One chip sound solution "CRI SOLIDAS"

Product Catalog

This fully digital audio solution enables software-based audio signal processing for microcontrollers/FPGAs, enabling the development of a variety of audio equipment.

"CRI SOLIDAS" realizes various audio equipment with one chip by equipping general-purpose microcontrollers / FPGAs with software audio signal processing.

6 benefits
- Supports audio output using the power-saving "CRI D-Amp Driver"

The unique output method consumes about half the power compared to a general-purpose D-class amplifier when outputting at the same volume

- Multi-channel realized with one chip

Since 2 to 4 PWM outputs built into the general-purpose microcontroller can output 1 channel of audio, multi-channel output can be realized with one chip

- Low noise and high sound quality brought by the unique output method

Since it is output by differential drive, noise at the time of speaker output is reduced. In addition, since no current flows through the speaker when there is no sound, there is only residual noise at the limit of measurement.

- Use of generic parts & reduction in number of parts reduces risk

Audio processing and output are realized with a generic 1-chip + H-bridge circuit, so it is configured with generic parts.

- Sound system developed with low code

We have a set of GUI tools that provide total support for the design of sound systems. From configuring the DSP to creating block diagrams of peripheral circuits, design work is completed on the GUI.

- Flexibility of development and technology transfer

Developing with GUI tools makes it easier to develop flexibly and transfer technology.
