Power-on Reset for the
ATtiny12

ATtiny11/12
A Power-on Reset (POR) pulse is generated by an on-chip detection circuit. The detec-
tion level is nominally 1.4V. The POR is activated whenever V
level. The POR circuit can be used to trigger the start-up reset, as well as detect a fail-
ure in supply voltage.
The Power-on Reset (POR) circuit ensures that the device is reset from power-on.
Reaching the Power-on Reset threshold voltage invokes a delay counter, which deter-
mines the delay for which the device is kept in Reset after V
of the delay counter can be defined by the user through the CKSEL fuses. The different
selections for the delay period are presented in Table 10. The Reset signal is activated
again, without any delay, when the V
If the built-in start-up delay is sufficient, RESET can be connected to V
