System Reset (with built-in watchdog timer) MM1096
1. RESET
Approximately 1μA (V
CC
=0.8V) of pull up current is output from RESET
2. Capacitor C
T
charging starts when V
CC
rises to V
SH
(MM1096A .= 3.25V, MM1096B .= 4.3V). Output is in
reset state at this time.
3. Output reset is released (RESET
discharge (the time from when C
T
voltage reaches a certain threshold value 1 (.= 1.4V) until C
T
voltage
drops to a certain threshold value 2 (.= 0.2V).
Reset hold time : T
PR
is as follows.
T
PR
(ms) .= 500 C
T
(μF)
C
T
charging starts again after reset release, and watchdog timer operation begins.
Clock input to the CK pin during C
T
charging will cause mis-operation.
4. If a clock is input (negative edge trigger) to the CK pin during C
T
charging, C switches from charging to
discharge.
5. Discharge switches to charging when C
T
voltage drops to a certain threshold value (.= 0.2V). Steps 4 and
5 are repeated while a normal clock is input from the logic system.
6. Output goes to reset state (RESET
threshold value (.= 1.4V).
The formula for C
T
charging time (T
WD
: watchdog timer monitoring time) until reset is output is as follows.
T
WD
(ms) .= 2500 C
T
(μF)
7. Watchdog timer reset time T
WR
is the discharge time until C
T
voltage drops to reset OFF threshold value
(.= 0.2V). The formula is as follows.
T
WR
(ms) .= 100 C
T
(μF)
After reset OFF threshold value is reached, output reset is released and C
T
starts charging. Thereafter,
steps 4 and 5 are repeated if a normal clock is input, and when the clock ceases, 6 and 7 are repeated.
8. Reset is output when V
CC
drops to V
SL
(MM1096A .= 3.2V, MM1096B .= 4.2V). C
T
is charged
simultaneously.
9. C
T
charging starts when V
CC
rises to V
SH
.
When V
CC
drops momentarily, C
T
charging begins after the charge is first discharged, if the time from V
CC
dropping below V
SL
until it rises to V
SH
is longer than the Vcc input pulse width standard value T
PI
.
10.Output reset is released after V
CC
goes above V
SH
and after T
PR
, and the watchdog timer starts. Thereafter,
8~10 are repeated when V
CC
goes below V
SL
.
11.When power is OFF, reset is output if V
CC
goes below V
SL
.
12.When V
CC
drops to 0V, reset output is held until V
CC
reaches 0.8V.
goes low when V
CC
rises to approximately 0.8V.
goes high) after a certain time (T
), from when C
starts charging until
goes low) when the clock ceases and C
T
voltage reaches reset ON
