Notes:

Typical values measured at TA = +25 °C and nominal voltages. Assumes corresponding lock-bits are not set. Subject to

change based on device characterization.

These performance numbers are valid for all speed versions.

Sampled but not 100% tested.

Excludes system-level overhead.

These values are valid when the buffer is full, and the start address is aligned.

Max values are measured at worst case temperature, data pattern and VCC corner within 100K cycles. But for W650, W651,

W600 and W601, the Max value are expressed at +25 °C or -40 °C.

W602 is the typical time between an initial block erase or erase resume command and then a subsequent erase suspend

command. Violating the specification repeatedly during any particular block erase may cause erase failures.
