ST92163 - ELECTRICAL CHARACTERISTICS
EXTERNAL BUS TIMING TABLE
(V
Note: The value in the left hand column shows the formula used to calculate the timing minimum or maximum from the oscillator clock period,
prescaler value and number of wait cycles inserted.
The values in the right hand two columns show the timing minimum and maximum for an external clock at 24MHz, prescaler value of zero
and zero wait states.
(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)
Legend:
Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2;
TckH = INTCLK high pulse width (normally = Tck/2, except when INTCLK = OSCIN, in which case it is OSCIN high pulse width)
TckL = INTCLK low pulse width (normally = Tck/2, except when INTCLK = OSCIN, in which case it is OSCIN low pulse width)
P = clock prescaling value (=PRS; division factor = 1+P)
Wa = wait cycles on AS; = max (P, programmed wait cycles in EMR2, requested wait cycles with WAIT)
Wd = wait cycles on DS; = max (P, programmed wait cycles in WCR, requested wait cycles with WAIT)
