CY3207ISSP Power Supply

Question: Can CY3207ISSP work with USB Bus power only?

 

Answer:

 CY3207ISSP can be used in following three ways for programming:


1.In System Programming
2.Socket Programming
3.Standalone Programming

In first two programming methods, ISSP programmer connects to PC through USB cable and it gets powered through USB, so it does not require 9V supply.

However, in standalone programming mode, it will not be connected to PC and so it requires 9V supply to get powered.
