PMU is designed to supply embedded integrated circuits with stable and precise voltage and 1%-accurate clock frequency.
Overview
PMU is designed to supply embedded integrated circuits with stable and precise voltage and 1%-accurate clock frequency. It integrates 4 LDOs and 3 oscillators:
- “Always ON” LDO to supply circuits that are supposed to be always on;
- “Powered Down” LDO to supply digital circuits of “Powered Down” domain
- “Context Safe” LDO to supply digital circuits of “Context Safe” domain
- “Flash” LDO to supply flash memory
- 1.024 MHz oscillator
- 10 MHz oscillator
- 100 MHz oscillator
All LDOs have controllable output voltage level and are complemented with VDD detectors to monitor output voltage value. All LDOs may function in two modes: full power mode and ECO mode to save battery charge if high performance of the system is not required.
