Device Operation
CLOCK and DATA TRANSITIONS:
The
S
DA pin is norm
a
lly pulled high with
a
n exter-
n
a
l device. D
a
t
a
on the
S
DA pin m
a
y ch
a
nge only during
S
CL low time periods (see
Figure 4 on p
a
ge 7). D
a
t
a
ch
a
nges during
S
CL high periods will indic
a
te
a
st
a
rt or stop
condition
a
s defined

elow.
START CONDITION:
A high-to-low tr
a
nsition of
S
DA with
S
CL high is
a
st
a
rt condition
which must precede
a
ny other comm
a
nd (see Figure 5 on p
a
ge
8
).
STOP CONDITION:
A low-to-high tr
a
nsition of
S
DA with
S
CL high is
a
stop condition.
After
a
re
a
d sequence, the stop comm
a
nd will pl
a
ce the EEPROM in
a
st
a
nd
b
y power
mode (see Figure 5 on p
a
ge
8
).
ACKNOWLEDGE:
All
a
ddresses
a
nd d
a
t
a
words
a
re seri
a
lly tr
a
nsmitted to
a
nd from the
EEPROM in
8
-
b
it words. The EEPROM sends
a
zero to
a
cknowledge th
a
t it h
a
s
received e
a
ch word. This h
a
ppens during the ninth clock cycle.
STANDBY MODE:
The AT24C01B fe
a
tures
a
low-power st
a
nd
b
y mode which is
