... Table 1 for Ordering Information DESCRIPTION The DS1631, DS1631A, and DS1731 digital thermometers provide 9, 10, 11, or 12-bit temperature readings over a -55°C to +125°C range. The DS1631 and DS1631A thermometer accuracy is ±0.5°C from 0°C to +70°C with 3.0V £ V 3.0V £ V £ 5.5V. The thermostat on all three devices provides custom hysteresis with user-defined trip ...

... The DS1631, DS1631A, and DS1731 communicate over a bidirectional 2-wire serial data bus that consists of a serial clock (SCL) signal and serial data (SDA) signal. The DS1631, DS1631A, and DS1731 interface to the bus through their SCL input pins and open-drain SDA I/O pins. ...

... WRITES The master can write data to the DS1631/DS1631A/DS1731 by issuing an Access Config, Access TH, or Access TL command following the control byte (see Figures 9b and 9d). Since the R/ byte was a 0 (“write”), the DS1631/DS1631A/DS1731 are already prepared to receive data. Therefore, after receiving an ACK in response to the command byte, the master device can immediately begin transmitting data ...

... ACK in response to the command, the master must generate a repeated START followed by a control byte with the same slave address as the first control byte. However, this time the which tells the DS1631/DS1631A/DS1731 that a “read” is being performed. After the DS1631/DS1631A/DS1731 send an ACK in response to this control byte, it begins transmitting the requested data on the next clock cycle ...
