The S-7760A is a programmable port controller IC comprised of an E PROM, a control circuit for data output, a circuit to
prevent malfunction caused by low power supply voltage and others.
This IC operates at 400 kHz and interfaces with exteriors via I2C-bus, controls an 8ch digital output with a serial signal.
Among the digital output ports of 8 channels, the lower 4 channels have a timer function so that at each port, users are able
to set the default value and inverted delay time. In the higher 4 channels, setting the fixed output is available at each port.
The default value is maintained despite power-off because this IC has an E2PROM.
The S-7760A is able to be used to control ON/OFF for the chips surrounding MPU and to output the default data that
devices fundamentally have.

General Description of Pin Function
1. SDA (Serial data I/O) pin
The SDA pin transmits serial data bi-directionally, is comprised of a signal input pin and a pin with Nch transistor open
drain output. In use, generally, connect the SDA line to any other device which has the open-drain or open-collector
output with Wired-OR connection by pulling up to VCCH by a resistor.
2. SCL (Input for serial clock) pin
The SCL pin is an input pin for serial clock, processes a signal at a rising/falling edge of SCL clock. Pay attention fully
to the rising/falling time and comply with specifications.
3. WP (Input for Write protect) pin
2
This pin performs Write Protect to E PROM (This pin does not have a function for Write protect to the register).
Set the WP pin in VCCH when using the Write Protect function. If not, set the WP pin to GND.
4. TIMEN (Input for timer enable) pin
The TIMEN pin controls enable (“H”)/disable (“L”)/Start (“L”→”H”) in the timer action (inversion of digital output due to
elapsed period). Refer to the description of related register in “ Command” and “ Condition to Start Timer”
regarding details of timer action.
5. DO0, DO1, DO2, DO3 (Digital output) pin
These are lower 4 channels in the digital output ports. Their default values are equal to the ones of a control port
register during output. These lower 4 channels are for timer action. Its output inverts after; the timer starts and delay
time has elapsed.
6. DO4, DO5, DO6, DO7 (Digital output) pin
These are the higher 4 channels in the digital output ports. Their default values are equal to the ones of a control port
register during output. These higher 4 channels have fixed output. The elapsed period does not make outputs
inverted.
7. TEST pin
This is an input pin for testing. Connect it to the VCCH pin or GND.
8. VSS pin
Connect to GND.
9. VCCH pin
Except for the output ports, the power supply is applied to the entire circuit via this pin. Regarding the voltage’s value
to be applied to this pin, refer to “ Recommended Operating Conditions”.
10. VCCL pin
This pin is to apply the power supply for the output ports. Regarding the voltage’s value to be applied to this pin, refer
to “ Recommended Operating Conditions”.

The SDA, SCL and TIMEN pins are low voltage input types.
In low voltage input type, even when the power supply voltage at MPU is lower than the one of the S-7760A, setting a
level-shifter for an interface signal is unnecessary.
Independent of the power supply voltage, VIH2 and VIL2 are constant. Each of them is VIH2 ≥ 1.5 V, VIL2 ≤ 0.3 V.

S-7760A
Device Addressing
To start communication, the master device (MPU) on the system generates a start condition for the slave device
(S-7760A). After that, the master device sends a device address with 7-bit length and Read/Write instruction code with
1-bit length on the SDA bus. The higher 3 bits in a device address (DC2, DC1, DC0) are device codes, which are fixed to
“100”. Command is omitted if a device code does not correspond. Set the command in the following 4 bits (C3, C2, C1,
C0). Next, by selecting either of Read or Write by Read/Write bit, the S-7760A sends an acknowledgement signal back. If
the second byte is Read, MPU sends an acknowledgement signal back after outputting data Read with 8-bit length. If it is
Write, after outputting Write data with 8-bit length, the S-7760A sends an acknowledgement signal back. To finish these
sequential commands, the S-7760A generates a stop condition as its final procedure.
There is a 1-byte command for the S-7760A, but inputting the second byte as a dummy does not affect on this device
addressing. In this case, the operation for the second byte is as well as for Read/Write because of the bit corresponding to
Read/Write in the first byte.

*3.
It is register access mode when R / W = 0, E2PROM access mode when R / W = 1.
By Switching access to register/E2PROM, users can select either register or E2PROM when Read/Write. Refer to
“ Register and E2PROM”.
Register and E2PROM
This IC has an E2PROM. Data in the E2PROM is maintained despite power-off. The S-7760A has a register which
corresponds to the data in the E2PROM, the S-7760A sends data to this corresponding register during power-on
(releasing detection of the low voltage) and inputting the reload command. The following registers are the ones to be
reloaded;
࣭Control port register (1-byte)
࣭Timer scale setting register (1-byte)
࣭DO3 to 0 Timer setting register (1-byte in each port, total 4 bytes)
Users are able to switch access between corresponding register and E2PROM by “Switching access to register/E2PROM”
command. Immediately after power-on, the S-7760A is in “register access mode”. In this register access mode, only the
register is rewritten, the E2PROM maintains the prior data. But in “E2PROM access mode”, both data in the register and
the E2PROM is rewritten. In data Read, access mode data which is being selected by user; is read.

S-7760A
Command
1. Reload
This is a 1-byte command. Users can reload by inputting either of R / W in 0/1. When inputting this command, the
data corresponding to the E2PROM is loaded to the register. After completing reload, (if the condition is satisfied), the
timer action starts. The reload command is not accepted during the timer action (from its start to the final invert of
output). Refer to “ Condition to Start Timer” regarding details.
2. Switching access to register/E2PROM
This is a 1-byte command. The mode is in “register access mode” when this command is R / W = 0, “E2PROM
access mode” when this command is R / W = 1. The register corresponding to the E2PROM is the one to be
reloaded. In register access mode, only the register is rewritten, the E2PROM maintains the prior data. In “E2PROM
access mode”, both data in the register and E2PROM is rewritten.
3. Timer enable register
A timer enable register is a 4-bit register for Write only (it sends back FFh during Read). By setting each bit in the
register in “1”, an oscillation circuit starts, output from the lower 4ch ports (DO3 to 0) invert after the elapsed period
which is set by a timer setting register. This action is called “timer action”. This timer action starts at the point when
receiving TEN0 which is LSB in the register. The bit automatically goes back in “0” after writing “1” in the timer enable
register. Users cannot write in this register during the timer action (from the start to the final invert of output). This
register is not the one to be reloaded, thus it does not have the data which corresponds to the E2PROM. To start a
timer, Condition AND with TIMEN = High is required. Refer to“ Condition to Start Timer” regarding details.

Control port register is an 8-bit register. Users can set output data which is from output ports (DO7 to 0). If data is “1”,
output is “H”, and if it is “0”, output is “L”. This register is the one to be reloaded. Data in this register does not change
even if output from the port is inverted by timer action.

The lower 4 bits are registers for timer scale setting. Users can set, whether short-time or long-time, time reference

The higher 4 bits are Read/Write-able bits, however, they do not affect on circuit action because DO7 to 4 have fixed
output. This register is the one to be reloaded.

6. DO0 to 3 Timer setting registers
These registers are 8-bit registers which correspond to each port, with these registers, users can set delay time for the
change of output at output ports (DO0 to 3). When delay time is set, its value is a multiple of timer scale. The multiple
is integers 1 to 8. By setting the corresponding bits seen in Figure 14 in “1”, a multiple is selected to determine delay
time. For each port, set only 1-bit in the bit that you set “1”. And if setting all 8 bits in “0”, output is not inverted even if
the condition to start a timer matches.

Figure 14 shows a short-time setting scale. In case of a long-time setting scale, substitute T with LT.
Each timer scale is as follow;
Short-time setting scale Typ. = T = 10 μs
Long-time setting scale Typ. = LT = 640 μs
If setting “1” in B6 bit in the DO3 timer setting register, “1” in TS3 in the timer scale register, DO3 inverts at delay time
of 70 μs (7 × 10 μs). Other examples are shown in Figure 15.

The condition to start a timer is three, A/B/C.
During power-on of power supply VCCH, the S-7760A automatically reloads (transmits data from the E2PROM to the
register). In this case, if TIMEN = “H”, the S-7760A goes in the timer action after reloading. Thus the sequential action is;
after power-on of power supply VCCH, reload → timer. This is as well if the status changed from detection to release of
the low power supply voltage.
The timer action does not stop in the middle of its process even if setting TIMEN in “H” → “L” after the timer action has
started. The oscillation circuit is generally being stopped, but the oscillation starts when the condition to start a timer
matches. And it stops by finishing the timer action (the final invert of output).

In the Write operation to the E2PROM, the Write operation starts with a stop condition, the S-7760A finishes it after the
period to Write (max. 5 ms) has elapsed. During Write to the E2PROM, all operations are inhibited to be performed
and the S-7760A does not send back any acknowledgment signals for command inputs.

Fix the WP pin during the period; from rising of SCL at installing the last bit in Write data until the completion of Write
period (max. 5 ms).

Acknowledgment polling
Acknowledge polling is used to find when the Write operation has completed. After receiving a stop condition the Write
operation has once started, all operations are inhibited to be performed so that the S-7760A cannot respond to the
signals transmitted from the master device. The master device sends a start condition, the device address and
Read/Write instruction code to the S-7760A (slave device), and detects the response from the slave device. It is
possible to find when the Write operation has completed. Thus if the slave device does not send an acknowledgment
signal back, the Write operation is in progress. If it sends an acknowledgment signal back, the Write operation has
completed. Fix the WP pin until an acknowledgment is confirmed. It is recommended to use the Read instruction “1”
for the Read/Write instruction code transmitted from the master device during acknowledgment polling.
6. 4
Irregular action
In the middle of inputting Write data, if inputting a stop condition in clock less than the specified data length (8-bit), the
S-7760A does not perform Write to the E2PROM. And it either does not perform Write to the E2PROM if receiving a
stop condition after receiving data over 9-bit. However, data in the register has been rewritten at the point when the
S-7760A has received the specified length data. Be sure not to input clock which exceeds the specified value due to
noise or other causes.

Write Protect Function during the Low Power Supply Voltage
The S-7760A has a built-in detection circuit which operates with the low power supply voltage, cancels Write when the
power supply voltage drops and power-on. Its detection voltage is 1.75 V (Typ.) and the release voltage is 2.05 V (Typ.),
and its hysteresis is approx. 0.3 V.
The S-7760A cancels Write by detecting a low power supply voltage when it receives a stop condition.
Both in the data transmission and the Write operation, data in the address written during the low power supply voltage is
not assured.

S-7760A
How to Use S-7760A
1.
SDA I/O pin and SCL input pin
In consideration of I2C-bus protocol function, the SDA I/O and SCL input pins*1 should be connected with a pull-up
resister of 1 to 5 kΩ.
The S-7760A cannot transmit normally without using a pull-up resistor.
*1.
2.
In the case that the SCL input pin of the S-7760A is connected to the tri-state output pin in the master device,
connect the SCL input pin with a pull-up resistor as well in order not to set the SCL input pin in high impedance.
This prevents the S-7760A from error caused by high impedance from the tri-state pin when resetting the master
device during the voltage drop.
Reset after transmission interruption
This IC does not have a pin to reset, but it generally resets the internal circuit by inputting a stop or start condition.
However, in case that transmission is interrupted, for example, only the master device is reset because the power
supply voltage drops during transmission; the internal circuit maintains the status before interruption. If the status is
that the SDA pin outputs “L” (outputs an acknowledge signal or in Read), this IC does not perform the next operation
because it cannot receive a start or stop condition from the master device. Therefore it is necessary to finish
outputting an acknowledgment signal and the Read operation in SDA. Figure 28 shows how to reset.
First, input a start condition. (While the SDA pin is outputting “L”, the S-7760A does not go in the start condition but
this “L” output does not affect on the slave device.) Next, input clock (27 clocks) which is equivalent to 3-byte data
access from the SCL pin. During this procedure, pull up the SDA line which is connected closer to the master device.
Due to this, the SDA pin’s I/O prior to transmission interruption ends so that the SDA pin goes in “H”. After that, by
inputting a stop condition, the S-7760A returns to the status possible to perform the general transmission. It is
recommended to perform this reset when you initialize, after power-on the master device. A circuit for prevention
malfunction by a low power supply voltage is equipped in this IC, thus it automatically resets internally when a low
voltage is applied to this IC.

3. Acknowledgment check
The I2C-bus protocol includes an acknowledgment check function as a handshake function to prevent a
communication error. This function allows detection of a communication failure during data communication between
the master device and the S-7760A.
4. Built-in power-on-clear circuit
The S-7760A has a built-in power-on-clear circuit that initializes itself at the same time during power-on. Unsuccessful
initialization may cause a malfunction. To operate the power-on-clear circuit normally, the following conditions must be
satisfied to raise the power supply voltage.
4. 1 Raising power supply voltage
As shown in Figure 29, raise the power supply voltage from 0.2 V max., within the time defined as tRISE which is the
time required to reach the power supply voltage to be set.
For example, if the power supply voltage is 3.0 V, tRISE = 100 ms as seen in Figure 30. The power supply voltage must
be raised within 100 ms.

When initialization is successfully completed by the power-on-clear circuit, the S-7760A enters the standby status.
If the power-on-clear circuit does not operate, the followings are the possible causes.

(2)
Because the S-7760A has not completed initialization, an instruction previously input is still valid or an
instruction may be inappropriately recognized. In this case, the S-7760A may perform the Write operation.
The voltage drops due to power off while the S-7760A is being accessed. Even if the master device is reset due
to the low power voltage, the S-7760A may malfunction unless the conditions for the power-on-clear operation
are satisfied.

5. Data hold time (tHD. DAT = 0 ns)
If SCL and SDA of the S-7760A are changed at the same time, the timing which takes to reach this IC slightly lags due
to a load on the bus line. As a result, the change in the SDA precedes a falling edge of SCL so that S-7760A may
recognize a start/stop condition.
To avoid this, in the S-7760A, it is recommended to set the delay time of over 0.3 μs for a falling edge of SCL.
In its specs, it is described as the S-7760A works at 0 ns of data hold time, however, take account into the above
action in actual use.

Precautions
• Semiconductor devices must be used within the absolute maximum rating. Special caution is required for the
supply voltage. A momentary surge voltage exceeding the rated value may cause latch-up and malfunction.
Confirm the detailed usage conditions required for each parameter by referring to the data sheet before use.
• If the S-7760A operates with moisture remaining in the circuits, a short circuit may occur between pins, causing a
malfunction. When the S-7760A is taken out of the constant-low-temperature bath during evaluation, the pins of the
S-7760A may be frosted. Note that, if the S-7760A is operated with the pins frosted, the pins may be short-circuited
by moisture, causing a malfunction.
The same applies when the S-7760A is used in an environment where condensation may occur, so care is required.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• ABLIC Inc. assumes no responsibility for the way in which this IC is used in products created using this IC or for the
specifications of that product, nor does ABLIC Inc. assume any responsibility for any infringement of patents or
copyrights by products that include this IC either in Japan or in other countries.
Precautions for WLP Package
• The side of device silicon substrate is exposed to the marking side of device package. Since this portion has lower
strength against the mechanical stress than the standard plastic package, chip, crack, etc. should be careful of the
handing of a package enough. Moreover, the exposed side of silicon has electrical potential of device substrate, and
needs to be kept out of contact with the external potential.
• In this package, the overcoat of the resin of translucence is carried out on the side of device area. Keep it mind that
it may affect the characteristic of a device when exposed a device in the bottom of a high light source.
