Electrical Specifications
2.4.1 Maximum Ratings
Table 2-12 contains the processor stress ratings. Functional operation at the absolute
maximum and minimum is neither implied nor guaranteed. The processor should not
receive a clock while subjected to these conditions. Functional operating conditions are
given in the DC tables. Extended exposure to the maximum ratings may affect device
reliability. Furthermore, although the processor contains protective circuitry to resist
damage from static electric discharge, one should always take precautions to avoid
static voltages or electric fields.
