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
-
