DS1775

Digital Thermometer and Thermostat in SOT23

Figure 3 details how data transfer is accomplished on the

2-wire bus. Depending upon the state of the R/W bit, two

types of data transfer are possible:

2) Slave transmitter mode: The ﬁrst byte is received

and handled as in the slave receiver mode. However,

in this mode, the direction bit indicates that the trans-

fer direction is reversed. Serial data is transmitted on

SDA by the DS1775 while the serial clock is input on

SCL. START and STOP conditions are recognized as

the beginning and end of a serial transfer.

1) Data transfer from a master transmitter to a slave

receiver. The ﬁrst byte transmitted by the master is

the slave address. Next follows a number of data

bytes. The slave returns an acknowledge bit after

each received byte.

Slave Address

2) Data transfer from a slave transmitter to a master

receiver. The ﬁrst byte (the slave address) is trans-

mitted by the master. The slave then returns an ac-

knowledge bit. Next follows a number of data bytes

transmitted by the slave to the master. The master re-

turns an acknowledge bit after all received bytes other

than the last byte. At the end of the last received byte,

a ‘not acknowledge’ is returned.

A control byte is the first byte received following the

START condition from the master device. The control

byte consists of a 4-bit control code; for the DS1775, this

is set as 1001 binary for read and write operations. The

next three bits of the control byte are the device select bits

(A2, A1, A0). These bits are set to 000 (A2 = 0, A1 = 0, A0

= 0) for the DS1775R and vary according to the device’s

part number as specified in the Ordering Information

table. They are used by the master device to select which

of eight devices are to be accessed. The set bits are in

effect the three least significant bits of the slave address.

The last bit of the control byte (R/W) defines the opera-

tion to be performed. When set to a 1 a read operation is

selected; when set to a 0 a write operation is selected.

Following the START condition, the DS1775 monitors the

SDA bus checking the device type identifier being trans-

mitted. Upon receiving the 1001 code and appropriate

device select bits of 000, the DS1775 outputs an acknowl-

edge signal on the SDA line. See Figure 4.

The master device generates all the serial clock pulses

and the START and STOP conditions. A transfer is ended

with a STOP condition or with a repeated START condi-

tion. Since a repeated START condition is also the begin-

ning of the next serial transfer, the bus is not released.

The DS1775 can operate in the following two modes:

1) Slave receiver mode: Serial data and clock are re-

ceived through SDA and SCL. After each byte is re-

ceived, an acknowledge bit is transmitted. START

and STOP conditions are recognized as the begin-

ning and end of a serial transfer. Address recognition

is performed by hardware after reception of the slave

address and direction bit.
