Determining chip revision

Version 1
    Question: How can I determine the revision of the AN21xx EZ-USB chip that I have?



    The stencil on the part can identify the chip revision, for example:

        ENY0876    KOREA

    The leading E in the last line indicates a revision E part in this example.

    You can also use the EZ-USB Control Panel to determine chip rev by pressing the Get Dev button. The bcdDevice field displays the chip rev as follows:

    0x4 = Rev E, 0x3 = Rev D, etc..
