Description
PLLA_VDD (1) PLL Power — The voltage (3.3 V) should be well-regulated and the input should be provided with an
PLLP_VDD(1)
extremely low impedance path to the 3.3 V DD power rail. The user must provide adequate external
decoupling capacitors.
PLLD_VDD (1) PLL Power— The voltage (1.25 V) should be well-regulated and the input should be provided with
an extremely low impedance path to the 1.25 V DD power rail. The user must provide adequate
external decoupling capacitors.
CORE_VDD (4) Core Power —The voltage (1.25 V) should be well-regulated and the input should be provided with
an extremely low impedance path to the 1.25 V DD power rail. The user must provide adequate
decoupling capacitors.
IO_VDD (5)
SHI, ESAI, ESAI_1, DAX and Timer I/O Power —The voltage (3.3 V) should be well-regulated and
the input should be provided with an extremely low impedance path to the 3.3 V DD power rail. This
is an isolated power for the SHI, ESAI, ESAI_1, DAX and Timer I/O. The user must provide adequate
external decoupling capacitors.
