The
MLC1043 is a voice synthesis IC
with built-in EPROM for voice
data storage. This IC employs
MLPCM voice coding algorithm and
utilizes a low power CMOS technology
for portable applications.
*MLPCM : Advanced voice coding
method based on the modified ADPCM
algorithm that is developed by
MCS Logic. |
