DC CHARACTERISTICS

CMOS Compatible

Notes:

1. On the WP# pin only, the maximum input load current when WP# = V

IL is ± 5.0 µA.

2. The I

CC current listed is typically less than 2 mA/MHz, with OE# at VIH.

3. Maximum I

CC specifications are tested with VCC = VCCmax.

4. I

CC active while Embedded Erase or Embedded Program is in progress.

5. Automatic sleep mode enables the low power mode when addresses remain stable for t

ACC + 30 ns. Typical sleep mode current is

200 nA.

6. If V

IO < VCC, maximum VIL for CE# and DQ I/Os is 0.3 VIO. If VIO < VCC, minimum VIH for CE# and DQ I/Os is 0.7 VIO. Maximum VIH

for these connections is V

IO + 0.3 V

7. Not 100% tested.
