DESCRIPTION
1.8 V from internal core regulator.
Both pins must be connected
together externally and then tied to a
10uF 0.1-Ohm ESR capacitor, in
parallel with a 0.01uF capacitor to
Ground next to each pin. These pins
must not be used to supply power to
other external devices. See
Ground for internal digital logic
1.8V Power from the internal PLL
regulator. This external pin must be
connected to a 10uF 0.1-Ohm ESR
capacitor, in parallel with a 0.01uF
capacitor to Ground. This pin must
not be used to supply power to other
external devices. See
