LC823450
Low Power & High-Resolution
Audio Processing System LSI
for Portable Sound Solution
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 so that PCB space and
cost is reduced, and it has various interface to make extensibility high.
Also it is provided with various function including SBC/AAC codec by
DSP and UART and ASRC 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.
This document describes features, basic functions, electrical
specifications, characteristics, application diagram and package
dimension of this LSI.
