Low-power operation is essential for IoT endpoint devices which might rely on a battery or on harvested energy. SSE-200 uses two key methods to reduce the overall power of the system:
Each power domain contains a Power Integration Kit (PIK) that performs the following:
The PIK of each domain is primarily designed to deal with the power control of its associated power domain. However, some power domains are aware of the power state of other power domains, to maintain the correct operation of the system. The Power Dependency Control Matrix (PDCM) enables software to configure the relationship between each power domain.
