4 Key Numbers to Understand the Newly Upgraded HUSB332E:

• 10226 —— The upgraded HUSB332E has officially passed USB-IF certification with TID number 10226, meeting the latest USB Type-C 2.4 and PD3.2 specifications to ensure seamless compatibility with mainstream devices.

• USB4 Gen4 and DP2.1 — The upgraded HUSB332E supports USB4 Gen4 and Thunderbolt 3/4/5, enabling C-to-C cable designs for 240W power delivery and 80Gbps data transfer. It also supports DP2.1 for lossless transmission of 4K and higher ultra-high-definition video.

• 0.45 mA — Standby power consumption as low as 0.45 mA, significantly below industry averages. Reduced energy consumption minimizes thermal risks.

• ±8 kV — ±8 kV HBM ESD rating delivers enhanced electrostatic protection, substantially improving system reliability.

Customization:

The upgraded HUSB332E supports the Get_Manufacturer_Info command, offering 22 bytes of freely programmable space for writing customized information such as manufacturer names and brand logos. This means:

✅ Your brand becomes “visible”—devices can identify cable origins

✅ Anti-counterfeiting and traceability made easier—eliminate knockoffs and protect genuine product rights

✅ Greater flexibility for custom services—bestowing a “digital identity” upon premium cables

The upgraded HUSB332E also supports manufacturer-customizable UVDM (Unstructured VDM) response functionality. Brand manufacturers can leverage private commands to achieve:

✅ Dynamic reporting of cable capabilities

✅ Intelligent device-side recognition and matching

Over-Temperature Protection

When using the upgraded HUSB332E cable for high-power transmission, if the cable port temperature reaches the OTP threshold (test setting: 90°C), over-temperature protection will activate. The OTP protection mechanism ensures that during periodic hiccup cycles, only 5V is output on the VBUS line, preventing high voltage conditions.
