Introduction

In-circuit programming is convenient for prototyping, manufacturing, and in-system field updates. CY8C20xx6A devices can be programmed in-system using the in-system serial programming (ISSP) protocol, a proprietary protocol used by Cypress. This reference manual provides necessary information to enable developers and programmer vendors to create their own in-system programming solutions for the CY8C20xx6A device.

This reference manual provides the information developers and programmer vendors need to create their own in-system programming solutions for CY8C20045, CY8C20055, CY8C20xx6A, and CY8C20xx7 devices. The following topics are covered in this document:

  • Information on how to interface a host programmer with CY8C20045, CY8C20055, CY8C20xx6A, and CY8C20xx7 devices
  • Description of the ISSP protocol
  • AC/DC programming specifications
  • Programming vectors
  • Introduction to the Intel hex file format
