The AT6901 is a highly integrated DSP (Digital Signal Processor) for audio system. The AT6901
integrates a Xtensa-HIFI5 audio DSP with FPU and an ultra-low power NPU (neural network
processor) based on precision lossless SRAM Computing in Memory (CIM) . Including up to 8
channels D-MIC interface with decimation filters, and 4 channels A-MIC with high performance ADC, stereo high performance DAC. It integrates I2S/TDM compatible audio interfaces, which can support
80 channels input and 80 channels output. It also integrates a high-performance ASRC with 8 channels, and THD+N is less than -140dB. The AT6901 also integrates a 32bit ARM STAR-MC1 CPU as the
application processor to maintain system control and peripheral interfaces. Large capacity RAM is
embedded to meet different automotive audio applications.
