its ALERT pin will become inactive at the completion of the
SMBus Alert command. If the TMP275 loses the
arbitration, its ALERT pin will remain active.
GENERAL CALL
The TMP275 responds to a Two-Wire General Call
address (0000000) if the eighth bit is 0. The device
acknowledges the General Call address and responds to
commands in the second byte. If the second byte is
00000100, the TMP275 latches the status of the address
pins, but does not reset. If the second byte is 00000110,
the TMP275 latches the status of the address pins and
resets the internal registers to the power-up values.
HIGH-SPEED MODE
In order for the Two-Wire bus to operate at frequencies
above 400kHz, the master device must issue an Hs-mode
master code (00001XXX) as the first byte after a START
condition to switch the bus to high-speed operation. The
TMP275 will not acknowledge this byte, but will switch its
input filters on SDA and SCL and its output filters on SDA
to operate in Hs-mode, allowing transfers at up to 3.4MHz.
After the Hs-mode master code has been issued, the
master transmits a Two-Wire slave address to initiate a
data transfer operation. The bus continues to operate in
Hs-mode until a STOP condition occurs on the bus. Upon
receiving the STOP condition, the TMP275 switches the
input and output filters back to fast-mode operation.
TIMEOUT FUNCTION
The TMP275 resets the serial interface if either SCL or
SDA is held LOW for 54ms (typ) between a START and
STOP condition. The TMP275 releases the bus if it is
pulled LOW and waits for a START condition. To avoid
activating the timeout function, it is necessary to maintain
a communication speed of at least 1kHz for SCL operating
frequency.
TIMING DIAGRAMS
The TMP275 is Two-Wire and SMBus-compatible.
Figure 4 to Figure 7 describe the various operations on the
TMP275. Bus definitions are given below. Parameters for
Figure 4 are defined in Table 12.
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. The receiver
acknowledges the transfer of data.
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 on the last byte that has been
transmitted by the slave.
