Maximum Ratings and Operating Conditions
Absolute Maximum Ratings
Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent
damage. These are stress ratings only.
Operating Conditions
Operation beyond the “Operating Conditions” is not recommended. Extended exposure
beyond the “Operating Conditions” may affect device reliability.
Power Supply
This section provides an overview of system-level considerations with regards to the
flash device. It includes a brief description of power-up, power-down and decoupling
design considerations.
Power-Up/Down Characteristics
The device is protected against accidental block erasure or programming during power
transitions. After power-up, a t
