LC823450XDTBG Product Details

LC823450XDTBG 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, LC823450XDTBG provides a significantly longer battery life without compromising audio quality, for voice recorders and wearable audio applications.
