Low Power & High-Resolution Audio Processing System-on-Chip (SoC)
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.
