REALTEK has long held a position in the fields of audio encoding and decoding, network communication, and consumer electronics chips. With the iteration of USB interface technology and changes in market demand, its USB conversion chip product line has demonstrated strong technological competitiveness and market adaptability. This article will analyze the current development status of Ruiyu USB conversion chips from three dimensions: technical architecture, application scenarios, and industry impact.

1、 Technical architecture: Multi protocol compatibility and low-power design

The core advantage of Ruiyu's USB conversion chip lies in its compatibility design with multiple interface protocols. Taking the RTU series as an example, this series of chips supports the conversion of USB 2.0/3.0 to UART, SPI, I2C and other parallel/serial interfaces, with a transmission rate of up to 5Gbps (USB 3.0 mode).

Low power design is another major technological highlight, with the RTU2100 series using a 28nm process. The standby power consumption is as low as 0.15mW, and the dynamic power consumption is controlled at 60% of similar products. This feature makes it widely popular in IoT terminal devices, such as smart home sensors that can extend battery life when firmware is upgraded through USB to SPI interface.

2、 Application scenarios: From consumer electronics to industrial automation

In the field of consumer electronics, REALTEK chips have become the core components of Type-C docking stations. In terms of industrial applications, the RTU4500 series has passed the wide temperature certification from -40 ℃ to 85 ℃, achieving stable conversion between USB and CAN buses in industrial PLC control systems.

3、 Market Impact: Reshaping the Interface Conversion Ecosystem

Ruiyu has significantly reduced the difficulty of peripheral circuit development through its "chip reference design" business model. The complete development kit it provides (including drivers, API interfaces, and PCB layout guidelines) shortens the customer's product development cycle by approximately 6 weeks.

In terms of segmented markets, its USB audio conversion chip performs particularly well. The RTL8156B chip supports 32bit/384kHz high-definition audio decoding with a signal-to-noise ratio of 120dB, and has been applied to multiple professional audio interface brands.

Throughout the development trajectory of REALTEK's USB conversion chips, the key to their success lies in accurately grasping the pace of interface standard evolution and achieving a balance between performance and cost. With the deepening of the Internet of Things era, such interface conversion chips will continue to play an important role as "digital bridges", and the depth of technological reserves and ecological construction will determine the position of enterprises in the next round of competition. For device manufacturers, choosing a chip solution with a complete technical support system has become a key guarantee for rapid product launch.
