PSoC™ 4 MCU low -power modes and power reduction techniques
Power mode summary
2 Power mode summary
PSoC™ 4 MCU features up to five power modes of operation. In order of power consumption and functionality,
they are: active, sleep, deep sleep, hibernate, and stop. Table 1 lists the typical current and wakeup times for
each power mode. See the product line datasheet for other values and specific conditions.
•
Active mode is the normal operating mode in which all peripherals are available, and the CPU is executing
instructions.
•
In sleep mode, all peripherals except the CPU are available.
•
In deep sleep mode, the CPU, most peripherals, and the MHz clocks are disabled.
•
In hibernate mode, no clocks are available, but logical states are retained.
•
In stop mode, the CPU, clocks, and all peripherals are halted, and logical states are not retained, but GPIO
states are retained or frozen.
Note: Table 1 also shows that some PSoC™ 4 MCU devices do not support all five power modes.

The differences among the low-power modes are related to CPU and peripheral availability, wakeup and reset
sources, power mode transition behaviors, and power consumption.
Table 2 shows the PSoC™ 4 MCU
resources and their availability in different power modes.
