General Description
The System Management Bus (SMBus) and Power Management Bus (PMBus) Slave component provides a simple way to add an I2C physical layer interface to a PSoC 3 or PSoC 5 design with either SMBus or PMBus protocol running on top of it.
The SMBus is a two-wire interface with various System Management chips that can communicate with the system host. It uses I2C as a physical layer. The SMBus Slave component implements most of the SMBus Slave device specifications and provides options for configuring the slave device parameters. The slave device can communicate with the SMBus Master using the provided APIs.
The PMBus protocol is a specific implementation of the more generic SMBus protocol. With the PMBus, the component presents all the possible PMBus commands and allows you to select which commands are relevant to your application.
Required Software: PSoC Creator 2.1 Component Pack 4 and above.
