    產(chǎn)品信息

    LC823450 is audio processing system LSI for record and playback, and High-Resolution 32-bit & 192 kHz audio processing capable. It is possible to cover the most of functions necessary for a portable audio with only this LSI as follows. 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 includingSBC/AAC codec by DSP and UART and ASRC (Asynchronous Sample Rate Converter) for Bluetooth? audio. It is very small chip size in spite of the multi-funciton as described above and it realizes the low power consumption. Therefore, it is applicable to porable audio markets such as Wireless headsets and will show high performance.
