Mipi Spmi Specification Pdf

MIPI System Power Management Interface (SPMI) is a standardized bi-directional, two-wire serial interface designed to streamline power management in mobile and embedded systems. By connecting a System-on-Chip (SoC) processor to one or more Power Management Integrated Circuits (PMICs), SPMI allows for the dynamic monitoring and real-time control of supply voltages to optimize performance and battery life. Core Architecture and Features MIPI SPMI specification utilizes a simple physical layer consisting of two lines: (Serial Data) and
