Sep 2004 3.1 • Added references to the MDI/MDI-X feature. • Added lead-free information. • Removed EEPROM Map bit descriptions. These descriptions can now be found in the 82551QM/ER/IT EEPROM Map and Programming Information. • Added 82551IT Test Port Functionality (Chapter 10). • Added new values for RBIAS100 and RBIAS10. RBIAS100 = 649 and RBIAS10 = 619 . • Removed all references to the 82551ER and 82551QM controllers. 82551ER and 82551QM information can now be found in their respective datasheets. Nov 2004 3.2 • Updated the section describing “Multiple Priority Transmit Queues”. • Updated the section describing “VLAN Support”. • Added information about migrating from a 2-layer 0.36 mm wide-trace substrate to a 2-layer 0.32 mm wide-trace substrate. Refer to the section on Package and Pin- out Information. • Added statement that no changes to existing soldering processes are needed for the 2-layer 0.32 mm wide-trace substrate change in the section describing “Pack- age Information”. Jan 2005 3.3 • Added a note for PHY signals RBIAS100 and RBIAS10 to Table 8. April 2005 3.4 • Corrected the note in section 11stating that the maximum rating for the Case Tem- perature under Stress for the 82551QM/ER is 70° C instead of 85° C.
