Type Description
I SDIO I/O supply (1.8V to 3.3V)
I VDDIO_SD should be supplied externally if the SDIO
interface is used.
Even if the SDIO interface is not used, VDDIO_SD should
not be grounded (instead, the PALDO output can be used
for VDDIO_SD. Alternately VDDIO_SD can use the same
supply as VDDIO).
I RF I/O supply (2.6V to 3.3V)
I VDDIO_RF should be supplied externally (it cannot be
supplied from the PALDO) when the RF front-end is shared
with other devices, such as Bluetooth. The same external
supply should be used for pulls-ups, because PALDO is
shutdown during sleep mode and when the BCM4319 is
powered down.
I Digital I/O supply (1.8V to 3.3V)
