1. These POR trip points are only provided for guidance. Device operation is only characterized for power supply voltages specified under rec-
ommended operating conditions.
2. For devices without voltage regulators V_CCINT is the same as the V_CC supply voltage. For devices with voltage regulators, V_CCINT is regu-
lated from the V_CC supply voltage.
3. Note that V_PORUP (min.) and V_PORDNBG (max.) are in different process corners. For any given process corner V_PORDNBG (max.) is always
12.0mV below V_PORUP (min.).
4. V_PORUPEXT is for HC devices only. In these devices a separate POR circuit monitors the external V_CC power supply.

1. Insensitive to sequence of V_CC and V_CCIO. However, assumes monotonic rise/fall rates for V_CC and V_CCIO.
2. 0 < V_CC < V_CC (MAX), 0 < V_CCIO < V_CCIO (MAX).
3. I_DK is additive to I_PU, I_PD or I_BH.
