STMicroelectronics STEVAL-CCA053V1

Overview

STEVAL-CCA053V1 from STMicroelectronics is an evaluation board designed to demonstrate the STA333IS Sound Terminal® 2-channel high-efficiency digital audio system IC. It implements a full-digital stereo Class-D amplifier solution with FFX™ ternary PWM output, supporting 32–192 kHz I²S input, 100 dB SNR, and up to 10 W + 10 W into 8 Ω in BTL mode. The board enables rapid validation of audio processing, thermal management, and AM interference suppression features in compact consumer audio systems.

For engineers reviewing the STEVAL-CCA053V1 datasheet, STEVAL-CCA053V1 pinout, STEVAL-CCA053V1 application, or STEVAL-CCA053V1 equivalent, this page provides verified hardware configuration details, supported interfaces (I²S, I²C), power supply requirements (4.5–20 V analog, 3.3 V digital), thermal design guidance, and real-world implementation constraints for LCD/DVD speaker integration.

Technical Context

The STEVAL-CCA053V1 implements the STA333IS in a fully populated, ready-to-run configuration with dual half-bridge outputs per channel, integrated DC-cut filtering (2 Hz), and hardware-configurable EAPD control. It routes all I²S (LRCKI, BICKI, SDI), I²C (SCL/SDA), and master clock (XTI) signals to accessible headers, while providing dedicated test points for OUT1A/OUT1B/OUT2A/OUT2B, VCCx, GNDx, and thermal warning signals.

Board-level design includes optimized PCB layout for EMI reduction-featuring split ground planes, localized decoupling (10 µF + 100 nF per VCC rail), thermal vias under the CSP-5×6 package, and ferrite-bead-filtered VDD_DIG/VDD_PLL supplies. It supports both software-controlled volume (–80 dB to +48 dB) and hardware mute via dedicated pins, with automatic zero-detect and invalid-input mute enabled by default.

FAQ

What power supply configuration is required to operate STEVAL-CCA053V1?

The board requires a single 4.5–20 V DC input applied to the main VCC terminals, which internally generates regulated 3.3 V rails for digital, PLL, and reference supplies. No external 3.3 V source is needed-the onboard LDOs (VDD_DIG, VDD_PLL, VDDREG) are powered from VCC and include ceramic decoupling. Current draw is ≤200 µA in power-down and scales with output power and sampling rate.

Does STEVAL-CCA053V1 support hardware-based mute and EAPD control?

Yes. The board exposes dedicated hardware mute (MUTE pin) and EAPD (External Amplifier Power Down) signals via JP1 header. EAPD can be asserted low to disable output stage switching while preserving digital core operation, enabling fast wake-up. Mute is active-low and synchronized to zero-crossing for pop-free transitions.

Can the AM interference suppression modes be configured without firmware changes?

No-Automodes™ settings (AM switching frequency, noise-shaper bandwidth, PWM speed mode) are controlled exclusively via I²C registers (e.g., addr 0x0C, 0x29–0x2A). The board provides no DIP switches or jumpers for analog configuration; all tuning requires register writes using ST's official GUI or custom host controller code.

Are schematic and PCB layout files available for STEVAL-CCA053V1?

Yes. STMicroelectronics publishes complete design resources-including schematic (PDF), PCB layout (Gerber), bill of materials (XLS), and assembly drawings-for STEVAL-CCA053V1 under document number CD002431.
