System clock (fSYS):

?  Built in high-frequency 16MHz oscillator (fHRC)

?  When used as a system clock source, fSYS can be set to 16/8/4/1.33MHz through a programmer selection

?  Frequency error: Across (2.9V~5.5V) and (-10~85 ℃) application environments, not exceeding ± 1 PERCENT

?  Built in high-frequency crystal oscillator circuit

?  Can be connected to an external 2~16MHz oscillator

?  When used as a system clock source, fSYS can be programmed to choose one of the four frequency divisions: external crystal oscillator/1/2/4/12

?  The operating voltage range corresponding to the IC system clock (fSYS)

? > 12MHz @2.9~5.5V

? ≤ 12MHz @2.4~5.5V

Built in low-frequency 128kHz LRC oscillator:

?  Can serve as a clock source for Base Timer and wake up STOP
