VOICE SYNTHESIS LSI with External ROM
MLC1036
1.
General Description
The MLC1036 is a voice synthesis IC with external MASK ROM, EPROM, or Flash Memory for voice storage.
This IC employs MLPCM voice coding algorithm and utilizes a low power CMOS technology for portable applications.
Since it has a built-in current mode 12-bit DA converter and digitally adjusted low pass filter, any kind of human voice or special sound output can be easily accomplished by using a few pieces of external components.
MLC1036 has simple MCU interface type control method.
Therefore, users can easily
