How to Determine Silicon Version of device?

To determine the silicon version of a particular device refer to the name printed on the chip. The figure below shows a TMS320F2808 device as an example

TMS320F2808GGMA chip identification
CA-26ACRCW lot trace code

The silicon version is given by the second character of the lot trace code. For example:

SECOND LETTER IN PREFIX OF LOT TRACE CODE SILICON REVISION REVISION ID(0X0883) F2801, F2802,F2806 and F2808 COMMENTS
Blank(no second letter in prefix) Indicates Revision 0 0x0000 This silicon revision is available as TMX only.
A Indicates Revision A 0x0001 This silicon revision is available as TMX only.
B Indicates Revision B 0x0002 This silicon revision is available as TMS.
C Indicates Revision C 0x0002 This silicon revision is available as TMS.

For more information on specific device you can refer to respective data sheets. For example for a F280X DSP you can refer to this document (SPRZ171).
