Not all specifications are 100 percent tested. All Min/Max limits are guaranteed by Winbond via design,

electrical testing and/or characterization.

[3]

When different F

S

is applied, the value will change accordingly. Also, stability of internal oscillator may

vary as much as +10% over the operating temperature and voltage ranges.
