VVCC_BOR– | Brownout power-down level(1) | | dDVCC/dt | < 3 V/s | 0.7 | 1.66 | V |
VVCC_BOR+ | Brownout power-up level(1) | | dDVCC/dt | < 3 V/s(2) | 0.79 | 1.68 | V |
(1) Fast supply voltage changes can trigger a BOR reset even within the recommended supply voltage range. To avoid unwanted BOR resets, the supply voltage must change by less than 0.05 V per microsecond (±0.05 V/µs). Following the recommendation for capacitor CDVCC should limit the slopes accordingly.
(2) The brownout levels are measured with a slowly changing supply.
