ISP1583

Hi-Speed USB peripheral controller

If the ISP1583 is powered by VCC(3V3) = 3.3 V, an integrated 3.3 V-to-1.8 V voltage

regulator provides a 1.8 V supply voltage for the internal logic.

In sharing mode (that is, when VCC(3.3) is not present and VCC(I/O) is present), all the

I/O pins are in 3-state, the interrupt pin is connected to ground, and the suspend pin

is connected to VCC(I/O). See Table 4.

[1] The power supply to the IC (VCC(3V3)) is 3.3 V. Therefore, if the application is bus-powered, a 3.3 V

regulator needs to be used.

[2] VCC(I/O) can range from 1.65 V to 3.6 V. If the application is bus-powered, a voltage regulator needs to

be used.
