NOTES:
1. Refer to DC Characteristics. When V
CCW
V
CCWLK
, memory contents can be read, but not altered.
2. X can be V
IL
or V
IH
for control pins and addresses, and V
CCWLK
or V
CCWH1/2
for V
CCW
. See DC Characteristics for
V
CCWLK
voltages.
3. RY/BY# is V
OL
when the WSM is executing internal block erase, full chip erase, word/byte write or lock-bit configuration
algorithms. It is High Z during when the WSM is not busy, in block erase suspend mode (with word/byte write inactive),
word/byte write suspend mode or reset mode.
4. RP# at GND±0.2V ensures the lowest power consumption.
5. See Section 4.2 for read identifier code data.
6. Command writes involving block erase, full chip erase, word/byte write or lock-bit configuration are reliably executed
when V

=V
CCWH1/2
and V
CC
=2.7V-3.6V.
7. Refer to Table 3 for valid D
IN
during a write operation.
8. Never hold OE# low and WE# low at the same timing.
