LC823450

LC823450  Low Power & High-Resolution Audio Processing System LSI for Portable Sound Solution Description LC823450 is an ultra−low power, 32−bit, 192 kHz high−resolution audio−capable signal processing system−on−chip (SoC). It consists of dual ARM Cortex−M3, 32−bit DSP (LPDSP32) core, hard wired MP3 encoder/decoder, and integrated SRAM. It is also equipped with analog peripheral functionality, such as PLLs, class−D stereo HP amplifier, 6−band equalizer and ADCs/DACs. Our proprietary LPDSP32 supports Noise/Echo cancellation, and playback speed control capability for MP3, WMA, AAC and PCM with VBR. With fine−tuned power management and dedicated hard wired audio blocks, LC823450 provides a significantly longer battery life without compromising audio quality, for voice recorders and wearable audio applications. This document describes features, basic functions, electrical specifications, characteristics, application diagram and package dimension of this LSI. Featur...
