PSoC 4 supports four low power modes as shown in the table: Sleep, Deep-Sleep, Hibernate and Stop. PSoC 4 has the lowest-leakage process technology which consumes the lowest current and stop mode with GPIO state retention, retains SRAM and UDB state in Hibernate mode, and provides full state retention in Deep Sleep mode with LCD Operation. PSoC Creator’s APIs simplify power management by enabling changes between power modes and by controlling the power of individual PSoC components.
