Notes:
1.
The I
CC
current listed is typically less than 2 mA/MHz, with OE# at
V
IH
.
Maximum I
CC
specifications are tested with V
CC
= V
CC
max.
I
active while Embedded Erase or Embedded Program is in
progress.
2.
3.
4.
Automatic sleep mode enables the low power mode when
addresses remain stable for t
ACC
+ 30 ns. Typical sleep mode
current is 200 nA.
5.
Not 100% tested.
6.
CE#f refers to chip enable input of active flash (device being
addressed).
7.
Typical and maximum current specifications shown are for each
flash device.
