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.
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.

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.

Application Note
also shows that some PSoC™ 4 MCU devices do not support all five power modes.
