Table 3-4 • Overshoot and Undershoot Limits
3 - 4
Pads
AV, AC
AT
VCCI
Notes:
1. Based on reliability requirements at a junction temperature of 85°C.
2. The duration is allowed at one cycle out of six clock cycle. If the overshoot/undershoot occurs at one out of two cycles,
2.7 V or less
3.0 V
3.3 V
3.6 V
the maximum overshoot/undershoot has to be reduced by 0.15 V.
