Notes:
1.
Clock high + Clock low must be less than or equal to 1/f
C
.
2.
Value guaranteed by design and/or characterization, not 100% tested in production.
3.
Only applicable as a constraint for a Write Status Register instruction when Sector Protect Bit is set to 1.
4.
Commercial temperature only applies to Fast Read (F
R0
& F
R1
). Industrial temperature applies to all other parameters.
5.
