Table 16.6 Power-on Reset Circuit Electrical Characteristics
Symbol
Power-on reset start time
Power-on reset cancel operation start voltage
Hardware reset
Supply start up condition when using power-on reset circuit
Note
1: The measuring condition is Vcc=AVcc=5.0 V and Topr=25 °C.
2: Keep Vcc<0.5V for over regulated time to execute the reset operation.
Table 16.7 High-speed Ring Oscillator Circuit Electrical Characteristics
Symbol
Settable high-speed ring oscillator minimum period
High-speed ring oscillator adjusted unit
Note
1: The measuring condition is Vcc=AVcc=5.0 V and Topr=25 °C.
Table 16.8 Power Circuit Timing Characteristics
Symbol
td(P-R)
Time for internal power supply stabilization during powering-on
td(R-S)
STOP release time
Note
1: The measuring condition is Vcc=AVcc=2.7 to 5.0 V and Topr=25 °C.
2: This shows the wait time untill the internal power supply generating circuit is stabilized during power-on.
3: This shows the time till BCLK starts from the interrupt acknowledgement to cancel stop mode.
