onsemi LC823450 audio processing system LSI

LC823450 is audio processing system LSI for record and playback, and High-Resolution 32-bit & 192 kHz audio processing capable. It has Dual CPU and DSP with High processing capability, and internal 1656K-Byte SRAM, which make it possible to implement large scale program. And it has integrated analog functions (low-power Class D HP amplifier, PLL, ADC etc.) so that PCB space and cost is reduced, and it has various interface (USB, SD, SPI, UART, etc.) to make extensibility high. Also it is provided with various function including SBC/AAC codec by DSP and UART and ASRC for Bluetooth® audio.
