6.3
Sequential Read
Sequential reads are initiated in the same way as a ran-
dom read except that after the 24C01SC/02SC trans-
mits the first data byte, the master issues an
acknowledge as opposed to a stop condition in a ran-
dom read. This directs the 24C01SC/02SC to transmit
the
next
sequentially
(Figure 6-3).
To provide sequential reads the 24C01SC/02SC con-
tains an internal address pointer which is incremented
by one at the completion of each operation. This
address pointer allows the entire memory contents to
be serially read during one operation.

Noise Protection
The 24C01SC/02SC employs a V
CC
threshold detector
circuit which disables the internal erase/write logic if the
V
CC
is below 1.5 volts at nominal conditions.
The SCL and SDA inputs have Schmitt trigger and filter
circuits which suppress noise spikes to assure proper
device operation even on a noisy bus.
