APPENDIX B:
The following table and package marking information
illustrates how to determine the revision of the
MCP2140 device. The revision information can be
determined by the Year and Week Code of the
manufacture, printed on the device as shown in
Table B-1. The revision information is also available via
the IrDA standard device ID.

determine the device revision is with the
device ID that the device transmits during
the NDM/Discover modes of the connec-
tion sequence. A PC with an IR port will
display this information when the mouse
cursor is placed over the IR icon in the
system tray.
