Low Power &

High-Resolution Audio

Processing System LSI

for Portable Sound Solution

www.onsemi.com

Description

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

TQFP128 14 x 14/ TQFP128L

CASE 932BA

SBC/AAC codec by DSP and UART and ASRC for Bluetooth audio.

It is very small chip size in spite of the multi−function as described

above and it realizes the low power consumption. Therefore, it is

applicable to portable audio markets such as Wireless headsets and

will show high performance.

WLCSP154 5.52 x 5.33

CASE 567LD

This document describes features, basic functions, electrical

specifications, characteristics, application diagram and package

dimension of this LSI.
