• PGOOD – This signal indicates the state of the onboard VIO supply for the IWR device coming from
the onboard PMIC. A high on the PGOOD signal (3.3 V) indicates that the supply is stable. Because
the IOs are not failsafe, the MCU must ensure that it does not drive any IO signals to the IWR device
before this IO supply is stable. Otherwise, there could be leakage current into the IOs.
• PMIC Enable – This signal goes onboard PMIC enable. The MCU can use this signal to completely
shut down the PMIC and IWR device to save power. The power up of the PMIC takes approximately 5
ms once the Enable signal is released.
NOTE: To enable this feature, the R102 resister must be populated on the EVM.
• ANA1/2/3/4 – These are inputs to the GPADCs (general purpose ADC) available on the IWR1443
device.
