The Department of Trade and Industry’s Bureau of Philippine Standards (DTI-BPS) approved the adoption of the International Electrotechnical Commission (IEC) Standard on Universal Serial Bus, as a Philippine National Standard (PNS IEC 62680-3-1:2019).

The PNS IEC 62680-3-1:2019 Universal Serial Bus interfaces for data and power – Part 3-1: Universal Serial Bus 3.1 Specification describes the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this specification. USB 3.1 is primarily a performance enhancement to SuperSpeed USB 3.0 resulting in providing more than double the bandwidth for devices such as Solid State Drives and High Definition displays.

The Universal Serial Bus (USB) provides a user-friendly plug-and-play way to attach external peripherals to Personal Computer (PC). Further, it is used in many non-traditional applications, such as industrial automation, and USB as a source of power has become the mobile device charging solutions across the globe. As PCs became increasingly powerful and able to process larger amounts of data, users needed to get more and more data into and out of their PCs. USB 3.0 was the USB community’s response and provided users with the ability to move data.

With the continued trend for more bandwidth driven by larger and faster storage solutions, higher resolution video, and broader use of USB as an external expansion/docking solution, USB 3.1 extends the performance range of USB up to 1 GB/s by doubling the SuperSpeed USB and enhancing data encoding efficiency.

USB 3.1 enable devices to interoperate in an open architecture, while maintaining and leveraging the existing USB infrastructure (device drivers, software interfaces, etc.). The specification is intended as an enhancement to the PC architecture, spanning portable, business desktop, and home environments, as well as simple device-to-device communications. It is intended that the specification allow system OEMs and peripheral developers adequate room for product versatility and market differentiation without the burden of carrying obsolete interfaces or losing compatibility.

The DTI-BPS is the National Standards Body of the Philippines. It is the Philippines’ member to the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
