Note 1: All voltages are referenced to ground.
Note 2: This is the absolute accuracy of the master oscillator frequency at the default settings with spread disabled.
Note 3: This is the change that is observed in master oscillator frequency with changes in voltage at T
Note 4: This is the change that is observed in master oscillator frequency with changes in temperature at V
Note 5: The dither deviation of the master oscillator frequency is biderectional and results in an output frequency centered at the
Note 6: This indicates the time elapsed between power-up and the output becoming active. An on-chip delay is intentionally intro-
Note 7: Timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I
Note 8: C B —total capacitance of one bus line in picofarads.
Note 9: EEPROM write time applies to all the EEPROM memory and SRAM shadowed EEPROM memory when WC = 0.
Note 10: Typical frequency shift due to aging is ±0.25%. Aging stressing includes Level 1 moisture reflow conditioning (24hr) +125°C
