Bidirectional mode. Upon power-up, the device will be

in the Transmit-Only mode, sending a serial bit stream
of the memory array from 00h to 7Fh, clocked by the
VCLK pin. A valid high-to-low transition on the SCL
pin will cause the device to enter the Transition mode
and look for a valid control byte on the I 2 C bus. If it
detects a valid control byte from the master, it will
switch into Bidirectional mode, with byte selectable

If no control byte is received, the device will revert to
the Transmit-Only mode after it receives 128 consec-
utive VCLK pulses while the SCL pin is idle. The
24LCS21A also enables the user to write-protect the
entire memory array using its write-protect pin. The
24LCS21A is available in a standard 8-pin PDIP and
SOIC package in industrial temperature range.
