M31 Technology’s USB 3.1 and USB 3.0 PHY are with the feature in fully compliance to the latest specification of USB TYPE-C connector. To save the total design space and an extra cost of external high-speed switch, both USB 3.1 and USB 3.0 TYPE-C PHY are designed with built-in high-speed switch for non-directional plug-and-play connections.

M31’s new-generation USB 3.1 and USB 3.0 TYPE-C PHY have been adopted by many tier-one fabless IC design companies and their products have been successfully massively produced.

USB2.0 interface has been an industry standard and ubiquitous for electronic systems for many years. To ride on the popularity of USB2.0, M31 further enhanced and optimized its next generation micro USB 2.0 PHY to achieve over 50% saving in area and 30% reduction in power. In addition to the optimal electrical performance, this new version of micro USB 2.0 PHY has passed the USB-IF Compatibility Tests to speed up some of customer’s designs to mass production.

M31’s patented BCK (Built-in-Clock, a.k.a. Crystal-less) technology is an innovative way to save BOM (Bill of Materials) cost by reducing an external crystal for mobile USB devices.

In general, this solution has been popularly adopted by those USB devices in applications like flash drive, wireless transmitter, sound card, webcam, etc. BCK technology does not only support the USB 1.1/2.0/3.0 devices by recovering the clock from the host data, but it also could act as a clock sourcing block to the USB host, like MCU, by dividing the clock with input frequency of 32.768KHz. BCK technology, implemented specifically in low power, could be extensively applied for most IoT products.

H.P. Lin, M31 Technology's Chairman said: "M31 has developed a family of USB PHY in 28nm, 40nm and 55nm processes, and these solutions are designed with key features of lower power, full standard compatibility and optimized performance.

Instead of supporting in bits and pieces, M31 is committed to provide a full set of solutions, by actively investing and participating in various foundries’ IP certifications and numerous USB-IF compatibility tests to support our customers globally with distinguished and differentiated features, and professional services”.

With its smallest area, production proven quality, and supports in a full spectrum (from matured to advanced) of process nodes, M31’s USB3.0 PHY have been adopted globally by many IC design customers, with the expectation that M31’s IP solutions could minimize their design risks and shorten the time-to-market of their products.
