    Hi Thiyagarajan,

    The " B " and " C " in  TMS320C6745BPTP3 and TMS320C6745CPTP3 denotes the device revision codes for the silicon revisions 2.0 and 2.1 respectively.

    As per this document, http://www.ti.com/lit/er/sprz253e/sprz253e.pdf, under section 1.2 , there is a comment " Silicon Revision 2.1 parts that have a minimum operating DVDD (I/O) voltage of 3.0V can be identified by the 3V marking next to the TI logo on the package. please check whether this comment has any co-relation with your problem.

    Refer the above pdf for more details on the usage notes and design exceptions of silicon revisions 2.1.

     

    regards,

    Shankari.
