FUNCTIONAL DESCRIPTION
4.4
Data Valid (D)
The 24C01C supports a bidirectional 2-wire bus and
data transmission protocol. A device that sends data
onto the bus is defined as transmitter, and a device
receiving data as receiver. The bus has to be controlled
by a master device that generates the Serial Clock
(SCL), controls the bus access, and generates the Start
and Stop conditions, while the 24C01C works as slave.
Both master and slave can operate as transmitter or
receiver, but the master device determines which mode
is activated.
The state of the data line represents valid data when,
after a Start condition, the data line is stable for the
duration of the high period of the clock signal.
The data on the line must be changed during the low
period of the clock signal. There is one bit of data per
clock pulse.
Each data transfer is initiated with a Start condition and
terminated with a Stop condition. The number of the
data bytes transferred between the Start and Stop
conditions is determined by the master device and is

The following bus protocol has been defined:
? Data transfer may be initiated only when the bus
is not busy.
? During data transfer, the data line must remain
stable whenever the clock line is high. Changes in
the data line while the clock line is high will be
interpreted as a Start or Stop condition.
Accordingly, the following bus conditions have been

byte. The master device must generate an extra clock

slave by not generating an Acknowledge bit on the last
byte that has been clocked out of the slave. In this case,

operations must be ended with a Stop condition.
