±
5%, V
=0V, T
=–40 to 85
°
C).
Typical figures are at 25

NOTE:
The write cycle can be initiated either by the falling edge ofCS or the rising edge of E clock whichever occurs last. Similarly
the cycle can be terminated by CS (rising edge) or E clock (falling edge) whichever occurs first. The timing relations are to be
referenced from the active edge initiating or terminating the cycle
