Serial Clock (C).
The serial clock provides the
timing of the serial interface. Instructions, ad-
dresses, or data present at the input pin are latched
on the rising edge of the clock input, while data on
the Q pin changes after the falling edge of the clock
input.
Chip Select (S).
When S is high, the Memory is
deselected and the Q output pin is at high imped-
ance and, unless an internal write operation is
underway the Memory will be in the standby power
mode. S low enables the Memory, placing it in the
active power mode. For a safe design, it should be
noted that during power up, the S input must be
driven constantly high (or low) but must NOT be left
floating until the supplied voltage reaches the
specified V
CC
value. After power up, a high to low
transition on S is required prior to the start of any
operation.
Write Protect (W).
This pin is for hardware write
protection. When W is low, writes to the Memory
are disabled but any other operations stay enabled.
When W is high, all writes operations are available.
W going low at any time before the last bit D0 of
the data stream will reset the write enable latch and
prevent programming. No action on W or on the
write enable latch can interrupt a write cycle which
has commenced.
