General voice synthesizer
Toy controller
General IR controller
General Description
MLC0xxB series integrates an 8-bit CPU core,
SRAM, timer, D/A and system control circuits
by a CMOS silicon gate technology. The ROM
can store voice, melody, data table and
program.
Twenty-four I/O pins can be used for keypad
control, motor control, IR application, LED
indicators or communication with other
systems. This chip can implement a dual tone
melody function with programmable envelope,
which can perform harmonic music with
different timbres.
This chip is very suitable for instruments,
speech products, and intelligent educational
toys, etc.
