The TMP103 is two-wire and SMBus compatible. Figure 1 to Figure 5 describe the various operations on the TMP103. Parameters for Figure 1 are defined in Timing Requirements. Bus definitions are:

Bus Idle: Both SDA and SCL lines remain high.

Start Data Transfer: A change in the state of the SDA line, from high to low, while the SCL line is high, defines a START condition. Each data transfer is initiated with a START condition.

Stop Data Transfer: A change in the state of the SDA line from low to high while the SCL line is high defines a STOP condition. Each data transfer is terminated with a repeated START or STOP condition.

Data Transfer: The number of data bytes transferred between a START and a STOP condition is not limited and is determined by the master device.

Acknowledge: Each receiving device, when addressed, is obliged to generate an Acknowledge bit. A device that acknowledges must pull down the SDA line during the Acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the Acknowledge clock pulse. Setup and hold times must be taken into account. On a master receive, the termination of the data transfer can be signaled by the master generating a Not-Acknowledge (1) on the last byte transmitted by the slave.

1. All TMP103 devices on the bus acknowledge the byte.
2. The master must issue an acknowledge for each byte read to read all of the TMP103 devices on the bus.
3. Three TMP103 devices used in this case; up to eight devices can be used (see Table 2).
