Note: The value in the left hand column shows the formula used to calculate the timing minimum or maximum from the oscillator clock period.

The value in the right hand two columns show the timing minimum and maximum for an internal clock at 24MHz (INTCLK).

(1) 3.0 - 4.0V voltage range is only available on devices with suffix L or V, with different frequency limitatio ns (L: 8 MHz, V: 16 MHz)

(2) Formula guaranteed by design.

Legend:

Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;

2 x OSCIN period when OSCIN is divided by 2;

OSCIN period x PLL factor when the PLL is enabled.
