AD0, AD1 pins (Address input) To set the slave address, connect the AD0 and AD1 pins to VSS / VDD or set them open. When connecting them to VSS / VDD, set the value for a resistor at 500 or less. When setting them open, avoid to apply noise. The value for capacitor is 100 pF or less for the AD0 and AD1 pins. Users are able to set 8 types of slave address by using the combination of the AD0 and AD1 pins. The S-5851A Series verifies if the slave address set by user matches with the slave address transmitted from the master device or not, so that one S-5851A Series is selected from the devices connected onto the bus. 2. SDA pin (I/O for serial data) The SDA pin transmits serial data bi-directionally, is comprised of a signal input pin and a pin with Nch 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 VDD by a resistor.

Configuration of register The S-5851A Series has a temperature register for reading temperature data, a configuration register to set operations of the S-5851A Series and a pointer register that sets which register will operate Read/Write. Pointer register Temperature register SDA Interface circuit SCL Configuration register Figure 11 Configuration of Register 2. Pointer register The pointer register is an 8-bit register that sets which register will operate Read/Write. Write 00h in the pointer register enables to Read the temperature register. Write 01h enables to Read/Write the configuration register. The value is 00h after power-up/reset of the pointer register. Users are not able to read the point register directly. When you are uncertain of the value in the pointer register, designate the pointer register again. 0 0 0 0 0 0 MSB 0 P0 LSB Figure 12 Configuration of Pointer Register Seiko Instruments Inc. 11 2-WIRE DIGITAL TEMPERATURE SENSOR S-5851A Series Rev. 2.1_00 3. Temperature register The temperature register is a 12-bit Read-only register and stores the latest temperature data. To gain all data, Read 2 bytes. Its first 12 bits are temperature data and 0 is output in other bits. The temperature register outputs 0C until the first conversion has finished after power-up or reset. First byte Second byte T11 T10 T9 T8 T7 T6 T5 T4 T3 T2 T1 T0 0 0 0 0 MSB LSB Figure 13 Configuration of Temperature Register The 12 bits T11 to T0 show temperature. The highest bit of temperature data (T11) shows positive/negative in temperature. Its resolution is 0.0625C. Table 10 shows the typical temperature and temperature data. It is unnecessary to receive all data in the temperature register. Users are able to finish transmission by inputting a stop condition without sending an acknowledgment signal back from the master device, after Read the first byte in the temperature register.

Configuration register The configuration register is an 8-bit Read/Write register, and stores bit which controls operations of the S-5851A Series. The Read/Write operation can be performed from MSB. All bits are 0 after power-up/reset of this configuration register. In case of rewriting bit data except SD, OS bits, the bit data will be omitted. OS 0 0 0 0 0 MSB 0 SD LSB Figure 14 Configuration Register 4. 1 Shutdown mode (SD) Write 1 in the shutdown mode bit (SD) in the configuration register stops the circuits except the serial interface, thus enables to reduce power consumption. By this mode, current comsumption will decrease to 1 A (typ.) or less. This mode is valid after the current conversion. By Write 0 in the shutdown mode bit (SD), the S-5851A Series returns to the normal status in which the S-5851A Series continues updating temperature data. Users can always read the latest temperature data. 4. 2 One-shot mode (OS) The S-5851A Series features the one-shot temperature measure mode. In the shutdown mode, By Write 1 in the one-shot mode bit (OS) in the configuration register, the S-5851A Series starts converting temperature that is done only once. The S-5851A Series finishes updating data in the temperature register after this single temperature conversion, the S-5851A Series returns to the shutdown mode again. When continuous temperature monitoring is unnecessary, this mode reduces consumption power. Write 1 in the one-shot mode bit (OS) in the normal status, the one-shot mode bit (OS) keeps 1 until the current temperature data has finished updating. After this updating, the one-shot mode bit (OS) is set to 0 to indicate the upload completion. Seiko Instruments Inc. 13 2-WIRE DIGITAL TEMPERATURE SENSOR S-5851A Series Rev. 2.1_00 Operation The S-5851A Series is a digital temperature sensor with 2-wire serial interface. By transmission using the SCL and SDA pins, users are able to Read temperature data and set the various modes for the S-5851A Series. Connect a bypass capacitor of 0.1 F between the VDD and VSS pins for proper temperature data. 1. Start condition A start condition starts by changing the SDA line from "H" to "L" while the SCL line is "H". All operations start with a start condition. 2. Stop condition A stop condition starts by changing the SDA line from "L" to "H" while the SCL line is "H". During Read sequence if the S-5851A Series receives a stop condition, its Read operation is interrupted. During Write sequence if the S-5851A Series receives a stop condition, the S-5851A Series finishes installing Write data.

Data transmission Data is transmitted by changing the SDA line while the SCL line is "L". If the SDA line changes while the SCL line is "H", the S-5851A Series goes in the start or stop condition status. SCL "L" "L" "L" SDA Figure 16 Data Transmission Timing 4. Acknowledgment Data is transmitted sequentially in 8-bit. Changing the SDA line to "L" indicates that the devices on the system bus have received data, thus the devices send an acknowledgment signal back during the 9th clock of cycle.

Device addressing To start the transmission, the master device on the system generates a start condition for the slave address. After that, the master device transmits the 7-bit slave address and the 1-bit Read/Write instruction code to the SDA bus. The higher 4 bits of the slave address are device code, and are fixed to "1001". The next 3 bits (A2, A1, A0) are used to select the devices on the system bus, and they are compared with the slave address which is set beforehand by the address input pins (AD1, AD0). If the comparison result matches, the S-5851A Series sends an acknowledgment signal back at the 9th clock of cycle. Table 11 shows the settings for the address input pins (AD1, AD0) and the slave address. The the S-5851A Series does not send an acknowledgment signal back unless the slave address matches.

Configuration register's Write operation When the S-5851A Series receives the 7-bit slave address and the Read/Write instruction code "0" after receiving a start condition, it generates an acknowledgment signal. Next, it receives the 8-bit pointer register's data, and generates an acknowledgment signal. After receiving 8-bit Write data, it rewrites data in the configuration register designated by user, and generates an acknowledgment signal. It receives a stop condition so that the Write operation is finished.

Read operation 7. 1 Read by register-designation To read data in the register set by user arbitrarily, use this function Read by register designation. Beforehand, do dummy write as follows to set the pointer register. When the S-5851A Series receives 7-bit slave address and the Read/Write instruction code "0" after receiving a start condition, it generates an acknowledgment signal. Next, the S-5851A Series receives 8-bit pointer register's data and generates an acknowledgment signal. By these operations, users can set the pointer register. And the S-5851A Series receives 7-bit slave address and the Read/Write instruction code "1" after receiving a start condition, it generates an acknowledgment signal. 8-bit data in the register designated by user will be output synchronizing with the SCL clock from the S-5851A Series. After these operations, the master device sends a stop condition not outputting an acknowledgment signal so that the Read operation is finished.

As long as the master device recognizes values of the pointer's data, users can read current data in the pointer register without designation. This is current register read. In case that the S-5851A Series's pointer register is indicating the temperature register, the S-5851A Series receives 7-bit slave address and the Read/Write instruction code "1" after receiving a start condition, it generates an acknowledgment signal. Next, the first byte data in the temperature register will be output from the S-5851A Series synchronizing with the SCL clock. After that, the master device outputs an acknowledgment signal, the S-5851A Series outputs 4 bits from MSB of the second byte in the temperature register, and 4 bits from LSB are zero. After these operations, the master device sends a stop condition so that the Read operation is finished.

General call After 2-wire interface general call (0000000), the S-5851A Series sends back an acknowledgment signal when the 8th bit is set to 0. And when the second byte is 00000100, the S-5851A Series reinstalls the status of the AD0 and AD1 pins and sends back an acknowledgment signal without resetting the inside status. But when the second byte is 00000110, the S-5851A Series resets its inside all, and goes back itself to the status immediately after power-up. 18 Seiko Instruments Inc. 2-WIRE DIGITAL TEMPERATURE SENSOR S-5851A Series Rev. 2.1_00 Operation during the Low Power Supply Voltage The S-5851A Series has a low power supply voltage detection circuit, stops the interface circuit when the power supply voltage drops to the level of the detection voltage or less. The detection voltage is 1.9 V typ., the release voltage is 2.0 V typ. Power supply voltage Release voltage 2.0 V typ. Detection voltage 1.9 V typ. Reset internal circuit Interface circuit stops Figure 23 Operation during the Low Power Supply Voltage How to Reset S-5851A Series Which status the S-5851A Series is in, users can reset the S-5851A Series externally by following two ways. * Set the power supply voltage at 0 V once in order to get it back to the range of operating voltage again. Have a period at least 10 ms or more to set the power supply voltage at 0 V. * Release the bus, after that, do the reset instruction for general call. First, input a start condition and send the 9 clocks (dummy clock) to the SCL line. During this, set the master device to input "H" to the SDA line. By this operation the S-5851A Series stops outputting an acknowledgment signal or outputting data, then input a start condition and a stop condition. After that, send a general call (0000000) and send 0 as the 8th bit. And send 00000110 as the second byte. Consequently, the S-5851A Series resets its inside status.
