The table below documents when MLAN commands  have been added to the MLAN software.  The chip version number can be found on the MLAN chip within the controller.

In most cases with the introduction of new commands to the software in MLAN chips, 12 software chips were either first to be updated or both the 12 software and the 4 software chips were updated at the same time.  Not all chips are listed below.  What is listed are chips that marked a change in the software and were available for testing.  If your chip is not listed, it may indicate that your chip did not mark a change in the software or possibly it was available for testing when this data was compiled.  Chips versions numbers indicate a date.  For instance chip "60603A" means 1996 (6), June (06), 3rd (03) followed by "T" for twelve software or "A" for four software.  Your chip version number may fall somewhere in between the chips listed below if it is not directly listed.

Other Notes:

• Controllers using chips prior to 60603A (06/03/1996) have an earlier circuit board which would need replacement if the chip is to be updated.
     
• Chips after 90317A (03/17/1999) will have all parameters available. 
     

Chips prior to 90317A (03/17/1999), please see chart below.
