Brown-Out Detection
Enhanced Power-On Reset
This implementation of power-on reset exists in newer versions of ATtiny25/45/85. The table
below describes the characteristics of this power-on reset and it is valid for the following devices,
only:
Table 21-6.
Note:
Table 21-7.
Note:
• ATtiny25, revision E, and newer
• ATtiny45, revision G, and newer
• ATtiny85, revision C, and newer
