Notes:

Write timing characteristics during erase suspend are the same as write-only operations.

A write operation can be terminated with either CE# or WE#.

Sampled, not 100% tested.

Write pulse width low (tWLWH or tELEH) is defined from CE# or WE# low (whichever occurs last) to

CE# or WE# high (whichever occurs first). Hence, tWLWH = tELEH = tWLEH = tELWH.

Write pulse width high (tWHWL or tEHEL) is defined from CE# or WE# high (whichever occurs first) to

CE# or WE# low (whichever occurs last). Hence, tWHWL = tEHEL = tWHEL = tEHWL).

WHVH or tWHCH/L must be met when transitioning from a write cycle to a synchronous burst read.

VPP and WP# should be at a valid level until erase or program success is determined.

This specification is only applicable when transitioning from a write cycle to an asynchronous read.

See spec W19 and W20 for synchronous read.

When doing a Read Status operation following any command that alters the Status Register, W14 is

20 ns.

10.

Add 10 ns if the write operations results in a RCR or block lock status change, for the subsequent

read operation to reflect this change.

11.

These specs are required only when the device is in a synchronous mode and clock is active during

address setup phase.
