REVID: Some TMX Revision A Devices Have an Incorrect REVID Value

Revision Affected

A

Details

Some early TMX Revision A devices have an incorrect value in REVID (address 0x0005_D00C). The REVID incorrectly indicates the Revision 0 value (0x0000_0000) instead of the correct Revision A value (0x0000_0001). Software that uses REVID to distinguish between Revision 0 and Revision A will not function as intended. There are no other functional impacts due to this erratum. Applications that do not use REVID in software will work properly as any other Revision A device.

Lot Trace Code affected:

  • 65AVVDW
  • 66ALSXW

Workaround

The device markings on the package are correct and can be used to identify the device revision.
