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, tWLWH = tELEH = tWLEH = tELWH.
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 = tEHWL).
6.
tWHVH or tWHCH/L must be met when transiting from a write cycle to a synchronous burst read.
7.
VPP and WP# should be at a valid level until erase or program success is determined.
8.
This specification is only applicable when transiting from a write cycle to an asynchronous read. See spec W19 and W20
for synchronous read.
9.
When doing a Read Status operation following any command that alters the Status Register, W14 is 20ns.
10.
Add 10ns 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.
12.
This specification must be complied with by customer’s writing timing. The result would be unpredictable if any violation
to this timing specification.
