Serial Clock (C).
The serial clock provides the
timing of the serial interface. Instructions, ad-
dresses,ordatapresentat theinputpinarelatched
on the rising edge of the clockinput, while data on
theQ pinchangesafterthe fallingedgeof theclock
input.
Chip Select (S).
When S is high, the Memory is
deselectedand the Q output pin is at high imped-
ance and, unless an internal write operation is
underwaythe Memorywill be in thestandbypower
mode. S low enables the Memory, placingit in the
active power mode. It should be noted that after
power-on, a high to low transitionon S is required
prior to the startof any operation.
Write Protect (W).
This pin is for hardware write
protection. When W is low, writes to the Memory
aredisabledbutanyotheroperationsstayenabled.
WhenWishigh,all writesoperationsareavailable.
W going low at any time before the last bit D0 of
thedata streamwillresetthewriteenablelatchand
prevent programming. No action on W or on the
writeenable latchcan interrupta write cycle which
has commenced.
