Where this Data Sheet is denoted as “Advanced” or “Preliminary”, devices will be either Engineering or Prototype
Samples. Devices of this status have an R suffix after the software ROM identifier, for example JN5139-Z01 R .
Devices may also have an additional digit immediately after the R suffix, for example R 1 , R 2 , R 3 etc. This additional
digit is use to identify different revisions of engineering or prototype silicon during these product phases.
