3.3V Neuron backward compatible with existing COMM Tranceivers

Question: Will the 3.3V Neuron work with Echelon's Transceivers?



Yes. The 3.3V Neuron has a 3.3V and 5V compatible COMM port to enable backward compatibility to existing 5V COMM transceivers. In order to make the 3.3V Neuron COMM port 5V compatible, pin CVDD has to be supplied with 5V supply. Also, as specified in the datasheet, the 5V supply should only be applied after the chips' 3.3V supply has stabilized.
