I. USB Audio Products: High-Definition, Lossless, Low-Latency Audio Transmission Solutions

Renesas’ USB audio product series is specifically designed for high-definition audio transmission and playback scenarios, focusing on the requirements of both consumer and industrial-grade audio equipment. It addresses the pain points associated with traditional audio interfaces—such as transmission distortion, high latency and poor compatibility—by supporting standardised USB audio protocols and offering plug-and-play compatibility across multiple systems. With no need for complex driver configuration, it significantly lowers the product development threshold.

1. Key Product Features

This product series supports the USB Audio Class 1.0/2.0 standards and is compatible with mainstream operating systems such as Windows, Android, Linux and macOS. It features high-fidelity audio sampling capabilities, enabling high-definition audio decoding and output at up to 24-bit/192 kHz, faithfully reproducing the original audio details. It also incorporates Renesas’ proprietary low-latency audio processing algorithm, which effectively reduces audio transmission latency and eliminates audio-visual desynchronisation, making it suitable for scenarios such as multimedia playback, gaming audio and real-time voice interaction.

In terms of hardware design, the product integrates an audio DAC/ADC, noise-reduction circuitry and a power amplifier module, achieving a high degree of integration. This significantly reduces the number of external components, streamlines the PCB layout, and lowers both power consumption and production costs. With built-in multi-stage noise reduction, echo cancellation and gain adjustment functions, it effectively suppresses ambient noise and transmission interference, ensuring the purity of audio output and meeting the dual requirements of consumer-grade high-definition audio and industrial-grade voice capture. Furthermore, the entire product range supports both bus-powered and self-powered modes, catering to the different power supply scenarios of portable and fixed devices.

2. Typical Application Scenarios

Widely used in products such as USB headphones, gaming headsets, external USB sound cards, desktop audio systems, in-car USB audio players, smart speakers and conference audio equipment. Thanks to their stable transmission performance and outstanding audio quality, Renesas’ USB audio chips have become the preferred core solution for mid- to high-end consumer audio devices and commercial voice equipment.

II. USB Host and Hub Products: High-Speed Expansion, a Stable and Reliable Interconnection Core

Renesas’ USB host and hub series provides core solutions for device interface expansion and high-speed interconnectivity. It comprises two key product categories: USB host controllers and multi-port hub chips. Compatible with mainstream transmission protocols such as USB 2.0 and USB 3.2 Gen1, the series balances high-speed data transfer, multi-port expansion and ultra-low power consumption, perfectly meeting the interface expansion requirements of desktop devices, industrial equipment and portable expansion accessories.

1. Key Product Advantages and Representative Models

A leading representative product, the UPD720201, is a high-performance 7-port USB 3.2 Gen1 (5 Gbps) hub controller. It enables rapid expansion of a device’s USB interfaces via a PCIe x1 slot, supporting simultaneous high-speed data transfer across multiple ports. Each port features independent bandwidth without contention, significantly enhancing a device’s peripheral expansion capabilities. This chip supports flexible switching between USB host and device modes, making it suitable for a wide range of product forms, including host controllers, docking stations and industrial hubs.

The entire range of hub products features comprehensive port protection mechanisms, with built-in overcurrent, overvoltage and short-circuit protection functions, which effectively prevent device damage caused by peripheral faults and enhance the overall operational stability of the system. It also supports intelligent power management features such as port sleep mode and individual power-off control; idle ports automatically enter low-power mode, effectively reducing the system’s energy consumption and meeting the requirements of both industrial 24-hour continuous operation and the low-power demands of portable devices.
