Overview

The NU-NAUSB2I2C is a USB-to-I2C and I2S bridge control board specifically designed for the Nuvoton audio ecosystem. It serves as a hardware interface to control and configure Nuvoton audio amplifiers and codecs from a PC via USB. This board is essential for real-time tuning and debugging of audio signal processing chains in development environments.

Why Choose This Part

It provides a direct hardware-to-software link, allowing engineers to use Nuvoton GUI tools for graphical register configuration. The dual support for I2C control and I2S data makes it a versatile tool for both control plane and data plane debugging in audio systems.

Applications

Audio Codec Configuration
Setting internal register values for Nuvoton audio codecs during initial board bring-up and characterization.
Amplifier Tuning
Adjusting gain, EQ parameters, and protection thresholds in audio power amplifiers via I2C.
Digital Audio Prototyping
Utilizing the I2S interface to stream or monitor digital audio data during software development.
Production Calibration
Automating the programming of non-volatile settings in audio ICs on the production line.

Getting Started

Connect the NU-NAUSB2I2C to a host PC using a standard USB cable and bridge the I2C/I2S headers to your target Nuvoton audio evaluation board. Download the Nuvoton Audio Configuration tool or the specific GUI for your codec/amplifier to begin real-time register manipulation. Ensure the jumpers on the bridge board are correctly set for the target voltage levels of your application.

Also Consider

FT260 Evaluation Board FTDI Chip - A general-purpose USB to I2C/UART HID class bridge that does not require custom drivers for basic control tasks.
MCP2221A MCHPMicrochip Technology - A discrete IC alternative for designers who want to integrate USB-to-I2C/SMBus bridging directly onto their own custom prototype boards.
