Power profiles
On the Cortex-M0 LPC1100XL series, the ROM includes API-driven
power profiles that let designers work with ready-to-use power
management templates. The power profiles can be customized for
any low-power application, so designers can reach ideal power levels
with minimal application intervention. The power profiles serve as
an excellent alternative to non-configurable low-power modes, since
they can conduct dynamic power management and optimize CPU
operation for various application states. This minimizes overall energy
consumption while maintaining the lowest operating current at low
supply voltages. Optimized for CPU performance, CPU efficiency, and
lowest active current, the power profiles enable maximum operating
frequency through the entire voltage range from 1.8 to 3.6 V without
compromising speed or functionality. The designer can also change
the system clock frequency dynamically, without the overhead
required to configure any system PLLs.
