ISP1582
Hi-Speed USB peripheral controller
Table 6 shows power modes in which the ISP1582 can be operated.
[1]
The power supply to the IC (VCC) is 3.3 V. Therefore, if the application is bus-powered, a 3.3 V regulator
must be used.
[2]
VCC(I/O) = VCC. If the application is bus-powered, a voltage regulator must be used.
(1) At the VCC input (3.3 V) to the USB controller, if the ripple voltage is less than 20 mV, then 4.7 F
standard electrolytic or tantalum capacitors (tested ESR up to 10
) should be OK at the VCC1V8
output. If the ripple voltage at the input is higher than 20 mV, then use 4.7
F LOW ESR capacitors
(ESR from 0.2
to 2 ) at the VCC1V8 output. This is to improve the high-speed signal quality at
the USB side.
