Power Name
Description
PLLA_VDD (1) PLL Power— The voltage (3.3 V) should be well-regulated and the input should be provided with
PLLP_VDD(1) an extremely low impedance path to the 3.3 VDD 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 VDD 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 VDD 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 VDD 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.
