STMicroelectronics AVAS Solution Based on SPC582B60E1

STMicroelectronics AVAS Solution Based on SPC582B60E1 is based on the SPC582B60E1 Chorus family MCU and FDA903D Class D audio amplifiers. These emit warning sounds to alert pedestrians of the presence of e-vehicles.  The AEK-AUD-C1D9031 integrates two audio amplifiers in stereo mode or two separate audio channels. The board’s compact size allows for strategically placing different modules around the vehicle to ensure that warning sounds can be heard along the entire vehicle length. All the modules are controlled by a central MCU via CAN interface. The embedded SPC582B60E1 microcontroller monitors and controls the two Class-D FDA903D power amplifiers driving the loudspeakers. The MCU sends the audio samples via the I2S bus and programs the amplifiers via an I2C interface.
