ASMedia(ASMedia Technology)Is a subsidiary of ASUS，Specially responsible for the design of various chips，Also TSMC(TSMC)28nmOne of the important customers on process node orders。

At a recent event，ASMediastated that its USB 4and PDThe main control chip has obtained USB-IFcertification，This is also the industry's first USB to receive this certification 4main control chip。

According to DigiTimesreport，ASMediaUSB 4and PDThe main control chip model is ASM4242and ASM2464PD，It is still unclear what type of device it is designed for，The latter should have USB PDPower delivery capability，This means there is no need to add any additional chips，Making product design simpler。ASMediaIndicates，Its USB 4and PDThe main control chip has provided samples to customers for verification，Both solutions are expected to pass the verification phase this year。

It is reported，ASM4242Has PCIe 4.0 x4Interface，Can support up to 64 GbpsBandwidth。But，Since this is a dual-port controller，It is still insufficient for both ports to be USB4 Gen 3x2The supported full 40 GbpsRun，But even so，Its speed is already sufficient for most ordinary consumers。

ASMediaAlso added support for DP Alt ModeSupport，USB 4Of course, it is also backwards compatible with Thunderbolt 3,While ASMedia Already providing samples to its partners for engineering evaluation，Although USB4The standard, as early as 2019Year 9It was born that month，But until early this year，AMDRyzen 6000The series is the first to support，And to this day，There are still no actual products。

Now，ASMedia has accomplished the world's first USB4Main controller，Model“ASM4242”，Has passed USB-IFThe organization's official certification，Releasing related products is just around the corner。In the future, perhaps all devices can have a unified interface,Whether it's graphics cards or memory，USB4Cable orders should also begin to ramp up in line with customer demand。
