12 Low-Power Improvements Core voltage scaling Like dynamic voltage and frequency scaling (DVFS) but for a microcontroller Permits lowering of core VDD in exchange for lower levels of performance Low-Energy Peripheral Power-Down Domains High-frequency peripherals are powered down in the lowest energy mode Now have the option to do for low-energy peripherals without recovery via reset 12

13 Series 1 Energy Modes Review Energy Mode EM0 (Run) EM1 (Sleep) EM2 (Deep Sleep) EM3 (Stop) EM4H (Hibernate) EM4S (Shutdown) CPU High-Frequency Peripherals Analog Peripherals Low-Frequency Peripherals Asynchronous Peripherals I/O & Interrupts Brown-Out Detectors On All All All All All On All All All All All On LDMA, LCD, I2C All All All All On LDMA, I2C All except CSEN LETIMER All All On Temp Sensor, DC-DC, VMON RTCC, CRYOTIMER CRYOTIMER All (Retained), Subset (Wake) All (Retained), Subset (Wake) On On 13

14 Core Voltage Scaling External DVDD supply is regulated down to some nominal voltage (e.g. 1.8V for 180 nm) Typically, core voltage remains constant regardless of clock frequency Voltage scaling permits lowering of core VDD in exchange for lower levels of performance Available in all energy modes: EM0 (core active) down to EM4 (hibernate or shutdown) Maximum Operating Frequency Series 0 Series 1 Standard Core VDD Scaled Core VDD 48 MHz 72 MHz 20 MHz 14

15 Series 0 Core Voltage Across Energy Modes Normal Core VDD EM0 EM1 EM2 EM3 EM4 Voltage for digital core logic is regulated from external supply Remains constant across all energy modes, regardless of peripheral utilization Current draw is reduced in each energy mode as clocks are stopped to peripheral blocks On Series 0, EM4 is shutdown mode with optional pin wake-up 15

16 Series 1 Internal Voltage Across Energy Modes Normal Core VDD Voltage for digital core logic is regulated from external supply Scaling permits core voltage level to be reduced upon transitions between energy modes EM0 EM1 Reduced Core VDD EM2 EM3 EM4H EM4S Typical use case would be to scale in EM2 and lower when high frequency peripherals are not needed (e.g. DMA) Greater reductions in current draw are achieved in low energy modes both because clocks are stopped and because core voltage is lowered 16
