Highly effective DDR5 I3C Bus Extension and SPD Hub Gadgets


Expanded I3C ecosystem now contains firmware, software program and {hardware}, accelerating product qualification and adoption for DDR5 options

As DDR5 continues to assemble momentum within the business, the I3C interface is gaining acceptance as a high-speed management interface for functions requiring quicker communication between host and peripheral or slave units. I3C’s 12.5 MHz speeds considerably outpace present and legacy options, such because the I2C 1 MHz pace and analogue passive fast switches.

For this, Renesas Electronics’ IMX3102 2:1 bus multiplexer, IMX3112 1:2 bus expander, and DDR5 SPD Hub SPD5118 units present most design flexibility for engineers implementing I3C Fundamental as a system administration bus for management aircraft designs throughout quite a lot of functions, together with information centre and server functions, enterprise, manufacturing facility automation, and communications gear. The IMX and SPD units are excellent when there could also be a number of masters, numerous endpoint units, and lengthy traces – all of which might impression bus complexity and sign integrity.

The expanded I3C portfolio ecosystem allows each software program and {hardware} prospects to design within the Renesas IMX and SPD merchandise with confidence.

“Business transformations such because the migration of management aircraft designs to the quicker and extra sturdy I3C customary require broad ecosystem help at each {hardware} and software program ranges to achieve success,” stated Rami Sethi, Vice President and Basic Supervisor of the Knowledge Middle Enterprise Division at Renesas.

Just lately, AMI, a firmware and software program options companion, certified the Renesas I3C bus extension merchandise for its MegaRAC SP-X Distant Administration Firmware. Having the I3C units on AMI’s authorised vendor record allows a straightforward migration path for patrons shifting their DDR5 platforms and boards from I2C or different legacy growth specs to the brand new high-speed I3C specification.

“The following-generation I3C interface meets business wants pushed by aggressive information centre development and elevated demand for safety infrastructure and extra environment friendly {hardware} in industrial, automotive, and telecommunications programs. AMI is proud to qualify these newest DDR5 I3C Bus Extension and SPD Hub Gadgets from Renesas in its MegaRAC SP-X Distant Administration Firmware,” stated Kelly Bryant, Chief Product Officer at AMI.

Renesas’ I3C units and analysis boards can be found now.
