STMicroelectronics STEVAL-CCA030V1

Overview

STEVAL-CCA030V1 from STMicroelectronics is a 2.1-channel digital audio demonstration board built around the STA350BW Sound Terminal™ IC, integrating FFX® Class-D amplification, digital audio processing, and I²S/I²C interface control. It delivers 2×50 W into 6 Ω at 25 V, supports 32–192 kHz sample rates, and provides 100 dB SNR with programmable biquad EQ and anti-clipping modes for high-fidelity audio evaluation.

For engineers reviewing the STEVAL-CCA030V1 datasheet, STEVAL-CCA030V1 pinout, STEVAL-CCA030V1 application, or STEVAL-CCA030V1 equivalent, this board serves as a validated reference platform for rapid prototyping of compact, high-efficiency audio systems requiring digital gain control, crossover filtering, and DC-blocking high-pass configuration.

Technical Context

The board implements a complete 2.1-channel digital audio signal chain: I²S input feeds the STA350BW's integrated DSP core, which applies user-configurable biquad filters (up to 8 per channel), preset crossovers, and night-mode attenuation before driving the FFX® output stage. Control is handled via I²C with selectable slave address and fast coefficient bank recall.

Operating voltage spans 5–26 V, enabling flexible bench and system-level testing; the dual-board architecture separates the STA350BW evaluation section from the APWLink (STEVAL-CCA035V1) interface module, requiring APWorkbench software for full configuration and real-time parameter tuning.

FAQ

Is STEVAL-CCA030V1 a standalone audio board?

No. It requires the companion APWLink interface board (STEVAL-CCA035V1) for I²S and I²C connectivity, and mandatory use of ST's APWorkbench software for configuration, real-time control, and coefficient upload - no standalone operation is supported.

What audio interfaces does STEVAL-CCA030V1 support?

It supports only I²S for digital audio input and I²C for device control and configuration. No SPDIF, TDM, PDM, or analog inputs are implemented - the board is strictly a digital-in, amplified-out reference platform for the STA350BW.

Can the subwoofer channel be reconfigured as a full-range channel?

No. The STA350BW architecture fixes the third channel as a low-frequency path with dedicated crossover filtering; it cannot be reassigned as a full-range channel or used for stereo extension without modifying firmware - no such capability is documented or supported.

Does STEVAL-CCA030V1 include thermal management features?

Yes. The board integrates a heatsink on the STA350BW power stage and uses 2-oz copper PCB layers for enhanced thermal dissipation, enabling sustained 50 W/channel output under 25 V supply with ambient temperature ≤40 °C - no fan or forced-air cooling is required.
