Renesas Electronics Company unveiled the business’s first I3C clever swap gadgets focusing on subsequent era server motherboards and different infrastructure gear. The brand new chips vastly improve scalability and reliability whereas lowering the complexity of high-performance system designs. They allow I3C management aircraft networks with a number of initiator controllers, reminiscent of CPU and Baseboard Administration Controllers (BMC), to help targets throughout a big bodily community working at full pace by enhancing sign integrity and lowering capacitive loading. Additionally they help heterogeneous designs by offering IO stage shifting and protocol translation for combined I2C/SMBus and I3C networks.
The MIPI I3C bus is a scalable management bus interface for connecting peripherals to processor or different administration controllers. It gives benefits of excessive efficiency, improved reliability, very low energy, and low electromagnetic interference (EMI). All of those advantages allow new system performance reminiscent of superior telemetry, fault restoration, sideband safety, element authentication and sooner boot instances.
Present system designs typically use the legacy I2C protocol and easy field-effect transistor (FET) switches to attach initiator and goal gadgets on a motherboard. This method can not scale to I3C speeds, which essentially limits system administration to essentially the most rudimentary of capabilities. Renesas’ new I3C clever swap household permits growth of two initiator (upstream) ports to 4, eight or extra goal ports at max pace with full protocol consciousness and compliance. The brand new Renesas household additionally supplies seamless translation between I3C and I2C gadgets permitting full plug and play compatibility of legacy gadgets onto the management aircraft community. The I3C Clever swap is a results of shut collaboration between Renesas and Intel groups beginning with conception, specification definition and different pre silicon actions. The collaboration continued to publish silicon actions together with software program improvement and element and system stage validation.
“Renesas was the pioneer of I3C hubs and expanders focusing on the DDR5 DIMM market and we’ve at all times imagined nice potential for this know-how to proliferate throughout all the platform,” stated Rami Sethi, Vice President and Basic Supervisor, Infrastructure Combined Sign Division at Renesas. “We’re thrilled to have labored with Intel to understand that imaginative and prescient with the introduction of our new I3C clever swap household. These gadgets empower our clients and companions to deliver superior platform administration capabilities to each subsystem inside the rack.”
“We’re happy on the robust collaboration between Renesas and Intel in defining an important circuit resolution for the increasing use instances of MIPI I3C Primary purposes,” stated Vik Tymchenko, VP and GM Platform {Hardware} Engineering Division at Intel. “Merchandise just like the I3C clever swap household assist clear up the elemental limitations of MIPI I3C interface implementations in information heart {hardware}. With an I3C swap we will improve capacitance and gadgets supported by an I3C community.”
Renesas is a world chief in high-performance computing peripheral gadgets. The brand new I3C clever swap household enhances Renesas options such because the DDR5 I3C expanders, registered clock drivers (RCDs), energy administration ICs (PMICs), serial presence detect (SPD) hubs, temperature sensors and information buffers.
