Pin Description
SCL: The Serial Clock input pin accepts the Serial Clock
generated by the Master (Host).
SDA: The Serial Data I/O pin receives input data and transmits
data stored in the TS registers. In transmit mode, this pin is
open drain. Data is acquired on the positive edge, and is
delivered on the negative edge of SCL.
A0, A1 and A2: The Address pins accept the device address.
These pins have on−chip pull−down resistors.
EVENT: The open−drain EVENT pin can be programmed
to signal over/under temperature limit conditions.
Power−On Reset (POR)
The CAT34TS00 incorporates Power−On Reset (POR)
circuitry which protects the device against powering up to an
undetermined logic state. As VCC exceeds the POR trigger
level, the device will power up into conversion mode. When
VCC drops below the POR trigger level, the device will
power down into Reset mode.
This bi−directional POR behavior protects CAT34TS00
against brown−out failure following a temporary loss of
power. The POR trigger level is set below the minimum
operating VCC level.
Device Interface
The CAT34TS00 supports the Inter−Integrated Circuit
(I2C) and the System Management Bus (SMBus) data
transmission protocols. These protocols describe serial
communication between transmitters and receivers sharing a
2−wire data bus. Data flow is controlled by a Master device,
which generates the serial clock and the START and STOP
conditions. The CAT34TS00 acts as a Slave device. Master
and Slave alternate as transmitter and receiver. Up to 8

devices
may

bus
simultaneously, and can be individually addressed by
matching the logic state of the address inputs A0, A1, and A2.
The CAT34TS00 contains eight 16−bit internal registers
which can be accessed for write and read using the
I2C/SMBus protocol.
I2C/SMBus Protocol
The I2C/SMBus uses two ‘wires’, one for clock (SCL) and
one for data (SDA). The two wires are connected to the VCC
supply via pull−up resistors. Master and Slave devices
connect to the bus via their respective SCL and SDA pins.
The transmitting device pulls down the SDA line to
‘transmit’ a ‘0’ and releases it to ‘transmit’ a ‘1’.
Data transfer may be initiated only when the bus is not
busy (see A.C. Characteristics).
During data transfer, the SDA line must remain stable
while the SCL line is HIGH. An SDA transition while SCL
is HIGH will be interpreted as a START or STOP condition
(Figure 3).
START
The START condition precedes all commands. It consists
of a HIGH to LOW transition on SDA while SCL is HIGH.
The START acts as a ‘wake−up’ call to all Slaves. Absent a
START, a Slave will not respond to commands.
STOP
The STOP condition completes all commands. It consists
of a LOW to HIGH transition on SDA while SCL is HIGH.
The STOP tells the Slave that no more data will be written
to or read from the Slave.
Device Addressing
The Master initiates data transfer by creating a START
condition on the bus. The Master then broadcasts an 8−bit
serial Slave address. The first 4 bits of the Slave address (the
preamble) are fixed at binary 0011 (3hex). The next 3 bits,
A2, A1 and A0, select one of 8 possible Slave devices. The
last bit, R/W, specifies whether a Read (1) or Write (0)
operation is being performed.
Acknowledge
A matching Slave address is acknowledged (ACK) by the
Slave by pulling down the SDA line during the 9th clock
cycle (Figure 4). After that, the Slave will acknowledge all
data bytes sent to the bus by the Master. When the Slave is
the transmitter, the Master will in turn acknowledge data
bytes in the 9th clock cycle. The Slave will stop transmitting
after the Master does not respond with acknowledge
(NoACK) and then issues a STOP. Bus timing is illustrated
in Figure 5.
