USB for Inside the Box: eUSB2 and eUSB2V2 (Download)
If eUSB2 — or its newer variant, eUSB2V2 — is new to you, you’re not alone. These USB-based interfaces are still emerging, but they matter now more than ever to engineers building 5-nm and more advanced SoCs, or connecting one of these chips to a more mature-node companion. They’re particularly relevant in edge AI and other embedded systems, where massive amounts of data pinball between components.
At a high level, eUSB2 is USB 2.0 reworked for the demands of modern silicon. eUSB2 was introduced through the efforts of the USB-IF to modernize the USB 2.0 standard, starting in the mid-2010s.
