Hello, I've sampled some 18F458's from MC, but received the Extended Temperature version (E/P) instead of the normal Industrial (I/P). According to Fig. 27-1 and 27-2 in the datasheet, the E/P part is limited to 25Mhz where the I/P part runs up to 40Mhz. Question: Is it safe to assume that running the E/P part at 40Mhz is ok as long as the temperature-range of the I/P part is obeyed? Thanks!
