PRELIMINARY
Notes:
1. The I
CC
current listed is typically less than 2 mA/MHz, with OE# at
V
IH
.
2. Maximu m I
CC
specifications are tested with V
CC
= V
CC
max.
3. I
CC
active while Embedded Erase or Embedded Program is in
progress.
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.
