low-power (suspended) state level. Both the VP and VM pins are driven HIGH to
indicate this mode. Pin RCV is made LOW. Some hysteresis is built into the detection
of Vreg(3.3) lost.

7.4 Power supply input options
The ISP1105/1106/1107 range has two power supply input options:
Internal regulator — VCC(5.0) is connected to 4.0 to 5.5 V. The internal regulator is
used to supply the internal circuitry with 3.3 V (nominal). The Vreg(3.3) pin becomes a
3.3 V output reference.
Regulator bypass — VCC(5.0) and Vreg(3.3) are connected to the same supply. The
internal regulator is bypassed and the internal circuitry is supplied directly from the
Vreg(3.3) power supply. The voltage range is 3.0 to 3.6 V to comply with the USB
specification.
The supply voltage range for each input option is specified in Table 10.
