Notes:
1.
Write timing characteristics during erase suspend are the same as write-only operations.
2.
A write operation can be terminated with either CE# or WE#.
3.
Sampled, not 100% tested.
4.
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, t
WLWH
= t
ELEH
= t
WLEH
= t
ELWH
.
5.
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 = tEHW).
6.
t
WHVH
or t
WHCH/L
must be met when transitioning from a write cycle to a synchronous burst read.
7.
VPP should be at a valid level until erase or program success is determined.
8.
This specification is only applicable when transitioning from a write cycle to an asynchronous read.
See specs W19 and W20 for synchronous read.
9.
When doing a Read Status operation following any command that alters the Status Register, W14 is
20 ns.
10.
Add 10ns if the write operation 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.
