Keywords: USB3.0 master chip universal interface standard intelligent power management USB3.0 is the most popular universal interface standard in the past two years, continuing the great success of USB2.0, USB3.0 interface has entered the high-end desktop In the computer and notebook computer market, AMD this year and next year Intel will integrate the USB3.0 main control chip into the chipset. It is just around the corner that USB3.0 will become the mainstream of the market.

However, the USB3.0 main control chips of all computers are still provided by third-party chip manufacturers. The only USB3.0 main control chips certified by USB-IF are products from Renesas (formerly NEC) and Ruisi Technology. There are so few manufacturers that can pass the certification, which shows that there is great difficulty in technology.

Zhang Jinfan, President of Ruisi Technology, revealed: "To pass the USB-IF certification, a lot of compatibility tests are required to ensure compatibility with most USB2.0 devices on the market. This work is very complicated, so currently only our two can Passed certification." As a start-up company can have such strong technical strength, its main members are all from Intel, and even two employees are members of the expert group that formulated the USB3.0 specification, so in terms of main control chip Can have such an outstanding performance.

This small manufacturer specializing in USB3.0 main control chip, exhibited at this IIC exhibition is the latest USB3.0 main control chip FL1009, which not only has up to 393MB/s, the fastest read and write transmission performance in the world, At the same time, it is currently the only master chip that supports isochronous transfer of uncompressed 1080p/60 frames full HD.

In addition, Ruisi Technology’s solution can tolerate trace lengths of up to 23 cm, reducing the attenuation of the signal on the PCB, releasing the limitations of the system design in the circuit layout, and allowing trace lengths up to 45 cm The additional wiring of the USB3.0 on the front panel does not require the cost of additional ReDriver signal conditioning chips, enabling system vendors and board vendors to create products with the highest performance and effectively reducing design time and costs.

Because FL1009 is based on a hardware accelerator and does not need a built-in microprocessor, plus the low-power intelligent power management technology of the main control chip, the main control chip of Ruisi can achieve extremely low power consumption regardless of whether it is used at full speed or in sleep mode. In 2010 The USB-IF Association even listed Ruisi's main control chip as the reference standard for low-power power management testing on the peripheral side.

Since chipset manufacturers will integrate the USB3.0 main control chip into the South Bridge chip in the future, Ruisi Technology is also targeting the consumer electronics and mobile device markets. This year has begun to cooperate with TV manufacturers to allow smart TVs to directly support the USB3.0 interface.
