Mipi Spmi Specification Pdf |top| Online

The MIPI System Power Management Interface (MIPI SPMI℠) is a bidirectional, two-wire serial interface designed to manage power in mobile and embedded systems. It standardizes communication between a system-on-chip (SoC) processor’s power controller and power management integrated circuits (PMICs) to enable real-time control of supply voltages and performance levels.

• Arbitration: How multiple masters compete for the bus without corrupting data. The spec uses a wired-AND mechanism similar to I2C but with unique SPMI priority rules.
