Notes:
1. D.C. stands for direct current. (
f
C = 0)
2. The
t
CH and
t
CL signal values must be greater than or equal to 1/
f
C.
3. Signal values are guaranteed by characterization, not 100% tested in production.
4. Signal clock rise and fall time values are expressed as a slew rate.
5. Signal values are only applicable as a constraint for a WRITE STATUS REGISTER command
when SRWD bit is set at 1.
6. V
PPH
should be kept at a valid level until the PROGRAM or ERASE operation has comple-
ted and its result (success or failure) is known.
