    Help Reprogramming Legacy PSoC via ISSP (CY8C26443)

    user_24078653

      Is there any way available commercially to reprogram the CY8C26443 in-situ using the ISSP protocol? Our product is expected to have a lifetime of 20+ years and we regularly receive them back from the field for recalibration, expecting to be able to upgrade their firmware to enhance reliability etc. However, it appears that Cypress does not sell a product that will do this. I have previously asked this question to Cypress both directly and via one of my suppliers' FAAs and have been told that Cypress could not suggest a solution.

         

      The Miniprogs have never supported this chip family, even though it uses the ISSP protocol. Our old ISSP box will program them, but there's no up-to-date PC software for it and newer versions of Windows have some sort of problem with the USB the Cypress ISSP software.

         

      Any advice much appreciated
