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.

(max), where N

= number of bytes programmed.
