7.3.2 LOW VOLTAGE DISTRIBUTION
All iPAQ systems produce voltages less than 3.3 VDC (including processor core (VccP) voltage)
through regulator circuitry on the system board.
An on-board regulator produces the VccP (processor core) voltage according to the strapping of
signals VID3..0 by the processor. The possible voltages available are listed as follows:
VID 3..0 VccP VID 3..0 VccP
0000 2.05 VDC 1000 1.65 VDC
0001 2.00 VDC 1001 1.60 VDC
0010 1.95 VDC 1010 1.55 VDC
0011 1.90 VDC 1011 1.50 VDC
0100 1.85 VDC 1100 1.45 VDC
0101 1.80 VDC 1101 1.40 VDC
0110 1.75 VDC 1110 1.35 VDC
0111 1.70 VDC 1111 1.30 VDC
