The
MLC103X series are voice synthesis
LSI with built-in MASK ROM for
voice data storage. This 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 |
