Device Operation
Commands used to configure and control the operation of the AT30TS750 are sent to the device
from the Master via the serial interface. Likewise, the Master can read the temperature data from
the AT30TS750 via the serial interface. However, since multiple slave devices can reside on the
serial bus, each slave device must have its own unique 7-bit address so that the Master can
access each device independently.
For the AT30TS750, the first four most-significant bits (MSBs) of its 7-bit address are the Device
Type Identifier and are fixed at 1001. The remaining three LSBs correspond to the states of the
hard-wired A2-0 address pins. For example, if the A2-0 pins are connected to GND, then the 7-bit
device address would be 1001000.
In order for the Master to select and access the AT30TS750, the Master must first initiate a
START condition. Following the START condition, the Master must output the device address
byte. The device address byte consists of the 7-bit device address plus a Read/Write (R/W
_
)
control bit, which indicates whether the Master will be performing a read or a write to the
AT30TS750. If the R/W
_
control bit is a logic “1”, then the Master will be reading data from the
AT30TS750. Alternatively, if the R/W
_
control bit is a logic “0”, then the Master will be writing data
to the AT30TS750.

If the 7-bit address sent by the Master matches that of the AT30TS750, then the device will
respond with an ACK after it has received the full address byte. If there is an address mismatch,
then the AT30TS750 will respond with a NACK and return to the idle state.
