Not all specifications are 100 percent tested. All Min/Max limits are guaranteed by Winbond via design,
electrical testing and/or characterization.
When different FS 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.
k = 1000.
