Hi there. I've got a huge box of old mice (approx 150) for parts, and a couple of dozen of the Dell ones have a Cypress Semi CP6238BM mcu on them. I'm trying to find a datasheet for them. Digikey and Mouser both say this is an obsolete / end of life part, Octopart, Ciiva, and AllDatasheets don't have the datasheet and refer me to Mouser or Digikey. Cypress itself does not have the part listed anywhere I can find on their website.
All I want to do is find out what they do and if I can repurpose them. I'm turning to you guys to try to find out. Any help would be greatly appreciated.
