Unidirectional from the master to slaves. 2. Speed Classifications High Speed (HS): Up to 26 MHz. Low Speed (LS): Up to 15 MHz. 3. Arbitration
The SPMI specification is robust and designed for modern, high-performance environments. The latest specifications (v2.0/v3.0) offer enhanced features compared to earlier versions. mipi spmi specification pdf
While I2C and SPI are common, they are often insufficient for modern power management for several reasons: Unidirectional from the master to slaves
The (System Power Management Interface) is a standardized, high-speed, low-latency, two-wire serial interface designed for communication between a processor (typically the power controller in an SoC) and peripheral components, most notably Power Management Integrated Circuits (PMICs). Low Speed (LS): Up to 15 MHz
Fewer pins mean smaller PCB areas and reduced routing congestion.
The primary objective of SPMI is efficient energy distribution. The specification natively supports advanced power-saving protocols:
Includes built-in mechanisms to handle bus contention based on task urgency. Key Features of the MIPI SPMI Specification 1. High Performance and Low Latency
