CMOS IC
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 systems.
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 variety 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.
