Notes:
1. Refer to DC Characteristics. When V
PP
≤
V
PPLK
, memory contents can be read, but not altered.
2. X can be V
IL
or V
IH
for control pins and addresses, and V

or V

. See DC Characteristics for V

voltages.
3. RY/#BY is V
when the WSM is executing internal block erase or word/byte write algorithms. It is V
during when the WSM
is not busy, in block erase suspend mode (with word/byte write inactive), word/byte write suspend mode or deep power-down
mode.
4. #RESET at V
SS
±
0.2V ensures the lowest deep power-down current.
5. See Read Identifier Codes Command section for details.
6. Command writes involving block erase or word/byte write are reliably executed when V
PP
= V
PPH1/2/3
and V
DD
= V
DD1/2/3/4
. Block
erase or word/byte write with V
IH
< #RESET < V
HH
produce spurious results and should not be attempted.
7. Refer to Table 4 for valid DIN during a write operation.
8. Never hold #OE low and #WE low at the same timing.
9. A-1 set to V
IL
or V
IH
in byte mode (#BYTE = V
IL
).
10. #WP set to V
