LC823450 Audio Processing System LSI

onsemi LC823450 Audio Processing System LSI is designed to record, playback, and is capable of high-resolution 32-bit and 192kHz audio processing. It is possible to cover most of the functions necessary for portable audio with only this LSI. This device includes dual CPU and DSP and has high processing capability and internal 1656K-Byte SRAM. These features make it possible to implement a large-scale program. The LC823450 has integrated analog functions (low-power Class D HP amplifier, PLL, ADC, etc.) to reduce PCB space and cost. The device includes various interfaces (USB, SD, SPI, UART, etc.) to make extensibility high. The onsemi LC823450 provides multiple functions, including SBC/AAC codec by DSP and UART and ASRC (Asynchronous Sample Rate Converter) for BLUETOOTH® audio. This device comes in a very small chip size despite the available multi-functions, and it realizes low power consumption. Therefore, it is applicable to portable audio markets such as wireless headsets and will provide high performance.
