Single-Channel 1-Wire Master
I2C Interface
General Characteristics
The I2C bus uses a data line (SDA) plus a clock signal
(SCL) for communication. Both SDA and SCL are bidi-
rectional lines, connected to a positive supply voltage
through a pullup resistor. When there is no communica-
tion, both lines are high. The output stages of devices
connected to the bus must have an open drain or open
collector to perform the wired-AND function. Data on
the I2C bus can be transferred at rates of up to
100kbps in standard mode and up to 400kbps in fast
mode. The DS2482-100 works in both modes.
A device that sends data on the bus is defined as a
transmitter, and a device receiving data is defined as a
receiver. The device that controls the communication is
called a master. The devices that are controlled by the
master are slaves. To be individually accessed, each
device must have a slave address that does not conflict
with other devices on the bus.
Data transfers can be initiated only when the bus is not
busy. The master generates the serial clock (SCL), con-
trols the bus access, generates the START and STOP
conditions, and determines the number of data bytes
transferred between START and STOP (Figure 7). Data
is transferred in bytes with the most significant bit being
transmitted first. After each byte follows an acknowledge
bit to allow synchronization between master and slave.
Slave Address
The slave address to which the DS2482-100 responds
is shown in Figure 8. The logic state at the address pins
AD0 and AD1 determines the value of the address bits
A0 and A1. The address pins allow the device to
respond to one of four possible slave addresses. The
slave address is part of the slave address/control byte.
The last bit of the slave address/control byte (R/W)
defines the data direction. When set to 0, subsequent
data flows from master to slave (write access); when
set to 1, data flows from slave to master (read access).
