PMU (Power Management Unit)
3.4.1
Features and Overview
The Power Management Unit (referred to as “PMU” hereinafter) is the block that performs overall power supply
control of the CXD5602.
The CXD5602 has a large power domain, which is divided into 11 domains. It performs ON control of necessary
power domains only, while performing OFF control of the unnecessary ones, thereby reducing the power
consumption.
The 11 power domains comprise a layer structure as shown in Figure PMU (Power Management Unit)-26. The
lower-layer power domains cannot be turned ON when the upper-layer power supplies are OFF. Furthermore,
PWD_GNSS can be turned ON only when both PWD_GNSS_ITP and PWD_SYSIOP are ON.
