Up to (e.g., Application Processor, Modem, GPU).
I’ve been reviewing the latest , and it remains a cornerstone for connecting power management ICs (PMICs) with application processors.
The core objective of SPMI is efficient power management. The specification incorporates several features specifically designed to facilitate Dynamic Voltage and Frequency Scaling (DVFS). High-Speed Register Access mipi spmi specification pdf
The MIPI SPMI specification defines a high-speed, low-power interface for power management in SoC designs. The interface is designed to be scalable, flexible, and efficient, allowing for the management of multiple power domains and voltage regulators.
Up to (e.g., Primary PMIC, Secondary PMIC, Audio Codec, RF Transceiver).
The SPMI bus operates on a master-slave architecture but introduces advanced arbitration to support multiple master devices. The Two-Wire Interface Here are the facts about accessing this document
