11. Power Modes
The PSoC
®
4 provides three power modes, intended to minimize the average power consumption for a given application. The
power modes, in the order of decreasing power consumption, are:
■ Active
■ Sleep
■ Deep-Sleep
Active, Sleep, and Deep-Sleep are standard ARM-defined power modes, supported by the ARM CPUs and instruction set
architecture (ISA).
The power consumption in different power modes is controlled by using the following methods:
■ Enabling/disabling peripherals
■ Powering on/off internal regulators
■ Powering on/off clock sources
■ Powering on/off other portions of the PSoC 4
Figure 11-1 illustrates the various power modes and the possible transitions between them.
