AT45DB021B

Note:

1. After power is applied and VCC is at the minimum specified datasheet value, the system should wait 20 ms before an

operational mode is started.

Note:

1. Icc1 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

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 VCC + 0.6V
