NOTES:
1. Refer to DC Characteristics When V
V
, memory contents can be read, but not altered.
2. X can be V
or V
IH
for control and address pins, and V
PENLK
or V
PENH
for V
PEN
. See DC Characteristics for V
PENLK
and V
voltages.
3. In default mode, STS is V
when the WSM is executing internal block erase, program, or lock-bit
configuration algorithms. It is V
when the WSM is not busy, in block erase suspend mode (with
programming inactive), program suspend mode, or reset/power-down mode.
4. See Read Identifier Codes Command section for read identifier code data.
5. See Read Query Mode Command section for read query data.
6. Command writes involving block erase, program, or lock-bit configuration are reliably executed when V
PEN
=
V
and V
is within specification.
7. Refer to Table 4 for valid D
during a write operation.
8. DQ refers to DQ
0–
DQ
if BYTE# is low and DQ
DQ
15
if BYTE# is high.
9. High Z will be V
with an external pull-up resistor.
10.See Table 2 for valid CE configurations.
11.OE# and WE# should never be enabled simultaneously.
