Notes:
*
1 Monitoring time is the time from the last pulse (negative edge) of the timer clear clock pulse until reset
pulse output. In other words, reset output is output if a clock pulse is not input during this time.
*
2 Reset time means reset pulse width. However, this does not apply to power ON reset.
*
3 Reset hold time is the time from when V
CC
exceeds detection voltage (V
SHR
) during power ON reset until
reset release (RESET
*
4 Watchdog timer monitoring time (T
WD
), watchdog timer reset time (T
WR
) and reset hold time (T
PR
) during
power supply rise can be changed by varying C
T
capacitance. The times are expressed by the following
formulae.
Example : when C

5 The voltage range when measuring output rise and fall time is 10~90%.
*
6 The IC can be made to operate only as a reset IC with delay during Vcc rise by connecting the RCT pin to
GND.
*
7 V

rise time should be 100μS or more, and fall time should be 50μS or more.
