Pin Functions
Refer to " Operations" for details.
1. W
____
/ T pin (S-1410 Series only)
This is a pin to switch the watchdog mode.
The S-1410 Series changes to the time-out mode when the W
___
/ T pin is "H", and changes to the window mode
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.
1. 1 Time-out mode (W
___
/ T pin = "H")
The S-1410 Series detects an abnormality when not inputting an edge to the WDI pin during the watchdog time-out
period (tWDU). And then "L" is output from the WDO

4. CPOR pin
This is a pin to connect an adjustment capacitor for reset output delay time (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.
tRST is calculated by using the following equation. Take into consideration CPOR variation.
tRST = 6,500,000 × CPOR [F] + 0.0002
5. CWDT pin
This is a pin to connect an adjustment capacitor for watchdog output delay time (CWDT) in order to generate the
watchdog time-out period (tWDU) and the watchdog double pulse detection time (tWDL). CWDT is charged and
discharged by an internal constant current circuit.
tWDU is calculated by using the following equation. Take into consideration CWDT variation.
tWDU = 50,000,000 × CWDT [F] + 0.0011
Moreover, tWDL is calculated by using the following equation.
tWDL = tWDU

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.
6. 1 S-1410/1411 Series A / B / C / G / H / I type (WEN pin logic active "H" product)
The watchdog timer becomes 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 becomes 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.

2. From reset release to initiation of charge-discharge operation to CWDT pin
The charge-discharge operation to the CWDT pin differs depending on the status of the WEN pin at the reset release.
2. 1 When WEN pin is "H" at reset release (Active "H")
Since the watchdog timer is Enable, the S-1410/1411 Series initiates the charge-discharge operation to the CWDT
pin.

Since the watchdog timer is Disable after the CPOR pin performs the charge-discharge operation 4 times, the
S-1410/1411 Series does not initiate the charge-discharge operation to the CWDT pin. If the input to the WEN pin
changes to "H" in this status, the S-1410/1411 Series initiates the charge-discharge operation to the CWDT pin.

When the WDI pin detects an edge during the charge-discharge operation to the CWDT pin, the internal counter
which counts the number of times of the charge-discharge operation is reset. The CWDT pin initiates the discharge
operation when an edge is detected, and initiates the charge-discharge operation again after the discharge operation
is completed.

Precautions
It will take time for the discharge operation to be performed if the capacitance of CPOR is extremely large at the low
voltage detection, so the discharge operation may not be completed by the time the power supply voltage exceeds
the detection voltage. In that case, since the charge-discharge operation of the CPOR pin is performed after the
discharge operation is completed, the delay time of the same time length as the discharge operation occurs in reset
time-out period (tRST).
Select a capacitor which satisfies the following equation for CPOR and CWDT. If this condition is not satisfied, the
delay time of the same time length as the discharge operation occurs in tRST since the discharge operation of an
external capacitor connected to the CWDT pin is not completed by the time the CWDT pin initiates the next
charge-discharge operation.
CWDT / CPOR 600
When the power supply voltage falls to 0.9 V or lower, set a time interval of 20 μs or longer by the time the power
supply is raised again. If the appropriate time length is not secured, the time-out period after raising the power
supply voltage may get delayed.
When the time that the power supply voltage falls below the detection voltage is short, the S-1410/1411 Series may
not detect a voltage. In that case, the time-out period after raising the power supply voltage may get delayed.
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.
