AN47310 - PSoC® 1 Power Savings Using Sleep Mode

AN47310 introduces PSoC® 1 sleep mode operation and power-saving techniques. The topics include sleep mode basics, wakeup sources, power-saving techniques, and special sleep mode considerations. An example project that demonstrates sleep and wakeup operation is also provided.

​Introduction

Sleep mode is used to reduce a PSoC’s average current consumption by entering a low-power state, whenever the CPU and other internally clocked functions are not needed. Sleep mode is most useful for battery-powered systems, but it is applicable to any design.
