Question
What are the differences between a Rev. D/E Coldfire interface cable and a Rev. F Coldfire interface cable?
 
Answer
The main physical change between the Rev. D/E and Rev. F is that Rev. D/E has a male connector which connects to the target via a ribbon cable. The Rev. F cable has a female connector which plugs directly into the target. This was done to reduce EMI in order to pass CE certification. PEmicro has a male-to-female ribbon cables available for use with the Rev. F cables (part number CAB_RIBBONCF).

Electrically there are several differences. The Rev. D/E cable derives power from pin 25 whereas the Rev. F cable derives power from pin 9. Additionally, the Rev. D/E cable has an internal pull-up on the TEA signal which does not exist on the Rev. F cable. The user should make sure they have some sort of pull-up of the TEA signal.
