I3C Bus Extension and SPD Hub Devices for AMI Firmware

Renesas Electronics Corporation announced that AMI, a firmware and software solutions partner, has qualified the Renesas I3C bus extension products for its MegaRAC SP-X Remote Management Firmware. Having the I3C devices on AMI’s approved vendor list enables an easy migration path 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 provide maximum design flexibility for engineers implementing I3C Basic as a system management bus for control plane designs across a variety of applications, including data center and server applications, enterprise, factory automation, and communications equipment. The IMX and SPD devices are ideal when there may be multiple masters, a large number of endpoint devices, and long traces – all of which can impact bus complexity and signal integrity.

Renesas’ expanded I3C portfolio ecosystem enables both software and hardware customers to design in the Renesas IMX and SPD products with confidence. The I3C portfolio was previously qualified with hardware, Baseboard Management Controller (BMC), and other silicon-on-chip partners.

As DDR5 continues to gather momentum in the industry, the I3C interface is gaining acceptance as a high-speed control interface for applications requiring faster communication between host and peripheral or slave devices. I3C’s 12.5 MHz speeds significantly outpace current and legacy solutions, such as the I2C 1 MHz speed and analog passive quick switches. Renesas continues to be the I3C technology leader with a robust lineup of I3C bus extension devices for platform control, efficiency, power savings, high speeds, safety, and security.
