net kept going back to Renesas, some of their 4bit ones, but who knows how old it even was back then when they used it which already has to be more than 6 years ago... have a couple of TI uC somewhere i could use eventually, all the other components and the enclosure and battery are perfectly usable...
