AMI qualifies Renesas' I3C bus extension products AMI, a firmware and software solutions partner, has qualified Renesas Electronics' I3C bus extension products for its MegaRAC SP-X Remote Management Firmware. By having the I3C devices on AMIâs approved vendor list it makes any migration path much easier for customers shifting their DDR5 platforms and boards from I2C or other legacy expansion specifications to the new high-speed I3C specification. The IMX3102 2:1 bus multiplexer, IMX3112 1:2 bus expander, and DDR5 SPD Hub SPD5118 devices have been designed to provide design flexibility for engineers implementing I3C Basic as a system management bus for control plane designs across a variety of applications, including data centre and server applications, enterprise, factory automation, and communications equipment.
