8.14 Power supply

The ISP1582 can be powered by 3.3 V ± 0.3 V, and 3.3 V at the interface. For

connection details, see Figure 11.

If the ISP1582 is powered by VCC = 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 is not present and VCC(I/O) is present), all the I/O

pins are in three-state, the interrupt pin is connected to ground, and the suspend pin

is connected to VCC(I/O). See Table 3.
