NOTES:
1. Refer to Table 19. When V
PP
V
PPLK
, memory contents can be read, but not altered.
2. X can be V
IL
or V
IH
for control and address input pins and V
PPLK
or V
PPH1/2
for V
PP
. See Table 19, for V
PPLK
and V
PPH1/2
voltages.
3. STS in level RY/BY# mode (default) is V
OL
when the WSM is executing internal block erase, programming, or lock-bit
configuration algorithms. It is V
OH
when the WSM is not busy, in block erase suspend mode (with programming inactive),
program suspend mode, or deep power-down mode.
4. See Section 4.3 for read identifier code data.
5. See Section 4.2 for read query data.
6. Command writes involving block erase, write, or lock-bit configuration are reliably executed when V
PP
= V
PPH1/2
and
V
CC
= V
CC1/2
(see Section 6.2).
7. Refer to Table 3 for valid D
IN
during a write operation.
8. DQ refers to DQ
0
–7
if BYTE# is low and DQ
0–15
if BYTE# is high.
9. High Z will be V
OH
with an external pull-up resistor.
10.
RP# at GND ± 0.2V ensures the lowest deep power-down current.
11. OE# = V
IL
and WE# = V
IL
concurrently is an undefined state and should not be attempted.
