LC83015E

Digital Signal Processor

for Audio Applications

Overview

The LC83015E is a digital signal processor IC designed for

medium- and high-class home audio systems, such as AV

amplifiers, mini, super-mini and car audio component sys-

tems.

The LC83015E is a part of the LC83010N/NE family. It

features an internal ROM, with a large standard program

library, an internal RAM for user programs and a wide va-

riety of interface capabilities. The standard program library

includes sound-field simulation, theater surround and

karaoke programs.

The LC83015E operates from a 5V supply and is available

in 80-pin QFPs.
