DDR5 I3C bus extension and SPD hub devices qualified for partner firmware

05-05-2021 | Renesas | Semiconductors

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.


The company’s expanded I3C portfolio ecosystem enables both software and hardware customers to design in its IMX and SPD products confidently. The I3C portfolio was previously qualified with hardware, Baseboard Management Controller, and other silicon-on-chip partners.


“Industry transformations such as the migration of control plane designs to the faster and more robust I3C standard require broad ecosystem support at both hardware and software levels to be successful,” said Rami Sethi, vice president and general manager of the Data Center Business Division at Renesas. “Partnering with industry-leading software providers like AMI has been a priority at Renesas to deliver the superior “out-of-the-box” experience that our customers and ecosystem partners have come to expect from us.”


“The next-generation I3C interface meets industry needs driven by aggressive data centre growth and increased demand for security infrastructure and more efficient hardware in industrial, automotive, and telecommunications systems. AMI is proud to qualify these latest DDR5 I3C Bus Extension and SPD Hub Devices from Renesas in its MegaRAC SP-X Remote Management Firmware,” said Kelly Bryant, chief product officer at AMI. “AMI has an extensive, industry-leading boot and manageability firmware ecosystem that supports many components, and for many years, top manufacturers such as Renesas have seen the value in qualifying their products for our firmware solutions. Thanks to our strong partnership with Renesas, our validation for its latest, leading-edge I3C expansion and SPD products will enable us to deliver improved firmware and software solutions and expand our support to our mutual customers.”
