Question: How should the RESET pin be configurated on the CY7C65640B/30/20?

 

Answer:

The reset pin should be configured to be a valid low signal (≤ 0.8 volts) for at least 1.9 msec.It is normally tied to VCC through a 100K resistor, and to GND through a 0.1-μF capacitor

This requirement comes from several items. The first requirement is the startup time of the crystal. This time period depends on the crystal and can consume up to 1.7 msec. Typically, most crystals will require around 1 msec. Once the oscillations have started an additional 200 usec is required to initialize the CY7C65640B, CY7C65630 or CY7C65620. After the reset is released the hub will delay USB function for an additional 3 msec. This, period is to give the crystal enough time to stabilize its frequency of oscillation.
