ON Semiconductor LC823450XDTBG

Description
LC823450 is an ultralow power, 32bit, 192 kHz highresolution audiocapable signal processing systemonchip (SoC).
It consists of dual ARM CortexM3, 32bit DSP (LPDSP32) core, hard wired MP3 encoder/decoder, and integrated SRAM.
It is also equipped with analog peripheral functionality, such as PLLs, classD stereo HP amplifier, 6band 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 finetuned 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.
