STA321MP General Description

DescriptionThe STA321MP is a PDM high-performance multichannel processor with ultra-low quiescent current designed for general-purpose digital microphone applications. The device is fully digital and is comprised of three main sections. The first section is the PDM input interface which canaccept up to six serial digital inputs. The second section is a high-quality audio processor allowingflexible channel mixing/muxing and provides up to 10 biquads for general sound equalization andvoice enhancement with independent volume control.Features■ 8 digital processing channels each 24-bit– 6 channels of PDM input– 2 additional virtual channels■>100 dB SNR and dynamic range■ Digital gain/attenuation +58 dB to -100 dB in 0.5 dB steps■ Soft volume update■ Individual channel and master level control■ Up to 10 independent 32-bit userprogrammable biquads (EQ) per channel■ Bass/treble tone control■ Pre- and post-EQ full 8-channel input mix on all 8 channels■ Dual independent limiters/compressors■ Dynamic range compression or anti-clipping modes■ Individual channel and master soft/hard mute■ 3 I2S data outputs■ I2S data output channel mapping function■ Independent channel volume and DSP bypass■ Channel mapping of any input to any processing channel
