TP5208
64K SRAM ECHO PROCESSOR
General Description
The TP5208 is a developed processor for producing
echo effects added to voice signals picked up by
microphone for karaoke applications. The IC has the
largest memory among the digital delay series.
As
its design is aimed at high performance, it is best
suited to provide radio cassette tape recorders and
miniature unit audio system with quality echo function.
With
pins
compatible
with
the

converters and memory realize a delay system
with only a single chip
Capable
of
composing
low-noise
and
low-distortion delay system at low cost by ADM
