POWER SUPPLY SEQUENCING
internal 1.8 V regulator), the external 1.8 V power sup-
ply must be energized before the 3.3 V supply. Other-
wise, the 1.8 V supply may not lag the 3.3 V supply by
more than 10 µs.
ence between the two power supplies must be within
1.5 V during power supply ramp up.

powered-on as described above.
LINEAR REGULATOR
using its output to power external devices is not recom-
mended. External loads can affect the regulator’s sta-
bility and introduce noise into the supply. SHARP

PERIPHERAL CURRENT CONSUMPTION
27 shows the typical current consumption for each of
the on-board peripheral blocks. The values were deter-
mined with the peripheral clock running at maximum
frequency, typical conditions, and no I/O loads. This
current is supplied by the 1.8 V power supply.
