Power-On Reset (POR) Description
The SY89464U includes an internal power-on reset
(POR) function to ensure the RPE logic starts-up in a
known logic state once the power-supply voltage is
stable. An external capacitor connected between VCC
and the CAP pin (pin 12) controls the delay for the
power-on reset function.
The required capacitor value calculation is based upon
the time the system power supply needs to power up
to a minimum of 2.3V. The time constant for the
internal power-on-reset must be greater than the time
required for the power supply to ramp up to a minimum
of 2.3V.
The following formula describes this relationship:
C(
F) ≥
t
dPS(m s)
12(ms/
F)
As an example, if the time required for the system
power supply to power up past 2.3V is 12ms, then the
required capacitor value on pin 12 would be:
C(
F) ≥
12ms
12(ms/
F)
C(F)
≥ 1F
