Notes:
1. Slew Rate for VCC is 8.75 mV/us and slew rate for VNN is 10 mV/us.
2. Each processor is programmed with a maximum valid voltage identification value (VID), which is set at manufacturing
and cannot be altered. Individual maximum VID values are calibrated during manufacturing such that two processors at
the same frequency may have different settings within the VID range. Typical AVID (voltage identification) range is 0.75–
1.15V for VCC (excluding VCC C6 VID) and 0.75V to 0.9875V for VNN. The VID will change due to temperature changes
and thermal management event in order to reduce the junction temperature of the part.
3. Values are exclusive of +/- 5% tolerances.
4. Battery Mode specification is the minimum voltage needed to maintain clock oscillation. To start clock oscillation, the
device must first boot in normal mode.
