FOR AUTOMOTIVE 125°C OPERATION 2-WIRE

CONVENIENCE TIMER

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 ABLIC Inc. 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 The above description is the example of an Nch open-drain output product.

In a CMOS output product, the INT pin output is the inverse logic of the Nch open-drain output product.

1. 1 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

 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

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.

5. Read operation of time register

Transmit the start condition and slave address from the master device. The slave address of the S-35710 Series is

specified to "0110010". Next, the data of the time register can be read when the read / write bit is "1".

The 2nd byte to the 4th byte are used as the time register. Each byte from B7 is transmitted.

When the read operation of the time register is finished, transmit "1" (NO_ACK) to the acknowledge after B0 is output

from the master device, and then transmit the stop condition.

The time register is a 3-byte register. "1" is read if the read operation is performed continuously after reading 3 bytes of

the time register. Regarding the time register, refer to " Configuration of Registers".

Transmit the start condition and 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.

Transmit the 2nd byte data. Set B7 to "1" since it is an address pointer. Set B6 to B1 to "0" or "1" since they are dummy

data. Make sure to set B0 to "1" since it is a test bit.

The 3rd byte to the 5th byte are used as the wake-up time register.

Transmit the stop condition from the master device to finish the access operation.

Regarding the wake-up time register, refer to " Configuration of Registers".

Write operation of the wake-up time register is performed each byte, so transmit the data in 3-byte unit. Note that the

7. Read operation of wake-up time register

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

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 quartz crystal as close to each other as possible, and shorten the wiring.

• Increase the insulation resistance between pins and the board 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.)
