LPC11U1x
32-bit ARM Cortex-M0 microcontroller
on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic
power use in any peripherals that are not required for the application. Selected
peripherals have their own clock divider which provides even better power control.
7.13.5.1
Power profiles
The power consumption in Active and Sleep modes can be optimized for the application
through simple calls to the power profile. The power configuration routine configures the
LPC11U1x for one of the following power modes:
Default mode corresponding to power configuration after reset.
CPU performance mode corresponding to optimized processing capability.
Efficiency mode corresponding to optimized balance of current consumption and CPU
performance.
Low-current mode corresponding to lowest power consumption.
In addition, the power profile includes routines to select the optimal PLL settings for a
given system clock and PLL input clock.
7.13.5.2
Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence but re-enabling the clock to the ARM core.
In Sleep mode, execution of instructions is suspended until either a reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
7.13.5.3
Deep-sleep mode
In Deep-sleep mode, the LPC11U1x is in Sleep-mode and all peripheral clocks and all
clock sources are off with the exception of the IRC. The IRC output is disabled unless the
IRC is selected as input to the watchdog timer. In addition all analog blocks are shut down
and the flash is in stand-by mode. In Deep-sleep mode, the user has the option to keep
the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD
protection.
The LPC11U1x can wake up from Deep-sleep mode via reset, selected GPIO pins, a
watchdog timer interrupt, or an interrupt generating USB port activity.
Deep-sleep mode saves power and allows for short wake-up times.
7.13.5.4
Power-down mode
In Power-down mode, the LPC11U1x is in Sleep-mode and all peripheral clocks and all
clock sources are off with the exception of watchdog oscillator if selected. In addition all
analog blocks and the flash are shut down. In Power-down mode, the user has the option
to keep the BOD circuit running for BOD protection.
The LPC11U1x can wake up from Power-down mode via reset, selected GPIO pins, a
watchdog timer interrupt, or an interrupt generating USB port activity.
Power-down mode reduces power consumption compared to Deep-sleep mode at the
expense of longer wake-up times.
