Table 17.9 lists the control signal timing and table 17.10 lists the serial interface timing.
Table 17.9 Control Signal Timing
One of following conditions is applied unless otherwise specified.
Condition A (F-ZTAT version): V_CC = 2.7 V to 3.6 V, AV_CC = 2.7 V to 3.6 V,
V_SS = AV_SS = 0.0 V
Condition B (F-ZTAT version): V_CC = 2.2 V to 3.6 V, AV_CC = 2.2 V to 3.6 V,
V_SS = AV_SS = 0.0 V
Condition C (Mask ROM version): V_CC = 1.8 V to 3.6 V, AV_CC = 1.8 V to 3.6 V,
V_SS = AV_SS = 0.0 V
