On March 4, 2019, the USB promotion organization announced that,USB4The framework will arrive around the second half of 2019.USB4The protocol will be developed based on the Thunderbolt 3 protocol, with a transmission rate of up to 40Gbps and a maximum power supply of 100W. It can be connected to an external video card, two 4K displays or a single 5K display!And backward compatibleUSB3.2, USB2.0 standard and lightning 3.USB4The standard realizes the integration of underlying lightning and USB protocols, and enhances the compatibility between products based on USB Type-C interface.At the same time, Intel announced that it will open the lightning protocol specification to USB promotion organizations, and manufacturers can create chips and devices compatible with lightning standards for free.soUSB4It will be fully integrated with Thunderbolt 3 and become the next generation of high-speed data transmission specification.And, fromUSB3.2Start, includingUSB4The traditional USB-A and USB-B interfaces are completely abandoned, and Type-C will become the only one.
It is reported that HYNETEKHuinengtaiRecently, the latest generation of high voltage resistant electronic label chip (eMarker) has been launchedHUSB332。HUSB332A series of performance improvements and reliability improvements have been made for various applications and compatibility feedback from customers in the market.HUSB332It can be mounted on USB2.0 cable (5A cable), USB3.0 cable, USB3.1 cable,USB3.2Cable and 40Gbps cable.HUSB332The main features are as follows: • Get the latestUSB PD3.0 Certification, TID 875. • Remove the decoupling capacitance on the VCONN1 and VCONN2 pins, and zero the peripheral device scheme. • CC, VCONN1 and VCONN2 pins support 25V high-voltage protection. • It can support lightning 3 40Gbps high-speed data communication. • Support Modal Operation command. • Support the Get Manufacturer Info command. • Multiple burn and burn lock are optional.
HUSB332DFN-6L package is supported, with a size of 2 mm x 2 mm x 0.75 mm and a pipe spacing of 0.65 mm. More package types will be introduced in the future.
