www.sii-ic.com PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) © SII Semiconductor Corporation, 2007-2010 Rev.2.0_01 The S-7760A is a programmable port controller IC comprised of an E 2PROM, 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 defau lt data that devices fundamentally have.  Features

PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) S-7760A Rev.2.0_01  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 sig nal 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 This pin performs Write Protect to E2PROM (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)/RESX (Input for reset bar) pin Select TIMEN or RESX by option. 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. The RESX pin has the negative logic, is a pin to reset. This pin initializes the circuit with “L” input, and performs its regular action (the status of reset release) by inputting “H”. This pin goes in its reload action immediately after releasing reset, thus by initializing, the value of related register is reloaded to the data that E 2PROM has. If a user selects the RESX pin, the TIMEN pin’s function will be invalid so that the internal signal of TIMEN is fixed in “L”. 5. CLK (Clock input)/BPDX (Input for bus pull-down bar) pin As for primary clock for circuits, users can select either from the internal oscillation circuit or input it externally by option. In case of using an external clock input, this pin wor ks as the CLK pin to input clock by itself. In case of using an internal oscillation circuit, users can set this pin as the BPDX pin by option. With “L” input from the BPDX pin, SDA and SCL in I2C-bus interface are forcibly pulled-down. This pin perfo rms its regular action by inputting “H”. Users also can select the setting which does not have an internal oscillation circuit or bus pull-down for this pin. 6. DO0, DO1, DO2, DO3 (Digital output) pin These are lower 4 channels in the digital output ports. Thei r default values are equal to the ones of a control port register during output. These lower 4 channels are for timer ac tion. Its output inverts after; the timer starts and delay time has elapsed. 7. 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. 8. VSS pin Connect to GND. 9. VCCH pin Except for the output ports, the power supp ly 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”.

PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) Rev.2.0_01 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 addr ess 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. A device code can obtain the fixed value selected by option. 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 ei ther 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.

W / R= 1/0 Both execute “reload”. *2. It is register access mode when W / R = 0, E 2PROM access mode when W / R = 1. *3. By Switching access to register/E 2PROM, users can select either register or E2PROM when Read/Write. Refer to “ Register and E2PROM”.  Register and E2PROM This IC has an E 2PROM. Data in the E 2PROM is maintained despite power-off. The S-7760A has a register which corresponds to the data in the E 2PROM, the S-7760A sends data to this corresponding register during power-on (releasing detection of the low voltage) and inputting the reload command. In case of selecting the RESX pin by option, the S-7760A reloads after releasing reset. 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 E 2PROM by “Switching access to register/E2PROM” command. Immediately after power-on, the S-7760A is in “regi ster access mode”. In this register access mode, only the register is rewritten, the E 2PROM maintains the prior data. But in “E 2PROM 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.

PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) Rev.2.0_01 S-7760A  Command 1. Reload This is a 1-byte command. Users can reload by inputting either of W / R 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/E 2PROM This is a 1-byte command. The mode is in “register access mode” when this command is W / R = 0, “E 2PROM access mode” when this command is W / R = 1. The register corresponding to the E 2PROM is the one to be reloaded. In register access mode, only the register is rewritten, the E 2PROM maintains the prior data. In “E 2PROM 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 E 2PROM. The option is available for the condition to start a timer; Condition AND with TIMEN = High, depending on the option. Refer to “  Condition to Start Timer” regarding details.

2 D Regular status Don’t care Write “0” → “1”

2 types of options are available for the condition to start a timer. Select either for each digital output port DO0 to 3; if selecting option 1, the condition to start a timer is three, A/B/C. If in option 2, the condition is D only. In D, the S-7760A does not react to reload and rising of TIMEN. By writing “1” in TEN, not in TIMEN, the timer starts. During power-on of power supply VCCH, the S-7760A automatically reloads (transmits data from the E 2PROM to the register). In this case, TIMEN = “H” and it is in option 1, 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. In selecting “t he option for internal oscillation circuit”, the o scillation circuit is generally being stopped, but th e oscillation starts when the condition to start a timer matches. And it stops by finishing the timer action (the final invert of output).

And the DO7 to 0 pins go in “L”. After that, when the power supply voltage increases more than the level of the release voltage of the circuit for prevention malfunction by low voltage (2.05 V Typ.), data is reloaded from the E 2PROM to the register, the values of DO7 to 0 pins go back to its default.

PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) Rev.2.0_01 S-7760A 6. 3 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 s ends 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 E 2PROM. And it either does not perform Write to the E 2PROM 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.

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. Release voltage (+VDET) 2.05 V Typ. Power supply voltage Hysteresis approx. 0.3 V Detection Voltage (−VDET) 1.75 V Typ. Cancel the Write instruction Figure 31 Operation during Low Power Voltage

Acknowledgment check The I 2C-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 33, raise the power supply voltage from 0.2 V max., within the time defined as t RISE 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 34. The power supply voltage must be raised within 100 ms. 0.2 V VINIT (Max.) tINIT *2 (Max.) tRISE (Max.)

Figure 34 Raising Time of Power Supply Voltage 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. (1) 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, S-7760A may perform the Write operation. (2) 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.

PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) S-7760A Rev.2.0_01  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 ci rcuits, a short circuit may occur between pins, causing a malfunction. When the S-7760A is taken out of the const ant-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.
• Although the IC contains a static electricity protection circui t, static electricity that exceeds the limit of the protection circuit should not be applied.
• SII Semiconductor Corporation assumes no responsibility fo r the way in which this IC is used in products created using this IC or for the specifications of that pro duct, nor does SII Semiconductor Corporation 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 device’s silicon substrate side is exposed to the marking side of the device package. Since this portion has a lower strength against mechanical stress than a standard plastic package, take sufficient care to avoid chips and cracks when handling the package. Moreover , the exposed side of the silicon has the electrical potential of the device substrate, and needs to be kept out of contact with the external potential.
• In this package, the transistor area side is overcoated with a translucent resin. Keep in mind that the characteristics of the package may be affected if the device is exposed under an intensive light source.
