= 3.3 V ± 0.3 V, T

= -20°C to +70°C
NOTES:
1. All currents are in RMS unless otherwise noted. Typical values at V
CC
= 3.3 V, V
PP
= 5.0 V, T = 25°C.
2. I
CCES
is specified with the device de-selected. If the device is read while in erase suspend mode, current draw is the sum of
I
CCES
and I
CCR
.
3. Automatic Power Saving (APS) reduces I
CCR
to less than 2 mA in Static operation.
4. CMOS inputs are either V
CC
± 0.2 V or GND ± 0.2 V. TTL Inputs are either V
IL
or V
IH
.
5. These are the values of the current which is consumed within one bank area. The value for the bank0 and bank1 should be added in
order to calculate the value for the whole chip. If the bank0 is in write state and bank1 is in read state, the I
CC
= I
CCW
+ I
CCR
. If both
banks are in standby mode, the value for the device is 2 times the value in the above table.
