DDR5 I3C bus extension and SPD hub devices qualified for partner firmware Renesas Electronics Corporation has announced that AMI has qualified the Renesas I3C bus extension products for its MegaRAC SP-X Remote Management Firmware. Having the I3C devices on its approved vendor list allows an easy migration path for customers moving 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 offer maximum design flexibility for engineers implementing I3C Basic as a system management bus for control plane designs over a mixture of applications, including data centre and server applications, factory automation, enterprise, and communications equipment. The devices are excellent when there can be multiple masters, a large number of endpoint devices, and long traces – all of which can impact bus complexity and signal integrity.
