CONVENIENCE TIMER
Rev.1.4_00
© SII Semiconductor Corporation, 2014-2016
The convenience timer is a CMOS timer IC which operates with low current consumption, and is suitable for the time
management of the relative time.
The S-35710 Series compares the timer value and the value written to the internal register, and outputs an interrupt signal
when the values match each other.
The timer is a 24-bit binary-up counter.
The internal register data can be set freely by users via a 2-wire serial interface. Consequently, the time before the occurrence
of an interrupt signal can be set freely.
Caution
This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to SII Semiconductor Corporation is indispensable.

INT Pin Interrupt Signal Output
The INT pin interrupt signal output (time-out type) can be selected from either of the following:
• One-shot loop time-out
• Handshake time-out
1. One-shot loop time-out
One-shot _______
loop time-out is a type to output "L" pulse interrupt signal repeatedly from the INT pin.
After the RST pin changes from "L" to "H", the timer starts the operation. Then, the INT pin outputs "L" pulse when
the timer value matches the value written to the wake-up time register. After that, the S-35710 Series resets the timer
automatically, and restarts a count-up action.
Remark
1. 1
The above description is the example of Nch open-drain output product.
In CMOS output product, the INT pin output is the inverse logic of Nch open-drain output product.
Write mode
If write operation is performed to the wake-up time register during the count-up action, the action will be restarted
after resetting the timer.
This operation is called "write mode".
_______
If "L" is input to the RST pin before the timer value matches the value written to the wake-up time register, the timer
and the wake-up time register are reset.

Serial Interface
The S-35710 Series transmits and receives various commands via I2C-bus serial interface to read / write data.
1.
Start condition
When SDA changes from "H" to "L" with SCL at "H", the S-35710 Series recognizes start condition and the access
operation is started.
2.
Stop condition
When SDA changes from "L" to "H" with SCL at "H", the S-35710 Series recognizes stop condition and the access
operation is completed. The S-35710 Series enters standby mode, consequently.

3. Data transmission and acknowledge
The data transmission is performed at every 1 byte after the start condition detection. Pay attention to the specification
of tSU.DAT and tHD.DAT when changing SDA, and perform the operation when SCL is "L". If SDA changes when SCL is
"H", the start / stop condition is recognized even during the data transmission, and the access operation will be
interrupted.
Whenever a 1-byte data is received during data transimmion, the receiving device returns an acknowledge. For
example, as shown in Figure 25, assume that the S-35710 Series is a receiving device, and the master device is a
transmitting device. If the clock pulse at the 8th bit falls, the master device releases SDA. Consequently, the S-35710
Series, as an acknowledge, sets SDA to "L" during the 9th bit pulse. The access operation is not performed properly
when the S-35710 Series does not output an acknowledge.

4. Data transmission format
After the start condition transmission, the 1st byte is a slave address and a command (read / write bit) that shows the
transmission direction of the data at the 2nd byte or subsequent bytes.
The slave address of the S-35710 Series is specified to "0110010". The data can be written to the wake-up time
register when read / write bit is "0", and the data of the wake-up time register or the time register can be read when
read / write bit is "1".
When the data can be written to the wake-up time register, input the data from the master device in order of B7 to B0.
The acknowledge ("L") is output from the S-35710 Series whenever a 1-byte data is input.
When the data of the wake-up time register or the time register can be read, the data from the S-35710 Series is
output in order of B7 to B0 in byte unit. Input the acknowledge ("L") from the master device whenever a 1-byte data is
input. However, do not input the acknowledge for the last data byte (NO_ACK). By this, the end of the data read is
informed.
After the master device receives / transmits the acknowledge for the last data byte, input the stop condition to the
S-35710 Series to finish the access operation.
When the master device inputs start condition without inputting stop condition at this time, the S-35710 Series
becomes restart condition, and can transmit / receive the data continuously if the master device inputs the slave
address continuously.

Perform the read operation of the wake-up time register with the restart format. Regarding the restart format, refer to
"4. Data transmission format".
_______
_______
When performing the read operation of the wake-up time register, set the RST pin to "H". If the RST pin is set to "L",
the time register data is read.
Transmit the start condition and the slave address from the master device. The slave address of the S-35710 Series is
specified to "0110010". Next, transmit "0" to the read / write bit.
B7 in the 2nd byte is an address pointer. Set B7 to "0" when reading the wake-up time register. Next, transmit the
dummy data to B6 to B1. Make sure to set B0 to "1" since it is a test bit. This processing is called "dummy write".
Then transmit the start condition, the slave address and the read / write bit. The data of the wake-up time register can
be read when the read / write bit is set to "1".
Consequently, the data of the wake-up time register is output from the S-35710 Series. Each byte from B7 is
transmitted.
When the read operation of the wake-up time register is finished, transmit "1" (NO_ACK) to the acknowledge after B0
output from the master device, and then transmit the stop condition.
The wake-up time register is a 3-byte register. "1" is read if the read operation is performed continuously after reading
3 bytes of the wake-up time register.
Regarding the wake-up time register, refer to " Configuration of Registers".
Moreover, the internal address pointer is reset if recognizing the stop condition. Therefore, do not transmit the stop
condition after dummy write operation. The time register is read if performing the read operation of the register after
transmitting the stop condition.

Release of SDA
_______
The RST pin of the S-35710 Series does not perform the reset operation of the communication interface. Therefore,
the stop condition is input to reset the internal interface circuit usually.
However, the S-35710 Series does not accept the stop condition from the master device when in the status that SDA
outputs "L" (at the time of acknowledge outputting or reading). Consequently, it is necessary to finish the acknowledge
output or read operation. Figure 30 shows the SDA release method.
First, input the start condition from the master device (since SDA of the S-35710 Series outputs "L", the S-35710 Series
can not detect the start condition). Next, input the clocks for 1-byte data access (9 clocks) from SCL. During the time,
release SDA of the master device. By this, the SDA input / output before communication interrupt is completed, and
SDA of the S-35710 Series becomes release status. Continuously, if the stop condition is input, the internal circuit
resets and the communication returns to normal status.
It is strongly recommended that the SDA release method is performed at the time of system initialization after the power
supply voltage of the master device is raised.

2. Operation at power-on
_______
At power-on, the reset signal after chattering elimination is "L" regardless of the RST pin status. Consequently, the
S-35710 Series becomes initial status (Refer to "Figure 16 Status Transition Diagram of One-shot Loop
Time-out (Nch Open-drain Output)", "Figure 17 Status Transition Diagram of One-shot Loop Time-out (CMOS
Output)" and "Figure 20 Status Transition Diagram of Handshake Time-out (Nch Open-drain Output)",
"Figure 21 Status Transition Diagram of Handshake Time-out (CMOS Output)") and can not perform write
operation to the wake-up time register. When the reset signal after chattering elimination is "L", the no acknowledge is
output in the 2nd or subserquent bytes if write operation is performed to the wake-up time register.
If the crystal oscillation circuit starts to oscillate after power-on, the clock operates and the reset signal after chattering
elimination becomes "H", the S-35710 Series then migrates to read mode. This makes the write operation to the
wake-up time register possible. Figure 35 shows the timing chart at power-on.
The write-disable time period of the wake-up time register showed in Figure 35 changes according to the oscillation
start time. If the no acknowledge is output from the S-35710 Series at the time of write operation to the wake-up time
register immediately after power-on, it is recommended to set a time interval of approximately 0.5 seconds to 1 second
for the next communication until the oscillation is stabilized.

Configuration of Crystal Oscillation Circuit
Since the S-35710 Series has built-in capacitors (Cg and Cd), adjustment of oscillation frequency is unnecessary.
However, the crystal oscillation circuit is sensitive to external noise and parasitic capacitance (CP), these effects may
become a factor to worsen the clock accuracy. Therefore, the following steps are recommended for optimizing the
configuration of crystal oscillation circuit.
• Locate the bypass capacitor adjacent to the power supply pin of the S-35710 Series.
• Place the S-35710 Series and the crystal oscillator as close to each other as possible, and shorten the substrate wiring.
• Increase the insulation resistance between pins and the substrate wiring patterns of XIN and XOUT.
• Do not place any signal or power lines close to the crystal oscillation circuit.
• Locate the GND layer immediately below the crystal oscillation circuit.
(In the case of a multi-layer board, only the layer farthest from the crystal oscillation circuit should be located as the
GND layer. Do not locate a circuit pattern on the intermediate layers.)
