Product details

Overview

AEKD-STEREOAVAS from STMicroelectronics is an AutoDevKit evaluation kit for acoustic vehicle alerting systems (AVAS), comprising AEK-AUD-C1D9031 (FDA903D Class D audio amplifier + SPC582B60E1 MCU), AEK-MCU-C4MLIT1 domain controller, two AEK-LCD-DT028V1 display boards, dual integrated loudspeakers, hardware mute button, and speaker disconnection switch - deployed in e-vehicle compliance testing and driver interface validation.

For engineers reviewing the AEKD-STEREOAVAS datasheet, AEKD-STEREOAVAS pinout, AEKD-STEREOAVAS application, or AEKD-STEREOAVAS equivalent, key considerations include CAN-based command exchange between controller and AVAS ECU, open-load detection during play/mute states, resistive-touch GUI for RPM/sound control, and stereo Class D amplification with hardware safety features.

Technical Context

The kit implements a functional AVAS demo using CAN protocol for real-time start/stop command exchange between AEK-MCU-C4MLIT1 (SPC5 Chorus 4M automotive MCU) and AEK-AUD-C1D9031 (FDA903D audio amplifier with embedded open-load detection). Audio playback is driven by preloaded WAV files mapped to car key-on, neutral, and drive modes.

Two AEK-LCD-DT028V1 boards provide resistive-touch HMI: one displays simulated motor RPMs, the other enables volume adjustment, demo start/stop, and RPM regulation. Hardware mute and speaker disconnect switches trigger dedicated LED indicators (orange D7 for mute, blue for open-load detection).

FAQ

What is the primary function of the AEKD-STEREOAVAS kit?

The AEKD-STEREOAVAS is a complete evaluation platform for Acoustic Vehicle Alerting Systems, demonstrating stereo audio generation, CAN-based vehicle-state-triggered playback, real-time HMI feedback, and hardware-level safety monitoring including open-load detection and hardware mute - all compliant with EU AVAS regulations for electric vehicles.

Which microcontroller and audio amplifier are used in the core AVAS board?

The AEK-AUD-C1D9031 board integrates the SPC582B60E1 Chorus-family automotive MCU and FDA903D Class D audio amplifier. The MCU handles CAN communication and system control, while the FDA903D delivers stereo output with embedded current-sensing circuitry for open-load detection during both active and muted operation.

How does the open-load detection feature operate?

Open-load detection is implemented via current sensing in the FDA903D amplifier. When the speaker disconnect switch is toggled, the system monitors load impedance during playback or hardware mute; if no current flow is detected, the blue LED illuminates. Detection sensitivity depends on output amplitude - volume must be sufficiently high for reliable triggering.

Can the preloaded audio files be replaced or customized?

The kit ships with fixed WAV files mapped to key-on, neutral, and drive states. While the firmware supports CAN-triggered playback, audio file replacement requires reprogramming the AEK-AUD-C1D9031's internal flash memory using ST's SPC5 Studio IDE and compatible debug tools - no SD card or external storage interface is provided on the board.
