Refer to " Operations" for details.
____
1. W / T pin (Only S-1410 Series)

___
when the W / T pin is "L". Switching the mode is prohibited during the operation.
___
The W / T pin is connected to a constant current source (0.3 μA typ.) and is pulled down internally.
___
In addition, the W / T pin has a noise filter. When the power supply voltage is 5.0 V, noise with a minimum pulse
width of 200 ns can be eliminated.
________
2. RST pin (Only S-1411 Series)
This is a reset output pin. It outputs "L" when detecting a low voltage.
_______
Be sure to connect an external pull-up resistor (RextR) to the RST pin in the product without an output pull-up
resistor.
_________
3. WDO pin
3. 1 S-1410 Series
This pin combines the reset output and the watchdog output (time-out detection, double pulse detection).

4. CPOR pin
This is a pin to connect an adjustment capacitor for reset time-out period (CPOR) in order to generate the reset
time-out period (tRST). CPOR is charged and discharged by an internal constant current circuit, and the
charge-discharge duration is tRST
Refer to " Recommended Operation Conditions" and consider variation of CPOR to select an appropriate CPOR
RST is calculated by using the following equation.

5. 1 Cautions on watchdog double pulse detection time
The watchdog double pulse detection time (tWDL) noted in " Electrical Characteristics" is a value with a starting
point at the time when the CWDT pin voltage (VCWDT) begins to rise from the CWDT charge lower limit threshold
(VCWL).
The double pulse detection in window mode is performed even during ΔtWDL shown in Timing Diagram 7-4.
Therefore, if setting to a value with a starting point at the time when VCWDT begins to rise from 0 V, the watchdog
double pulse detection time (tWDL2) is calculated adding ΔtWDL as shown in the following equations.
tWDL2 [ms] = tWDL + ΔtWDL [ms]
ΔtWDL [ms] = CWDT delay coefficient 2 × CWDT [nF] + tWDL0 [ms]

6. WEN pin
This is a pin to switch Enable / Disable of the watchdog timer.
The voltage detection circuit independently operates at all times regardless of the watchdog timer operation.
In addition, the WEN pin has a noise filter. When the power supply voltage is 5.0 V, noise with a minimum pulse
width of 200 ns can be eliminated.
6. 1 S-1410/1411 Series A / B / C / G / H / I type (WEN pin logic active "H" product)
The watchdog timer goes to Enable if the input is "H", and the charge-discharge operation is performed at the
CWDT pin.
The WEN pin is connected to a constant current source (0.3 μA typ.) and is pulled down internally.
6. 2 S-1410/1411 Series D / E / F / J / K / L type (WEN pin logic active "L" product)
The watchdog timer goes to Enable if the input is "L", and the charge-discharge operation is performed at the
CWDT pin.
The WEN pin is not pulled down internally.
7. WDI pin
This is an input pin to receive a signal from the monitored object. By inputting an edge at an appropriate timing, the
WDI pin confirms the normal operation of the monitored object.
The WDI pin is connected to a constant current source (0.3 μA typ.) and is pulled down internally.
If the WEN pin is in Disable after the initialization and reset release are performed subsequent to the power supply
voltage rise, the WDI pin will be able to receive input signals after the WEN pin goes to Enable and then the input
setup time (tiset) elapses.
In addition, the WDI pin has a noise filter. When the power supply voltage is 5.0 V, noise with a minimum pulse
width of 200 ns can be eliminated.

*1. The CPOR pin voltage fall delay time (Δt) is sufficiently small compared to the reset time-out period (tRST).
*2. The time (ΔtRST) the CPOR pin voltage (VCPOR) reaches the CPOR charge lower limit threshold (VCPL) from 0 V is
proportional to the adjustment capacitance for reset time-out period (CPOR). Thus, large CPOR results in large ΔtRST
.

Precautions for Use
A capacitor of 100 pF to 1 μF can be used for the adjustment capacitor for reset time-out period (CPOR) and the
adjustment capacitor for watchdog time-out period (CWDT). Even if the capacitance is within this range, cautions are still
needed when the value is extremely large.
1. Low voltage operation when CPOR is extremely large
When the S-1410/1411 Series detects a low voltage during the CPOR charge-discharge operation, it will take time
for the CPOR discharge operation to be performed if CPOR is extremely large. Therefore, the discharge operation
may not be completed by the time the power supply voltage (VDD) exceeds the release voltage (+VDET). In this
case, since the charge-discharge operation is performed after the discharge operation is completed, a delay time
of the same length as the CPOR discharge operation time occurs by the time the reset time-out period (tRST) count
starts.

2. Relation between CPOR and CWDT
Select a capacitor which satisfies the following expression for CPOR and CWDT. When this condition is not satisfied,
the S-1410/1411 Series may not complete the CWDT discharge operation after a double pulse detection. Unless
the CWDT discharge operation has been completed, the S-1410/1411 Series will not be able to initiate the next
charge-discharge operation even if tRST has elapsed. For this reason, a delay time of the same length as the CWDT
discharge operation time occurs by the time the watchdog time-out period (tWDU) count starts.

3. Re-applying power supply
If the power supply voltage (VDD) falls to 0.9 V or lower, a standby status for 20 μs is required by the time low
voltage detection is released in order for the discharge operation of internal circuit to be performed fully. If an
appropriate amount of time is not secured for the standby status to be completed by the time the power supply is
re-applied, the initialization start will be delayed. For this reason, a delay time of the same length as the time until
the standby status has been completed occurs by the time the tRST count starts after the power supply rises.

________
In the S-1410/1411 Series, when the period of 0.9 V ≤ VDD ≤ −VDET is shorter than 20 μs, the WDO pin and the

RST pin may not output a low voltage detection signal. Even in this case, the S-1410/1411 Series carries out the

Precautions
___
• Since input pins (the WEN pin, the WDI pin and the W / T pin) in the S-1410/1411 Series are CMOS configurations,
make sure that an intermediate potential is not input when the S-1410/1411 Series operates.
________
_______
• Since the WDO pin and the RST pin are affected by external resistance and external capacitance, use the
S-1410/1411 Series after performing thorough evaluation with the actual application.
•
•
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
