STMicroelectronics AVAS Solution Evaluation Board Based on SPC582B60E1 Chorus Family MCU and FDA903D Class D AEK-AUD-C1D9031

STMicroelectronics AEK-AUD-C1D9031 is an advanced AVAS (Acoustic Vehicle Alerting System) solution evaluation board based on the SPC582B60E1 Chorus family microcontroller unit (MCU) combined with FDA903D Class D automotive-grade audio amplifiers. This compact board, measuring 110 mm by 90 mm, is engineered to emit pedestrian warning sounds for electric vehicles, ensuring safety compliance and enhanced acoustic awareness in urban environments.

The solution integrates two FDA903D Class D audio amplifiers configured in stereo or separate audio channels, allowing installation at strategic locations around a vehicle to produce uniform warning signals along its entire length. The onboard SPC582B60E1 MCU controls sound generation and amplifier operation, providing sophisticated monitoring functions and diagnostics via a CAN bus interface.

Audio samples are transmitted through an I2S interface, while programming and real-time management of the amplifiers are executed via I2C communication. Key diagnostic features include a dedicated DC diagnostic interrupt pin, mute control, open load detection during playback, short circuit to Vᴄᴄ or ground diagnostics, output voltage and current sensing, and built-in thermal protection to enhance reliability.

This evaluation board is tailored for automotive applications requiring compact, efficient, and precise audio alert systems and supports compliance with relevant regulatory standards. Being RoHS and WEEE compliant, it aligns with environmental safety requirements. The product is included in STMicroelectronics' AutoDevKit initiative, facilitating integration within advanced development workflows.
