Device speed grade
- 4 years ago
Nope, not available. The JTAG ID encodes the specific device family and size (number of cells), and number of I/Os (package type, sometimes). Speed grade and temperature grade are not encoded. They are determined after the die is packaged and tested.
You could do that yourself if you wanted to add specific registers for your application that encode such info, but it will not be available on unprogrammed parts direct from the factory.
