Cypress does not provide test sockets. Since this product is EOL, Cypress does not have any kits which can serve the same purpose. We extremely sorry for the inconvenience.
Do you know where I could buy the socket?
Do you know the PN of the socket (to program cy37512P208-100UMB?
I am not able to provide you the part number for the socket (since the kit is obsolete long ago). But you can try for sockets in Digikey, Mouser and other distributors.
