AT45DB081B
2225D–DFLSH–10/02
Note: 1. After power is applied and V
CC
is at the minimum specified datasheet value, the system should wait 20 ms before an opera-
tional mode is started.
Note: 1. I
cc1
during a buffer read is 20mA maximum.
Absolute Maximum Ratings*
Temperature under Bias ................................ -55°C to +125°C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.
Storage Temperature..................................... -65°C to +150°C
All Input Voltages
(including NC Pins)
with Respect to Ground...................................-0.6V to +6.25V
All Output Voltages
with Respect to Ground.............................-0.6V to V
