7.17 Power supply
The ISP1583 can be powered by 3.3 V
For connection details, see
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 V
are input type, the interrupt pin is connected to ground, and the suspend pin is connected
to V

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
