The Intel(R) Innovation Platform Framework SMBUS Device driver refers to a component of Intel's Platform Innovation Framework (PIE), which is used to support system management features, particularly those related to the System Management Bus (SMBus). This driver typically manages communication between the SMBus controller and various components of your system, such as sensors, power management devices, and thermal monitoring equipment.

The SMBus is a two-wire communication protocol often used in systems for managing hardware health monitoring and power management. The Intel(R) Innovation Platform Framework SMBUS Device driver facilitates this communication and allows Windows to interact with hardware components such as temperature sensors, fan controllers, battery management, and more.
