I3C Hub 2:4 Intelligent Switch (Pre-configured)

RG3M48B12 is a 2:4 intelligent switch with downstream ports default enabled.

The RG3MxxB12B1 is a family of I2C/I3C multiple port hub devices featuring two I2C/I3C Master Side ports and up to eight I2C/IC Slave Side ports. This hub device provides connectivity to up to two masters, and up to eight slaves. By cascading and duplicating the RG3MxxB12B1, the user builds an RG3MxxB12B1 hub network to provide connectivity to several devices, with extended reach distance, and running with different levels of I2C, I3C, and SMBus protocols.

In an RG3MxxB12B1 device, each Master Side port is associated with an on-chip I2C/I3C slave interface. Each I2C/I3C interface accesses on-chip registers. Master-Master communication is achieved with shared registers and intra-port IBI channels.
